+GNU GENERAL PUBLIC LICENSE
+
+Version 3, 29 June 2007
+
+Copyright © 2007 Free Software Foundation, Inc. <http s ://fsf.org/>
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The GNU General Public License is a free, copyleft license for software and
+other kinds of works.
+
+The licenses for most software and other practical works are designed to take
+away your freedom to share and change the works. By contrast, the GNU General
+Public License is intended to guarantee your freedom to share and change all
+versions of a program--to make sure it remains free software for all its users.
+We, the Free Software Foundation, use the GNU General Public License for most
+of our software; it applies also to any other work released this way by its
+authors. You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for them if you wish), that
+you receive source code or can get it if you want it, that you can change
+the software or use pieces of it in new free programs, and that you know you
+can do these things.
+
+To protect your rights, we need to prevent others from denying you these rights
+or asking you to surrender the rights. Therefore, you have certain responsibilities
+if you distribute copies of the software, or if you modify it: responsibilities
+to respect the freedom of others.
+
+For example, if you distribute copies of such a program, whether gratis or
+for a fee, you must pass on to the recipients the same freedoms that you received.
+You must make sure that they, too, receive or can get the source code. And
+you must show them these terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps: (1) assert
+copyright on the software, and (2) offer you this License giving you legal
+permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains that
+there is no warranty for this free software. For both users' and authors'
+sake, the GPL requires that modified versions be marked as changed, so that
+their problems will not be attributed erroneously to authors of previous versions.
+
+Some devices are designed to deny users access to install or run modified
+versions of the software inside them, although the manufacturer can do so.
+This is fundamentally incompatible with the aim of protecting users' freedom
+to change the software. The systematic pattern of such abuse occurs in the
+area of products for individuals to use, which is precisely where it is most
+unacceptable. Therefore, we have designed this version of the GPL to prohibit
+the practice for those products. If such problems arise substantially in other
+domains, we stand ready to extend this provision to those domains in future
+versions of the GPL, as needed to protect the freedom of users.
+
+Finally, every program is threatened constantly by software patents. States
+should not allow patents to restrict development and use of software on general-purpose
+computers, but in those that do, we wish to avoid the special danger that
+patents applied to a free program could make it effectively proprietary. To
+prevent this, the GPL assures that patents cannot be used to render the program
+non-free.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+TERMS AND CONDITIONS
+
+   0. Definitions.
+
+   "This License" refers to version 3 of the GNU General Public License.
+
+"Copyright" also means copyright-like laws that apply to other kinds of works,
+such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this License.
+Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals
+or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work in
+a fashion requiring copyright permission, other than the making of an exact
+copy. The resulting work is called a "modified version" of the earlier work
+or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based on the
+Program.
+
+To "propagate" a work means to do anything with it that, without permission,
+would make you directly or secondarily liable for infringement under applicable
+copyright law, except executing it on a computer or modifying a private copy.
+Propagation includes copying, distribution (with or without modification),
+making available to the public, and in some countries other activities as
+well.
+
+To "convey" a work means any kind of propagation that enables other parties
+to make or receive copies. Mere interaction with a user through a computer
+network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays "Appropriate Legal Notices" to the
+extent that it includes a convenient and prominently visible feature that
+(1) displays an appropriate copyright notice, and (2) tells the user that
+there is no warranty for the work (except to the extent that warranties are
+provided), that licensees may convey the work under this License, and how
+to view a copy of this License. If the interface presents a list of user commands
+or options, such as a menu, a prominent item in the list meets this criterion.
+
+   1. Source Code.
+
+The "source code" for a work means the preferred form of the work for making
+modifications to it. "Object code" means any non-source form of a work.
+
+A "Standard Interface" means an interface that either is an official standard
+defined by a recognized standards body, or, in the case of interfaces specified
+for a particular programming language, one that is widely used among developers
+working in that language.
+
+The "System Libraries" of an executable work include anything, other than
+the work as a whole, that (a) is included in the normal form of packaging
+a Major Component, but which is not part of that Major Component, and (b)
+serves only to enable use of the work with that Major Component, or to implement
+a Standard Interface for which an implementation is available to the public
+in source code form. A "Major Component", in this context, means a major essential
+component (kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to produce
+the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all the source
+code needed to generate, install, and (for an executable work) run the object
+code and to modify the work, including scripts to control those activities.
+However, it does not include the work's System Libraries, or general-purpose
+tools or generally available free programs which are used unmodified in performing
+those activities but which are not part of the work. For example, Corresponding
+Source includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically linked
+subprograms that the work is specifically designed to require, such as by
+intimate data communication or control flow between those subprograms and
+other parts of the work.
+
+The Corresponding Source need not include anything that users can regenerate
+automatically from other parts of the Corresponding Source.
+
+   The Corresponding Source for a work in source code form is that same work.
+
+   2. Basic Permissions.
+
+All rights granted under this License are granted for the term of copyright
+on the Program, and are irrevocable provided the stated conditions are met.
+This License explicitly affirms your unlimited permission to run the unmodified
+Program. The output from running a covered work is covered by this License
+only if the output, given its content, constitutes a covered work. This License
+acknowledges your rights of fair use or other equivalent, as provided by copyright
+law.
+
+You may make, run and propagate covered works that you do not convey, without
+conditions so long as your license otherwise remains in force. You may convey
+covered works to others for the sole purpose of having them make modifications
+exclusively for you, or provide you with facilities for running those works,
+provided that you comply with the terms of this License in conveying all material
+for which you do not control copyright. Those thus making or running the covered
+works for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of your copyrighted
+material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the conditions
+stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
+
+   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological measure
+under any applicable law fulfilling obligations under article 11 of the WIPO
+copyright treaty adopted on 20 December 1996, or similar laws prohibiting
+or restricting circumvention of such measures.
+
+When you convey a covered work, you waive any legal power to forbid circumvention
+of technological measures to the extent such circumvention is effected by
+exercising rights under this License with respect to the covered work, and
+you disclaim any intention to limit operation or modification of the work
+as a means of enforcing, against the work's users, your or third parties'
+legal rights to forbid circumvention of technological measures.
+
+   4. Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you receive
+it, in any medium, provided that you conspicuously and appropriately publish
+on each copy an appropriate copyright notice; keep intact all notices stating
+that this License and any non-permissive terms added in accord with section
+7 apply to the code; keep intact all notices of the absence of any warranty;
+and give all recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey, and you
+may offer support or warranty protection for a fee.
+
+   5. Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to produce
+it from the Program, in the form of source code under the terms of section
+4, provided that you also meet all of these conditions:
+
+a) The work must carry prominent notices stating that you modified it, and
+giving a relevant date.
+
+b) The work must carry prominent notices stating that it is released under
+this License and any conditions added under section 7. This requirement modifies
+the requirement in section 4 to "keep intact all notices".
+
+c) You must license the entire work, as a whole, under this License to anyone
+who comes into possession of a copy. This License will therefore apply, along
+with any applicable section 7 additional terms, to the whole of the work,
+and all its parts, regardless of how they are packaged. This License gives
+no permission to license the work in any other way, but it does not invalidate
+such permission if you have separately received it.
+
+d) If the work has interactive user interfaces, each must display Appropriate
+Legal Notices; however, if the Program has interactive interfaces that do
+not display Appropriate Legal Notices, your work need not make them do so.
+
+A compilation of a covered work with other separate and independent works,
+which are not by their nature extensions of the covered work, and which are
+not combined with it such as to form a larger program, in or on a volume of
+a storage or distribution medium, is called an "aggregate" if the compilation
+and its resulting copyright are not used to limit the access or legal rights
+of the compilation's users beyond what the individual works permit. Inclusion
+of a covered work in an aggregate does not cause this License to apply to
+the other parts of the aggregate.
+
+   6. Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of sections
+4 and 5, provided that you also convey the machine-readable Corresponding
+Source under the terms of this License, in one of these ways:
+
+a) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by the Corresponding Source fixed
+on a durable physical medium customarily used for software interchange.
+
+b) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by a written offer, valid for
+at least three years and valid for as long as you offer spare parts or customer
+support for that product model, to give anyone who possesses the object code
+either (1) a copy of the Corresponding Source for all the software in the
+product that is covered by this License, on a durable physical medium customarily
+used for software interchange, for a price no more than your reasonable cost
+of physically performing this conveying of source, or (2) access to copy the
+Corresponding Source from a network server at no charge.
+
+c) Convey individual copies of the object code with a copy of the written
+offer to provide the Corresponding Source. This alternative is allowed only
+occasionally and noncommercially, and only if you received the object code
+with such an offer, in accord with subsection 6b.
+
+d) Convey the object code by offering access from a designated place (gratis
+or for a charge), and offer equivalent access to the Corresponding Source
+in the same way through the same place at no further charge. You need not
+require recipients to copy the Corresponding Source along with the object
+code. If the place to copy the object code is a network server, the Corresponding
+Source may be on a different server (operated by you or a third party) that
+supports equivalent copying facilities, provided you maintain clear directions
+next to the object code saying where to find the Corresponding Source. Regardless
+of what server hosts the Corresponding Source, you remain obligated to ensure
+that it is available for as long as needed to satisfy these requirements.
+
+e) Convey the object code using peer-to-peer transmission, provided you inform
+other peers where the object code and Corresponding Source of the work are
+being offered to the general public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded from
+the Corresponding Source as a System Library, need not be included in conveying
+the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any tangible
+personal property which is normally used for personal, family, or household
+purposes, or (2) anything designed or sold for incorporation into a dwelling.
+In determining whether a product is a consumer product, doubtful cases shall
+be resolved in favor of coverage. For a particular product received by a particular
+user, "normally used" refers to a typical or common use of that class of product,
+regardless of the status of the particular user or of the way in which the
+particular user actually uses, or expects or is expected to use, the product.
+A product is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent the
+only significant mode of use of the product.
+
+"Installation Information" for a User Product means any methods, procedures,
+authorization keys, or other information required to install and execute modified
+versions of a covered work in that User Product from a modified version of
+its Corresponding Source. The information must suffice to ensure that the
+continued functioning of the modified object code is in no case prevented
+or interfered with solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or specifically
+for use in, a User Product, and the conveying occurs as part of a transaction
+in which the right of possession and use of the User Product is transferred
+to the recipient in perpetuity or for a fixed term (regardless of how the
+transaction is characterized), the Corresponding Source conveyed under this
+section must be accompanied by the Installation Information. But this requirement
+does not apply if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has been installed
+in ROM).
+
+The requirement to provide Installation Information does not include a requirement
+to continue to provide support service, warranty, or updates for a work that
+has been modified or installed by the recipient, or for the User Product in
+which it has been modified or installed. Access to a network may be denied
+when the modification itself materially and adversely affects the operation
+of the network or violates the rules and protocols for communication across
+the network.
+
+Corresponding Source conveyed, and Installation Information provided, in accord
+with this section must be in a format that is publicly documented (and with
+an implementation available to the public in source code form), and must require
+no special password or key for unpacking, reading or copying.
+
+   7. Additional Terms.
+
+"Additional permissions" are terms that supplement the terms of this License
+by making exceptions from one or more of its conditions. Additional permissions
+that are applicable to the entire Program shall be treated as though they
+were included in this License, to the extent that they are valid under applicable
+law. If additional permissions apply only to part of the Program, that part
+may be used separately under those permissions, but the entire Program remains
+governed by this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option remove any
+additional permissions from that copy, or from any part of it. (Additional
+permissions may be written to require their own removal in certain cases when
+you modify the work.) You may place additional permissions on material, added
+by you to a covered work, for which you have or can give appropriate copyright
+permission.
+
+Notwithstanding any other provision of this License, for material you add
+to a covered work, you may (if authorized by the copyright holders of that
+material) supplement the terms of this License with terms:
+
+a) Disclaiming warranty or limiting liability differently from the terms of
+sections 15 and 16 of this License; or
+
+b) Requiring preservation of specified reasonable legal notices or author
+attributions in that material or in the Appropriate Legal Notices displayed
+by works containing it; or
+
+c) Prohibiting misrepresentation of the origin of that material, or requiring
+that modified versions of such material be marked in reasonable ways as different
+from the original version; or
+
+d) Limiting the use for publicity purposes of names of licensors or authors
+of the material; or
+
+e) Declining to grant rights under trademark law for use of some trade names,
+trademarks, or service marks; or
+
+f) Requiring indemnification of licensors and authors of that material by
+anyone who conveys the material (or modified versions of it) with contractual
+assumptions of liability to the recipient, for any liability that these contractual
+assumptions directly impose on those licensors and authors.
+
+All other non-permissive additional terms are considered "further restrictions"
+within the meaning of section 10. If the Program as you received it, or any
+part of it, contains a notice stating that it is governed by this License
+along with a term that is a further restriction, you may remove that term.
+If a license document contains a further restriction but permits relicensing
+or conveying under this License, you may add to a covered work material governed
+by the terms of that license document, provided that the further restriction
+does not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you must place,
+in the relevant source files, a statement of the additional terms that apply
+to those files, or a notice indicating where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the form
+of a separately written license, or stated as exceptions; the above requirements
+apply either way.
+
+   8. Termination.
+
+You may not propagate or modify a covered work except as expressly provided
+under this License. Any attempt otherwise to propagate or modify it is void,
+and will automatically terminate your rights under this License (including
+any patent licenses granted under the third paragraph of section 11).
+
+However, if you cease all violation of this License, then your license from
+a particular copyright holder is reinstated (a) provisionally, unless and
+until the copyright holder explicitly and finally terminates your license,
+and (b) permanently, if the copyright holder fails to notify you of the violation
+by some reasonable means prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is reinstated permanently
+if the copyright holder notifies you of the violation by some reasonable means,
+this is the first time you have received notice of violation of this License
+(for any work) from that copyright holder, and you cure the violation prior
+to 30 days after your receipt of the notice.
+
+Termination of your rights under this section does not terminate the licenses
+of parties who have received copies or rights from you under this License.
+If your rights have been terminated and not permanently reinstated, you do
+not qualify to receive new licenses for the same material under section 10.
+
+   9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run a copy
+of the Program. Ancillary propagation of a covered work occurring solely as
+a consequence of using peer-to-peer transmission to receive a copy likewise
+does not require acceptance. However, nothing other than this License grants
+you permission to propagate or modify any covered work. These actions infringe
+copyright if you do not accept this License. Therefore, by modifying or propagating
+a covered work, you indicate your acceptance of this License to do so.
+
+   10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically receives
+a license from the original licensors, to run, modify and propagate that work,
+subject to this License. You are not responsible for enforcing compliance
+by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an organization,
+or substantially all assets of one, or subdividing an organization, or merging
+organizations. If propagation of a covered work results from an entity transaction,
+each party to that transaction who receives a copy of the work also receives
+whatever licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the Corresponding
+Source of the work from the predecessor in interest, if the predecessor has
+it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the rights
+granted or affirmed under this License. For example, you may not impose a
+license fee, royalty, or other charge for exercise of rights granted under
+this License, and you may not initiate litigation (including a cross-claim
+or counterclaim in a lawsuit) alleging that any patent claim is infringed
+by making, using, selling, offering for sale, or importing the Program or
+any portion of it.
+
+   11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this License
+of the Program or a work on which the Program is based. The work thus licensed
+is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims owned or controlled
+by the contributor, whether already acquired or hereafter acquired, that would
+be infringed by some manner, permitted by this License, of making, using,
+or selling its contributor version, but do not include claims that would be
+infringed only as a consequence of further modification of the contributor
+version. For purposes of this definition, "control" includes the right to
+grant patent sublicenses in a manner consistent with the requirements of this
+License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free patent
+license under the contributor's essential patent claims, to make, use, sell,
+offer for sale, import and otherwise run, modify and propagate the contents
+of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express agreement
+or commitment, however denominated, not to enforce a patent (such as an express
+permission to practice a patent or covenant not to sue for patent infringement).
+To "grant" such a patent license to a party means to make such an agreement
+or commitment not to enforce a patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license, and the
+Corresponding Source of the work is not available for anyone to copy, free
+of charge and under the terms of this License, through a publicly available
+network server or other readily accessible means, then you must either (1)
+cause the Corresponding Source to be so available, or (2) arrange to deprive
+yourself of the benefit of the patent license for this particular work, or
+(3) arrange, in a manner consistent with the requirements of this License,
+to extend the patent license to downstream recipients. "Knowingly relying"
+means you have actual knowledge that, but for the patent license, your conveying
+the covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that country
+that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or arrangement,
+you convey, or propagate by procuring conveyance of, a covered work, and grant
+a patent license to some of the parties receiving the covered work authorizing
+them to use, propagate, modify or convey a specific copy of the covered work,
+then the patent license you grant is automatically extended to all recipients
+of the covered work and works based on it.
+
+A patent license is "discriminatory" if it does not include within the scope
+of its coverage, prohibits the exercise of, or is conditioned on the non-exercise
+of one or more of the rights that are specifically granted under this License.
+You may not convey a covered work if you are a party to an arrangement with
+a third party that is in the business of distributing software, under which
+you make payment to the third party based on the extent of your activity of
+conveying the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by you
+(or copies made from those copies), or (b) primarily for and in connection
+with specific products or compilations that contain the covered work, unless
+you entered into that arrangement, or that patent license was granted, prior
+to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting any implied
+license or other defenses to infringement that may otherwise be available
+to you under applicable patent law.
+
+   12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or otherwise)
+that contradict the conditions of this License, they do not excuse you from
+the conditions of this License. If you cannot convey a covered work so as
+to satisfy simultaneously your obligations under this License and any other
+pertinent obligations, then as a consequence you may not convey it at all.
+For example, if you agree to terms that obligate you to collect a royalty
+for further conveying from those to whom you convey the Program, the only
+way you could satisfy both those terms and this License would be to refrain
+entirely from conveying the Program.
+
+   13. Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have permission to
+link or combine any covered work with a work licensed under version 3 of the
+GNU Affero General Public License into a single combined work, and to convey
+the resulting work. The terms of this License will continue to apply to the
+part which is the covered work, but the special requirements of the GNU Affero
+General Public License, section 13, concerning interaction through a network
+will apply to the combination as such.
+
+   14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions of the
+GNU General Public License from time to time. Such new versions will be similar
+in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies
+that a certain numbered version of the GNU General Public License "or any
+later version" applies to it, you have the option of following the terms and
+conditions either of that numbered version or of any later version published
+by the Free Software Foundation. If the Program does not specify a version
+number of the GNU General Public License, you may choose any version ever
+published by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions of
+the GNU General Public License can be used, that proxy's public statement
+of acceptance of a version permanently authorizes you to choose that version
+for the Program.
+
+Later license versions may give you additional or different permissions. However,
+no additional obligations are imposed on any author or copyright holder as
+a result of your choosing to follow a later version.
+
+   15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
+LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
+OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
+PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+   16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
+ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM
+AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
+USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
+PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+   17. Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided above cannot
+be given local legal effect according to their terms, reviewing courts shall
+apply local law that most closely approximates an absolute waiver of all civil
+liability in connection with the Program, unless a warranty or assumption
+of liability accompanies a copy of the Program in return for a fee. END OF
+TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible
+use to the public, the best way to achieve this is to make it free software
+which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach
+them to the start of each source file to most effectively state the exclusion
+of warranty; and each file should have at least the "copyright" line and a
+pointer to where the full notice is found.
+
+<one line to give the program's name and a brief idea of what it does.>
+
+Copyright (C) <year> <name of author>

+GNU GENERAL PUBLIC LICENSE
+
+Version 3, 29 June 2007
+
+Copyright © 2007 Free Software Foundation, Inc. <http s ://fsf.org/>
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The GNU General Public License is a free, copyleft license for software and
+other kinds of works.
+
+The licenses for most software and other practical works are designed to take
+away your freedom to share and change the works. By contrast, the GNU General
+Public License is intended to guarantee your freedom to share and change all
+versions of a program--to make sure it remains free software for all its users.
+We, the Free Software Foundation, use the GNU General Public License for most
+of our software; it applies also to any other work released this way by its
+authors. You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for them if you wish), that
+you receive source code or can get it if you want it, that you can change
+the software or use pieces of it in new free programs, and that you know you
+can do these things.
+
+To protect your rights, we need to prevent others from denying you these rights
+or asking you to surrender the rights. Therefore, you have certain responsibilities
+if you distribute copies of the software, or if you modify it: responsibilities
+to respect the freedom of others.
+
+For example, if you distribute copies of such a program, whether gratis or
+for a fee, you must pass on to the recipients the same freedoms that you received.
+You must make sure that they, too, receive or can get the source code. And
+you must show them these terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps: (1) assert
+copyright on the software, and (2) offer you this License giving you legal
+permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains that
+there is no warranty for this free software. For both users' and authors'
+sake, the GPL requires that modified versions be marked as changed, so that
+their problems will not be attributed erroneously to authors of previous versions.
+
+Some devices are designed to deny users access to install or run modified
+versions of the software inside them, although the manufacturer can do so.
+This is fundamentally incompatible with the aim of protecting users' freedom
+to change the software. The systematic pattern of such abuse occurs in the
+area of products for individuals to use, which is precisely where it is most
+unacceptable. Therefore, we have designed this version of the GPL to prohibit
+the practice for those products. If such problems arise substantially in other
+domains, we stand ready to extend this provision to those domains in future
+versions of the GPL, as needed to protect the freedom of users.
+
+Finally, every program is threatened constantly by software patents. States
+should not allow patents to restrict development and use of software on general-purpose
+computers, but in those that do, we wish to avoid the special danger that
+patents applied to a free program could make it effectively proprietary. To
+prevent this, the GPL assures that patents cannot be used to render the program
+non-free.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+TERMS AND CONDITIONS
+
+   0. Definitions.
+
+   "This License" refers to version 3 of the GNU General Public License.
+
+"Copyright" also means copyright-like laws that apply to other kinds of works,
+such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this License.
+Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals
+or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work in
+a fashion requiring copyright permission, other than the making of an exact
+copy. The resulting work is called a "modified version" of the earlier work
+or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based on the
+Program.
+
+To "propagate" a work means to do anything with it that, without permission,
+would make you directly or secondarily liable for infringement under applicable
+copyright law, except executing it on a computer or modifying a private copy.
+Propagation includes copying, distribution (with or without modification),
+making available to the public, and in some countries other activities as
+well.
+
+To "convey" a work means any kind of propagation that enables other parties
+to make or receive copies. Mere interaction with a user through a computer
+network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays "Appropriate Legal Notices" to the
+extent that it includes a convenient and prominently visible feature that
+(1) displays an appropriate copyright notice, and (2) tells the user that
+there is no warranty for the work (except to the extent that warranties are
+provided), that licensees may convey the work under this License, and how
+to view a copy of this License. If the interface presents a list of user commands
+or options, such as a menu, a prominent item in the list meets this criterion.
+
+   1. Source Code.
+
+The "source code" for a work means the preferred form of the work for making
+modifications to it. "Object code" means any non-source form of a work.
+
+A "Standard Interface" means an interface that either is an official standard
+defined by a recognized standards body, or, in the case of interfaces specified
+for a particular programming language, one that is widely used among developers
+working in that language.
+
+The "System Libraries" of an executable work include anything, other than
+the work as a whole, that (a) is included in the normal form of packaging
+a Major Component, but which is not part of that Major Component, and (b)
+serves only to enable use of the work with that Major Component, or to implement
+a Standard Interface for which an implementation is available to the public
+in source code form. A "Major Component", in this context, means a major essential
+component (kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to produce
+the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all the source
+code needed to generate, install, and (for an executable work) run the object
+code and to modify the work, including scripts to control those activities.
+However, it does not include the work's System Libraries, or general-purpose
+tools or generally available free programs which are used unmodified in performing
+those activities but which are not part of the work. For example, Corresponding
+Source includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically linked
+subprograms that the work is specifically designed to require, such as by
+intimate data communication or control flow between those subprograms and
+other parts of the work.
+
+The Corresponding Source need not include anything that users can regenerate
+automatically from other parts of the Corresponding Source.
+
+   The Corresponding Source for a work in source code form is that same work.
+
+   2. Basic Permissions.
+
+All rights granted under this License are granted for the term of copyright
+on the Program, and are irrevocable provided the stated conditions are met.
+This License explicitly affirms your unlimited permission to run the unmodified
+Program. The output from running a covered work is covered by this License
+only if the output, given its content, constitutes a covered work. This License
+acknowledges your rights of fair use or other equivalent, as provided by copyright
+law.
+
+You may make, run and propagate covered works that you do not convey, without
+conditions so long as your license otherwise remains in force. You may convey
+covered works to others for the sole purpose of having them make modifications
+exclusively for you, or provide you with facilities for running those works,
+provided that you comply with the terms of this License in conveying all material
+for which you do not control copyright. Those thus making or running the covered
+works for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of your copyrighted
+material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the conditions
+stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
+
+   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological measure
+under any applicable law fulfilling obligations under article 11 of the WIPO
+copyright treaty adopted on 20 December 1996, or similar laws prohibiting
+or restricting circumvention of such measures.
+
+When you convey a covered work, you waive any legal power to forbid circumvention
+of technological measures to the extent such circumvention is effected by
+exercising rights under this License with respect to the covered work, and
+you disclaim any intention to limit operation or modification of the work
+as a means of enforcing, against the work's users, your or third parties'
+legal rights to forbid circumvention of technological measures.
+
+   4. Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you receive
+it, in any medium, provided that you conspicuously and appropriately publish
+on each copy an appropriate copyright notice; keep intact all notices stating
+that this License and any non-permissive terms added in accord with section
+7 apply to the code; keep intact all notices of the absence of any warranty;
+and give all recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey, and you
+may offer support or warranty protection for a fee.
+
+   5. Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to produce
+it from the Program, in the form of source code under the terms of section
+4, provided that you also meet all of these conditions:
+
+a) The work must carry prominent notices stating that you modified it, and
+giving a relevant date.
+
+b) The work must carry prominent notices stating that it is released under
+this License and any conditions added under section 7. This requirement modifies
+the requirement in section 4 to "keep intact all notices".
+
+c) You must license the entire work, as a whole, under this License to anyone
+who comes into possession of a copy. This License will therefore apply, along
+with any applicable section 7 additional terms, to the whole of the work,
+and all its parts, regardless of how they are packaged. This License gives
+no permission to license the work in any other way, but it does not invalidate
+such permission if you have separately received it.
+
+d) If the work has interactive user interfaces, each must display Appropriate
+Legal Notices; however, if the Program has interactive interfaces that do
+not display Appropriate Legal Notices, your work need not make them do so.
+
+A compilation of a covered work with other separate and independent works,
+which are not by their nature extensions of the covered work, and which are
+not combined with it such as to form a larger program, in or on a volume of
+a storage or distribution medium, is called an "aggregate" if the compilation
+and its resulting copyright are not used to limit the access or legal rights
+of the compilation's users beyond what the individual works permit. Inclusion
+of a covered work in an aggregate does not cause this License to apply to
+the other parts of the aggregate.
+
+   6. Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of sections
+4 and 5, provided that you also convey the machine-readable Corresponding
+Source under the terms of this License, in one of these ways:
+
+a) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by the Corresponding Source fixed
+on a durable physical medium customarily used for software interchange.
+
+b) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by a written offer, valid for
+at least three years and valid for as long as you offer spare parts or customer
+support for that product model, to give anyone who possesses the object code
+either (1) a copy of the Corresponding Source for all the software in the
+product that is covered by this License, on a durable physical medium customarily
+used for software interchange, for a price no more than your reasonable cost
+of physically performing this conveying of source, or (2) access to copy the
+Corresponding Source from a network server at no charge.
+
+c) Convey individual copies of the object code with a copy of the written
+offer to provide the Corresponding Source. This alternative is allowed only
+occasionally and noncommercially, and only if you received the object code
+with such an offer, in accord with subsection 6b.
+
+d) Convey the object code by offering access from a designated place (gratis
+or for a charge), and offer equivalent access to the Corresponding Source
+in the same way through the same place at no further charge. You need not
+require recipients to copy the Corresponding Source along with the object
+code. If the place to copy the object code is a network server, the Corresponding
+Source may be on a different server (operated by you or a third party) that
+supports equivalent copying facilities, provided you maintain clear directions
+next to the object code saying where to find the Corresponding Source. Regardless
+of what server hosts the Corresponding Source, you remain obligated to ensure
+that it is available for as long as needed to satisfy these requirements.
+
+e) Convey the object code using peer-to-peer transmission, provided you inform
+other peers where the object code and Corresponding Source of the work are
+being offered to the general public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded from
+the Corresponding Source as a System Library, need not be included in conveying
+the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any tangible
+personal property which is normally used for personal, family, or household
+purposes, or (2) anything designed or sold for incorporation into a dwelling.
+In determining whether a product is a consumer product, doubtful cases shall
+be resolved in favor of coverage. For a particular product received by a particular
+user, "normally used" refers to a typical or common use of that class of product,
+regardless of the status of the particular user or of the way in which the
+particular user actually uses, or expects or is expected to use, the product.
+A product is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent the
+only significant mode of use of the product.
+
+"Installation Information" for a User Product means any methods, procedures,
+authorization keys, or other information required to install and execute modified
+versions of a covered work in that User Product from a modified version of
+its Corresponding Source. The information must suffice to ensure that the
+continued functioning of the modified object code is in no case prevented
+or interfered with solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or specifically
+for use in, a User Product, and the conveying occurs as part of a transaction
+in which the right of possession and use of the User Product is transferred
+to the recipient in perpetuity or for a fixed term (regardless of how the
+transaction is characterized), the Corresponding Source conveyed under this
+section must be accompanied by the Installation Information. But this requirement
+does not apply if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has been installed
+in ROM).
+
+The requirement to provide Installation Information does not include a requirement
+to continue to provide support service, warranty, or updates for a work that
+has been modified or installed by the recipient, or for the User Product in
+which it has been modified or installed. Access to a network may be denied
+when the modification itself materially and adversely affects the operation
+of the network or violates the rules and protocols for communication across
+the network.
+
+Corresponding Source conveyed, and Installation Information provided, in accord
+with this section must be in a format that is publicly documented (and with
+an implementation available to the public in source code form), and must require
+no special password or key for unpacking, reading or copying.
+
+   7. Additional Terms.
+
+"Additional permissions" are terms that supplement the terms of this License
+by making exceptions from one or more of its conditions. Additional permissions
+that are applicable to the entire Program shall be treated as though they
+were included in this License, to the extent that they are valid under applicable
+law. If additional permissions apply only to part of the Program, that part
+may be used separately under those permissions, but the entire Program remains
+governed by this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option remove any
+additional permissions from that copy, or from any part of it. (Additional
+permissions may be written to require their own removal in certain cases when
+you modify the work.) You may place additional permissions on material, added
+by you to a covered work, for which you have or can give appropriate copyright
+permission.
+
+Notwithstanding any other provision of this License, for material you add
+to a covered work, you may (if authorized by the copyright holders of that
+material) supplement the terms of this License with terms:
+
+a) Disclaiming warranty or limiting liability differently from the terms of
+sections 15 and 16 of this License; or
+
+b) Requiring preservation of specified reasonable legal notices or author
+attributions in that material or in the Appropriate Legal Notices displayed
+by works containing it; or
+
+c) Prohibiting misrepresentation of the origin of that material, or requiring
+that modified versions of such material be marked in reasonable ways as different
+from the original version; or
+
+d) Limiting the use for publicity purposes of names of licensors or authors
+of the material; or
+
+e) Declining to grant rights under trademark law for use of some trade names,
+trademarks, or service marks; or
+
+f) Requiring indemnification of licensors and authors of that material by
+anyone who conveys the material (or modified versions of it) with contractual
+assumptions of liability to the recipient, for any liability that these contractual
+assumptions directly impose on those licensors and authors.
+
+All other non-permissive additional terms are considered "further restrictions"
+within the meaning of section 10. If the Program as you received it, or any
+part of it, contains a notice stating that it is governed by this License
+along with a term that is a further restriction, you may remove that term.
+If a license document contains a further restriction but permits relicensing
+or conveying under this License, you may add to a covered work material governed
+by the terms of that license document, provided that the further restriction
+does not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you must place,
+in the relevant source files, a statement of the additional terms that apply
+to those files, or a notice indicating where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the form
+of a separately written license, or stated as exceptions; the above requirements
+apply either way.
+
+   8. Termination.
+
+You may not propagate or modify a covered work except as expressly provided
+under this License. Any attempt otherwise to propagate or modify it is void,
+and will automatically terminate your rights under this License (including
+any patent licenses granted under the third paragraph of section 11).
+
+However, if you cease all violation of this License, then your license from
+a particular copyright holder is reinstated (a) provisionally, unless and
+until the copyright holder explicitly and finally terminates your license,
+and (b) permanently, if the copyright holder fails to notify you of the violation
+by some reasonable means prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is reinstated permanently
+if the copyright holder notifies you of the violation by some reasonable means,
+this is the first time you have received notice of violation of this License
+(for any work) from that copyright holder, and you cure the violation prior
+to 30 days after your receipt of the notice.
+
+Termination of your rights under this section does not terminate the licenses
+of parties who have received copies or rights from you under this License.
+If your rights have been terminated and not permanently reinstated, you do
+not qualify to receive new licenses for the same material under section 10.
+
+   9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run a copy
+of the Program. Ancillary propagation of a covered work occurring solely as
+a consequence of using peer-to-peer transmission to receive a copy likewise
+does not require acceptance. However, nothing other than this License grants
+you permission to propagate or modify any covered work. These actions infringe
+copyright if you do not accept this License. Therefore, by modifying or propagating
+a covered work, you indicate your acceptance of this License to do so.
+
+   10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically receives
+a license from the original licensors, to run, modify and propagate that work,
+subject to this License. You are not responsible for enforcing compliance
+by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an organization,
+or substantially all assets of one, or subdividing an organization, or merging
+organizations. If propagation of a covered work results from an entity transaction,
+each party to that transaction who receives a copy of the work also receives
+whatever licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the Corresponding
+Source of the work from the predecessor in interest, if the predecessor has
+it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the rights
+granted or affirmed under this License. For example, you may not impose a
+license fee, royalty, or other charge for exercise of rights granted under
+this License, and you may not initiate litigation (including a cross-claim
+or counterclaim in a lawsuit) alleging that any patent claim is infringed
+by making, using, selling, offering for sale, or importing the Program or
+any portion of it.
+
+   11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this License
+of the Program or a work on which the Program is based. The work thus licensed
+is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims owned or controlled
+by the contributor, whether already acquired or hereafter acquired, that would
+be infringed by some manner, permitted by this License, of making, using,
+or selling its contributor version, but do not include claims that would be
+infringed only as a consequence of further modification of the contributor
+version. For purposes of this definition, "control" includes the right to
+grant patent sublicenses in a manner consistent with the requirements of this
+License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free patent
+license under the contributor's essential patent claims, to make, use, sell,
+offer for sale, import and otherwise run, modify and propagate the contents
+of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express agreement
+or commitment, however denominated, not to enforce a patent (such as an express
+permission to practice a patent or covenant not to sue for patent infringement).
+To "grant" such a patent license to a party means to make such an agreement
+or commitment not to enforce a patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license, and the
+Corresponding Source of the work is not available for anyone to copy, free
+of charge and under the terms of this License, through a publicly available
+network server or other readily accessible means, then you must either (1)
+cause the Corresponding Source to be so available, or (2) arrange to deprive
+yourself of the benefit of the patent license for this particular work, or
+(3) arrange, in a manner consistent with the requirements of this License,
+to extend the patent license to downstream recipients. "Knowingly relying"
+means you have actual knowledge that, but for the patent license, your conveying
+the covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that country
+that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or arrangement,
+you convey, or propagate by procuring conveyance of, a covered work, and grant
+a patent license to some of the parties receiving the covered work authorizing
+them to use, propagate, modify or convey a specific copy of the covered work,
+then the patent license you grant is automatically extended to all recipients
+of the covered work and works based on it.
+
+A patent license is "discriminatory" if it does not include within the scope
+of its coverage, prohibits the exercise of, or is conditioned on the non-exercise
+of one or more of the rights that are specifically granted under this License.
+You may not convey a covered work if you are a party to an arrangement with
+a third party that is in the business of distributing software, under which
+you make payment to the third party based on the extent of your activity of
+conveying the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by you
+(or copies made from those copies), or (b) primarily for and in connection
+with specific products or compilations that contain the covered work, unless
+you entered into that arrangement, or that patent license was granted, prior
+to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting any implied
+license or other defenses to infringement that may otherwise be available
+to you under applicable patent law.
+
+   12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or otherwise)
+that contradict the conditions of this License, they do not excuse you from
+the conditions of this License. If you cannot convey a covered work so as
+to satisfy simultaneously your obligations under this License and any other
+pertinent obligations, then as a consequence you may not convey it at all.
+For example, if you agree to terms that obligate you to collect a royalty
+for further conveying from those to whom you convey the Program, the only
+way you could satisfy both those terms and this License would be to refrain
+entirely from conveying the Program.
+
+   13. Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have permission to
+link or combine any covered work with a work licensed under version 3 of the
+GNU Affero General Public License into a single combined work, and to convey
+the resulting work. The terms of this License will continue to apply to the
+part which is the covered work, but the special requirements of the GNU Affero
+General Public License, section 13, concerning interaction through a network
+will apply to the combination as such.
+
+   14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions of the
+GNU General Public License from time to time. Such new versions will be similar
+in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies
+that a certain numbered version of the GNU General Public License "or any
+later version" applies to it, you have the option of following the terms and
+conditions either of that numbered version or of any later version published
+by the Free Software Foundation. If the Program does not specify a version
+number of the GNU General Public License, you may choose any version ever
+published by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions of
+the GNU General Public License can be used, that proxy's public statement
+of acceptance of a version permanently authorizes you to choose that version
+for the Program.
+
+Later license versions may give you additional or different permissions. However,
+no additional obligations are imposed on any author or copyright holder as
+a result of your choosing to follow a later version.
+
+   15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
+LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
+OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
+PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+   16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
+ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM
+AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
+USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
+PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+   17. Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided above cannot
+be given local legal effect according to their terms, reviewing courts shall
+apply local law that most closely approximates an absolute waiver of all civil
+liability in connection with the Program, unless a warranty or assumption
+of liability accompanies a copy of the Program in return for a fee. END OF
+TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible
+use to the public, the best way to achieve this is to make it free software
+which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach
+them to the start of each source file to most effectively state the exclusion
+of warranty; and each file should have at least the "copyright" line and a
+pointer to where the full notice is found.
+
+<one line to give the program's name and a brief idea of what it does.>
+
+Copyright (C) <year> <name of author>
+
+This program is free software: you can redistribute it and/or modify it under
+the terms of the GNU General Public License as published by the Free Software
+Foundation, either version 3 of the License, or (at your option) any later
+version.
+
+This program is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
+FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
+
+You should have received a copy of the GNU General Public License along with
+this program. If not, see <http s ://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program does terminal interaction, make it output a short notice like
+this when it starts in an interactive mode:
+
+<program> Copyright (C) <year> <name of author>
+
+This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+
+This is free software, and you are welcome to redistribute it under certain
+conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands might
+be different; for a GUI interface, you would use an "about box".
+
+You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary. For
+more information on this, and how to apply and follow the GNU GPL, see <http
+s ://www.gnu.org/licenses/>.
+
+The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General Public
+License instead of this License. But first, please read <http s ://www.gnu.org/
+licenses /why-not-lgpl.html>.

+GNU GENERAL PUBLIC LICENSE
+
+Version 3, 29 June 2007
+
+Copyright © 2007 Free Software Foundation, Inc. <http s ://fsf.org/>
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The GNU General Public License is a free, copyleft license for software and
+other kinds of works.
+
+The licenses for most software and other practical works are designed to take
+away your freedom to share and change the works. By contrast, the GNU General
+Public License is intended to guarantee your freedom to share and change all
+versions of a program--to make sure it remains free software for all its users.
+We, the Free Software Foundation, use the GNU General Public License for most
+of our software; it applies also to any other work released this way by its
+authors. You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for them if you wish), that
+you receive source code or can get it if you want it, that you can change
+the software or use pieces of it in new free programs, and that you know you
+can do these things.
+
+To protect your rights, we need to prevent others from denying you these rights
+or asking you to surrender the rights. Therefore, you have certain responsibilities
+if you distribute copies of the software, or if you modify it: responsibilities
+to respect the freedom of others.
+
+For example, if you distribute copies of such a program, whether gratis or
+for a fee, you must pass on to the recipients the same freedoms that you received.
+You must make sure that they, too, receive or can get the source code. And
+you must show them these terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps: (1) assert
+copyright on the software, and (2) offer you this License giving you legal
+permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains that
+there is no warranty for this free software. For both users' and authors'
+sake, the GPL requires that modified versions be marked as changed, so that
+their problems will not be attributed erroneously to authors of previous versions.
+
+Some devices are designed to deny users access to install or run modified
+versions of the software inside them, although the manufacturer can do so.
+This is fundamentally incompatible with the aim of protecting users' freedom
+to change the software. The systematic pattern of such abuse occurs in the
+area of products for individuals to use, which is precisely where it is most
+unacceptable. Therefore, we have designed this version of the GPL to prohibit
+the practice for those products. If such problems arise substantially in other
+domains, we stand ready to extend this provision to those domains in future
+versions of the GPL, as needed to protect the freedom of users.
+
+Finally, every program is threatened constantly by software patents. States
+should not allow patents to restrict development and use of software on general-purpose
+computers, but in those that do, we wish to avoid the special danger that
+patents applied to a free program could make it effectively proprietary. To
+prevent this, the GPL assures that patents cannot be used to render the program
+non-free.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+TERMS AND CONDITIONS
+
+   0. Definitions.
+
+   "This License" refers to version 3 of the GNU General Public License.
+
+"Copyright" also means copyright-like laws that apply to other kinds of works,
+such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this License.
+Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals
+or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work in
+a fashion requiring copyright permission, other than the making of an exact
+copy. The resulting work is called a "modified version" of the earlier work
+or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based on the
+Program.
+
+To "propagate" a work means to do anything with it that, without permission,
+would make you directly or secondarily liable for infringement under applicable
+copyright law, except executing it on a computer or modifying a private copy.
+Propagation includes copying, distribution (with or without modification),
+making available to the public, and in some countries other activities as
+well.
+
+To "convey" a work means any kind of propagation that enables other parties
+to make or receive copies. Mere interaction with a user through a computer
+network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays "Appropriate Legal Notices" to the
+extent that it includes a convenient and prominently visible feature that
+(1) displays an appropriate copyright notice, and (2) tells the user that
+there is no warranty for the work (except to the extent that warranties are
+provided), that licensees may convey the work under this License, and how
+to view a copy of this License. If the interface presents a list of user commands
+or options, such as a menu, a prominent item in the list meets this criterion.
+
+   1. Source Code.
+
+The "source code" for a work means the preferred form of the work for making
+modifications to it. "Object code" means any non-source form of a work.
+
+A "Standard Interface" means an interface that either is an official standard
+defined by a recognized standards body, or, in the case of interfaces specified
+for a particular programming language, one that is widely used among developers
+working in that language.
+
+The "System Libraries" of an executable work include anything, other than
+the work as a whole, that (a) is included in the normal form of packaging
+a Major Component, but which is not part of that Major Component, and (b)
+serves only to enable use of the work with that Major Component, or to implement
+a Standard Interface for which an implementation is available to the public
+in source code form. A "Major Component", in this context, means a major essential
+component (kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to produce
+the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all the source
+code needed to generate, install, and (for an executable work) run the object
+code and to modify the work, including scripts to control those activities.
+However, it does not include the work's System Libraries, or general-purpose
+tools or generally available free programs which are used unmodified in performing
+those activities but which are not part of the work. For example, Corresponding
+Source includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically linked
+subprograms that the work is specifically designed to require, such as by
+intimate data communication or control flow between those subprograms and
+other parts of the work.
+
+The Corresponding Source need not include anything that users can regenerate
+automatically from other parts of the Corresponding Source.
+
+   The Corresponding Source for a work in source code form is that same work.
+
+   2. Basic Permissions.
+
+All rights granted under this License are granted for the term of copyright
+on the Program, and are irrevocable provided the stated conditions are met.
+This License explicitly affirms your unlimited permission to run the unmodified
+Program. The output from running a covered work is covered by this License
+only if the output, given its content, constitutes a covered work. This License
+acknowledges your rights of fair use or other equivalent, as provided by copyright
+law.
+
+You may make, run and propagate covered works that you do not convey, without
+conditions so long as your license otherwise remains in force. You may convey
+covered works to others for the sole purpose of having them make modifications
+exclusively for you, or provide you with facilities for running those works,
+provided that you comply with the terms of this License in conveying all material
+for which you do not control copyright. Those thus making or running the covered
+works for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of your copyrighted
+material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the conditions
+stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
+
+   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological measure
+under any applicable law fulfilling obligations under article 11 of the WIPO
+copyright treaty adopted on 20 December 1996, or similar laws prohibiting
+or restricting circumvention of such measures.
+
+When you convey a covered work, you waive any legal power to forbid circumvention
+of technological measures to the extent such circumvention is effected by
+exercising rights under this License with respect to the covered work, and
+you disclaim any intention to limit operation or modification of the work
+as a means of enforcing, against the work's users, your or third parties'
+legal rights to forbid circumvention of technological measures.
+
+   4. Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you receive
+it, in any medium, provided that you conspicuously and appropriately publish
+on each copy an appropriate copyright notice; keep intact all notices stating
+that this License and any non-permissive terms added in accord with section
+7 apply to the code; keep intact all notices of the absence of any warranty;
+and give all recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey, and you
+may offer support or warranty protection for a fee.
+
+   5. Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to produce
+it from the Program, in the form of source code under the terms of section
+4, provided that you also meet all of these conditions:
+
+a) The work must carry prominent notices stating that you modified it, and
+giving a relevant date.
+
+b) The work must carry prominent notices stating that it is released under
+this License and any conditions added under section 7. This requirement modifies
+the requirement in section 4 to "keep intact all notices".
+
+c) You must license the entire work, as a whole, under this License to anyone
+who comes into possession of a copy. This License will therefore apply, along
+with any applicable section 7 additional terms, to the whole of the work,
+and all its parts, regardless of how they are packaged. This License gives
+no permission to license the work in any other way, but it does not invalidate
+such permission if you have separately received it.
+
+d) If the work has interactive user interfaces, each must display Appropriate
+Legal Notices; however, if the Program has interactive interfaces that do
+not display Appropriate Legal Notices, your work need not make them do so.
+
+A compilation of a covered work with other separate and independent works,
+which are not by their nature extensions of the covered work, and which are
+not combined with it such as to form a larger program, in or on a volume of
+a storage or distribution medium, is called an "aggregate" if the compilation
+and its resulting copyright are not used to limit the access or legal rights
+of the compilation's users beyond what the individual works permit. Inclusion
+of a covered work in an aggregate does not cause this License to apply to
+the other parts of the aggregate.
+
+   6. Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of sections
+4 and 5, provided that you also convey the machine-readable Corresponding
+Source under the terms of this License, in one of these ways:
+
+a) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by the Corresponding Source fixed
+on a durable physical medium customarily used for software interchange.
+
+b) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by a written offer, valid for
+at least three years and valid for as long as you offer spare parts or customer
+support for that product model, to give anyone who possesses the object code
+either (1) a copy of the Corresponding Source for all the software in the
+product that is covered by this License, on a durable physical medium customarily
+used for software interchange, for a price no more than your reasonable cost
+of physically performing this conveying of source, or (2) access to copy the
+Corresponding Source from a network server at no charge.
+
+c) Convey individual copies of the object code with a copy of the written
+offer to provide the Corresponding Source. This alternative is allowed only
+occasionally and noncommercially, and only if you received the object code
+with such an offer, in accord with subsection 6b.
+
+d) Convey the object code by offering access from a designated place (gratis
+or for a charge), and offer equivalent access to the Corresponding Source
+in the same way through the same place at no further charge. You need not
+require recipients to copy the Corresponding Source along with the object
+code. If the place to copy the object code is a network server, the Corresponding
+Source may be on a different server (operated by you or a third party) that
+supports equivalent copying facilities, provided you maintain clear directions
+next to the object code saying where to find the Corresponding Source. Regardless
+of what server hosts the Corresponding Source, you remain obligated to ensure
+that it is available for as long as needed to satisfy these requirements.
+
+e) Convey the object code using peer-to-peer transmission, provided you inform
+other peers where the object code and Corresponding Source of the work are
+being offered to the general public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded from
+the Corresponding Source as a System Library, need not be included in conveying
+the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any tangible
+personal property which is normally used for personal, family, or household
+purposes, or (2) anything designed or sold for incorporation into a dwelling.
+In determining whether a product is a consumer product, doubtful cases shall
+be resolved in favor of coverage. For a particular product received by a particular
+user, "normally used" refers to a typical or common use of that class of product,
+regardless of the status of the particular user or of the way in which the
+particular user actually uses, or expects or is expected to use, the product.
+A product is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent the
+only significant mode of use of the product.
+
+"Installation Information" for a User Product means any methods, procedures,
+authorization keys, or other information required to install and execute modified
+versions of a covered work in that User Product from a modified version of
+its Corresponding Source. The information must suffice to ensure that the
+continued functioning of the modified object code is in no case prevented
+or interfered with solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or specifically
+for use in, a User Product, and the conveying occurs as part of a transaction
+in which the right of possession and use of the User Product is transferred
+to the recipient in perpetuity or for a fixed term (regardless of how the
+transaction is characterized), the Corresponding Source conveyed under this
+section must be accompanied by the Installation Information. But this requirement
+does not apply if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has been installed
+in ROM).
+
+The requirement to provide Installation Information does not include a requirement
+to continue to provide support service, warranty, or updates for a work that
+has been modified or installed by the recipient, or for the User Product in
+which it has been modified or installed. Access to a network may be denied
+when the modification itself materially and adversely affects the operation
+of the network or violates the rules and protocols for communication across
+the network.
+
+Corresponding Source conveyed, and Installation Information provided, in accord
+with this section must be in a format that is publicly documented (and with
+an implementation available to the public in source code form), and must require
+no special password or key for unpacking, reading or copying.
+
+   7. Additional Terms.
+
+"Additional permissions" are terms that supplement the terms of this License
+by making exceptions from one or more of its conditions. Additional permissions
+that are applicable to the entire Program shall be treated as though they
+were included in this License, to the extent that they are valid under applicable
+law. If additional permissions apply only to part of the Program, that part
+may be used separately under those permissions, but the entire Program remains
+governed by this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option remove any
+additional permissions from that copy, or from any part of it. (Additional
+permissions may be written to require their own removal in certain cases when
+you modify the work.) You may place additional permissions on material, added
+by you to a covered work, for which you have or can give appropriate copyright
+permission.
+
+Notwithstanding any other provision of this License, for material you add
+to a covered work, you may (if authorized by the copyright holders of that
+material) supplement the terms of this License with terms:
+
+a) Disclaiming warranty or limiting liability differently from the terms of
+sections 15 and 16 of this License; or
+
+b) Requiring preservation of specified reasonable legal notices or author
+attributions in that material or in the Appropriate Legal Notices displayed
+by works containing it; or
+
+c) Prohibiting misrepresentation of the origin of that material, or requiring
+that modified versions of such material be marked in reasonable ways as different
+from the original version; or
+
+d) Limiting the use for publicity purposes of names of licensors or authors
+of the material; or
+
+e) Declining to grant rights under trademark law for use of some trade names,
+trademarks, or service marks; or
+
+f) Requiring indemnification of licensors and authors of that material by
+anyone who conveys the material (or modified versions of it) with contractual
+assumptions of liability to the recipient, for any liability that these contractual
+assumptions directly impose on those licensors and authors.
+
+All other non-permissive additional terms are considered "further restrictions"
+within the meaning of section 10. If the Program as you received it, or any
+part of it, contains a notice stating that it is governed by this License
+along with a term that is a further restriction, you may remove that term.
+If a license document contains a further restriction but permits relicensing
+or conveying under this License, you may add to a covered work material governed
+by the terms of that license document, provided that the further restriction
+does not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you must place,
+in the relevant source files, a statement of the additional terms that apply
+to those files, or a notice indicating where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the form
+of a separately written license, or stated as exceptions; the above requirements
+apply either way.
+
+   8. Termination.
+
+You may not propagate or modify a covered work except as expressly provided
+under this License. Any attempt otherwise to propagate or modify it is void,
+and will automatically terminate your rights under this License (including
+any patent licenses granted under the third paragraph of section 11).
+
+However, if you cease all violation of this License, then your license from
+a particular copyright holder is reinstated (a) provisionally, unless and
+until the copyright holder explicitly and finally terminates your license,
+and (b) permanently, if the copyright holder fails to notify you of the violation
+by some reasonable means prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is reinstated permanently
+if the copyright holder notifies you of the violation by some reasonable means,
+this is the first time you have received notice of violation of this License
+(for any work) from that copyright holder, and you cure the violation prior
+to 30 days after your receipt of the notice.
+
+Termination of your rights under this section does not terminate the licenses
+of parties who have received copies or rights from you under this License.
+If your rights have been terminated and not permanently reinstated, you do
+not qualify to receive new licenses for the same material under section 10.
+
+   9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run a copy
+of the Program. Ancillary propagation of a covered work occurring solely as
+a consequence of using peer-to-peer transmission to receive a copy likewise
+does not require acceptance. However, nothing other than this License grants
+you permission to propagate or modify any covered work. These actions infringe
+copyright if you do not accept this License. Therefore, by modifying or propagating
+a covered work, you indicate your acceptance of this License to do so.
+
+   10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically receives
+a license from the original licensors, to run, modify and propagate that work,
+subject to this License. You are not responsible for enforcing compliance
+by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an organization,
+or substantially all assets of one, or subdividing an organization, or merging
+organizations. If propagation of a covered work results from an entity transaction,
+each party to that transaction who receives a copy of the work also receives
+whatever licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the Corresponding
+Source of the work from the predecessor in interest, if the predecessor has
+it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the rights
+granted or affirmed under this License. For example, you may not impose a
+license fee, royalty, or other charge for exercise of rights granted under
+this License, and you may not initiate litigation (including a cross-claim
+or counterclaim in a lawsuit) alleging that any patent claim is infringed
+by making, using, selling, offering for sale, or importing the Program or
+any portion of it.
+
+   11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this License
+of the Program or a work on which the Program is based. The work thus licensed
+is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims owned or controlled
+by the contributor, whether already acquired or hereafter acquired, that would
+be infringed by some manner, permitted by this License, of making, using,
+or selling its contributor version, but do not include claims that would be
+infringed only as a consequence of further modification of the contributor
+version. For purposes of this definition, "control" includes the right to
+grant patent sublicenses in a manner consistent with the requirements of this
+License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free patent
+license under the contributor's essential patent claims, to make, use, sell,
+offer for sale, import and otherwise run, modify and propagate the contents
+of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express agreement
+or commitment, however denominated, not to enforce a patent (such as an express
+permission to practice a patent or covenant not to sue for patent infringement).
+To "grant" such a patent license to a party means to make such an agreement
+or commitment not to enforce a patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license, and the
+Corresponding Source of the work is not available for anyone to copy, free
+of charge and under the terms of this License, through a publicly available
+network server or other readily accessible means, then you must either (1)
+cause the Corresponding Source to be so available, or (2) arrange to deprive
+yourself of the benefit of the patent license for this particular work, or
+(3) arrange, in a manner consistent with the requirements of this License,
+to extend the patent license to downstream recipients. "Knowingly relying"
+means you have actual knowledge that, but for the patent license, your conveying
+the covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that country
+that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or arrangement,
+you convey, or propagate by procuring conveyance of, a covered work, and grant
+a patent license to some of the parties receiving the covered work authorizing
+them to use, propagate, modify or convey a specific copy of the covered work,
+then the patent license you grant is automatically extended to all recipients
+of the covered work and works based on it.
+
+A patent license is "discriminatory" if it does not include within the scope
+of its coverage, prohibits the exercise of, or is conditioned on the non-exercise
+of one or more of the rights that are specifically granted under this License.
+You may not convey a covered work if you are a party to an arrangement with
+a third party that is in the business of distributing software, under which
+you make payment to the third party based on the extent of your activity of
+conveying the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by you
+(or copies made from those copies), or (b) primarily for and in connection
+with specific products or compilations that contain the covered work, unless
+you entered into that arrangement, or that patent license was granted, prior
+to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting any implied
+license or other defenses to infringement that may otherwise be available
+to you under applicable patent law.
+
+   12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or otherwise)
+that contradict the conditions of this License, they do not excuse you from
+the conditions of this License. If you cannot convey a covered work so as
+to satisfy simultaneously your obligations under this License and any other
+pertinent obligations, then as a consequence you may not convey it at all.
+For example, if you agree to terms that obligate you to collect a royalty
+for further conveying from those to whom you convey the Program, the only
+way you could satisfy both those terms and this License would be to refrain
+entirely from conveying the Program.
+
+   13. Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have permission to
+link or combine any covered work with a work licensed under version 3 of the
+GNU Affero General Public License into a single combined work, and to convey
+the resulting work. The terms of this License will continue to apply to the
+part which is the covered work, but the special requirements of the GNU Affero
+General Public License, section 13, concerning interaction through a network
+will apply to the combination as such.
+
+   14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions of the
+GNU General Public License from time to time. Such new versions will be similar
+in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies
+that a certain numbered version of the GNU General Public License "or any
+later version" applies to it, you have the option of following the terms and
+conditions either of that numbered version or of any later version published
+by the Free Software Foundation. If the Program does not specify a version
+number of the GNU General Public License, you may choose any version ever
+published by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions of
+the GNU General Public License can be used, that proxy's public statement
+of acceptance of a version permanently authorizes you to choose that version
+for the Program.
+
+Later license versions may give you additional or different permissions. However,
+no additional obligations are imposed on any author or copyright holder as
+a result of your choosing to follow a later version.
+
+   15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
+LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
+OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
+PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+   16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
+ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM
+AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
+USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
+PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+   17. Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided above cannot
+be given local legal effect according to their terms, reviewing courts shall
+apply local law that most closely approximates an absolute waiver of all civil
+liability in connection with the Program, unless a warranty or assumption
+of liability accompanies a copy of the Program in return for a fee. END OF
+TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible
+use to the public, the best way to achieve this is to make it free software
+which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach
+them to the start of each source file to most effectively state the exclusion
+of warranty; and each file should have at least the "copyright" line and a
+pointer to where the full notice is found.
+
+<one line to give the program's name and a brief idea of what it does.>
+
+Copyright (C) <year> <name of author>
+
+This program is free software: you can redistribute it and/or modify it under
+the terms of the GNU General Public License as published by the Free Software
+Foundation, either version 3 of the License, or (at your option) any later
+version.
+
+This program is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
+FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
+
+You should have received a copy of the GNU General Public License along with
+this program. If not, see <http s ://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program does terminal interaction, make it output a short notice like
+this when it starts in an interactive mode:
+
+<program> Copyright (C) <year> <name of author>
+
+This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+
+This is free software, and you are welcome to redistribute it under certain
+conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands might
+be different; for a GUI interface, you would use an "about box".
+
+You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary. For
+more information on this, and how to apply and follow the GNU GPL, see <http
+s ://www.gnu.org/licenses/>.
+
+The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General Public
+License instead of this License. But first, please read <http s ://www.gnu.org/
+licenses /why-not-lgpl.html>.

+GNU GENERAL PUBLIC LICENSE
+
+Version 3, 29 June 2007
+
+Copyright © 2007 Free Software Foundation, Inc. <http s ://fsf.org/>
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The GNU General Public License is a free, copyleft license for software and
+other kinds of works.
+
+The licenses for most software and other practical works are designed to take
+away your freedom to share and change the works. By contrast, the GNU General
+Public License is intended to guarantee your freedom to share and change all
+versions of a program--to make sure it remains free software for all its users.
+We, the Free Software Foundation, use the GNU General Public License for most
+of our software; it applies also to any other work released this way by its
+authors. You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for them if you wish), that
+you receive source code or can get it if you want it, that you can change
+the software or use pieces of it in new free programs, and that you know you
+can do these things.
+
+To protect your rights, we need to prevent others from denying you these rights
+or asking you to surrender the rights. Therefore, you have certain responsibilities
+if you distribute copies of the software, or if you modify it: responsibilities
+to respect the freedom of others.
+
+For example, if you distribute copies of such a program, whether gratis or
+for a fee, you must pass on to the recipients the same freedoms that you received.
+You must make sure that they, too, receive or can get the source code. And
+you must show them these terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps: (1) assert
+copyright on the software, and (2) offer you this License giving you legal
+permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains that
+there is no warranty for this free software. For both users' and authors'
+sake, the GPL requires that modified versions be marked as changed, so that
+their problems will not be attributed erroneously to authors of previous versions.
+
+Some devices are designed to deny users access to install or run modified
+versions of the software inside them, although the manufacturer can do so.
+This is fundamentally incompatible with the aim of protecting users' freedom
+to change the software. The systematic pattern of such abuse occurs in the
+area of products for individuals to use, which is precisely where it is most
+unacceptable. Therefore, we have designed this version of the GPL to prohibit
+the practice for those products. If such problems arise substantially in other
+domains, we stand ready to extend this provision to those domains in future
+versions of the GPL, as needed to protect the freedom of users.
+
+Finally, every program is threatened constantly by software patents. States
+should not allow patents to restrict development and use of software on general-purpose
+computers, but in those that do, we wish to avoid the special danger that
+patents applied to a free program could make it effectively proprietary. To
+prevent this, the GPL assures that patents cannot be used to render the program
+non-free.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+TERMS AND CONDITIONS
+
+   0. Definitions.
+
+   "This License" refers to version 3 of the GNU General Public License.
+
+"Copyright" also means copyright-like laws that apply to other kinds of works,
+such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this License.
+Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals
+or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work in
+a fashion requiring copyright permission, other than the making of an exact
+copy. The resulting work is called a "modified version" of the earlier work
+or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based on the
+Program.
+
+To "propagate" a work means to do anything with it that, without permission,
+would make you directly or secondarily liable for infringement under applicable
+copyright law, except executing it on a computer or modifying a private copy.
+Propagation includes copying, distribution (with or without modification),
+making available to the public, and in some countries other activities as
+well.
+
+To "convey" a work means any kind of propagation that enables other parties
+to make or receive copies. Mere interaction with a user through a computer
+network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays "Appropriate Legal Notices" to the
+extent that it includes a convenient and prominently visible feature that
+(1) displays an appropriate copyright notice, and (2) tells the user that
+there is no warranty for the work (except to the extent that warranties are
+provided), that licensees may convey the work under this License, and how
+to view a copy of this License. If the interface presents a list of user commands
+or options, such as a menu, a prominent item in the list meets this criterion.
+
+   1. Source Code.
+
+The "source code" for a work means the preferred form of the work for making
+modifications to it. "Object code" means any non-source form of a work.
+
+A "Standard Interface" means an interface that either is an official standard
+defined by a recognized standards body, or, in the case of interfaces specified
+for a particular programming language, one that is widely used among developers
+working in that language.
+
+The "System Libraries" of an executable work include anything, other than
+the work as a whole, that (a) is included in the normal form of packaging
+a Major Component, but which is not part of that Major Component, and (b)
+serves only to enable use of the work with that Major Component, or to implement
+a Standard Interface for which an implementation is available to the public
+in source code form. A "Major Component", in this context, means a major essential
+component (kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to produce
+the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all the source
+code needed to generate, install, and (for an executable work) run the object
+code and to modify the work, including scripts to control those activities.
+However, it does not include the work's System Libraries, or general-purpose
+tools or generally available free programs which are used unmodified in performing
+those activities but which are not part of the work. For example, Corresponding
+Source includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically linked
+subprograms that the work is specifically designed to require, such as by
+intimate data communication or control flow between those subprograms and
+other parts of the work.
+
+The Corresponding Source need not include anything that users can regenerate
+automatically from other parts of the Corresponding Source.
+
+   The Corresponding Source for a work in source code form is that same work.
+
+   2. Basic Permissions.
+
+All rights granted under this License are granted for the term of copyright
+on the Program, and are irrevocable provided the stated conditions are met.
+This License explicitly affirms your unlimited permission to run the unmodified
+Program. The output from running a covered work is covered by this License
+only if the output, given its content, constitutes a covered work. This License
+acknowledges your rights of fair use or other equivalent, as provided by copyright
+law.
+
+You may make, run and propagate covered works that you do not convey, without
+conditions so long as your license otherwise remains in force. You may convey
+covered works to others for the sole purpose of having them make modifications
+exclusively for you, or provide you with facilities for running those works,
+provided that you comply with the terms of this License in conveying all material
+for which you do not control copyright. Those thus making or running the covered
+works for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of your copyrighted
+material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the conditions
+stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
+
+   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological measure
+under any applicable law fulfilling obligations under article 11 of the WIPO
+copyright treaty adopted on 20 December 1996, or similar laws prohibiting
+or restricting circumvention of such measures.
+
+When you convey a covered work, you waive any legal power to forbid circumvention
+of technological measures to the extent such circumvention is effected by
+exercising rights under this License with respect to the covered work, and
+you disclaim any intention to limit operation or modification of the work
+as a means of enforcing, against the work's users, your or third parties'
+legal rights to forbid circumvention of technological measures.
+
+   4. Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you receive
+it, in any medium, provided that you conspicuously and appropriately publish
+on each copy an appropriate copyright notice; keep intact all notices stating
+that this License and any non-permissive terms added in accord with section
+7 apply to the code; keep intact all notices of the absence of any warranty;
+and give all recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey, and you
+may offer support or warranty protection for a fee.
+
+   5. Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to produce
+it from the Program, in the form of source code under the terms of section
+4, provided that you also meet all of these conditions:
+
+a) The work must carry prominent notices stating that you modified it, and
+giving a relevant date.
+
+b) The work must carry prominent notices stating that it is released under
+this License and any conditions added under section 7. This requirement modifies
+the requirement in section 4 to "keep intact all notices".
+
+c) You must license the entire work, as a whole, under this License to anyone
+who comes into possession of a copy. This License will therefore apply, along
+with any applicable section 7 additional terms, to the whole of the work,
+and all its parts, regardless of how they are packaged. This License gives
+no permission to license the work in any other way, but it does not invalidate
+such permission if you have separately received it.
+
+d) If the work has interactive user interfaces, each must display Appropriate
+Legal Notices; however, if the Program has interactive interfaces that do
+not display Appropriate Legal Notices, your work need not make them do so.
+
+A compilation of a covered work with other separate and independent works,
+which are not by their nature extensions of the covered work, and which are
+not combined with it such as to form a larger program, in or on a volume of
+a storage or distribution medium, is called an "aggregate" if the compilation
+and its resulting copyright are not used to limit the access or legal rights
+of the compilation's users beyond what the individual works permit. Inclusion
+of a covered work in an aggregate does not cause this License to apply to
+the other parts of the aggregate.
+
+   6. Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of sections
+4 and 5, provided that you also convey the machine-readable Corresponding
+Source under the terms of this License, in one of these ways:
+
+a) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by the Corresponding Source fixed
+on a durable physical medium customarily used for software interchange.
+
+b) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by a written offer, valid for
+at least three years and valid for as long as you offer spare parts or customer
+support for that product model, to give anyone who possesses the object code
+either (1) a copy of the Corresponding Source for all the software in the
+product that is covered by this License, on a durable physical medium customarily
+used for software interchange, for a price no more than your reasonable cost
+of physically performing this conveying of source, or (2) access to copy the
+Corresponding Source from a network server at no charge.
+
+c) Convey individual copies of the object code with a copy of the written
+offer to provide the Corresponding Source. This alternative is allowed only
+occasionally and noncommercially, and only if you received the object code
+with such an offer, in accord with subsection 6b.
+
+d) Convey the object code by offering access from a designated place (gratis
+or for a charge), and offer equivalent access to the Corresponding Source
+in the same way through the same place at no further charge. You need not
+require recipients to copy the Corresponding Source along with the object
+code. If the place to copy the object code is a network server, the Corresponding
+Source may be on a different server (operated by you or a third party) that
+supports equivalent copying facilities, provided you maintain clear directions
+next to the object code saying where to find the Corresponding Source. Regardless
+of what server hosts the Corresponding Source, you remain obligated to ensure
+that it is available for as long as needed to satisfy these requirements.
+
+e) Convey the object code using peer-to-peer transmission, provided you inform
+other peers where the object code and Corresponding Source of the work are
+being offered to the general public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded from
+the Corresponding Source as a System Library, need not be included in conveying
+the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any tangible
+personal property which is normally used for personal, family, or household
+purposes, or (2) anything designed or sold for incorporation into a dwelling.
+In determining whether a product is a consumer product, doubtful cases shall
+be resolved in favor of coverage. For a particular product received by a particular
+user, "normally used" refers to a typical or common use of that class of product,
+regardless of the status of the particular user or of the way in which the
+particular user actually uses, or expects or is expected to use, the product.
+A product is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent the
+only significant mode of use of the product.
+
+"Installation Information" for a User Product means any methods, procedures,
+authorization keys, or other information required to install and execute modified
+versions of a covered work in that User Product from a modified version of
+its Corresponding Source. The information must suffice to ensure that the
+continued functioning of the modified object code is in no case prevented
+or interfered with solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or specifically
+for use in, a User Product, and the conveying occurs as part of a transaction
+in which the right of possession and use of the User Product is transferred
+to the recipient in perpetuity or for a fixed term (regardless of how the
+transaction is characterized), the Corresponding Source conveyed under this
+section must be accompanied by the Installation Information. But this requirement
+does not apply if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has been installed
+in ROM).
+
+The requirement to provide Installation Information does not include a requirement
+to continue to provide support service, warranty, or updates for a work that
+has been modified or installed by the recipient, or for the User Product in
+which it has been modified or installed. Access to a network may be denied
+when the modification itself materially and adversely affects the operation
+of the network or violates the rules and protocols for communication across
+the network.
+
+Corresponding Source conveyed, and Installation Information provided, in accord
+with this section must be in a format that is publicly documented (and with
+an implementation available to the public in source code form), and must require
+no special password or key for unpacking, reading or copying.
+
+   7. Additional Terms.
+
+"Additional permissions" are terms that supplement the terms of this License
+by making exceptions from one or more of its conditions. Additional permissions
+that are applicable to the entire Program shall be treated as though they
+were included in this License, to the extent that they are valid under applicable
+law. If additional permissions apply only to part of the Program, that part
+may be used separately under those permissions, but the entire Program remains
+governed by this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option remove any
+additional permissions from that copy, or from any part of it. (Additional
+permissions may be written to require their own removal in certain cases when
+you modify the work.) You may place additional permissions on material, added
+by you to a covered work, for which you have or can give appropriate copyright
+permission.
+
+Notwithstanding any other provision of this License, for material you add
+to a covered work, you may (if authorized by the copyright holders of that
+material) supplement the terms of this License with terms:
+
+a) Disclaiming warranty or limiting liability differently from the terms of
+sections 15 and 16 of this License; or
+
+b) Requiring preservation of specified reasonable legal notices or author
+attributions in that material or in the Appropriate Legal Notices displayed
+by works containing it; or
+
+c) Prohibiting misrepresentation of the origin of that material, or requiring
+that modified versions of such material be marked in reasonable ways as different
+from the original version; or
+
+d) Limiting the use for publicity purposes of names of licensors or authors
+of the material; or
+
+e) Declining to grant rights under trademark law for use of some trade names,
+trademarks, or service marks; or
+
+f) Requiring indemnification of licensors and authors of that material by
+anyone who conveys the material (or modified versions of it) with contractual
+assumptions of liability to the recipient, for any liability that these contractual
+assumptions directly impose on those licensors and authors.
+
+All other non-permissive additional terms are considered "further restrictions"
+within the meaning of section 10. If the Program as you received it, or any
+part of it, contains a notice stating that it is governed by this License
+along with a term that is a further restriction, you may remove that term.
+If a license document contains a further restriction but permits relicensing
+or conveying under this License, you may add to a covered work material governed
+by the terms of that license document, provided that the further restriction
+does not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you must place,
+in the relevant source files, a statement of the additional terms that apply
+to those files, or a notice indicating where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the form
+of a separately written license, or stated as exceptions; the above requirements
+apply either way.
+
+   8. Termination.
+
+You may not propagate or modify a covered work except as expressly provided
+under this License. Any attempt otherwise to propagate or modify it is void,
+and will automatically terminate your rights under this License (including
+any patent licenses granted under the third paragraph of section 11).
+
+However, if you cease all violation of this License, then your license from
+a particular copyright holder is reinstated (a) provisionally, unless and
+until the copyright holder explicitly and finally terminates your license,
+and (b) permanently, if the copyright holder fails to notify you of the violation
+by some reasonable means prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is reinstated permanently
+if the copyright holder notifies you of the violation by some reasonable means,
+this is the first time you have received notice of violation of this License
+(for any work) from that copyright holder, and you cure the violation prior
+to 30 days after your receipt of the notice.
+
+Termination of your rights under this section does not terminate the licenses
+of parties who have received copies or rights from you under this License.
+If your rights have been terminated and not permanently reinstated, you do
+not qualify to receive new licenses for the same material under section 10.
+
+   9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run a copy
+of the Program. Ancillary propagation of a covered work occurring solely as
+a consequence of using peer-to-peer transmission to receive a copy likewise
+does not require acceptance. However, nothing other than this License grants
+you permission to propagate or modify any covered work. These actions infringe
+copyright if you do not accept this License. Therefore, by modifying or propagating
+a covered work, you indicate your acceptance of this License to do so.
+
+   10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically receives
+a license from the original licensors, to run, modify and propagate that work,
+subject to this License. You are not responsible for enforcing compliance
+by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an organization,
+or substantially all assets of one, or subdividing an organization, or merging
+organizations. If propagation of a covered work results from an entity transaction,
+each party to that transaction who receives a copy of the work also receives
+whatever licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the Corresponding
+Source of the work from the predecessor in interest, if the predecessor has
+it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the rights
+granted or affirmed under this License. For example, you may not impose a
+license fee, royalty, or other charge for exercise of rights granted under
+this License, and you may not initiate litigation (including a cross-claim
+or counterclaim in a lawsuit) alleging that any patent claim is infringed
+by making, using, selling, offering for sale, or importing the Program or
+any portion of it.
+
+   11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this License
+of the Program or a work on which the Program is based. The work thus licensed
+is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims owned or controlled
+by the contributor, whether already acquired or hereafter acquired, that would
+be infringed by some manner, permitted by this License, of making, using,
+or selling its contributor version, but do not include claims that would be
+infringed only as a consequence of further modification of the contributor
+version. For purposes of this definition, "control" includes the right to
+grant patent sublicenses in a manner consistent with the requirements of this
+License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free patent
+license under the contributor's essential patent claims, to make, use, sell,
+offer for sale, import and otherwise run, modify and propagate the contents
+of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express agreement
+or commitment, however denominated, not to enforce a patent (such as an express
+permission to practice a patent or covenant not to sue for patent infringement).
+To "grant" such a patent license to a party means to make such an agreement
+or commitment not to enforce a patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license, and the
+Corresponding Source of the work is not available for anyone to copy, free
+of charge and under the terms of this License, through a publicly available
+network server or other readily accessible means, then you must either (1)
+cause the Corresponding Source to be so available, or (2) arrange to deprive
+yourself of the benefit of the patent license for this particular work, or
+(3) arrange, in a manner consistent with the requirements of this License,
+to extend the patent license to downstream recipients. "Knowingly relying"
+means you have actual knowledge that, but for the patent license, your conveying
+the covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that country
+that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or arrangement,
+you convey, or propagate by procuring conveyance of, a covered work, and grant
+a patent license to some of the parties receiving the covered work authorizing
+them to use, propagate, modify or convey a specific copy of the covered work,
+then the patent license you grant is automatically extended to all recipients
+of the covered work and works based on it.
+
+A patent license is "discriminatory" if it does not include within the scope
+of its coverage, prohibits the exercise of, or is conditioned on the non-exercise
+of one or more of the rights that are specifically granted under this License.
+You may not convey a covered work if you are a party to an arrangement with
+a third party that is in the business of distributing software, under which
+you make payment to the third party based on the extent of your activity of
+conveying the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by you
+(or copies made from those copies), or (b) primarily for and in connection
+with specific products or compilations that contain the covered work, unless
+you entered into that arrangement, or that patent license was granted, prior
+to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting any implied
+license or other defenses to infringement that may otherwise be available
+to you under applicable patent law.
+
+   12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or otherwise)
+that contradict the conditions of this License, they do not excuse you from
+the conditions of this License. If you cannot convey a covered work so as
+to satisfy simultaneously your obligations under this License and any other
+pertinent obligations, then as a consequence you may not convey it at all.
+For example, if you agree to terms that obligate you to collect a royalty
+for further conveying from those to whom you convey the Program, the only
+way you could satisfy both those terms and this License would be to refrain
+entirely from conveying the Program.
+
+   13. Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have permission to
+link or combine any covered work with a work licensed under version 3 of the
+GNU Affero General Public License into a single combined work, and to convey
+the resulting work. The terms of this License will continue to apply to the
+part which is the covered work, but the special requirements of the GNU Affero
+General Public License, section 13, concerning interaction through a network
+will apply to the combination as such.
+
+   14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions of the
+GNU General Public License from time to time. Such new versions will be similar
+in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies
+that a certain numbered version of the GNU General Public License "or any
+later version" applies to it, you have the option of following the terms and
+conditions either of that numbered version or of any later version published
+by the Free Software Foundation. If the Program does not specify a version
+number of the GNU General Public License, you may choose any version ever
+published by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions of
+the GNU General Public License can be used, that proxy's public statement
+of acceptance of a version permanently authorizes you to choose that version
+for the Program.
+
+Later license versions may give you additional or different permissions. However,
+no additional obligations are imposed on any author or copyright holder as
+a result of your choosing to follow a later version.
+
+   15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
+LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
+OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
+PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+   16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
+ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM
+AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
+USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
+PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+   17. Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided above cannot
+be given local legal effect according to their terms, reviewing courts shall
+apply local law that most closely approximates an absolute waiver of all civil
+liability in connection with the Program, unless a warranty or assumption
+of liability accompanies a copy of the Program in return for a fee. END OF
+TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible
+use to the public, the best way to achieve this is to make it free software
+which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach
+them to the start of each source file to most effectively state the exclusion
+of warranty; and each file should have at least the "copyright" line and a
+pointer to where the full notice is found.
+
+<one line to give the program's name and a brief idea of what it does.>
+
+Copyright (C) <year> <name of author>
+
+This program is free software: you can redistribute it and/or modify it under
+the terms of the GNU General Public License as published by the Free Software
+Foundation, either version 3 of the License, or (at your option) any later
+version.
+
+This program is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
+FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
+
+You should have received a copy of the GNU General Public License along with
+this program. If not, see <http s ://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program does terminal interaction, make it output a short notice like
+this when it starts in an interactive mode:
+
+<program> Copyright (C) <year> <name of author>
+
+This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+
+This is free software, and you are welcome to redistribute it under certain
+conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands might
+be different; for a GUI interface, you would use an "about box".
+
+You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary. For
+more information on this, and how to apply and follow the GNU GPL, see <http
+s ://www.gnu.org/licenses/>.
+
+The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General Public
+License instead of this License. But first, please read <http s ://www.gnu.org/
+licenses /why-not-lgpl.html>.

+GNU GENERAL PUBLIC LICENSE
+
+Version 3, 29 June 2007
+
+Copyright © 2007 Free Software Foundation, Inc. <http s ://fsf.org/>
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The GNU General Public License is a free, copyleft license for software and
+other kinds of works.
+
+The licenses for most software and other practical works are designed to take
+away your freedom to share and change the works. By contrast, the GNU General
+Public License is intended to guarantee your freedom to share and change all
+versions of a program--to make sure it remains free software for all its users.
+We, the Free Software Foundation, use the GNU General Public License for most
+of our software; it applies also to any other work released this way by its
+authors. You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for them if you wish), that
+you receive source code or can get it if you want it, that you can change
+the software or use pieces of it in new free programs, and that you know you
+can do these things.
+
+To protect your rights, we need to prevent others from denying you these rights
+or asking you to surrender the rights. Therefore, you have certain responsibilities
+if you distribute copies of the software, or if you modify it: responsibilities
+to respect the freedom of others.
+
+For example, if you distribute copies of such a program, whether gratis or
+for a fee, you must pass on to the recipients the same freedoms that you received.
+You must make sure that they, too, receive or can get the source code. And
+you must show them these terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps: (1) assert
+copyright on the software, and (2) offer you this License giving you legal
+permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains that
+there is no warranty for this free software. For both users' and authors'
+sake, the GPL requires that modified versions be marked as changed, so that
+their problems will not be attributed erroneously to authors of previous versions.
+
+Some devices are designed to deny users access to install or run modified
+versions of the software inside them, although the manufacturer can do so.
+This is fundamentally incompatible with the aim of protecting users' freedom
+to change the software. The systematic pattern of such abuse occurs in the
+area of products for individuals to use, which is precisely where it is most
+unacceptable. Therefore, we have designed this version of the GPL to prohibit
+the practice for those products. If such problems arise substantially in other
+domains, we stand ready to extend this provision to those domains in future
+versions of the GPL, as needed to protect the freedom of users.
+
+Finally, every program is threatened constantly by software patents. States
+should not allow patents to restrict development and use of software on general-purpose
+computers, but in those that do, we wish to avoid the special danger that
+patents applied to a free program could make it effectively proprietary. To
+prevent this, the GPL assures that patents cannot be used to render the program
+non-free.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+TERMS AND CONDITIONS
+
+   0. Definitions.
+
+   "This License" refers to version 3 of the GNU General Public License.
+
+"Copyright" also means copyright-like laws that apply to other kinds of works,
+such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this License.
+Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals
+or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work in
+a fashion requiring copyright permission, other than the making of an exact
+copy. The resulting work is called a "modified version" of the earlier work
+or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based on the
+Program.
+
+To "propagate" a work means to do anything with it that, without permission,
+would make you directly or secondarily liable for infringement under applicable
+copyright law, except executing it on a computer or modifying a private copy.
+Propagation includes copying, distribution (with or without modification),
+making available to the public, and in some countries other activities as
+well.
+
+To "convey" a work means any kind of propagation that enables other parties
+to make or receive copies. Mere interaction with a user through a computer
+network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays "Appropriate Legal Notices" to the
+extent that it includes a convenient and prominently visible feature that
+(1) displays an appropriate copyright notice, and (2) tells the user that
+there is no warranty for the work (except to the extent that warranties are
+provided), that licensees may convey the work under this License, and how
+to view a copy of this License. If the interface presents a list of user commands
+or options, such as a menu, a prominent item in the list meets this criterion.
+
+   1. Source Code.
+
+The "source code" for a work means the preferred form of the work for making
+modifications to it. "Object code" means any non-source form of a work.
+
+A "Standard Interface" means an interface that either is an official standard
+defined by a recognized standards body, or, in the case of interfaces specified
+for a particular programming language, one that is widely used among developers
+working in that language.
+
+The "System Libraries" of an executable work include anything, other than
+the work as a whole, that (a) is included in the normal form of packaging
+a Major Component, but which is not part of that Major Component, and (b)
+serves only to enable use of the work with that Major Component, or to implement
+a Standard Interface for which an implementation is available to the public
+in source code form. A "Major Component", in this context, means a major essential
+component (kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to produce
+the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all the source
+code needed to generate, install, and (for an executable work) run the object
+code and to modify the work, including scripts to control those activities.
+However, it does not include the work's System Libraries, or general-purpose
+tools or generally available free programs which are used unmodified in performing
+those activities but which are not part of the work. For example, Corresponding
+Source includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically linked
+subprograms that the work is specifically designed to require, such as by
+intimate data communication or control flow between those subprograms and
+other parts of the work.
+
+The Corresponding Source need not include anything that users can regenerate
+automatically from other parts of the Corresponding Source.
+
+   The Corresponding Source for a work in source code form is that same work.
+
+   2. Basic Permissions.
+
+All rights granted under this License are granted for the term of copyright
+on the Program, and are irrevocable provided the stated conditions are met.
+This License explicitly affirms your unlimited permission to run the unmodified
+Program. The output from running a covered work is covered by this License
+only if the output, given its content, constitutes a covered work. This License
+acknowledges your rights of fair use or other equivalent, as provided by copyright
+law.
+
+You may make, run and propagate covered works that you do not convey, without
+conditions so long as your license otherwise remains in force. You may convey
+covered works to others for the sole purpose of having them make modifications
+exclusively for you, or provide you with facilities for running those works,
+provided that you comply with the terms of this License in conveying all material
+for which you do not control copyright. Those thus making or running the covered
+works for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of your copyrighted
+material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the conditions
+stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
+
+   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological measure
+under any applicable law fulfilling obligations under article 11 of the WIPO
+copyright treaty adopted on 20 December 1996, or similar laws prohibiting
+or restricting circumvention of such measures.
+
+When you convey a covered work, you waive any legal power to forbid circumvention
+of technological measures to the extent such circumvention is effected by
+exercising rights under this License with respect to the covered work, and
+you disclaim any intention to limit operation or modification of the work
+as a means of enforcing, against the work's users, your or third parties'
+legal rights to forbid circumvention of technological measures.
+
+   4. Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you receive
+it, in any medium, provided that you conspicuously and appropriately publish
+on each copy an appropriate copyright notice; keep intact all notices stating
+that this License and any non-permissive terms added in accord with section
+7 apply to the code; keep intact all notices of the absence of any warranty;
+and give all recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey, and you
+may offer support or warranty protection for a fee.
+
+   5. Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to produce
+it from the Program, in the form of source code under the terms of section
+4, provided that you also meet all of these conditions:
+
+a) The work must carry prominent notices stating that you modified it, and
+giving a relevant date.
+
+b) The work must carry prominent notices stating that it is released under
+this License and any conditions added under section 7. This requirement modifies
+the requirement in section 4 to "keep intact all notices".
+
+c) You must license the entire work, as a whole, under this License to anyone
+who comes into possession of a copy. This License will therefore apply, along
+with any applicable section 7 additional terms, to the whole of the work,
+and all its parts, regardless of how they are packaged. This License gives
+no permission to license the work in any other way, but it does not invalidate
+such permission if you have separately received it.
+
+d) If the work has interactive user interfaces, each must display Appropriate
+Legal Notices; however, if the Program has interactive interfaces that do
+not display Appropriate Legal Notices, your work need not make them do so.
+
+A compilation of a covered work with other separate and independent works,
+which are not by their nature extensions of the covered work, and which are
+not combined with it such as to form a larger program, in or on a volume of
+a storage or distribution medium, is called an "aggregate" if the compilation
+and its resulting copyright are not used to limit the access or legal rights
+of the compilation's users beyond what the individual works permit. Inclusion
+of a covered work in an aggregate does not cause this License to apply to
+the other parts of the aggregate.
+
+   6. Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of sections
+4 and 5, provided that you also convey the machine-readable Corresponding
+Source under the terms of this License, in one of these ways:
+
+a) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by the Corresponding Source fixed
+on a durable physical medium customarily used for software interchange.
+
+b) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by a written offer, valid for
+at least three years and valid for as long as you offer spare parts or customer
+support for that product model, to give anyone who possesses the object code
+either (1) a copy of the Corresponding Source for all the software in the
+product that is covered by this License, on a durable physical medium customarily
+used for software interchange, for a price no more than your reasonable cost
+of physically performing this conveying of source, or (2) access to copy the
+Corresponding Source from a network server at no charge.
+
+c) Convey individual copies of the object code with a copy of the written
+offer to provide the Corresponding Source. This alternative is allowed only
+occasionally and noncommercially, and only if you received the object code
+with such an offer, in accord with subsection 6b.
+
+d) Convey the object code by offering access from a designated place (gratis
+or for a charge), and offer equivalent access to the Corresponding Source
+in the same way through the same place at no further charge. You need not
+require recipients to copy the Corresponding Source along with the object
+code. If the place to copy the object code is a network server, the Corresponding
+Source may be on a different server (operated by you or a third party) that
+supports equivalent copying facilities, provided you maintain clear directions
+next to the object code saying where to find the Corresponding Source. Regardless
+of what server hosts the Corresponding Source, you remain obligated to ensure
+that it is available for as long as needed to satisfy these requirements.
+
+e) Convey the object code using peer-to-peer transmission, provided you inform
+other peers where the object code and Corresponding Source of the work are
+being offered to the general public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded from
+the Corresponding Source as a System Library, need not be included in conveying
+the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any tangible
+personal property which is normally used for personal, family, or household
+purposes, or (2) anything designed or sold for incorporation into a dwelling.
+In determining whether a product is a consumer product, doubtful cases shall
+be resolved in favor of coverage. For a particular product received by a particular
+user, "normally used" refers to a typical or common use of that class of product,
+regardless of the status of the particular user or of the way in which the
+particular user actually uses, or expects or is expected to use, the product.
+A product is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent the
+only significant mode of use of the product.
+
+"Installation Information" for a User Product means any methods, procedures,
+authorization keys, or other information required to install and execute modified
+versions of a covered work in that User Product from a modified version of
+its Corresponding Source. The information must suffice to ensure that the
+continued functioning of the modified object code is in no case prevented
+or interfered with solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or specifically
+for use in, a User Product, and the conveying occurs as part of a transaction
+in which the right of possession and use of the User Product is transferred
+to the recipient in perpetuity or for a fixed term (regardless of how the
+transaction is characterized), the Corresponding Source conveyed under this
+section must be accompanied by the Installation Information. But this requirement
+does not apply if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has been installed
+in ROM).
+
+The requirement to provide Installation Information does not include a requirement
+to continue to provide support service, warranty, or updates for a work that
+has been modified or installed by the recipient, or for the User Product in
+which it has been modified or installed. Access to a network may be denied
+when the modification itself materially and adversely affects the operation
+of the network or violates the rules and protocols for communication across
+the network.
+
+Corresponding Source conveyed, and Installation Information provided, in accord
+with this section must be in a format that is publicly documented (and with
+an implementation available to the public in source code form), and must require
+no special password or key for unpacking, reading or copying.
+
+   7. Additional Terms.
+
+"Additional permissions" are terms that supplement the terms of this License
+by making exceptions from one or more of its conditions. Additional permissions
+that are applicable to the entire Program shall be treated as though they
+were included in this License, to the extent that they are valid under applicable
+law. If additional permissions apply only to part of the Program, that part
+may be used separately under those permissions, but the entire Program remains
+governed by this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option remove any
+additional permissions from that copy, or from any part of it. (Additional
+permissions may be written to require their own removal in certain cases when
+you modify the work.) You may place additional permissions on material, added
+by you to a covered work, for which you have or can give appropriate copyright
+permission.
+
+Notwithstanding any other provision of this License, for material you add
+to a covered work, you may (if authorized by the copyright holders of that
+material) supplement the terms of this License with terms:
+
+a) Disclaiming warranty or limiting liability differently from the terms of
+sections 15 and 16 of this License; or
+
+b) Requiring preservation of specified reasonable legal notices or author
+attributions in that material or in the Appropriate Legal Notices displayed
+by works containing it; or
+
+c) Prohibiting misrepresentation of the origin of that material, or requiring
+that modified versions of such material be marked in reasonable ways as different
+from the original version; or
+
+d) Limiting the use for publicity purposes of names of licensors or authors
+of the material; or
+
+e) Declining to grant rights under trademark law for use of some trade names,
+trademarks, or service marks; or
+
+f) Requiring indemnification of licensors and authors of that material by
+anyone who conveys the material (or modified versions of it) with contractual
+assumptions of liability to the recipient, for any liability that these contractual
+assumptions directly impose on those licensors and authors.
+
+All other non-permissive additional terms are considered "further restrictions"
+within the meaning of section 10. If the Program as you received it, or any
+part of it, contains a notice stating that it is governed by this License
+along with a term that is a further restriction, you may remove that term.
+If a license document contains a further restriction but permits relicensing
+or conveying under this License, you may add to a covered work material governed
+by the terms of that license document, provided that the further restriction
+does not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you must place,
+in the relevant source files, a statement of the additional terms that apply
+to those files, or a notice indicating where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the form
+of a separately written license, or stated as exceptions; the above requirements
+apply either way.
+
+   8. Termination.
+
+You may not propagate or modify a covered work except as expressly provided
+under this License. Any attempt otherwise to propagate or modify it is void,
+and will automatically terminate your rights under this License (including
+any patent licenses granted under the third paragraph of section 11).
+
+However, if you cease all violation of this License, then your license from
+a particular copyright holder is reinstated (a) provisionally, unless and
+until the copyright holder explicitly and finally terminates your license,
+and (b) permanently, if the copyright holder fails to notify you of the violation
+by some reasonable means prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is reinstated permanently
+if the copyright holder notifies you of the violation by some reasonable means,
+this is the first time you have received notice of violation of this License
+(for any work) from that copyright holder, and you cure the violation prior
+to 30 days after your receipt of the notice.
+
+Termination of your rights under this section does not terminate the licenses
+of parties who have received copies or rights from you under this License.
+If your rights have been terminated and not permanently reinstated, you do
+not qualify to receive new licenses for the same material under section 10.
+
+   9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run a copy
+of the Program. Ancillary propagation of a covered work occurring solely as
+a consequence of using peer-to-peer transmission to receive a copy likewise
+does not require acceptance. However, nothing other than this License grants
+you permission to propagate or modify any covered work. These actions infringe
+copyright if you do not accept this License. Therefore, by modifying or propagating
+a covered work, you indicate your acceptance of this License to do so.
+
+   10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically receives
+a license from the original licensors, to run, modify and propagate that work,
+subject to this License. You are not responsible for enforcing compliance
+by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an organization,
+or substantially all assets of one, or subdividing an organization, or merging
+organizations. If propagation of a covered work results from an entity transaction,
+each party to that transaction who receives a copy of the work also receives
+whatever licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the Corresponding
+Source of the work from the predecessor in interest, if the predecessor has
+it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the rights
+granted or affirmed under this License. For example, you may not impose a
+license fee, royalty, or other charge for exercise of rights granted under
+this License, and you may not initiate litigation (including a cross-claim
+or counterclaim in a lawsuit) alleging that any patent claim is infringed
+by making, using, selling, offering for sale, or importing the Program or
+any portion of it.
+
+   11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this License
+of the Program or a work on which the Program is based. The work thus licensed
+is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims owned or controlled
+by the contributor, whether already acquired or hereafter acquired, that would
+be infringed by some manner, permitted by this License, of making, using,
+or selling its contributor version, but do not include claims that would be
+infringed only as a consequence of further modification of the contributor
+version. For purposes of this definition, "control" includes the right to
+grant patent sublicenses in a manner consistent with the requirements of this
+License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free patent
+license under the contributor's essential patent claims, to make, use, sell,
+offer for sale, import and otherwise run, modify and propagate the contents
+of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express agreement
+or commitment, however denominated, not to enforce a patent (such as an express
+permission to practice a patent or covenant not to sue for patent infringement).
+To "grant" such a patent license to a party means to make such an agreement
+or commitment not to enforce a patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license, and the
+Corresponding Source of the work is not available for anyone to copy, free
+of charge and under the terms of this License, through a publicly available
+network server or other readily accessible means, then you must either (1)
+cause the Corresponding Source to be so available, or (2) arrange to deprive
+yourself of the benefit of the patent license for this particular work, or
+(3) arrange, in a manner consistent with the requirements of this License,
+to extend the patent license to downstream recipients. "Knowingly relying"
+means you have actual knowledge that, but for the patent license, your conveying
+the covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that country
+that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or arrangement,
+you convey, or propagate by procuring conveyance of, a covered work, and grant
+a patent license to some of the parties receiving the covered work authorizing
+them to use, propagate, modify or convey a specific copy of the covered work,
+then the patent license you grant is automatically extended to all recipients
+of the covered work and works based on it.
+
+A patent license is "discriminatory" if it does not include within the scope
+of its coverage, prohibits the exercise of, or is conditioned on the non-exercise
+of one or more of the rights that are specifically granted under this License.
+You may not convey a covered work if you are a party to an arrangement with
+a third party that is in the business of distributing software, under which
+you make payment to the third party based on the extent of your activity of
+conveying the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by you
+(or copies made from those copies), or (b) primarily for and in connection
+with specific products or compilations that contain the covered work, unless
+you entered into that arrangement, or that patent license was granted, prior
+to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting any implied
+license or other defenses to infringement that may otherwise be available
+to you under applicable patent law.
+
+   12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or otherwise)
+that contradict the conditions of this License, they do not excuse you from
+the conditions of this License. If you cannot convey a covered work so as
+to satisfy simultaneously your obligations under this License and any other
+pertinent obligations, then as a consequence you may not convey it at all.
+For example, if you agree to terms that obligate you to collect a royalty
+for further conveying from those to whom you convey the Program, the only
+way you could satisfy both those terms and this License would be to refrain
+entirely from conveying the Program.
+
+   13. Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have permission to
+link or combine any covered work with a work licensed under version 3 of the
+GNU Affero General Public License into a single combined work, and to convey
+the resulting work. The terms of this License will continue to apply to the
+part which is the covered work, but the special requirements of the GNU Affero
+General Public License, section 13, concerning interaction through a network
+will apply to the combination as such.
+
+   14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions of the
+GNU General Public License from time to time. Such new versions will be similar
+in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies
+that a certain numbered version of the GNU General Public License "or any
+later version" applies to it, you have the option of following the terms and
+conditions either of that numbered version or of any later version published
+by the Free Software Foundation. If the Program does not specify a version
+number of the GNU General Public License, you may choose any version ever
+published by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions of
+the GNU General Public License can be used, that proxy's public statement
+of acceptance of a version permanently authorizes you to choose that version
+for the Program.
+
+Later license versions may give you additional or different permissions. However,
+no additional obligations are imposed on any author or copyright holder as
+a result of your choosing to follow a later version.
+
+   15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
+LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
+OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
+PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+   16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
+ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM
+AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
+USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
+PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+   17. Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided above cannot
+be given local legal effect according to their terms, reviewing courts shall
+apply local law that most closely approximates an absolute waiver of all civil
+liability in connection with the Program, unless a warranty or assumption
+of liability accompanies a copy of the Program in return for a fee. END OF
+TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible
+use to the public, the best way to achieve this is to make it free software
+which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach
+them to the start of each source file to most effectively state the exclusion
+of warranty; and each file should have at least the "copyright" line and a
+pointer to where the full notice is found.
+
+<one line to give the program's name and a brief idea of what it does.>
+
+Copyright (C) <year> <name of author>
+
+This program is free software: you can redistribute it and/or modify it under
+the terms of the GNU General Public License as published by the Free Software
+Foundation, either version 3 of the License, or (at your option) any later
+version.
+
+This program is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
+FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
+
+You should have received a copy of the GNU General Public License along with
+this program. If not, see <http s ://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program does terminal interaction, make it output a short notice like
+this when it starts in an interactive mode:
+
+<program> Copyright (C) <year> <name of author>
+
+This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+
+This is free software, and you are welcome to redistribute it under certain
+conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands might
+be different; for a GUI interface, you would use an "about box".
+
+You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary. For
+more information on this, and how to apply and follow the GNU GPL, see <http
+s ://www.gnu.org/licenses/>.
+
+The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General Public
+License instead of this License. But first, please read <http s ://www.gnu.org/
+licenses /why-not-lgpl.html>.

+GNU GENERAL PUBLIC LICENSE
+
+Version 3, 29 June 2007
+
+Copyright © 2007 Free Software Foundation, Inc. <http s ://fsf.org/>
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The GNU General Public License is a free, copyleft license for software and
+other kinds of works.
+
+The licenses for most software and other practical works are designed to take
+away your freedom to share and change the works. By contrast, the GNU General
+Public License is intended to guarantee your freedom to share and change all
+versions of a program--to make sure it remains free software for all its users.
+We, the Free Software Foundation, use the GNU General Public License for most
+of our software; it applies also to any other work released this way by its
+authors. You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for them if you wish), that
+you receive source code or can get it if you want it, that you can change
+the software or use pieces of it in new free programs, and that you know you
+can do these things.
+
+To protect your rights, we need to prevent others from denying you these rights
+or asking you to surrender the rights. Therefore, you have certain responsibilities
+if you distribute copies of the software, or if you modify it: responsibilities
+to respect the freedom of others.
+
+For example, if you distribute copies of such a program, whether gratis or
+for a fee, you must pass on to the recipients the same freedoms that you received.
+You must make sure that they, too, receive or can get the source code. And
+you must show them these terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps: (1) assert
+copyright on the software, and (2) offer you this License giving you legal
+permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains that
+there is no warranty for this free software. For both users' and authors'
+sake, the GPL requires that modified versions be marked as changed, so that
+their problems will not be attributed erroneously to authors of previous versions.
+
+Some devices are designed to deny users access to install or run modified
+versions of the software inside them, although the manufacturer can do so.
+This is fundamentally incompatible with the aim of protecting users' freedom
+to change the software. The systematic pattern of such abuse occurs in the
+area of products for individuals to use, which is precisely where it is most
+unacceptable. Therefore, we have designed this version of the GPL to prohibit
+the practice for those products. If such problems arise substantially in other
+domains, we stand ready to extend this provision to those domains in future
+versions of the GPL, as needed to protect the freedom of users.
+
+Finally, every program is threatened constantly by software patents. States
+should not allow patents to restrict development and use of software on general-purpose
+computers, but in those that do, we wish to avoid the special danger that
+patents applied to a free program could make it effectively proprietary. To
+prevent this, the GPL assures that patents cannot be used to render the program
+non-free.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+TERMS AND CONDITIONS
+
+   0. Definitions.
+
+   "This License" refers to version 3 of the GNU General Public License.
+
+"Copyright" also means copyright-like laws that apply to other kinds of works,
+such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this License.
+Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals
+or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work in
+a fashion requiring copyright permission, other than the making of an exact
+copy. The resulting work is called a "modified version" of the earlier work
+or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based on the
+Program.
+
+To "propagate" a work means to do anything with it that, without permission,
+would make you directly or secondarily liable for infringement under applicable
+copyright law, except executing it on a computer or modifying a private copy.
+Propagation includes copying, distribution (with or without modification),
+making available to the public, and in some countries other activities as
+well.
+
+To "convey" a work means any kind of propagation that enables other parties
+to make or receive copies. Mere interaction with a user through a computer
+network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays "Appropriate Legal Notices" to the
+extent that it includes a convenient and prominently visible feature that
+(1) displays an appropriate copyright notice, and (2) tells the user that
+there is no warranty for the work (except to the extent that warranties are
+provided), that licensees may convey the work under this License, and how
+to view a copy of this License. If the interface presents a list of user commands
+or options, such as a menu, a prominent item in the list meets this criterion.
+
+   1. Source Code.
+
+The "source code" for a work means the preferred form of the work for making
+modifications to it. "Object code" means any non-source form of a work.
+
+A "Standard Interface" means an interface that either is an official standard
+defined by a recognized standards body, or, in the case of interfaces specified
+for a particular programming language, one that is widely used among developers
+working in that language.
+
+The "System Libraries" of an executable work include anything, other than
+the work as a whole, that (a) is included in the normal form of packaging
+a Major Component, but which is not part of that Major Component, and (b)
+serves only to enable use of the work with that Major Component, or to implement
+a Standard Interface for which an implementation is available to the public
+in source code form. A "Major Component", in this context, means a major essential
+component (kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to produce
+the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all the source
+code needed to generate, install, and (for an executable work) run the object
+code and to modify the work, including scripts to control those activities.
+However, it does not include the work's System Libraries, or general-purpose
+tools or generally available free programs which are used unmodified in performing
+those activities but which are not part of the work. For example, Corresponding
+Source includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically linked
+subprograms that the work is specifically designed to require, such as by
+intimate data communication or control flow between those subprograms and
+other parts of the work.
+
+The Corresponding Source need not include anything that users can regenerate
+automatically from other parts of the Corresponding Source.
+
+   The Corresponding Source for a work in source code form is that same work.
+
+   2. Basic Permissions.
+
+All rights granted under this License are granted for the term of copyright
+on the Program, and are irrevocable provided the stated conditions are met.
+This License explicitly affirms your unlimited permission to run the unmodified
+Program. The output from running a covered work is covered by this License
+only if the output, given its content, constitutes a covered work. This License
+acknowledges your rights of fair use or other equivalent, as provided by copyright
+law.
+
+You may make, run and propagate covered works that you do not convey, without
+conditions so long as your license otherwise remains in force. You may convey
+covered works to others for the sole purpose of having them make modifications
+exclusively for you, or provide you with facilities for running those works,
+provided that you comply with the terms of this License in conveying all material
+for which you do not control copyright. Those thus making or running the covered
+works for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of your copyrighted
+material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the conditions
+stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
+
+   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological measure
+under any applicable law fulfilling obligations under article 11 of the WIPO
+copyright treaty adopted on 20 December 1996, or similar laws prohibiting
+or restricting circumvention of such measures.
+
+When you convey a covered work, you waive any legal power to forbid circumvention
+of technological measures to the extent such circumvention is effected by
+exercising rights under this License with respect to the covered work, and
+you disclaim any intention to limit operation or modification of the work
+as a means of enforcing, against the work's users, your or third parties'
+legal rights to forbid circumvention of technological measures.
+
+   4. Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you receive
+it, in any medium, provided that you conspicuously and appropriately publish
+on each copy an appropriate copyright notice; keep intact all notices stating
+that this License and any non-permissive terms added in accord with section
+7 apply to the code; keep intact all notices of the absence of any warranty;
+and give all recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey, and you
+may offer support or warranty protection for a fee.
+
+   5. Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to produce
+it from the Program, in the form of source code under the terms of section
+4, provided that you also meet all of these conditions:
+
+a) The work must carry prominent notices stating that you modified it, and
+giving a relevant date.
+
+b) The work must carry prominent notices stating that it is released under
+this License and any conditions added under section 7. This requirement modifies
+the requirement in section 4 to "keep intact all notices".
+
+c) You must license the entire work, as a whole, under this License to anyone
+who comes into possession of a copy. This License will therefore apply, along
+with any applicable section 7 additional terms, to the whole of the work,
+and all its parts, regardless of how they are packaged. This License gives
+no permission to license the work in any other way, but it does not invalidate
+such permission if you have separately received it.
+
+d) If the work has interactive user interfaces, each must display Appropriate
+Legal Notices; however, if the Program has interactive interfaces that do
+not display Appropriate Legal Notices, your work need not make them do so.
+
+A compilation of a covered work with other separate and independent works,
+which are not by their nature extensions of the covered work, and which are
+not combined with it such as to form a larger program, in or on a volume of
+a storage or distribution medium, is called an "aggregate" if the compilation
+and its resulting copyright are not used to limit the access or legal rights
+of the compilation's users beyond what the individual works permit. Inclusion
+of a covered work in an aggregate does not cause this License to apply to
+the other parts of the aggregate.
+
+   6. Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of sections
+4 and 5, provided that you also convey the machine-readable Corresponding
+Source under the terms of this License, in one of these ways:
+
+a) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by the Corresponding Source fixed
+on a durable physical medium customarily used for software interchange.
+
+b) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by a written offer, valid for
+at least three years and valid for as long as you offer spare parts or customer
+support for that product model, to give anyone who possesses the object code
+either (1) a copy of the Corresponding Source for all the software in the
+product that is covered by this License, on a durable physical medium customarily
+used for software interchange, for a price no more than your reasonable cost
+of physically performing this conveying of source, or (2) access to copy the
+Corresponding Source from a network server at no charge.
+
+c) Convey individual copies of the object code with a copy of the written
+offer to provide the Corresponding Source. This alternative is allowed only
+occasionally and noncommercially, and only if you received the object code
+with such an offer, in accord with subsection 6b.
+
+d) Convey the object code by offering access from a designated place (gratis
+or for a charge), and offer equivalent access to the Corresponding Source
+in the same way through the same place at no further charge. You need not
+require recipients to copy the Corresponding Source along with the object
+code. If the place to copy the object code is a network server, the Corresponding
+Source may be on a different server (operated by you or a third party) that
+supports equivalent copying facilities, provided you maintain clear directions
+next to the object code saying where to find the Corresponding Source. Regardless
+of what server hosts the Corresponding Source, you remain obligated to ensure
+that it is available for as long as needed to satisfy these requirements.
+
+e) Convey the object code using peer-to-peer transmission, provided you inform
+other peers where the object code and Corresponding Source of the work are
+being offered to the general public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded from
+the Corresponding Source as a System Library, need not be included in conveying
+the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any tangible
+personal property which is normally used for personal, family, or household
+purposes, or (2) anything designed or sold for incorporation into a dwelling.
+In determining whether a product is a consumer product, doubtful cases shall
+be resolved in favor of coverage. For a particular product received by a particular
+user, "normally used" refers to a typical or common use of that class of product,
+regardless of the status of the particular user or of the way in which the
+particular user actually uses, or expects or is expected to use, the product.
+A product is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent the
+only significant mode of use of the product.
+
+"Installation Information" for a User Product means any methods, procedures,
+authorization keys, or other information required to install and execute modified
+versions of a covered work in that User Product from a modified version of
+its Corresponding Source. The information must suffice to ensure that the
+continued functioning of the modified object code is in no case prevented
+or interfered with solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or specifically
+for use in, a User Product, and the conveying occurs as part of a transaction
+in which the right of possession and use of the User Product is transferred
+to the recipient in perpetuity or for a fixed term (regardless of how the
+transaction is characterized), the Corresponding Source conveyed under this
+section must be accompanied by the Installation Information. But this requirement
+does not apply if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has been installed
+in ROM).
+
+The requirement to provide Installation Information does not include a requirement
+to continue to provide support service, warranty, or updates for a work that
+has been modified or installed by the recipient, or for the User Product in
+which it has been modified or installed. Access to a network may be denied
+when the modification itself materially and adversely affects the operation
+of the network or violates the rules and protocols for communication across
+the network.
+
+Corresponding Source conveyed, and Installation Information provided, in accord
+with this section must be in a format that is publicly documented (and with
+an implementation available to the public in source code form), and must require
+no special password or key for unpacking, reading or copying.
+
+   7. Additional Terms.
+
+"Additional permissions" are terms that supplement the terms of this License
+by making exceptions from one or more of its conditions. Additional permissions
+that are applicable to the entire Program shall be treated as though they
+were included in this License, to the extent that they are valid under applicable
+law. If additional permissions apply only to part of the Program, that part
+may be used separately under those permissions, but the entire Program remains
+governed by this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option remove any
+additional permissions from that copy, or from any part of it. (Additional
+permissions may be written to require their own removal in certain cases when
+you modify the work.) You may place additional permissions on material, added
+by you to a covered work, for which you have or can give appropriate copyright
+permission.
+
+Notwithstanding any other provision of this License, for material you add
+to a covered work, you may (if authorized by the copyright holders of that
+material) supplement the terms of this License with terms:
+
+a) Disclaiming warranty or limiting liability differently from the terms of
+sections 15 and 16 of this License; or
+
+b) Requiring preservation of specified reasonable legal notices or author
+attributions in that material or in the Appropriate Legal Notices displayed
+by works containing it; or
+
+c) Prohibiting misrepresentation of the origin of that material, or requiring
+that modified versions of such material be marked in reasonable ways as different
+from the original version; or
+
+d) Limiting the use for publicity purposes of names of licensors or authors
+of the material; or
+
+e) Declining to grant rights under trademark law for use of some trade names,
+trademarks, or service marks; or
+
+f) Requiring indemnification of licensors and authors of that material by
+anyone who conveys the material (or modified versions of it) with contractual
+assumptions of liability to the recipient, for any liability that these contractual
+assumptions directly impose on those licensors and authors.
+
+All other non-permissive additional terms are considered "further restrictions"
+within the meaning of section 10. If the Program as you received it, or any
+part of it, contains a notice stating that it is governed by this License
+along with a term that is a further restriction, you may remove that term.
+If a license document contains a further restriction but permits relicensing
+or conveying under this License, you may add to a covered work material governed
+by the terms of that license document, provided that the further restriction
+does not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you must place,
+in the relevant source files, a statement of the additional terms that apply
+to those files, or a notice indicating where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the form
+of a separately written license, or stated as exceptions; the above requirements
+apply either way.
+
+   8. Termination.
+
+You may not propagate or modify a covered work except as expressly provided
+under this License. Any attempt otherwise to propagate or modify it is void,
+and will automatically terminate your rights under this License (including
+any patent licenses granted under the third paragraph of section 11).
+
+However, if you cease all violation of this License, then your license from
+a particular copyright holder is reinstated (a) provisionally, unless and
+until the copyright holder explicitly and finally terminates your license,
+and (b) permanently, if the copyright holder fails to notify you of the violation
+by some reasonable means prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is reinstated permanently
+if the copyright holder notifies you of the violation by some reasonable means,
+this is the first time you have received notice of violation of this License
+(for any work) from that copyright holder, and you cure the violation prior
+to 30 days after your receipt of the notice.
+
+Termination of your rights under this section does not terminate the licenses
+of parties who have received copies or rights from you under this License.
+If your rights have been terminated and not permanently reinstated, you do
+not qualify to receive new licenses for the same material under section 10.
+
+   9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run a copy
+of the Program. Ancillary propagation of a covered work occurring solely as
+a consequence of using peer-to-peer transmission to receive a copy likewise
+does not require acceptance. However, nothing other than this License grants
+you permission to propagate or modify any covered work. These actions infringe
+copyright if you do not accept this License. Therefore, by modifying or propagating
+a covered work, you indicate your acceptance of this License to do so.
+
+   10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically receives
+a license from the original licensors, to run, modify and propagate that work,
+subject to this License. You are not responsible for enforcing compliance
+by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an organization,
+or substantially all assets of one, or subdividing an organization, or merging
+organizations. If propagation of a covered work results from an entity transaction,
+each party to that transaction who receives a copy of the work also receives
+whatever licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the Corresponding
+Source of the work from the predecessor in interest, if the predecessor has
+it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the rights
+granted or affirmed under this License. For example, you may not impose a
+license fee, royalty, or other charge for exercise of rights granted under
+this License, and you may not initiate litigation (including a cross-claim
+or counterclaim in a lawsuit) alleging that any patent claim is infringed
+by making, using, selling, offering for sale, or importing the Program or
+any portion of it.
+
+   11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this License
+of the Program or a work on which the Program is based. The work thus licensed
+is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims owned or controlled
+by the contributor, whether already acquired or hereafter acquired, that would
+be infringed by some manner, permitted by this License, of making, using,
+or selling its contributor version, but do not include claims that would be
+infringed only as a consequence of further modification of the contributor
+version. For purposes of this definition, "control" includes the right to
+grant patent sublicenses in a manner consistent with the requirements of this
+License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free patent
+license under the contributor's essential patent claims, to make, use, sell,
+offer for sale, import and otherwise run, modify and propagate the contents
+of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express agreement
+or commitment, however denominated, not to enforce a patent (such as an express
+permission to practice a patent or covenant not to sue for patent infringement).
+To "grant" such a patent license to a party means to make such an agreement
+or commitment not to enforce a patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license, and the
+Corresponding Source of the work is not available for anyone to copy, free
+of charge and under the terms of this License, through a publicly available
+network server or other readily accessible means, then you must either (1)
+cause the Corresponding Source to be so available, or (2) arrange to deprive
+yourself of the benefit of the patent license for this particular work, or
+(3) arrange, in a manner consistent with the requirements of this License,
+to extend the patent license to downstream recipients. "Knowingly relying"
+means you have actual knowledge that, but for the patent license, your conveying
+the covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that country
+that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or arrangement,
+you convey, or propagate by procuring conveyance of, a covered work, and grant
+a patent license to some of the parties receiving the covered work authorizing
+them to use, propagate, modify or convey a specific copy of the covered work,
+then the patent license you grant is automatically extended to all recipients
+of the covered work and works based on it.
+
+A patent license is "discriminatory" if it does not include within the scope
+of its coverage, prohibits the exercise of, or is conditioned on the non-exercise
+of one or more of the rights that are specifically granted under this License.
+You may not convey a covered work if you are a party to an arrangement with
+a third party that is in the business of distributing software, under which
+you make payment to the third party based on the extent of your activity of
+conveying the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by you
+(or copies made from those copies), or (b) primarily for and in connection
+with specific products or compilations that contain the covered work, unless
+you entered into that arrangement, or that patent license was granted, prior
+to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting any implied
+license or other defenses to infringement that may otherwise be available
+to you under applicable patent law.
+
+   12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or otherwise)
+that contradict the conditions of this License, they do not excuse you from
+the conditions of this License. If you cannot convey a covered work so as
+to satisfy simultaneously your obligations under this License and any other
+pertinent obligations, then as a consequence you may not convey it at all.
+For example, if you agree to terms that obligate you to collect a royalty
+for further conveying from those to whom you convey the Program, the only
+way you could satisfy both those terms and this License would be to refrain
+entirely from conveying the Program.
+
+   13. Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have permission to
+link or combine any covered work with a work licensed under version 3 of the
+GNU Affero General Public License into a single combined work, and to convey
+the resulting work. The terms of this License will continue to apply to the
+part which is the covered work, but the special requirements of the GNU Affero
+General Public License, section 13, concerning interaction through a network
+will apply to the combination as such.
+
+   14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions of the
+GNU General Public License from time to time. Such new versions will be similar
+in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies
+that a certain numbered version of the GNU General Public License "or any
+later version" applies to it, you have the option of following the terms and
+conditions either of that numbered version or of any later version published
+by the Free Software Foundation. If the Program does not specify a version
+number of the GNU General Public License, you may choose any version ever
+published by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions of
+the GNU General Public License can be used, that proxy's public statement
+of acceptance of a version permanently authorizes you to choose that version
+for the Program.
+
+Later license versions may give you additional or different permissions. However,
+no additional obligations are imposed on any author or copyright holder as
+a result of your choosing to follow a later version.
+
+   15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
+LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
+OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
+PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+   16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
+ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM
+AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
+USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
+PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+   17. Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided above cannot
+be given local legal effect according to their terms, reviewing courts shall
+apply local law that most closely approximates an absolute waiver of all civil
+liability in connection with the Program, unless a warranty or assumption
+of liability accompanies a copy of the Program in return for a fee. END OF
+TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible
+use to the public, the best way to achieve this is to make it free software
+which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach
+them to the start of each source file to most effectively state the exclusion
+of warranty; and each file should have at least the "copyright" line and a
+pointer to where the full notice is found.
+
+<one line to give the program's name and a brief idea of what it does.>
+
+Copyright (C) <year> <name of author>
+
+This program is free software: you can redistribute it and/or modify it under
+the terms of the GNU General Public License as published by the Free Software
+Foundation, either version 3 of the License, or (at your option) any later
+version.
+
+This program is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
+FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
+
+You should have received a copy of the GNU General Public License along with
+this program. If not, see <http s ://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program does terminal interaction, make it output a short notice like
+this when it starts in an interactive mode:
+
+<program> Copyright (C) <year> <name of author>
+
+This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+
+This is free software, and you are welcome to redistribute it under certain
+conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands might
+be different; for a GUI interface, you would use an "about box".
+
+You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary. For
+more information on this, and how to apply and follow the GNU GPL, see <http
+s ://www.gnu.org/licenses/>.
+
+The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General Public
+License instead of this License. But first, please read <http s ://www.gnu.org/
+licenses /why-not-lgpl.html>.

+GNU GENERAL PUBLIC LICENSE
+
+Version 3, 29 June 2007
+
+Copyright © 2007 Free Software Foundation, Inc. <http s ://fsf.org/>
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The GNU General Public License is a free, copyleft license for software and
+other kinds of works.
+
+The licenses for most software and other practical works are designed to take
+away your freedom to share and change the works. By contrast, the GNU General
+Public License is intended to guarantee your freedom to share and change all
+versions of a program--to make sure it remains free software for all its users.
+We, the Free Software Foundation, use the GNU General Public License for most
+of our software; it applies also to any other work released this way by its
+authors. You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for them if you wish), that
+you receive source code or can get it if you want it, that you can change
+the software or use pieces of it in new free programs, and that you know you
+can do these things.
+
+To protect your rights, we need to prevent others from denying you these rights
+or asking you to surrender the rights. Therefore, you have certain responsibilities
+if you distribute copies of the software, or if you modify it: responsibilities
+to respect the freedom of others.
+
+For example, if you distribute copies of such a program, whether gratis or
+for a fee, you must pass on to the recipients the same freedoms that you received.
+You must make sure that they, too, receive or can get the source code. And
+you must show them these terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps: (1) assert
+copyright on the software, and (2) offer you this License giving you legal
+permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains that
+there is no warranty for this free software. For both users' and authors'
+sake, the GPL requires that modified versions be marked as changed, so that
+their problems will not be attributed erroneously to authors of previous versions.
+
+Some devices are designed to deny users access to install or run modified
+versions of the software inside them, although the manufacturer can do so.
+This is fundamentally incompatible with the aim of protecting users' freedom
+to change the software. The systematic pattern of such abuse occurs in the
+area of products for individuals to use, which is precisely where it is most
+unacceptable. Therefore, we have designed this version of the GPL to prohibit
+the practice for those products. If such problems arise substantially in other
+domains, we stand ready to extend this provision to those domains in future
+versions of the GPL, as needed to protect the freedom of users.
+
+Finally, every program is threatened constantly by software patents. States
+should not allow patents to restrict development and use of software on general-purpose
+computers, but in those that do, we wish to avoid the special danger that
+patents applied to a free program could make it effectively proprietary. To
+prevent this, the GPL assures that patents cannot be used to render the program
+non-free.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+TERMS AND CONDITIONS
+
+   0. Definitions.
+
+   "This License" refers to version 3 of the GNU General Public License.
+
+"Copyright" also means copyright-like laws that apply to other kinds of works,
+such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this License.
+Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals
+or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work in
+a fashion requiring copyright permission, other than the making of an exact
+copy. The resulting work is called a "modified version" of the earlier work
+or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based on the
+Program.
+
+To "propagate" a work means to do anything with it that, without permission,
+would make you directly or secondarily liable for infringement under applicable
+copyright law, except executing it on a computer or modifying a private copy.
+Propagation includes copying, distribution (with or without modification),
+making available to the public, and in some countries other activities as
+well.
+
+To "convey" a work means any kind of propagation that enables other parties
+to make or receive copies. Mere interaction with a user through a computer
+network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays "Appropriate Legal Notices" to the
+extent that it includes a convenient and prominently visible feature that
+(1) displays an appropriate copyright notice, and (2) tells the user that
+there is no warranty for the work (except to the extent that warranties are
+provided), that licensees may convey the work under this License, and how
+to view a copy of this License. If the interface presents a list of user commands
+or options, such as a menu, a prominent item in the list meets this criterion.
+
+   1. Source Code.
+
+The "source code" for a work means the preferred form of the work for making
+modifications to it. "Object code" means any non-source form of a work.
+
+A "Standard Interface" means an interface that either is an official standard
+defined by a recognized standards body, or, in the case of interfaces specified
+for a particular programming language, one that is widely used among developers
+working in that language.
+
+The "System Libraries" of an executable work include anything, other than
+the work as a whole, that (a) is included in the normal form of packaging
+a Major Component, but which is not part of that Major Component, and (b)
+serves only to enable use of the work with that Major Component, or to implement
+a Standard Interface for which an implementation is available to the public
+in source code form. A "Major Component", in this context, means a major essential
+component (kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to produce
+the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all the source
+code needed to generate, install, and (for an executable work) run the object
+code and to modify the work, including scripts to control those activities.
+However, it does not include the work's System Libraries, or general-purpose
+tools or generally available free programs which are used unmodified in performing
+those activities but which are not part of the work. For example, Corresponding
+Source includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically linked
+subprograms that the work is specifically designed to require, such as by
+intimate data communication or control flow between those subprograms and
+other parts of the work.
+
+The Corresponding Source need not include anything that users can regenerate
+automatically from other parts of the Corresponding Source.
+
+   The Corresponding Source for a work in source code form is that same work.
+
+   2. Basic Permissions.
+
+All rights granted under this License are granted for the term of copyright
+on the Program, and are irrevocable provided the stated conditions are met.
+This License explicitly affirms your unlimited permission to run the unmodified
+Program. The output from running a covered work is covered by this License
+only if the output, given its content, constitutes a covered work. This License
+acknowledges your rights of fair use or other equivalent, as provided by copyright
+law.
+
+You may make, run and propagate covered works that you do not convey, without
+conditions so long as your license otherwise remains in force. You may convey
+covered works to others for the sole purpose of having them make modifications
+exclusively for you, or provide you with facilities for running those works,
+provided that you comply with the terms of this License in conveying all material
+for which you do not control copyright. Those thus making or running the covered
+works for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of your copyrighted
+material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the conditions
+stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
+
+   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological measure
+under any applicable law fulfilling obligations under article 11 of the WIPO
+copyright treaty adopted on 20 December 1996, or similar laws prohibiting
+or restricting circumvention of such measures.
+
+When you convey a covered work, you waive any legal power to forbid circumvention
+of technological measures to the extent such circumvention is effected by
+exercising rights under this License with respect to the covered work, and
+you disclaim any intention to limit operation or modification of the work
+as a means of enforcing, against the work's users, your or third parties'
+legal rights to forbid circumvention of technological measures.
+
+   4. Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you receive
+it, in any medium, provided that you conspicuously and appropriately publish
+on each copy an appropriate copyright notice; keep intact all notices stating
+that this License and any non-permissive terms added in accord with section
+7 apply to the code; keep intact all notices of the absence of any warranty;
+and give all recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey, and you
+may offer support or warranty protection for a fee.
+
+   5. Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to produce
+it from the Program, in the form of source code under the terms of section
+4, provided that you also meet all of these conditions:
+
+a) The work must carry prominent notices stating that you modified it, and
+giving a relevant date.
+
+b) The work must carry prominent notices stating that it is released under
+this License and any conditions added under section 7. This requirement modifies
+the requirement in section 4 to "keep intact all notices".
+
+c) You must license the entire work, as a whole, under this License to anyone
+who comes into possession of a copy. This License will therefore apply, along
+with any applicable section 7 additional terms, to the whole of the work,
+and all its parts, regardless of how they are packaged. This License gives
+no permission to license the work in any other way, but it does not invalidate
+such permission if you have separately received it.
+
+d) If the work has interactive user interfaces, each must display Appropriate
+Legal Notices; however, if the Program has interactive interfaces that do
+not display Appropriate Legal Notices, your work need not make them do so.
+
+A compilation of a covered work with other separate and independent works,
+which are not by their nature extensions of the covered work, and which are
+not combined with it such as to form a larger program, in or on a volume of
+a storage or distribution medium, is called an "aggregate" if the compilation
+and its resulting copyright are not used to limit the access or legal rights
+of the compilation's users beyond what the individual works permit. Inclusion
+of a covered work in an aggregate does not cause this License to apply to
+the other parts of the aggregate.
+
+   6. Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of sections
+4 and 5, provided that you also convey the machine-readable Corresponding
+Source under the terms of this License, in one of these ways:
+
+a) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by the Corresponding Source fixed
+on a durable physical medium customarily used for software interchange.
+
+b) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by a written offer, valid for
+at least three years and valid for as long as you offer spare parts or customer
+support for that product model, to give anyone who possesses the object code
+either (1) a copy of the Corresponding Source for all the software in the
+product that is covered by this License, on a durable physical medium customarily
+used for software interchange, for a price no more than your reasonable cost
+of physically performing this conveying of source, or (2) access to copy the
+Corresponding Source from a network server at no charge.
+
+c) Convey individual copies of the object code with a copy of the written
+offer to provide the Corresponding Source. This alternative is allowed only
+occasionally and noncommercially, and only if you received the object code
+with such an offer, in accord with subsection 6b.
+
+d) Convey the object code by offering access from a designated place (gratis
+or for a charge), and offer equivalent access to the Corresponding Source
+in the same way through the same place at no further charge. You need not
+require recipients to copy the Corresponding Source along with the object
+code. If the place to copy the object code is a network server, the Corresponding
+Source may be on a different server (operated by you or a third party) that
+supports equivalent copying facilities, provided you maintain clear directions
+next to the object code saying where to find the Corresponding Source. Regardless
+of what server hosts the Corresponding Source, you remain obligated to ensure
+that it is available for as long as needed to satisfy these requirements.
+
+e) Convey the object code using peer-to-peer transmission, provided you inform
+other peers where the object code and Corresponding Source of the work are
+being offered to the general public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded from
+the Corresponding Source as a System Library, need not be included in conveying
+the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any tangible
+personal property which is normally used for personal, family, or household
+purposes, or (2) anything designed or sold for incorporation into a dwelling.
+In determining whether a product is a consumer product, doubtful cases shall
+be resolved in favor of coverage. For a particular product received by a particular
+user, "normally used" refers to a typical or common use of that class of product,
+regardless of the status of the particular user or of the way in which the
+particular user actually uses, or expects or is expected to use, the product.
+A product is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent the
+only significant mode of use of the product.
+
+"Installation Information" for a User Product means any methods, procedures,
+authorization keys, or other information required to install and execute modified
+versions of a covered work in that User Product from a modified version of
+its Corresponding Source. The information must suffice to ensure that the
+continued functioning of the modified object code is in no case prevented
+or interfered with solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or specifically
+for use in, a User Product, and the conveying occurs as part of a transaction
+in which the right of possession and use of the User Product is transferred
+to the recipient in perpetuity or for a fixed term (regardless of how the
+transaction is characterized), the Corresponding Source conveyed under this
+section must be accompanied by the Installation Information. But this requirement
+does not apply if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has been installed
+in ROM).
+
+The requirement to provide Installation Information does not include a requirement
+to continue to provide support service, warranty, or updates for a work that
+has been modified or installed by the recipient, or for the User Product in
+which it has been modified or installed. Access to a network may be denied
+when the modification itself materially and adversely affects the operation
+of the network or violates the rules and protocols for communication across
+the network.
+
+Corresponding Source conveyed, and Installation Information provided, in accord
+with this section must be in a format that is publicly documented (and with
+an implementation available to the public in source code form), and must require
+no special password or key for unpacking, reading or copying.
+
+   7. Additional Terms.
+
+"Additional permissions" are terms that supplement the terms of this License
+by making exceptions from one or more of its conditions. Additional permissions
+that are applicable to the entire Program shall be treated as though they
+were included in this License, to the extent that they are valid under applicable
+law. If additional permissions apply only to part of the Program, that part
+may be used separately under those permissions, but the entire Program remains
+governed by this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option remove any
+additional permissions from that copy, or from any part of it. (Additional
+permissions may be written to require their own removal in certain cases when
+you modify the work.) You may place additional permissions on material, added
+by you to a covered work, for which you have or can give appropriate copyright
+permission.
+
+Notwithstanding any other provision of this License, for material you add
+to a covered work, you may (if authorized by the copyright holders of that
+material) supplement the terms of this License with terms:
+
+a) Disclaiming warranty or limiting liability differently from the terms of
+sections 15 and 16 of this License; or
+
+b) Requiring preservation of specified reasonable legal notices or author
+attributions in that material or in the Appropriate Legal Notices displayed
+by works containing it; or
+
+c) Prohibiting misrepresentation of the origin of that material, or requiring
+that modified versions of such material be marked in reasonable ways as different
+from the original version; or
+
+d) Limiting the use for publicity purposes of names of licensors or authors
+of the material; or
+
+e) Declining to grant rights under trademark law for use of some trade names,
+trademarks, or service marks; or
+
+f) Requiring indemnification of licensors and authors of that material by
+anyone who conveys the material (or modified versions of it) with contractual
+assumptions of liability to the recipient, for any liability that these contractual
+assumptions directly impose on those licensors and authors.
+
+All other non-permissive additional terms are considered "further restrictions"
+within the meaning of section 10. If the Program as you received it, or any
+part of it, contains a notice stating that it is governed by this License
+along with a term that is a further restriction, you may remove that term.
+If a license document contains a further restriction but permits relicensing
+or conveying under this License, you may add to a covered work material governed
+by the terms of that license document, provided that the further restriction
+does not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you must place,
+in the relevant source files, a statement of the additional terms that apply
+to those files, or a notice indicating where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the form
+of a separately written license, or stated as exceptions; the above requirements
+apply either way.
+
+   8. Termination.
+
+You may not propagate or modify a covered work except as expressly provided
+under this License. Any attempt otherwise to propagate or modify it is void,
+and will automatically terminate your rights under this License (including
+any patent licenses granted under the third paragraph of section 11).
+
+However, if you cease all violation of this License, then your license from
+a particular copyright holder is reinstated (a) provisionally, unless and
+until the copyright holder explicitly and finally terminates your license,
+and (b) permanently, if the copyright holder fails to notify you of the violation
+by some reasonable means prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is reinstated permanently
+if the copyright holder notifies you of the violation by some reasonable means,
+this is the first time you have received notice of violation of this License
+(for any work) from that copyright holder, and you cure the violation prior
+to 30 days after your receipt of the notice.
+
+Termination of your rights under this section does not terminate the licenses
+of parties who have received copies or rights from you under this License.
+If your rights have been terminated and not permanently reinstated, you do
+not qualify to receive new licenses for the same material under section 10.
+
+   9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run a copy
+of the Program. Ancillary propagation of a covered work occurring solely as
+a consequence of using peer-to-peer transmission to receive a copy likewise
+does not require acceptance. However, nothing other than this License grants
+you permission to propagate or modify any covered work. These actions infringe
+copyright if you do not accept this License. Therefore, by modifying or propagating
+a covered work, you indicate your acceptance of this License to do so.
+
+   10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically receives
+a license from the original licensors, to run, modify and propagate that work,
+subject to this License. You are not responsible for enforcing compliance
+by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an organization,
+or substantially all assets of one, or subdividing an organization, or merging
+organizations. If propagation of a covered work results from an entity transaction,
+each party to that transaction who receives a copy of the work also receives
+whatever licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the Corresponding
+Source of the work from the predecessor in interest, if the predecessor has
+it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the rights
+granted or affirmed under this License. For example, you may not impose a
+license fee, royalty, or other charge for exercise of rights granted under
+this License, and you may not initiate litigation (including a cross-claim
+or counterclaim in a lawsuit) alleging that any patent claim is infringed
+by making, using, selling, offering for sale, or importing the Program or
+any portion of it.
+
+   11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this License
+of the Program or a work on which the Program is based. The work thus licensed
+is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims owned or controlled
+by the contributor, whether already acquired or hereafter acquired, that would
+be infringed by some manner, permitted by this License, of making, using,
+or selling its contributor version, but do not include claims that would be
+infringed only as a consequence of further modification of the contributor
+version. For purposes of this definition, "control" includes the right to
+grant patent sublicenses in a manner consistent with the requirements of this
+License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free patent
+license under the contributor's essential patent claims, to make, use, sell,
+offer for sale, import and otherwise run, modify and propagate the contents
+of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express agreement
+or commitment, however denominated, not to enforce a patent (such as an express
+permission to practice a patent or covenant not to sue for patent infringement).
+To "grant" such a patent license to a party means to make such an agreement
+or commitment not to enforce a patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license, and the
+Corresponding Source of the work is not available for anyone to copy, free
+of charge and under the terms of this License, through a publicly available
+network server or other readily accessible means, then you must either (1)
+cause the Corresponding Source to be so available, or (2) arrange to deprive
+yourself of the benefit of the patent license for this particular work, or
+(3) arrange, in a manner consistent with the requirements of this License,
+to extend the patent license to downstream recipients. "Knowingly relying"
+means you have actual knowledge that, but for the patent license, your conveying
+the covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that country
+that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or arrangement,
+you convey, or propagate by procuring conveyance of, a covered work, and grant
+a patent license to some of the parties receiving the covered work authorizing
+them to use, propagate, modify or convey a specific copy of the covered work,
+then the patent license you grant is automatically extended to all recipients
+of the covered work and works based on it.
+
+A patent license is "discriminatory" if it does not include within the scope
+of its coverage, prohibits the exercise of, or is conditioned on the non-exercise
+of one or more of the rights that are specifically granted under this License.
+You may not convey a covered work if you are a party to an arrangement with
+a third party that is in the business of distributing software, under which
+you make payment to the third party based on the extent of your activity of
+conveying the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by you
+(or copies made from those copies), or (b) primarily for and in connection
+with specific products or compilations that contain the covered work, unless
+you entered into that arrangement, or that patent license was granted, prior
+to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting any implied
+license or other defenses to infringement that may otherwise be available
+to you under applicable patent law.
+
+   12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or otherwise)
+that contradict the conditions of this License, they do not excuse you from
+the conditions of this License. If you cannot convey a covered work so as
+to satisfy simultaneously your obligations under this License and any other
+pertinent obligations, then as a consequence you may not convey it at all.
+For example, if you agree to terms that obligate you to collect a royalty
+for further conveying from those to whom you convey the Program, the only
+way you could satisfy both those terms and this License would be to refrain
+entirely from conveying the Program.
+
+   13. Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have permission to
+link or combine any covered work with a work licensed under version 3 of the
+GNU Affero General Public License into a single combined work, and to convey
+the resulting work. The terms of this License will continue to apply to the
+part which is the covered work, but the special requirements of the GNU Affero
+General Public License, section 13, concerning interaction through a network
+will apply to the combination as such.
+
+   14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions of the
+GNU General Public License from time to time. Such new versions will be similar
+in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies
+that a certain numbered version of the GNU General Public License "or any
+later version" applies to it, you have the option of following the terms and
+conditions either of that numbered version or of any later version published
+by the Free Software Foundation. If the Program does not specify a version
+number of the GNU General Public License, you may choose any version ever
+published by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions of
+the GNU General Public License can be used, that proxy's public statement
+of acceptance of a version permanently authorizes you to choose that version
+for the Program.
+
+Later license versions may give you additional or different permissions. However,
+no additional obligations are imposed on any author or copyright holder as
+a result of your choosing to follow a later version.
+
+   15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
+LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
+OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
+PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+   16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
+ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM
+AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
+USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
+PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+   17. Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided above cannot
+be given local legal effect according to their terms, reviewing courts shall
+apply local law that most closely approximates an absolute waiver of all civil
+liability in connection with the Program, unless a warranty or assumption
+of liability accompanies a copy of the Program in return for a fee. END OF
+TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible
+use to the public, the best way to achieve this is to make it free software
+which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach
+them to the start of each source file to most effectively state the exclusion
+of warranty; and each file should have at least the "copyright" line and a
+pointer to where the full notice is found.
+
+<one line to give the program's name and a brief idea of what it does.>
+
+Copyright (C) <year> <name of author>
+
+This program is free software: you can redistribute it and/or modify it under
+the terms of the GNU General Public License as published by the Free Software
+Foundation, either version 3 of the License, or (at your option) any later
+version.
+
+This program is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
+FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
+
+You should have received a copy of the GNU General Public License along with
+this program. If not, see <http s ://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program does terminal interaction, make it output a short notice like
+this when it starts in an interactive mode:
+
+<program> Copyright (C) <year> <name of author>
+
+This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+
+This is free software, and you are welcome to redistribute it under certain
+conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands might
+be different; for a GUI interface, you would use an "about box".
+
+You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary. For
+more information on this, and how to apply and follow the GNU GPL, see <http
+s ://www.gnu.org/licenses/>.
+
+The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General Public
+License instead of this License. But first, please read <http s ://www.gnu.org/
+licenses /why-not-lgpl.html>.

+GNU GENERAL PUBLIC LICENSE
+
+Version 3, 29 June 2007
+
+Copyright © 2007 Free Software Foundation, Inc. <http s ://fsf.org/>
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The GNU General Public License is a free, copyleft license for software and
+other kinds of works.
+
+The licenses for most software and other practical works are designed to take
+away your freedom to share and change the works. By contrast, the GNU General
+Public License is intended to guarantee your freedom to share and change all
+versions of a program--to make sure it remains free software for all its users.
+We, the Free Software Foundation, use the GNU General Public License for most
+of our software; it applies also to any other work released this way by its
+authors. You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for them if you wish), that
+you receive source code or can get it if you want it, that you can change
+the software or use pieces of it in new free programs, and that you know you
+can do these things.
+
+To protect your rights, we need to prevent others from denying you these rights
+or asking you to surrender the rights. Therefore, you have certain responsibilities
+if you distribute copies of the software, or if you modify it: responsibilities
+to respect the freedom of others.
+
+For example, if you distribute copies of such a program, whether gratis or
+for a fee, you must pass on to the recipients the same freedoms that you received.
+You must make sure that they, too, receive or can get the source code. And
+you must show them these terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps: (1) assert
+copyright on the software, and (2) offer you this License giving you legal
+permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains that
+there is no warranty for this free software. For both users' and authors'
+sake, the GPL requires that modified versions be marked as changed, so that
+their problems will not be attributed erroneously to authors of previous versions.
+
+Some devices are designed to deny users access to install or run modified
+versions of the software inside them, although the manufacturer can do so.
+This is fundamentally incompatible with the aim of protecting users' freedom
+to change the software. The systematic pattern of such abuse occurs in the
+area of products for individuals to use, which is precisely where it is most
+unacceptable. Therefore, we have designed this version of the GPL to prohibit
+the practice for those products. If such problems arise substantially in other
+domains, we stand ready to extend this provision to those domains in future
+versions of the GPL, as needed to protect the freedom of users.
+
+Finally, every program is threatened constantly by software patents. States
+should not allow patents to restrict development and use of software on general-purpose
+computers, but in those that do, we wish to avoid the special danger that
+patents applied to a free program could make it effectively proprietary. To
+prevent this, the GPL assures that patents cannot be used to render the program
+non-free.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+TERMS AND CONDITIONS
+
+   0. Definitions.
+
+   "This License" refers to version 3 of the GNU General Public License.
+
+"Copyright" also means copyright-like laws that apply to other kinds of works,
+such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this License.
+Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals
+or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work in
+a fashion requiring copyright permission, other than the making of an exact
+copy. The resulting work is called a "modified version" of the earlier work
+or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based on the
+Program.
+
+To "propagate" a work means to do anything with it that, without permission,
+would make you directly or secondarily liable for infringement under applicable
+copyright law, except executing it on a computer or modifying a private copy.
+Propagation includes copying, distribution (with or without modification),
+making available to the public, and in some countries other activities as
+well.
+
+To "convey" a work means any kind of propagation that enables other parties
+to make or receive copies. Mere interaction with a user through a computer
+network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays "Appropriate Legal Notices" to the
+extent that it includes a convenient and prominently visible feature that
+(1) displays an appropriate copyright notice, and (2) tells the user that
+there is no warranty for the work (except to the extent that warranties are
+provided), that licensees may convey the work under this License, and how
+to view a copy of this License. If the interface presents a list of user commands
+or options, such as a menu, a prominent item in the list meets this criterion.
+
+   1. Source Code.
+
+The "source code" for a work means the preferred form of the work for making
+modifications to it. "Object code" means any non-source form of a work.
+
+A "Standard Interface" means an interface that either is an official standard
+defined by a recognized standards body, or, in the case of interfaces specified
+for a particular programming language, one that is widely used among developers
+working in that language.
+
+The "System Libraries" of an executable work include anything, other than
+the work as a whole, that (a) is included in the normal form of packaging
+a Major Component, but which is not part of that Major Component, and (b)
+serves only to enable use of the work with that Major Component, or to implement
+a Standard Interface for which an implementation is available to the public
+in source code form. A "Major Component", in this context, means a major essential
+component (kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to produce
+the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all the source
+code needed to generate, install, and (for an executable work) run the object
+code and to modify the work, including scripts to control those activities.
+However, it does not include the work's System Libraries, or general-purpose
+tools or generally available free programs which are used unmodified in performing
+those activities but which are not part of the work. For example, Corresponding
+Source includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically linked
+subprograms that the work is specifically designed to require, such as by
+intimate data communication or control flow between those subprograms and
+other parts of the work.
+
+The Corresponding Source need not include anything that users can regenerate
+automatically from other parts of the Corresponding Source.
+
+   The Corresponding Source for a work in source code form is that same work.
+
+   2. Basic Permissions.
+
+All rights granted under this License are granted for the term of copyright
+on the Program, and are irrevocable provided the stated conditions are met.
+This License explicitly affirms your unlimited permission to run the unmodified
+Program. The output from running a covered work is covered by this License
+only if the output, given its content, constitutes a covered work. This License
+acknowledges your rights of fair use or other equivalent, as provided by copyright
+law.
+
+You may make, run and propagate covered works that you do not convey, without
+conditions so long as your license otherwise remains in force. You may convey
+covered works to others for the sole purpose of having them make modifications
+exclusively for you, or provide you with facilities for running those works,
+provided that you comply with the terms of this License in conveying all material
+for which you do not control copyright. Those thus making or running the covered
+works for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of your copyrighted
+material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the conditions
+stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
+
+   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological measure
+under any applicable law fulfilling obligations under article 11 of the WIPO
+copyright treaty adopted on 20 December 1996, or similar laws prohibiting
+or restricting circumvention of such measures.
+
+When you convey a covered work, you waive any legal power to forbid circumvention
+of technological measures to the extent such circumvention is effected by
+exercising rights under this License with respect to the covered work, and
+you disclaim any intention to limit operation or modification of the work
+as a means of enforcing, against the work's users, your or third parties'
+legal rights to forbid circumvention of technological measures.
+
+   4. Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you receive
+it, in any medium, provided that you conspicuously and appropriately publish
+on each copy an appropriate copyright notice; keep intact all notices stating
+that this License and any non-permissive terms added in accord with section
+7 apply to the code; keep intact all notices of the absence of any warranty;
+and give all recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey, and you
+may offer support or warranty protection for a fee.
+
+   5. Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to produce
+it from the Program, in the form of source code under the terms of section
+4, provided that you also meet all of these conditions:
+
+a) The work must carry prominent notices stating that you modified it, and
+giving a relevant date.
+
+b) The work must carry prominent notices stating that it is released under
+this License and any conditions added under section 7. This requirement modifies
+the requirement in section 4 to "keep intact all notices".
+
+c) You must license the entire work, as a whole, under this License to anyone
+who comes into possession of a copy. This License will therefore apply, along
+with any applicable section 7 additional terms, to the whole of the work,
+and all its parts, regardless of how they are packaged. This License gives
+no permission to license the work in any other way, but it does not invalidate
+such permission if you have separately received it.
+
+d) If the work has interactive user interfaces, each must display Appropriate
+Legal Notices; however, if the Program has interactive interfaces that do
+not display Appropriate Legal Notices, your work need not make them do so.
+
+A compilation of a covered work with other separate and independent works,
+which are not by their nature extensions of the covered work, and which are
+not combined with it such as to form a larger program, in or on a volume of
+a storage or distribution medium, is called an "aggregate" if the compilation
+and its resulting copyright are not used to limit the access or legal rights
+of the compilation's users beyond what the individual works permit. Inclusion
+of a covered work in an aggregate does not cause this License to apply to
+the other parts of the aggregate.
+
+   6. Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of sections
+4 and 5, provided that you also convey the machine-readable Corresponding
+Source under the terms of this License, in one of these ways:
+
+a) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by the Corresponding Source fixed
+on a durable physical medium customarily used for software interchange.
+
+b) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by a written offer, valid for
+at least three years and valid for as long as you offer spare parts or customer
+support for that product model, to give anyone who possesses the object code
+either (1) a copy of the Corresponding Source for all the software in the
+product that is covered by this License, on a durable physical medium customarily
+used for software interchange, for a price no more than your reasonable cost
+of physically performing this conveying of source, or (2) access to copy the
+Corresponding Source from a network server at no charge.
+
+c) Convey individual copies of the object code with a copy of the written
+offer to provide the Corresponding Source. This alternative is allowed only
+occasionally and noncommercially, and only if you received the object code
+with such an offer, in accord with subsection 6b.
+
+d) Convey the object code by offering access from a designated place (gratis
+or for a charge), and offer equivalent access to the Corresponding Source
+in the same way through the same place at no further charge. You need not
+require recipients to copy the Corresponding Source along with the object
+code. If the place to copy the object code is a network server, the Corresponding
+Source may be on a different server (operated by you or a third party) that
+supports equivalent copying facilities, provided you maintain clear directions
+next to the object code saying where to find the Corresponding Source. Regardless
+of what server hosts the Corresponding Source, you remain obligated to ensure
+that it is available for as long as needed to satisfy these requirements.
+
+e) Convey the object code using peer-to-peer transmission, provided you inform
+other peers where the object code and Corresponding Source of the work are
+being offered to the general public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded from
+the Corresponding Source as a System Library, need not be included in conveying
+the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any tangible
+personal property which is normally used for personal, family, or household
+purposes, or (2) anything designed or sold for incorporation into a dwelling.
+In determining whether a product is a consumer product, doubtful cases shall
+be resolved in favor of coverage. For a particular product received by a particular
+user, "normally used" refers to a typical or common use of that class of product,
+regardless of the status of the particular user or of the way in which the
+particular user actually uses, or expects or is expected to use, the product.
+A product is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent the
+only significant mode of use of the product.
+
+"Installation Information" for a User Product means any methods, procedures,
+authorization keys, or other information required to install and execute modified
+versions of a covered work in that User Product from a modified version of
+its Corresponding Source. The information must suffice to ensure that the
+continued functioning of the modified object code is in no case prevented
+or interfered with solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or specifically
+for use in, a User Product, and the conveying occurs as part of a transaction
+in which the right of possession and use of the User Product is transferred
+to the recipient in perpetuity or for a fixed term (regardless of how the
+transaction is characterized), the Corresponding Source conveyed under this
+section must be accompanied by the Installation Information. But this requirement
+does not apply if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has been installed
+in ROM).
+
+The requirement to provide Installation Information does not include a requirement
+to continue to provide support service, warranty, or updates for a work that
+has been modified or installed by the recipient, or for the User Product in
+which it has been modified or installed. Access to a network may be denied
+when the modification itself materially and adversely affects the operation
+of the network or violates the rules and protocols for communication across
+the network.
+
+Corresponding Source conveyed, and Installation Information provided, in accord
+with this section must be in a format that is publicly documented (and with
+an implementation available to the public in source code form), and must require
+no special password or key for unpacking, reading or copying.
+
+   7. Additional Terms.
+
+"Additional permissions" are terms that supplement the terms of this License
+by making exceptions from one or more of its conditions. Additional permissions
+that are applicable to the entire Program shall be treated as though they
+were included in this License, to the extent that they are valid under applicable
+law. If additional permissions apply only to part of the Program, that part
+may be used separately under those permissions, but the entire Program remains
+governed by this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option remove any
+additional permissions from that copy, or from any part of it. (Additional
+permissions may be written to require their own removal in certain cases when
+you modify the work.) You may place additional permissions on material, added
+by you to a covered work, for which you have or can give appropriate copyright
+permission.
+
+Notwithstanding any other provision of this License, for material you add
+to a covered work, you may (if authorized by the copyright holders of that
+material) supplement the terms of this License with terms:
+
+a) Disclaiming warranty or limiting liability differently from the terms of
+sections 15 and 16 of this License; or
+
+b) Requiring preservation of specified reasonable legal notices or author
+attributions in that material or in the Appropriate Legal Notices displayed
+by works containing it; or
+
+c) Prohibiting misrepresentation of the origin of that material, or requiring
+that modified versions of such material be marked in reasonable ways as different
+from the original version; or
+
+d) Limiting the use for publicity purposes of names of licensors or authors
+of the material; or
+
+e) Declining to grant rights under trademark law for use of some trade names,
+trademarks, or service marks; or
+
+f) Requiring indemnification of licensors and authors of that material by
+anyone who conveys the material (or modified versions of it) with contractual
+assumptions of liability to the recipient, for any liability that these contractual
+assumptions directly impose on those licensors and authors.
+
+All other non-permissive additional terms are considered "further restrictions"
+within the meaning of section 10. If the Program as you received it, or any
+part of it, contains a notice stating that it is governed by this License
+along with a term that is a further restriction, you may remove that term.
+If a license document contains a further restriction but permits relicensing
+or conveying under this License, you may add to a covered work material governed
+by the terms of that license document, provided that the further restriction
+does not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you must place,
+in the relevant source files, a statement of the additional terms that apply
+to those files, or a notice indicating where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the form
+of a separately written license, or stated as exceptions; the above requirements
+apply either way.
+
+   8. Termination.
+
+You may not propagate or modify a covered work except as expressly provided
+under this License. Any attempt otherwise to propagate or modify it is void,
+and will automatically terminate your rights under this License (including
+any patent licenses granted under the third paragraph of section 11).
+
+However, if you cease all violation of this License, then your license from
+a particular copyright holder is reinstated (a) provisionally, unless and
+until the copyright holder explicitly and finally terminates your license,
+and (b) permanently, if the copyright holder fails to notify you of the violation
+by some reasonable means prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is reinstated permanently
+if the copyright holder notifies you of the violation by some reasonable means,
+this is the first time you have received notice of violation of this License
+(for any work) from that copyright holder, and you cure the violation prior
+to 30 days after your receipt of the notice.
+
+Termination of your rights under this section does not terminate the licenses
+of parties who have received copies or rights from you under this License.
+If your rights have been terminated and not permanently reinstated, you do
+not qualify to receive new licenses for the same material under section 10.
+
+   9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run a copy
+of the Program. Ancillary propagation of a covered work occurring solely as
+a consequence of using peer-to-peer transmission to receive a copy likewise
+does not require acceptance. However, nothing other than this License grants
+you permission to propagate or modify any covered work. These actions infringe
+copyright if you do not accept this License. Therefore, by modifying or propagating
+a covered work, you indicate your acceptance of this License to do so.
+
+   10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically receives
+a license from the original licensors, to run, modify and propagate that work,
+subject to this License. You are not responsible for enforcing compliance
+by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an organization,
+or substantially all assets of one, or subdividing an organization, or merging
+organizations. If propagation of a covered work results from an entity transaction,
+each party to that transaction who receives a copy of the work also receives
+whatever licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the Corresponding
+Source of the work from the predecessor in interest, if the predecessor has
+it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the rights
+granted or affirmed under this License. For example, you may not impose a
+license fee, royalty, or other charge for exercise of rights granted under
+this License, and you may not initiate litigation (including a cross-claim
+or counterclaim in a lawsuit) alleging that any patent claim is infringed
+by making, using, selling, offering for sale, or importing the Program or
+any portion of it.
+
+   11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this License
+of the Program or a work on which the Program is based. The work thus licensed
+is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims owned or controlled
+by the contributor, whether already acquired or hereafter acquired, that would
+be infringed by some manner, permitted by this License, of making, using,
+or selling its contributor version, but do not include claims that would be
+infringed only as a consequence of further modification of the contributor
+version. For purposes of this definition, "control" includes the right to
+grant patent sublicenses in a manner consistent with the requirements of this
+License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free patent
+license under the contributor's essential patent claims, to make, use, sell,
+offer for sale, import and otherwise run, modify and propagate the contents
+of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express agreement
+or commitment, however denominated, not to enforce a patent (such as an express
+permission to practice a patent or covenant not to sue for patent infringement).
+To "grant" such a patent license to a party means to make such an agreement
+or commitment not to enforce a patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license, and the
+Corresponding Source of the work is not available for anyone to copy, free
+of charge and under the terms of this License, through a publicly available
+network server or other readily accessible means, then you must either (1)
+cause the Corresponding Source to be so available, or (2) arrange to deprive
+yourself of the benefit of the patent license for this particular work, or
+(3) arrange, in a manner consistent with the requirements of this License,
+to extend the patent license to downstream recipients. "Knowingly relying"
+means you have actual knowledge that, but for the patent license, your conveying
+the covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that country
+that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or arrangement,
+you convey, or propagate by procuring conveyance of, a covered work, and grant
+a patent license to some of the parties receiving the covered work authorizing
+them to use, propagate, modify or convey a specific copy of the covered work,
+then the patent license you grant is automatically extended to all recipients
+of the covered work and works based on it.
+
+A patent license is "discriminatory" if it does not include within the scope
+of its coverage, prohibits the exercise of, or is conditioned on the non-exercise
+of one or more of the rights that are specifically granted under this License.
+You may not convey a covered work if you are a party to an arrangement with
+a third party that is in the business of distributing software, under which
+you make payment to the third party based on the extent of your activity of
+conveying the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by you
+(or copies made from those copies), or (b) primarily for and in connection
+with specific products or compilations that contain the covered work, unless
+you entered into that arrangement, or that patent license was granted, prior
+to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting any implied
+license or other defenses to infringement that may otherwise be available
+to you under applicable patent law.
+
+   12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or otherwise)
+that contradict the conditions of this License, they do not excuse you from
+the conditions of this License. If you cannot convey a covered work so as
+to satisfy simultaneously your obligations under this License and any other
+pertinent obligations, then as a consequence you may not convey it at all.
+For example, if you agree to terms that obligate you to collect a royalty
+for further conveying from those to whom you convey the Program, the only
+way you could satisfy both those terms and this License would be to refrain
+entirely from conveying the Program.
+
+   13. Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have permission to
+link or combine any covered work with a work licensed under version 3 of the
+GNU Affero General Public License into a single combined work, and to convey
+the resulting work. The terms of this License will continue to apply to the
+part which is the covered work, but the special requirements of the GNU Affero
+General Public License, section 13, concerning interaction through a network
+will apply to the combination as such.
+
+   14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions of the
+GNU General Public License from time to time. Such new versions will be similar
+in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies
+that a certain numbered version of the GNU General Public License "or any
+later version" applies to it, you have the option of following the terms and
+conditions either of that numbered version or of any later version published
+by the Free Software Foundation. If the Program does not specify a version
+number of the GNU General Public License, you may choose any version ever
+published by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions of
+the GNU General Public License can be used, that proxy's public statement
+of acceptance of a version permanently authorizes you to choose that version
+for the Program.
+
+Later license versions may give you additional or different permissions. However,
+no additional obligations are imposed on any author or copyright holder as
+a result of your choosing to follow a later version.
+
+   15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
+LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
+OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
+PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+   16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
+ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM
+AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
+USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
+PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+   17. Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided above cannot
+be given local legal effect according to their terms, reviewing courts shall
+apply local law that most closely approximates an absolute waiver of all civil
+liability in connection with the Program, unless a warranty or assumption
+of liability accompanies a copy of the Program in return for a fee. END OF
+TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible
+use to the public, the best way to achieve this is to make it free software
+which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach
+them to the start of each source file to most effectively state the exclusion
+of warranty; and each file should have at least the "copyright" line and a
+pointer to where the full notice is found.
+
+<one line to give the program's name and a brief idea of what it does.>
+
+Copyright (C) <year> <name of author>
+
+This program is free software: you can redistribute it and/or modify it under
+the terms of the GNU General Public License as published by the Free Software
+Foundation, either version 3 of the License, or (at your option) any later
+version.
+
+This program is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
+FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
+
+You should have received a copy of the GNU General Public License along with
+this program. If not, see <http s ://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program does terminal interaction, make it output a short notice like
+this when it starts in an interactive mode:
+
+<program> Copyright (C) <year> <name of author>
+
+This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+
+This is free software, and you are welcome to redistribute it under certain
+conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands might
+be different; for a GUI interface, you would use an "about box".
+
+You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary. For
+more information on this, and how to apply and follow the GNU GPL, see <http
+s ://www.gnu.org/licenses/>.
+
+The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General Public
+License instead of this License. But first, please read <http s ://www.gnu.org/
+licenses /why-not-lgpl.html>.

+GNU GENERAL PUBLIC LICENSE
+
+Version 3, 29 June 2007
+
+Copyright © 2007 Free Software Foundation, Inc. <http s ://fsf.org/>
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The GNU General Public License is a free, copyleft license for software and
+other kinds of works.
+
+The licenses for most software and other practical works are designed to take
+away your freedom to share and change the works. By contrast, the GNU General
+Public License is intended to guarantee your freedom to share and change all
+versions of a program--to make sure it remains free software for all its users.
+We, the Free Software Foundation, use the GNU General Public License for most
+of our software; it applies also to any other work released this way by its
+authors. You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for them if you wish), that
+you receive source code or can get it if you want it, that you can change
+the software or use pieces of it in new free programs, and that you know you
+can do these things.
+
+To protect your rights, we need to prevent others from denying you these rights
+or asking you to surrender the rights. Therefore, you have certain responsibilities
+if you distribute copies of the software, or if you modify it: responsibilities
+to respect the freedom of others.
+
+For example, if you distribute copies of such a program, whether gratis or
+for a fee, you must pass on to the recipients the same freedoms that you received.
+You must make sure that they, too, receive or can get the source code. And
+you must show them these terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps: (1) assert
+copyright on the software, and (2) offer you this License giving you legal
+permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains that
+there is no warranty for this free software. For both users' and authors'
+sake, the GPL requires that modified versions be marked as changed, so that
+their problems will not be attributed erroneously to authors of previous versions.
+
+Some devices are designed to deny users access to install or run modified
+versions of the software inside them, although the manufacturer can do so.
+This is fundamentally incompatible with the aim of protecting users' freedom
+to change the software. The systematic pattern of such abuse occurs in the
+area of products for individuals to use, which is precisely where it is most
+unacceptable. Therefore, we have designed this version of the GPL to prohibit
+the practice for those products. If such problems arise substantially in other
+domains, we stand ready to extend this provision to those domains in future
+versions of the GPL, as needed to protect the freedom of users.
+
+Finally, every program is threatened constantly by software patents. States
+should not allow patents to restrict development and use of software on general-purpose
+computers, but in those that do, we wish to avoid the special danger that
+patents applied to a free program could make it effectively proprietary. To
+prevent this, the GPL assures that patents cannot be used to render the program
+non-free.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+TERMS AND CONDITIONS
+
+   0. Definitions.
+
+   "This License" refers to version 3 of the GNU General Public License.
+
+"Copyright" also means copyright-like laws that apply to other kinds of works,
+such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this License.
+Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals
+or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work in
+a fashion requiring copyright permission, other than the making of an exact
+copy. The resulting work is called a "modified version" of the earlier work
+or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based on the
+Program.
+
+To "propagate" a work means to do anything with it that, without permission,
+would make you directly or secondarily liable for infringement under applicable
+copyright law, except executing it on a computer or modifying a private copy.
+Propagation includes copying, distribution (with or without modification),
+making available to the public, and in some countries other activities as
+well.
+
+To "convey" a work means any kind of propagation that enables other parties
+to make or receive copies. Mere interaction with a user through a computer
+network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays "Appropriate Legal Notices" to the
+extent that it includes a convenient and prominently visible feature that
+(1) displays an appropriate copyright notice, and (2) tells the user that
+there is no warranty for the work (except to the extent that warranties are
+provided), that licensees may convey the work under this License, and how
+to view a copy of this License. If the interface presents a list of user commands
+or options, such as a menu, a prominent item in the list meets this criterion.
+
+   1. Source Code.
+
+The "source code" for a work means the preferred form of the work for making
+modifications to it. "Object code" means any non-source form of a work.
+
+A "Standard Interface" means an interface that either is an official standard
+defined by a recognized standards body, or, in the case of interfaces specified
+for a particular programming language, one that is widely used among developers
+working in that language.
+
+The "System Libraries" of an executable work include anything, other than
+the work as a whole, that (a) is included in the normal form of packaging
+a Major Component, but which is not part of that Major Component, and (b)
+serves only to enable use of the work with that Major Component, or to implement
+a Standard Interface for which an implementation is available to the public
+in source code form. A "Major Component", in this context, means a major essential
+component (kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to produce
+the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all the source
+code needed to generate, install, and (for an executable work) run the object
+code and to modify the work, including scripts to control those activities.
+However, it does not include the work's System Libraries, or general-purpose
+tools or generally available free programs which are used unmodified in performing
+those activities but which are not part of the work. For example, Corresponding
+Source includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically linked
+subprograms that the work is specifically designed to require, such as by
+intimate data communication or control flow between those subprograms and
+other parts of the work.
+
+The Corresponding Source need not include anything that users can regenerate
+automatically from other parts of the Corresponding Source.
+
+   The Corresponding Source for a work in source code form is that same work.
+
+   2. Basic Permissions.
+
+All rights granted under this License are granted for the term of copyright
+on the Program, and are irrevocable provided the stated conditions are met.
+This License explicitly affirms your unlimited permission to run the unmodified
+Program. The output from running a covered work is covered by this License
+only if the output, given its content, constitutes a covered work. This License
+acknowledges your rights of fair use or other equivalent, as provided by copyright
+law.
+
+You may make, run and propagate covered works that you do not convey, without
+conditions so long as your license otherwise remains in force. You may convey
+covered works to others for the sole purpose of having them make modifications
+exclusively for you, or provide you with facilities for running those works,
+provided that you comply with the terms of this License in conveying all material
+for which you do not control copyright. Those thus making or running the covered
+works for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of your copyrighted
+material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the conditions
+stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
+
+   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological measure
+under any applicable law fulfilling obligations under article 11 of the WIPO
+copyright treaty adopted on 20 December 1996, or similar laws prohibiting
+or restricting circumvention of such measures.
+
+When you convey a covered work, you waive any legal power to forbid circumvention
+of technological measures to the extent such circumvention is effected by
+exercising rights under this License with respect to the covered work, and
+you disclaim any intention to limit operation or modification of the work
+as a means of enforcing, against the work's users, your or third parties'
+legal rights to forbid circumvention of technological measures.
+
+   4. Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you receive
+it, in any medium, provided that you conspicuously and appropriately publish
+on each copy an appropriate copyright notice; keep intact all notices stating
+that this License and any non-permissive terms added in accord with section
+7 apply to the code; keep intact all notices of the absence of any warranty;
+and give all recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey, and you
+may offer support or warranty protection for a fee.
+
+   5. Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to produce
+it from the Program, in the form of source code under the terms of section
+4, provided that you also meet all of these conditions:
+
+a) The work must carry prominent notices stating that you modified it, and
+giving a relevant date.
+
+b) The work must carry prominent notices stating that it is released under
+this License and any conditions added under section 7. This requirement modifies
+the requirement in section 4 to "keep intact all notices".
+
+c) You must license the entire work, as a whole, under this License to anyone
+who comes into possession of a copy. This License will therefore apply, along
+with any applicable section 7 additional terms, to the whole of the work,
+and all its parts, regardless of how they are packaged. This License gives
+no permission to license the work in any other way, but it does not invalidate
+such permission if you have separately received it.
+
+d) If the work has interactive user interfaces, each must display Appropriate
+Legal Notices; however, if the Program has interactive interfaces that do
+not display Appropriate Legal Notices, your work need not make them do so.
+
+A compilation of a covered work with other separate and independent works,
+which are not by their nature extensions of the covered work, and which are
+not combined with it such as to form a larger program, in or on a volume of
+a storage or distribution medium, is called an "aggregate" if the compilation
+and its resulting copyright are not used to limit the access or legal rights
+of the compilation's users beyond what the individual works permit. Inclusion
+of a covered work in an aggregate does not cause this License to apply to
+the other parts of the aggregate.
+
+   6. Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of sections
+4 and 5, provided that you also convey the machine-readable Corresponding
+Source under the terms of this License, in one of these ways:
+
+a) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by the Corresponding Source fixed
+on a durable physical medium customarily used for software interchange.
+
+b) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by a written offer, valid for
+at least three years and valid for as long as you offer spare parts or customer
+support for that product model, to give anyone who possesses the object code
+either (1) a copy of the Corresponding Source for all the software in the
+product that is covered by this License, on a durable physical medium customarily
+used for software interchange, for a price no more than your reasonable cost
+of physically performing this conveying of source, or (2) access to copy the
+Corresponding Source from a network server at no charge.
+
+c) Convey individual copies of the object code with a copy of the written
+offer to provide the Corresponding Source. This alternative is allowed only
+occasionally and noncommercially, and only if you received the object code
+with such an offer, in accord with subsection 6b.
+
+d) Convey the object code by offering access from a designated place (gratis
+or for a charge), and offer equivalent access to the Corresponding Source
+in the same way through the same place at no further charge. You need not
+require recipients to copy the Corresponding Source along with the object
+code. If the place to copy the object code is a network server, the Corresponding
+Source may be on a different server (operated by you or a third party) that
+supports equivalent copying facilities, provided you maintain clear directions
+next to the object code saying where to find the Corresponding Source. Regardless
+of what server hosts the Corresponding Source, you remain obligated to ensure
+that it is available for as long as needed to satisfy these requirements.
+
+e) Convey the object code using peer-to-peer transmission, provided you inform
+other peers where the object code and Corresponding Source of the work are
+being offered to the general public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded from
+the Corresponding Source as a System Library, need not be included in conveying
+the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any tangible
+personal property which is normally used for personal, family, or household
+purposes, or (2) anything designed or sold for incorporation into a dwelling.
+In determining whether a product is a consumer product, doubtful cases shall
+be resolved in favor of coverage. For a particular product received by a particular
+user, "normally used" refers to a typical or common use of that class of product,
+regardless of the status of the particular user or of the way in which the
+particular user actually uses, or expects or is expected to use, the product.
+A product is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent the
+only significant mode of use of the product.
+
+"Installation Information" for a User Product means any methods, procedures,
+authorization keys, or other information required to install and execute modified
+versions of a covered work in that User Product from a modified version of
+its Corresponding Source. The information must suffice to ensure that the
+continued functioning of the modified object code is in no case prevented
+or interfered with solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or specifically
+for use in, a User Product, and the conveying occurs as part of a transaction
+in which the right of possession and use of the User Product is transferred
+to the recipient in perpetuity or for a fixed term (regardless of how the
+transaction is characterized), the Corresponding Source conveyed under this
+section must be accompanied by the Installation Information. But this requirement
+does not apply if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has been installed
+in ROM).
+
+The requirement to provide Installation Information does not include a requirement
+to continue to provide support service, warranty, or updates for a work that
+has been modified or installed by the recipient, or for the User Product in
+which it has been modified or installed. Access to a network may be denied
+when the modification itself materially and adversely affects the operation
+of the network or violates the rules and protocols for communication across
+the network.
+
+Corresponding Source conveyed, and Installation Information provided, in accord
+with this section must be in a format that is publicly documented (and with
+an implementation available to the public in source code form), and must require
+no special password or key for unpacking, reading or copying.
+
+   7. Additional Terms.
+
+"Additional permissions" are terms that supplement the terms of this License
+by making exceptions from one or more of its conditions. Additional permissions
+that are applicable to the entire Program shall be treated as though they
+were included in this License, to the extent that they are valid under applicable
+law. If additional permissions apply only to part of the Program, that part
+may be used separately under those permissions, but the entire Program remains
+governed by this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option remove any
+additional permissions from that copy, or from any part of it. (Additional
+permissions may be written to require their own removal in certain cases when
+you modify the work.) You may place additional permissions on material, added
+by you to a covered work, for which you have or can give appropriate copyright
+permission.
+
+Notwithstanding any other provision of this License, for material you add
+to a covered work, you may (if authorized by the copyright holders of that
+material) supplement the terms of this License with terms:
+
+a) Disclaiming warranty or limiting liability differently from the terms of
+sections 15 and 16 of this License; or
+
+b) Requiring preservation of specified reasonable legal notices or author
+attributions in that material or in the Appropriate Legal Notices displayed
+by works containing it; or
+
+c) Prohibiting misrepresentation of the origin of that material, or requiring
+that modified versions of such material be marked in reasonable ways as different
+from the original version; or
+
+d) Limiting the use for publicity purposes of names of licensors or authors
+of the material; or
+
+e) Declining to grant rights under trademark law for use of some trade names,
+trademarks, or service marks; or
+
+f) Requiring indemnification of licensors and authors of that material by
+anyone who conveys the material (or modified versions of it) with contractual
+assumptions of liability to the recipient, for any liability that these contractual
+assumptions directly impose on those licensors and authors.
+
+All other non-permissive additional terms are considered "further restrictions"
+within the meaning of section 10. If the Program as you received it, or any
+part of it, contains a notice stating that it is governed by this License
+along with a term that is a further restriction, you may remove that term.
+If a license document contains a further restriction but permits relicensing
+or conveying under this License, you may add to a covered work material governed
+by the terms of that license document, provided that the further restriction
+does not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you must place,
+in the relevant source files, a statement of the additional terms that apply
+to those files, or a notice indicating where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the form
+of a separately written license, or stated as exceptions; the above requirements
+apply either way.
+
+   8. Termination.
+
+You may not propagate or modify a covered work except as expressly provided
+under this License. Any attempt otherwise to propagate or modify it is void,
+and will automatically terminate your rights under this License (including
+any patent licenses granted under the third paragraph of section 11).
+
+However, if you cease all violation of this License, then your license from
+a particular copyright holder is reinstated (a) provisionally, unless and
+until the copyright holder explicitly and finally terminates your license,
+and (b) permanently, if the copyright holder fails to notify you of the violation
+by some reasonable means prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is reinstated permanently
+if the copyright holder notifies you of the violation by some reasonable means,
+this is the first time you have received notice of violation of this License
+(for any work) from that copyright holder, and you cure the violation prior
+to 30 days after your receipt of the notice.
+
+Termination of your rights under this section does not terminate the licenses
+of parties who have received copies or rights from you under this License.
+If your rights have been terminated and not permanently reinstated, you do
+not qualify to receive new licenses for the same material under section 10.
+
+   9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run a copy
+of the Program. Ancillary propagation of a covered work occurring solely as
+a consequence of using peer-to-peer transmission to receive a copy likewise
+does not require acceptance. However, nothing other than this License grants
+you permission to propagate or modify any covered work. These actions infringe
+copyright if you do not accept this License. Therefore, by modifying or propagating
+a covered work, you indicate your acceptance of this License to do so.
+
+   10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically receives
+a license from the original licensors, to run, modify and propagate that work,
+subject to this License. You are not responsible for enforcing compliance
+by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an organization,
+or substantially all assets of one, or subdividing an organization, or merging
+organizations. If propagation of a covered work results from an entity transaction,
+each party to that transaction who receives a copy of the work also receives
+whatever licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the Corresponding
+Source of the work from the predecessor in interest, if the predecessor has
+it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the rights
+granted or affirmed under this License. For example, you may not impose a
+license fee, royalty, or other charge for exercise of rights granted under
+this License, and you may not initiate litigation (including a cross-claim
+or counterclaim in a lawsuit) alleging that any patent claim is infringed
+by making, using, selling, offering for sale, or importing the Program or
+any portion of it.
+
+   11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this License
+of the Program or a work on which the Program is based. The work thus licensed
+is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims owned or controlled
+by the contributor, whether already acquired or hereafter acquired, that would
+be infringed by some manner, permitted by this License, of making, using,
+or selling its contributor version, but do not include claims that would be
+infringed only as a consequence of further modification of the contributor
+version. For purposes of this definition, "control" includes the right to
+grant patent sublicenses in a manner consistent with the requirements of this
+License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free patent
+license under the contributor's essential patent claims, to make, use, sell,
+offer for sale, import and otherwise run, modify and propagate the contents
+of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express agreement
+or commitment, however denominated, not to enforce a patent (such as an express
+permission to practice a patent or covenant not to sue for patent infringement).
+To "grant" such a patent license to a party means to make such an agreement
+or commitment not to enforce a patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license, and the
+Corresponding Source of the work is not available for anyone to copy, free
+of charge and under the terms of this License, through a publicly available
+network server or other readily accessible means, then you must either (1)
+cause the Corresponding Source to be so available, or (2) arrange to deprive
+yourself of the benefit of the patent license for this particular work, or
+(3) arrange, in a manner consistent with the requirements of this License,
+to extend the patent license to downstream recipients. "Knowingly relying"
+means you have actual knowledge that, but for the patent license, your conveying
+the covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that country
+that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or arrangement,
+you convey, or propagate by procuring conveyance of, a covered work, and grant
+a patent license to some of the parties receiving the covered work authorizing
+them to use, propagate, modify or convey a specific copy of the covered work,
+then the patent license you grant is automatically extended to all recipients
+of the covered work and works based on it.
+
+A patent license is "discriminatory" if it does not include within the scope
+of its coverage, prohibits the exercise of, or is conditioned on the non-exercise
+of one or more of the rights that are specifically granted under this License.
+You may not convey a covered work if you are a party to an arrangement with
+a third party that is in the business of distributing software, under which
+you make payment to the third party based on the extent of your activity of
+conveying the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by you
+(or copies made from those copies), or (b) primarily for and in connection
+with specific products or compilations that contain the covered work, unless
+you entered into that arrangement, or that patent license was granted, prior
+to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting any implied
+license or other defenses to infringement that may otherwise be available
+to you under applicable patent law.
+
+   12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or otherwise)
+that contradict the conditions of this License, they do not excuse you from
+the conditions of this License. If you cannot convey a covered work so as
+to satisfy simultaneously your obligations under this License and any other
+pertinent obligations, then as a consequence you may not convey it at all.
+For example, if you agree to terms that obligate you to collect a royalty
+for further conveying from those to whom you convey the Program, the only
+way you could satisfy both those terms and this License would be to refrain
+entirely from conveying the Program.
+
+   13. Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have permission to
+link or combine any covered work with a work licensed under version 3 of the
+GNU Affero General Public License into a single combined work, and to convey
+the resulting work. The terms of this License will continue to apply to the
+part which is the covered work, but the special requirements of the GNU Affero
+General Public License, section 13, concerning interaction through a network
+will apply to the combination as such.
+
+   14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions of the
+GNU General Public License from time to time. Such new versions will be similar
+in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies
+that a certain numbered version of the GNU General Public License "or any
+later version" applies to it, you have the option of following the terms and
+conditions either of that numbered version or of any later version published
+by the Free Software Foundation. If the Program does not specify a version
+number of the GNU General Public License, you may choose any version ever
+published by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions of
+the GNU General Public License can be used, that proxy's public statement
+of acceptance of a version permanently authorizes you to choose that version
+for the Program.
+
+Later license versions may give you additional or different permissions. However,
+no additional obligations are imposed on any author or copyright holder as
+a result of your choosing to follow a later version.
+
+   15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
+LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
+OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
+PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+   16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
+ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM
+AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
+USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
+PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+   17. Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided above cannot
+be given local legal effect according to their terms, reviewing courts shall
+apply local law that most closely approximates an absolute waiver of all civil
+liability in connection with the Program, unless a warranty or assumption
+of liability accompanies a copy of the Program in return for a fee. END OF
+TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible
+use to the public, the best way to achieve this is to make it free software
+which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach
+them to the start of each source file to most effectively state the exclusion
+of warranty; and each file should have at least the "copyright" line and a
+pointer to where the full notice is found.
+
+<one line to give the program's name and a brief idea of what it does.>
+
+Copyright (C) <year> <name of author>
+
+This program is free software: you can redistribute it and/or modify it under
+the terms of the GNU General Public License as published by the Free Software
+Foundation, either version 3 of the License, or (at your option) any later
+version.
+
+This program is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
+FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
+
+You should have received a copy of the GNU General Public License along with
+this program. If not, see <http s ://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program does terminal interaction, make it output a short notice like
+this when it starts in an interactive mode:
+
+<program> Copyright (C) <year> <name of author>
+
+This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+
+This is free software, and you are welcome to redistribute it under certain
+conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands might
+be different; for a GUI interface, you would use an "about box".
+
+You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary. For
+more information on this, and how to apply and follow the GNU GPL, see <http
+s ://www.gnu.org/licenses/>.
+
+The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General Public
+License instead of this License. But first, please read <http s ://www.gnu.org/
+licenses /why-not-lgpl.html>.

+GNU GENERAL PUBLIC LICENSE
+
+Version 3, 29 June 2007
+
+Copyright © 2007 Free Software Foundation, Inc. <http s ://fsf.org/>
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The GNU General Public License is a free, copyleft license for software and
+other kinds of works.
+
+The licenses for most software and other practical works are designed to take
+away your freedom to share and change the works. By contrast, the GNU General
+Public License is intended to guarantee your freedom to share and change all
+versions of a program--to make sure it remains free software for all its users.
+We, the Free Software Foundation, use the GNU General Public License for most
+of our software; it applies also to any other work released this way by its
+authors. You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for them if you wish), that
+you receive source code or can get it if you want it, that you can change
+the software or use pieces of it in new free programs, and that you know you
+can do these things.
+
+To protect your rights, we need to prevent others from denying you these rights
+or asking you to surrender the rights. Therefore, you have certain responsibilities
+if you distribute copies of the software, or if you modify it: responsibilities
+to respect the freedom of others.
+
+For example, if you distribute copies of such a program, whether gratis or
+for a fee, you must pass on to the recipients the same freedoms that you received.
+You must make sure that they, too, receive or can get the source code. And
+you must show them these terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps: (1) assert
+copyright on the software, and (2) offer you this License giving you legal
+permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains that
+there is no warranty for this free software. For both users' and authors'
+sake, the GPL requires that modified versions be marked as changed, so that
+their problems will not be attributed erroneously to authors of previous versions.
+
+Some devices are designed to deny users access to install or run modified
+versions of the software inside them, although the manufacturer can do so.
+This is fundamentally incompatible with the aim of protecting users' freedom
+to change the software. The systematic pattern of such abuse occurs in the
+area of products for individuals to use, which is precisely where it is most
+unacceptable. Therefore, we have designed this version of the GPL to prohibit
+the practice for those products. If such problems arise substantially in other
+domains, we stand ready to extend this provision to those domains in future
+versions of the GPL, as needed to protect the freedom of users.
+
+Finally, every program is threatened constantly by software patents. States
+should not allow patents to restrict development and use of software on general-purpose
+computers, but in those that do, we wish to avoid the special danger that
+patents applied to a free program could make it effectively proprietary. To
+prevent this, the GPL assures that patents cannot be used to render the program
+non-free.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+TERMS AND CONDITIONS
+
+   0. Definitions.
+
+   "This License" refers to version 3 of the GNU General Public License.
+
+"Copyright" also means copyright-like laws that apply to other kinds of works,
+such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this License.
+Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals
+or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work in
+a fashion requiring copyright permission, other than the making of an exact
+copy. The resulting work is called a "modified version" of the earlier work
+or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based on the
+Program.
+
+To "propagate" a work means to do anything with it that, without permission,
+would make you directly or secondarily liable for infringement under applicable
+copyright law, except executing it on a computer or modifying a private copy.
+Propagation includes copying, distribution (with or without modification),
+making available to the public, and in some countries other activities as
+well.
+
+To "convey" a work means any kind of propagation that enables other parties
+to make or receive copies. Mere interaction with a user through a computer
+network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays "Appropriate Legal Notices" to the
+extent that it includes a convenient and prominently visible feature that
+(1) displays an appropriate copyright notice, and (2) tells the user that
+there is no warranty for the work (except to the extent that warranties are
+provided), that licensees may convey the work under this License, and how
+to view a copy of this License. If the interface presents a list of user commands
+or options, such as a menu, a prominent item in the list meets this criterion.
+
+   1. Source Code.
+
+The "source code" for a work means the preferred form of the work for making
+modifications to it. "Object code" means any non-source form of a work.
+
+A "Standard Interface" means an interface that either is an official standard
+defined by a recognized standards body, or, in the case of interfaces specified
+for a particular programming language, one that is widely used among developers
+working in that language.
+
+The "System Libraries" of an executable work include anything, other than
+the work as a whole, that (a) is included in the normal form of packaging
+a Major Component, but which is not part of that Major Component, and (b)
+serves only to enable use of the work with that Major Component, or to implement
+a Standard Interface for which an implementation is available to the public
+in source code form. A "Major Component", in this context, means a major essential
+component (kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to produce
+the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all the source
+code needed to generate, install, and (for an executable work) run the object
+code and to modify the work, including scripts to control those activities.
+However, it does not include the work's System Libraries, or general-purpose
+tools or generally available free programs which are used unmodified in performing
+those activities but which are not part of the work. For example, Corresponding
+Source includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically linked
+subprograms that the work is specifically designed to require, such as by
+intimate data communication or control flow between those subprograms and
+other parts of the work.
+
+The Corresponding Source need not include anything that users can regenerate
+automatically from other parts of the Corresponding Source.
+
+   The Corresponding Source for a work in source code form is that same work.
+
+   2. Basic Permissions.
+
+All rights granted under this License are granted for the term of copyright
+on the Program, and are irrevocable provided the stated conditions are met.
+This License explicitly affirms your unlimited permission to run the unmodified
+Program. The output from running a covered work is covered by this License
+only if the output, given its content, constitutes a covered work. This License
+acknowledges your rights of fair use or other equivalent, as provided by copyright
+law.
+
+You may make, run and propagate covered works that you do not convey, without
+conditions so long as your license otherwise remains in force. You may convey
+covered works to others for the sole purpose of having them make modifications
+exclusively for you, or provide you with facilities for running those works,
+provided that you comply with the terms of this License in conveying all material
+for which you do not control copyright. Those thus making or running the covered
+works for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of your copyrighted
+material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the conditions
+stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
+
+   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological measure
+under any applicable law fulfilling obligations under article 11 of the WIPO
+copyright treaty adopted on 20 December 1996, or similar laws prohibiting
+or restricting circumvention of such measures.
+
+When you convey a covered work, you waive any legal power to forbid circumvention
+of technological measures to the extent such circumvention is effected by
+exercising rights under this License with respect to the covered work, and
+you disclaim any intention to limit operation or modification of the work
+as a means of enforcing, against the work's users, your or third parties'
+legal rights to forbid circumvention of technological measures.
+
+   4. Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you receive
+it, in any medium, provided that you conspicuously and appropriately publish
+on each copy an appropriate copyright notice; keep intact all notices stating
+that this License and any non-permissive terms added in accord with section
+7 apply to the code; keep intact all notices of the absence of any warranty;
+and give all recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey, and you
+may offer support or warranty protection for a fee.
+
+   5. Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to produce
+it from the Program, in the form of source code under the terms of section
+4, provided that you also meet all of these conditions:
+
+a) The work must carry prominent notices stating that you modified it, and
+giving a relevant date.
+
+b) The work must carry prominent notices stating that it is released under
+this License and any conditions added under section 7. This requirement modifies
+the requirement in section 4 to "keep intact all notices".
+
+c) You must license the entire work, as a whole, under this License to anyone
+who comes into possession of a copy. This License will therefore apply, along
+with any applicable section 7 additional terms, to the whole of the work,
+and all its parts, regardless of how they are packaged. This License gives
+no permission to license the work in any other way, but it does not invalidate
+such permission if you have separately received it.
+
+d) If the work has interactive user interfaces, each must display Appropriate
+Legal Notices; however, if the Program has interactive interfaces that do
+not display Appropriate Legal Notices, your work need not make them do so.
+
+A compilation of a covered work with other separate and independent works,
+which are not by their nature extensions of the covered work, and which are
+not combined with it such as to form a larger program, in or on a volume of
+a storage or distribution medium, is called an "aggregate" if the compilation
+and its resulting copyright are not used to limit the access or legal rights
+of the compilation's users beyond what the individual works permit. Inclusion
+of a covered work in an aggregate does not cause this License to apply to
+the other parts of the aggregate.
+
+   6. Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of sections
+4 and 5, provided that you also convey the machine-readable Corresponding
+Source under the terms of this License, in one of these ways:
+
+a) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by the Corresponding Source fixed
+on a durable physical medium customarily used for software interchange.
+
+b) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by a written offer, valid for
+at least three years and valid for as long as you offer spare parts or customer
+support for that product model, to give anyone who possesses the object code
+either (1) a copy of the Corresponding Source for all the software in the
+product that is covered by this License, on a durable physical medium customarily
+used for software interchange, for a price no more than your reasonable cost
+of physically performing this conveying of source, or (2) access to copy the
+Corresponding Source from a network server at no charge.
+
+c) Convey individual copies of the object code with a copy of the written
+offer to provide the Corresponding Source. This alternative is allowed only
+occasionally and noncommercially, and only if you received the object code
+with such an offer, in accord with subsection 6b.
+
+d) Convey the object code by offering access from a designated place (gratis
+or for a charge), and offer equivalent access to the Corresponding Source
+in the same way through the same place at no further charge. You need not
+require recipients to copy the Corresponding Source along with the object
+code. If the place to copy the object code is a network server, the Corresponding
+Source may be on a different server (operated by you or a third party) that
+supports equivalent copying facilities, provided you maintain clear directions
+next to the object code saying where to find the Corresponding Source. Regardless
+of what server hosts the Corresponding Source, you remain obligated to ensure
+that it is available for as long as needed to satisfy these requirements.
+
+e) Convey the object code using peer-to-peer transmission, provided you inform
+other peers where the object code and Corresponding Source of the work are
+being offered to the general public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded from
+the Corresponding Source as a System Library, need not be included in conveying
+the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any tangible
+personal property which is normally used for personal, family, or household
+purposes, or (2) anything designed or sold for incorporation into a dwelling.
+In determining whether a product is a consumer product, doubtful cases shall
+be resolved in favor of coverage. For a particular product received by a particular
+user, "normally used" refers to a typical or common use of that class of product,
+regardless of the status of the particular user or of the way in which the
+particular user actually uses, or expects or is expected to use, the product.
+A product is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent the
+only significant mode of use of the product.
+
+"Installation Information" for a User Product means any methods, procedures,
+authorization keys, or other information required to install and execute modified
+versions of a covered work in that User Product from a modified version of
+its Corresponding Source. The information must suffice to ensure that the
+continued functioning of the modified object code is in no case prevented
+or interfered with solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or specifically
+for use in, a User Product, and the conveying occurs as part of a transaction
+in which the right of possession and use of the User Product is transferred
+to the recipient in perpetuity or for a fixed term (regardless of how the
+transaction is characterized), the Corresponding Source conveyed under this
+section must be accompanied by the Installation Information. But this requirement
+does not apply if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has been installed
+in ROM).
+
+The requirement to provide Installation Information does not include a requirement
+to continue to provide support service, warranty, or updates for a work that
+has been modified or installed by the recipient, or for the User Product in
+which it has been modified or installed. Access to a network may be denied
+when the modification itself materially and adversely affects the operation
+of the network or violates the rules and protocols for communication across
+the network.
+
+Corresponding Source conveyed, and Installation Information provided, in accord
+with this section must be in a format that is publicly documented (and with
+an implementation available to the public in source code form), and must require
+no special password or key for unpacking, reading or copying.
+
+   7. Additional Terms.
+
+"Additional permissions" are terms that supplement the terms of this License
+by making exceptions from one or more of its conditions. Additional permissions
+that are applicable to the entire Program shall be treated as though they
+were included in this License, to the extent that they are valid under applicable
+law. If additional permissions apply only to part of the Program, that part
+may be used separately under those permissions, but the entire Program remains
+governed by this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option remove any
+additional permissions from that copy, or from any part of it. (Additional
+permissions may be written to require their own removal in certain cases when
+you modify the work.) You may place additional permissions on material, added
+by you to a covered work, for which you have or can give appropriate copyright
+permission.
+
+Notwithstanding any other provision of this License, for material you add
+to a covered work, you may (if authorized by the copyright holders of that
+material) supplement the terms of this License with terms:
+
+a) Disclaiming warranty or limiting liability differently from the terms of
+sections 15 and 16 of this License; or
+
+b) Requiring preservation of specified reasonable legal notices or author
+attributions in that material or in the Appropriate Legal Notices displayed
+by works containing it; or
+
+c) Prohibiting misrepresentation of the origin of that material, or requiring
+that modified versions of such material be marked in reasonable ways as different
+from the original version; or
+
+d) Limiting the use for publicity purposes of names of licensors or authors
+of the material; or
+
+e) Declining to grant rights under trademark law for use of some trade names,
+trademarks, or service marks; or
+
+f) Requiring indemnification of licensors and authors of that material by
+anyone who conveys the material (or modified versions of it) with contractual
+assumptions of liability to the recipient, for any liability that these contractual
+assumptions directly impose on those licensors and authors.
+
+All other non-permissive additional terms are considered "further restrictions"
+within the meaning of section 10. If the Program as you received it, or any
+part of it, contains a notice stating that it is governed by this License
+along with a term that is a further restriction, you may remove that term.
+If a license document contains a further restriction but permits relicensing
+or conveying under this License, you may add to a covered work material governed
+by the terms of that license document, provided that the further restriction
+does not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you must place,
+in the relevant source files, a statement of the additional terms that apply
+to those files, or a notice indicating where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the form
+of a separately written license, or stated as exceptions; the above requirements
+apply either way.
+
+   8. Termination.
+
+You may not propagate or modify a covered work except as expressly provided
+under this License. Any attempt otherwise to propagate or modify it is void,
+and will automatically terminate your rights under this License (including
+any patent licenses granted under the third paragraph of section 11).
+
+However, if you cease all violation of this License, then your license from
+a particular copyright holder is reinstated (a) provisionally, unless and
+until the copyright holder explicitly and finally terminates your license,
+and (b) permanently, if the copyright holder fails to notify you of the violation
+by some reasonable means prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is reinstated permanently
+if the copyright holder notifies you of the violation by some reasonable means,
+this is the first time you have received notice of violation of this License
+(for any work) from that copyright holder, and you cure the violation prior
+to 30 days after your receipt of the notice.
+
+Termination of your rights under this section does not terminate the licenses
+of parties who have received copies or rights from you under this License.
+If your rights have been terminated and not permanently reinstated, you do
+not qualify to receive new licenses for the same material under section 10.
+
+   9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run a copy
+of the Program. Ancillary propagation of a covered work occurring solely as
+a consequence of using peer-to-peer transmission to receive a copy likewise
+does not require acceptance. However, nothing other than this License grants
+you permission to propagate or modify any covered work. These actions infringe
+copyright if you do not accept this License. Therefore, by modifying or propagating
+a covered work, you indicate your acceptance of this License to do so.
+
+   10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically receives
+a license from the original licensors, to run, modify and propagate that work,
+subject to this License. You are not responsible for enforcing compliance
+by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an organization,
+or substantially all assets of one, or subdividing an organization, or merging
+organizations. If propagation of a covered work results from an entity transaction,
+each party to that transaction who receives a copy of the work also receives
+whatever licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the Corresponding
+Source of the work from the predecessor in interest, if the predecessor has
+it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the rights
+granted or affirmed under this License. For example, you may not impose a
+license fee, royalty, or other charge for exercise of rights granted under
+this License, and you may not initiate litigation (including a cross-claim
+or counterclaim in a lawsuit) alleging that any patent claim is infringed
+by making, using, selling, offering for sale, or importing the Program or
+any portion of it.
+
+   11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this License
+of the Program or a work on which the Program is based. The work thus licensed
+is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims owned or controlled
+by the contributor, whether already acquired or hereafter acquired, that would
+be infringed by some manner, permitted by this License, of making, using,
+or selling its contributor version, but do not include claims that would be
+infringed only as a consequence of further modification of the contributor
+version. For purposes of this definition, "control" includes the right to
+grant patent sublicenses in a manner consistent with the requirements of this
+License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free patent
+license under the contributor's essential patent claims, to make, use, sell,
+offer for sale, import and otherwise run, modify and propagate the contents
+of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express agreement
+or commitment, however denominated, not to enforce a patent (such as an express
+permission to practice a patent or covenant not to sue for patent infringement).
+To "grant" such a patent license to a party means to make such an agreement
+or commitment not to enforce a patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license, and the
+Corresponding Source of the work is not available for anyone to copy, free
+of charge and under the terms of this License, through a publicly available
+network server or other readily accessible means, then you must either (1)
+cause the Corresponding Source to be so available, or (2) arrange to deprive
+yourself of the benefit of the patent license for this particular work, or
+(3) arrange, in a manner consistent with the requirements of this License,
+to extend the patent license to downstream recipients. "Knowingly relying"
+means you have actual knowledge that, but for the patent license, your conveying
+the covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that country
+that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or arrangement,
+you convey, or propagate by procuring conveyance of, a covered work, and grant
+a patent license to some of the parties receiving the covered work authorizing
+them to use, propagate, modify or convey a specific copy of the covered work,
+then the patent license you grant is automatically extended to all recipients
+of the covered work and works based on it.
+
+A patent license is "discriminatory" if it does not include within the scope
+of its coverage, prohibits the exercise of, or is conditioned on the non-exercise
+of one or more of the rights that are specifically granted under this License.
+You may not convey a covered work if you are a party to an arrangement with
+a third party that is in the business of distributing software, under which
+you make payment to the third party based on the extent of your activity of
+conveying the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by you
+(or copies made from those copies), or (b) primarily for and in connection
+with specific products or compilations that contain the covered work, unless
+you entered into that arrangement, or that patent license was granted, prior
+to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting any implied
+license or other defenses to infringement that may otherwise be available
+to you under applicable patent law.
+
+   12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or otherwise)
+that contradict the conditions of this License, they do not excuse you from
+the conditions of this License. If you cannot convey a covered work so as
+to satisfy simultaneously your obligations under this License and any other
+pertinent obligations, then as a consequence you may not convey it at all.
+For example, if you agree to terms that obligate you to collect a royalty
+for further conveying from those to whom you convey the Program, the only
+way you could satisfy both those terms and this License would be to refrain
+entirely from conveying the Program.
+
+   13. Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have permission to
+link or combine any covered work with a work licensed under version 3 of the
+GNU Affero General Public License into a single combined work, and to convey
+the resulting work. The terms of this License will continue to apply to the
+part which is the covered work, but the special requirements of the GNU Affero
+General Public License, section 13, concerning interaction through a network
+will apply to the combination as such.
+
+   14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions of the
+GNU General Public License from time to time. Such new versions will be similar
+in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies
+that a certain numbered version of the GNU General Public License "or any
+later version" applies to it, you have the option of following the terms and
+conditions either of that numbered version or of any later version published
+by the Free Software Foundation. If the Program does not specify a version
+number of the GNU General Public License, you may choose any version ever
+published by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions of
+the GNU General Public License can be used, that proxy's public statement
+of acceptance of a version permanently authorizes you to choose that version
+for the Program.
+
+Later license versions may give you additional or different permissions. However,
+no additional obligations are imposed on any author or copyright holder as
+a result of your choosing to follow a later version.
+
+   15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
+LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
+OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
+PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+   16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
+ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM
+AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
+USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
+PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+   17. Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided above cannot
+be given local legal effect according to their terms, reviewing courts shall
+apply local law that most closely approximates an absolute waiver of all civil
+liability in connection with the Program, unless a warranty or assumption
+of liability accompanies a copy of the Program in return for a fee. END OF
+TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible
+use to the public, the best way to achieve this is to make it free software
+which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach
+them to the start of each source file to most effectively state the exclusion
+of warranty; and each file should have at least the "copyright" line and a
+pointer to where the full notice is found.
+
+<one line to give the program's name and a brief idea of what it does.>
+
+Copyright (C) <year> <name of author>
+
+This program is free software: you can redistribute it and/or modify it under
+the terms of the GNU General Public License as published by the Free Software
+Foundation, either version 3 of the License, or (at your option) any later
+version.
+
+This program is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
+FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
+
+You should have received a copy of the GNU General Public License along with
+this program. If not, see <http s ://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program does terminal interaction, make it output a short notice like
+this when it starts in an interactive mode:
+
+<program> Copyright (C) <year> <name of author>
+
+This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+
+This is free software, and you are welcome to redistribute it under certain
+conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands might
+be different; for a GUI interface, you would use an "about box".
+
+You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary. For
+more information on this, and how to apply and follow the GNU GPL, see <http
+s ://www.gnu.org/licenses/>.
+
+The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General Public
+License instead of this License. But first, please read <http s ://www.gnu.org/
+licenses /why-not-lgpl.html>.

+GNU GENERAL PUBLIC LICENSE
+
+Version 3, 29 June 2007
+
+Copyright © 2007 Free Software Foundation, Inc. <http s ://fsf.org/>
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The GNU General Public License is a free, copyleft license for software and
+other kinds of works.
+
+The licenses for most software and other practical works are designed to take
+away your freedom to share and change the works. By contrast, the GNU General
+Public License is intended to guarantee your freedom to share and change all
+versions of a program--to make sure it remains free software for all its users.
+We, the Free Software Foundation, use the GNU General Public License for most
+of our software; it applies also to any other work released this way by its
+authors. You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for them if you wish), that
+you receive source code or can get it if you want it, that you can change
+the software or use pieces of it in new free programs, and that you know you
+can do these things.
+
+To protect your rights, we need to prevent others from denying you these rights
+or asking you to surrender the rights. Therefore, you have certain responsibilities
+if you distribute copies of the software, or if you modify it: responsibilities
+to respect the freedom of others.
+
+For example, if you distribute copies of such a program, whether gratis or
+for a fee, you must pass on to the recipients the same freedoms that you received.
+You must make sure that they, too, receive or can get the source code. And
+you must show them these terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps: (1) assert
+copyright on the software, and (2) offer you this License giving you legal
+permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains that
+there is no warranty for this free software. For both users' and authors'
+sake, the GPL requires that modified versions be marked as changed, so that
+their problems will not be attributed erroneously to authors of previous versions.
+
+Some devices are designed to deny users access to install or run modified
+versions of the software inside them, although the manufacturer can do so.
+This is fundamentally incompatible with the aim of protecting users' freedom
+to change the software. The systematic pattern of such abuse occurs in the
+area of products for individuals to use, which is precisely where it is most
+unacceptable. Therefore, we have designed this version of the GPL to prohibit
+the practice for those products. If such problems arise substantially in other
+domains, we stand ready to extend this provision to those domains in future
+versions of the GPL, as needed to protect the freedom of users.
+
+Finally, every program is threatened constantly by software patents. States
+should not allow patents to restrict development and use of software on general-purpose
+computers, but in those that do, we wish to avoid the special danger that
+patents applied to a free program could make it effectively proprietary. To
+prevent this, the GPL assures that patents cannot be used to render the program
+non-free.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+TERMS AND CONDITIONS
+
+   0. Definitions.
+
+   "This License" refers to version 3 of the GNU General Public License.
+
+"Copyright" also means copyright-like laws that apply to other kinds of works,
+such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this License.
+Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals
+or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work in
+a fashion requiring copyright permission, other than the making of an exact
+copy. The resulting work is called a "modified version" of the earlier work
+or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based on the
+Program.
+
+To "propagate" a work means to do anything with it that, without permission,
+would make you directly or secondarily liable for infringement under applicable
+copyright law, except executing it on a computer or modifying a private copy.
+Propagation includes copying, distribution (with or without modification),
+making available to the public, and in some countries other activities as
+well.
+
+To "convey" a work means any kind of propagation that enables other parties
+to make or receive copies. Mere interaction with a user through a computer
+network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays "Appropriate Legal Notices" to the
+extent that it includes a convenient and prominently visible feature that
+(1) displays an appropriate copyright notice, and (2) tells the user that
+there is no warranty for the work (except to the extent that warranties are
+provided), that licensees may convey the work under this License, and how
+to view a copy of this License. If the interface presents a list of user commands
+or options, such as a menu, a prominent item in the list meets this criterion.
+
+   1. Source Code.
+
+The "source code" for a work means the preferred form of the work for making
+modifications to it. "Object code" means any non-source form of a work.
+
+A "Standard Interface" means an interface that either is an official standard
+defined by a recognized standards body, or, in the case of interfaces specified
+for a particular programming language, one that is widely used among developers
+working in that language.
+
+The "System Libraries" of an executable work include anything, other than
+the work as a whole, that (a) is included in the normal form of packaging
+a Major Component, but which is not part of that Major Component, and (b)
+serves only to enable use of the work with that Major Component, or to implement
+a Standard Interface for which an implementation is available to the public
+in source code form. A "Major Component", in this context, means a major essential
+component (kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to produce
+the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all the source
+code needed to generate, install, and (for an executable work) run the object
+code and to modify the work, including scripts to control those activities.
+However, it does not include the work's System Libraries, or general-purpose
+tools or generally available free programs which are used unmodified in performing
+those activities but which are not part of the work. For example, Corresponding
+Source includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically linked
+subprograms that the work is specifically designed to require, such as by
+intimate data communication or control flow between those subprograms and
+other parts of the work.
+
+The Corresponding Source need not include anything that users can regenerate
+automatically from other parts of the Corresponding Source.
+
+   The Corresponding Source for a work in source code form is that same work.
+
+   2. Basic Permissions.
+
+All rights granted under this License are granted for the term of copyright
+on the Program, and are irrevocable provided the stated conditions are met.
+This License explicitly affirms your unlimited permission to run the unmodified
+Program. The output from running a covered work is covered by this License
+only if the output, given its content, constitutes a covered work. This License
+acknowledges your rights of fair use or other equivalent, as provided by copyright
+law.
+
+You may make, run and propagate covered works that you do not convey, without
+conditions so long as your license otherwise remains in force. You may convey
+covered works to others for the sole purpose of having them make modifications
+exclusively for you, or provide you with facilities for running those works,
+provided that you comply with the terms of this License in conveying all material
+for which you do not control copyright. Those thus making or running the covered
+works for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of your copyrighted
+material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the conditions
+stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
+
+   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological measure
+under any applicable law fulfilling obligations under article 11 of the WIPO
+copyright treaty adopted on 20 December 1996, or similar laws prohibiting
+or restricting circumvention of such measures.
+
+When you convey a covered work, you waive any legal power to forbid circumvention
+of technological measures to the extent such circumvention is effected by
+exercising rights under this License with respect to the covered work, and
+you disclaim any intention to limit operation or modification of the work
+as a means of enforcing, against the work's users, your or third parties'
+legal rights to forbid circumvention of technological measures.
+
+   4. Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you receive
+it, in any medium, provided that you conspicuously and appropriately publish
+on each copy an appropriate copyright notice; keep intact all notices stating
+that this License and any non-permissive terms added in accord with section
+7 apply to the code; keep intact all notices of the absence of any warranty;
+and give all recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey, and you
+may offer support or warranty protection for a fee.
+
+   5. Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to produce
+it from the Program, in the form of source code under the terms of section
+4, provided that you also meet all of these conditions:
+
+a) The work must carry prominent notices stating that you modified it, and
+giving a relevant date.
+
+b) The work must carry prominent notices stating that it is released under
+this License and any conditions added under section 7. This requirement modifies
+the requirement in section 4 to "keep intact all notices".
+
+c) You must license the entire work, as a whole, under this License to anyone
+who comes into possession of a copy. This License will therefore apply, along
+with any applicable section 7 additional terms, to the whole of the work,
+and all its parts, regardless of how they are packaged. This License gives
+no permission to license the work in any other way, but it does not invalidate
+such permission if you have separately received it.
+
+d) If the work has interactive user interfaces, each must display Appropriate
+Legal Notices; however, if the Program has interactive interfaces that do
+not display Appropriate Legal Notices, your work need not make them do so.
+
+A compilation of a covered work with other separate and independent works,
+which are not by their nature extensions of the covered work, and which are
+not combined with it such as to form a larger program, in or on a volume of
+a storage or distribution medium, is called an "aggregate" if the compilation
+and its resulting copyright are not used to limit the access or legal rights
+of the compilation's users beyond what the individual works permit. Inclusion
+of a covered work in an aggregate does not cause this License to apply to
+the other parts of the aggregate.
+
+   6. Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of sections
+4 and 5, provided that you also convey the machine-readable Corresponding
+Source under the terms of this License, in one of these ways:
+
+a) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by the Corresponding Source fixed
+on a durable physical medium customarily used for software interchange.
+
+b) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by a written offer, valid for
+at least three years and valid for as long as you offer spare parts or customer
+support for that product model, to give anyone who possesses the object code
+either (1) a copy of the Corresponding Source for all the software in the
+product that is covered by this License, on a durable physical medium customarily
+used for software interchange, for a price no more than your reasonable cost
+of physically performing this conveying of source, or (2) access to copy the
+Corresponding Source from a network server at no charge.
+
+c) Convey individual copies of the object code with a copy of the written
+offer to provide the Corresponding Source. This alternative is allowed only
+occasionally and noncommercially, and only if you received the object code
+with such an offer, in accord with subsection 6b.
+
+d) Convey the object code by offering access from a designated place (gratis
+or for a charge), and offer equivalent access to the Corresponding Source
+in the same way through the same place at no further charge. You need not
+require recipients to copy the Corresponding Source along with the object
+code. If the place to copy the object code is a network server, the Corresponding
+Source may be on a different server (operated by you or a third party) that
+supports equivalent copying facilities, provided you maintain clear directions
+next to the object code saying where to find the Corresponding Source. Regardless
+of what server hosts the Corresponding Source, you remain obligated to ensure
+that it is available for as long as needed to satisfy these requirements.
+
+e) Convey the object code using peer-to-peer transmission, provided you inform
+other peers where the object code and Corresponding Source of the work are
+being offered to the general public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded from
+the Corresponding Source as a System Library, need not be included in conveying
+the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any tangible
+personal property which is normally used for personal, family, or household
+purposes, or (2) anything designed or sold for incorporation into a dwelling.
+In determining whether a product is a consumer product, doubtful cases shall
+be resolved in favor of coverage. For a particular product received by a particular
+user, "normally used" refers to a typical or common use of that class of product,
+regardless of the status of the particular user or of the way in which the
+particular user actually uses, or expects or is expected to use, the product.
+A product is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent the
+only significant mode of use of the product.
+
+"Installation Information" for a User Product means any methods, procedures,
+authorization keys, or other information required to install and execute modified
+versions of a covered work in that User Product from a modified version of
+its Corresponding Source. The information must suffice to ensure that the
+continued functioning of the modified object code is in no case prevented
+or interfered with solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or specifically
+for use in, a User Product, and the conveying occurs as part of a transaction
+in which the right of possession and use of the User Product is transferred
+to the recipient in perpetuity or for a fixed term (regardless of how the
+transaction is characterized), the Corresponding Source conveyed under this
+section must be accompanied by the Installation Information. But this requirement
+does not apply if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has been installed
+in ROM).
+
+The requirement to provide Installation Information does not include a requirement
+to continue to provide support service, warranty, or updates for a work that
+has been modified or installed by the recipient, or for the User Product in
+which it has been modified or installed. Access to a network may be denied
+when the modification itself materially and adversely affects the operation
+of the network or violates the rules and protocols for communication across
+the network.
+
+Corresponding Source conveyed, and Installation Information provided, in accord
+with this section must be in a format that is publicly documented (and with
+an implementation available to the public in source code form), and must require
+no special password or key for unpacking, reading or copying.
+
+   7. Additional Terms.
+
+"Additional permissions" are terms that supplement the terms of this License
+by making exceptions from one or more of its conditions. Additional permissions
+that are applicable to the entire Program shall be treated as though they
+were included in this License, to the extent that they are valid under applicable
+law. If additional permissions apply only to part of the Program, that part
+may be used separately under those permissions, but the entire Program remains
+governed by this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option remove any
+additional permissions from that copy, or from any part of it. (Additional
+permissions may be written to require their own removal in certain cases when
+you modify the work.) You may place additional permissions on material, added
+by you to a covered work, for which you have or can give appropriate copyright
+permission.
+
+Notwithstanding any other provision of this License, for material you add
+to a covered work, you may (if authorized by the copyright holders of that
+material) supplement the terms of this License with terms:
+
+a) Disclaiming warranty or limiting liability differently from the terms of
+sections 15 and 16 of this License; or
+
+b) Requiring preservation of specified reasonable legal notices or author
+attributions in that material or in the Appropriate Legal Notices displayed
+by works containing it; or
+
+c) Prohibiting misrepresentation of the origin of that material, or requiring
+that modified versions of such material be marked in reasonable ways as different
+from the original version; or
+
+d) Limiting the use for publicity purposes of names of licensors or authors
+of the material; or
+
+e) Declining to grant rights under trademark law for use of some trade names,
+trademarks, or service marks; or
+
+f) Requiring indemnification of licensors and authors of that material by
+anyone who conveys the material (or modified versions of it) with contractual
+assumptions of liability to the recipient, for any liability that these contractual
+assumptions directly impose on those licensors and authors.
+
+All other non-permissive additional terms are considered "further restrictions"
+within the meaning of section 10. If the Program as you received it, or any
+part of it, contains a notice stating that it is governed by this License
+along with a term that is a further restriction, you may remove that term.
+If a license document contains a further restriction but permits relicensing
+or conveying under this License, you may add to a covered work material governed
+by the terms of that license document, provided that the further restriction
+does not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you must place,
+in the relevant source files, a statement of the additional terms that apply
+to those files, or a notice indicating where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the form
+of a separately written license, or stated as exceptions; the above requirements
+apply either way.
+
+   8. Termination.
+
+You may not propagate or modify a covered work except as expressly provided
+under this License. Any attempt otherwise to propagate or modify it is void,
+and will automatically terminate your rights under this License (including
+any patent licenses granted under the third paragraph of section 11).
+
+However, if you cease all violation of this License, then your license from
+a particular copyright holder is reinstated (a) provisionally, unless and
+until the copyright holder explicitly and finally terminates your license,
+and (b) permanently, if the copyright holder fails to notify you of the violation
+by some reasonable means prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is reinstated permanently
+if the copyright holder notifies you of the violation by some reasonable means,
+this is the first time you have received notice of violation of this License
+(for any work) from that copyright holder, and you cure the violation prior
+to 30 days after your receipt of the notice.
+
+Termination of your rights under this section does not terminate the licenses
+of parties who have received copies or rights from you under this License.
+If your rights have been terminated and not permanently reinstated, you do
+not qualify to receive new licenses for the same material under section 10.
+
+   9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run a copy
+of the Program. Ancillary propagation of a covered work occurring solely as
+a consequence of using peer-to-peer transmission to receive a copy likewise
+does not require acceptance. However, nothing other than this License grants
+you permission to propagate or modify any covered work. These actions infringe
+copyright if you do not accept this License. Therefore, by modifying or propagating
+a covered work, you indicate your acceptance of this License to do so.
+
+   10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically receives
+a license from the original licensors, to run, modify and propagate that work,
+subject to this License. You are not responsible for enforcing compliance
+by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an organization,
+or substantially all assets of one, or subdividing an organization, or merging
+organizations. If propagation of a covered work results from an entity transaction,
+each party to that transaction who receives a copy of the work also receives
+whatever licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the Corresponding
+Source of the work from the predecessor in interest, if the predecessor has
+it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the rights
+granted or affirmed under this License. For example, you may not impose a
+license fee, royalty, or other charge for exercise of rights granted under
+this License, and you may not initiate litigation (including a cross-claim
+or counterclaim in a lawsuit) alleging that any patent claim is infringed
+by making, using, selling, offering for sale, or importing the Program or
+any portion of it.
+
+   11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this License
+of the Program or a work on which the Program is based. The work thus licensed
+is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims owned or controlled
+by the contributor, whether already acquired or hereafter acquired, that would
+be infringed by some manner, permitted by this License, of making, using,
+or selling its contributor version, but do not include claims that would be
+infringed only as a consequence of further modification of the contributor
+version. For purposes of this definition, "control" includes the right to
+grant patent sublicenses in a manner consistent with the requirements of this
+License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free patent
+license under the contributor's essential patent claims, to make, use, sell,
+offer for sale, import and otherwise run, modify and propagate the contents
+of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express agreement
+or commitment, however denominated, not to enforce a patent (such as an express
+permission to practice a patent or covenant not to sue for patent infringement).
+To "grant" such a patent license to a party means to make such an agreement
+or commitment not to enforce a patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license, and the
+Corresponding Source of the work is not available for anyone to copy, free
+of charge and under the terms of this License, through a publicly available
+network server or other readily accessible means, then you must either (1)
+cause the Corresponding Source to be so available, or (2) arrange to deprive
+yourself of the benefit of the patent license for this particular work, or
+(3) arrange, in a manner consistent with the requirements of this License,
+to extend the patent license to downstream recipients. "Knowingly relying"
+means you have actual knowledge that, but for the patent license, your conveying
+the covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that country
+that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or arrangement,
+you convey, or propagate by procuring conveyance of, a covered work, and grant
+a patent license to some of the parties receiving the covered work authorizing
+them to use, propagate, modify or convey a specific copy of the covered work,
+then the patent license you grant is automatically extended to all recipients
+of the covered work and works based on it.
+
+A patent license is "discriminatory" if it does not include within the scope
+of its coverage, prohibits the exercise of, or is conditioned on the non-exercise
+of one or more of the rights that are specifically granted under this License.
+You may not convey a covered work if you are a party to an arrangement with
+a third party that is in the business of distributing software, under which
+you make payment to the third party based on the extent of your activity of
+conveying the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by you
+(or copies made from those copies), or (b) primarily for and in connection
+with specific products or compilations that contain the covered work, unless
+you entered into that arrangement, or that patent license was granted, prior
+to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting any implied
+license or other defenses to infringement that may otherwise be available
+to you under applicable patent law.
+
+   12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or otherwise)
+that contradict the conditions of this License, they do not excuse you from
+the conditions of this License. If you cannot convey a covered work so as
+to satisfy simultaneously your obligations under this License and any other
+pertinent obligations, then as a consequence you may not convey it at all.
+For example, if you agree to terms that obligate you to collect a royalty
+for further conveying from those to whom you convey the Program, the only
+way you could satisfy both those terms and this License would be to refrain
+entirely from conveying the Program.
+
+   13. Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have permission to
+link or combine any covered work with a work licensed under version 3 of the
+GNU Affero General Public License into a single combined work, and to convey
+the resulting work. The terms of this License will continue to apply to the
+part which is the covered work, but the special requirements of the GNU Affero
+General Public License, section 13, concerning interaction through a network
+will apply to the combination as such.
+
+   14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions of the
+GNU General Public License from time to time. Such new versions will be similar
+in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies
+that a certain numbered version of the GNU General Public License "or any
+later version" applies to it, you have the option of following the terms and
+conditions either of that numbered version or of any later version published
+by the Free Software Foundation. If the Program does not specify a version
+number of the GNU General Public License, you may choose any version ever
+published by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions of
+the GNU General Public License can be used, that proxy's public statement
+of acceptance of a version permanently authorizes you to choose that version
+for the Program.
+
+Later license versions may give you additional or different permissions. However,
+no additional obligations are imposed on any author or copyright holder as
+a result of your choosing to follow a later version.
+
+   15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
+LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
+OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
+PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+   16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
+ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM
+AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
+USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
+PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+   17. Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided above cannot
+be given local legal effect according to their terms, reviewing courts shall
+apply local law that most closely approximates an absolute waiver of all civil
+liability in connection with the Program, unless a warranty or assumption
+of liability accompanies a copy of the Program in return for a fee. END OF
+TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible
+use to the public, the best way to achieve this is to make it free software
+which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach
+them to the start of each source file to most effectively state the exclusion
+of warranty; and each file should have at least the "copyright" line and a
+pointer to where the full notice is found.
+
+<one line to give the program's name and a brief idea of what it does.>
+
+Copyright (C) <year> <name of author>
+
+This program is free software: you can redistribute it and/or modify it under
+the terms of the GNU General Public License as published by the Free Software
+Foundation, either version 3 of the License, or (at your option) any later
+version.
+
+This program is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
+FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
+
+You should have received a copy of the GNU General Public License along with
+this program. If not, see <http s ://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program does terminal interaction, make it output a short notice like
+this when it starts in an interactive mode:
+
+<program> Copyright (C) <year> <name of author>
+
+This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+
+This is free software, and you are welcome to redistribute it under certain
+conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands might
+be different; for a GUI interface, you would use an "about box".
+
+You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary. For
+more information on this, and how to apply and follow the GNU GPL, see <http
+s ://www.gnu.org/licenses/>.
+
+The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General Public
+License instead of this License. But first, please read <http s ://www.gnu.org/
+licenses /why-not-lgpl.html>.

+GNU GENERAL PUBLIC LICENSE
+
+Version 3, 29 June 2007
+
+Copyright © 2007 Free Software Foundation, Inc. <http s ://fsf.org/>
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The GNU General Public License is a free, copyleft license for software and
+other kinds of works.
+
+The licenses for most software and other practical works are designed to take
+away your freedom to share and change the works. By contrast, the GNU General
+Public License is intended to guarantee your freedom to share and change all
+versions of a program--to make sure it remains free software for all its users.
+We, the Free Software Foundation, use the GNU General Public License for most
+of our software; it applies also to any other work released this way by its
+authors. You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for them if you wish), that
+you receive source code or can get it if you want it, that you can change
+the software or use pieces of it in new free programs, and that you know you
+can do these things.
+
+To protect your rights, we need to prevent others from denying you these rights
+or asking you to surrender the rights. Therefore, you have certain responsibilities
+if you distribute copies of the software, or if you modify it: responsibilities
+to respect the freedom of others.
+
+For example, if you distribute copies of such a program, whether gratis or
+for a fee, you must pass on to the recipients the same freedoms that you received.
+You must make sure that they, too, receive or can get the source code. And
+you must show them these terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps: (1) assert
+copyright on the software, and (2) offer you this License giving you legal
+permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains that
+there is no warranty for this free software. For both users' and authors'
+sake, the GPL requires that modified versions be marked as changed, so that
+their problems will not be attributed erroneously to authors of previous versions.
+
+Some devices are designed to deny users access to install or run modified
+versions of the software inside them, although the manufacturer can do so.
+This is fundamentally incompatible with the aim of protecting users' freedom
+to change the software. The systematic pattern of such abuse occurs in the
+area of products for individuals to use, which is precisely where it is most
+unacceptable. Therefore, we have designed this version of the GPL to prohibit
+the practice for those products. If such problems arise substantially in other
+domains, we stand ready to extend this provision to those domains in future
+versions of the GPL, as needed to protect the freedom of users.
+
+Finally, every program is threatened constantly by software patents. States
+should not allow patents to restrict development and use of software on general-purpose
+computers, but in those that do, we wish to avoid the special danger that
+patents applied to a free program could make it effectively proprietary. To
+prevent this, the GPL assures that patents cannot be used to render the program
+non-free.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+TERMS AND CONDITIONS
+
+   0. Definitions.
+
+   "This License" refers to version 3 of the GNU General Public License.
+
+"Copyright" also means copyright-like laws that apply to other kinds of works,
+such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this License.
+Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals
+or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work in
+a fashion requiring copyright permission, other than the making of an exact
+copy. The resulting work is called a "modified version" of the earlier work
+or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based on the
+Program.
+
+To "propagate" a work means to do anything with it that, without permission,
+would make you directly or secondarily liable for infringement under applicable
+copyright law, except executing it on a computer or modifying a private copy.
+Propagation includes copying, distribution (with or without modification),
+making available to the public, and in some countries other activities as
+well.
+
+To "convey" a work means any kind of propagation that enables other parties
+to make or receive copies. Mere interaction with a user through a computer
+network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays "Appropriate Legal Notices" to the
+extent that it includes a convenient and prominently visible feature that
+(1) displays an appropriate copyright notice, and (2) tells the user that
+there is no warranty for the work (except to the extent that warranties are
+provided), that licensees may convey the work under this License, and how
+to view a copy of this License. If the interface presents a list of user commands
+or options, such as a menu, a prominent item in the list meets this criterion.
+
+   1. Source Code.
+
+The "source code" for a work means the preferred form of the work for making
+modifications to it. "Object code" means any non-source form of a work.
+
+A "Standard Interface" means an interface that either is an official standard
+defined by a recognized standards body, or, in the case of interfaces specified
+for a particular programming language, one that is widely used among developers
+working in that language.
+
+The "System Libraries" of an executable work include anything, other than
+the work as a whole, that (a) is included in the normal form of packaging
+a Major Component, but which is not part of that Major Component, and (b)
+serves only to enable use of the work with that Major Component, or to implement
+a Standard Interface for which an implementation is available to the public
+in source code form. A "Major Component", in this context, means a major essential
+component (kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to produce
+the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all the source
+code needed to generate, install, and (for an executable work) run the object
+code and to modify the work, including scripts to control those activities.
+However, it does not include the work's System Libraries, or general-purpose
+tools or generally available free programs which are used unmodified in performing
+those activities but which are not part of the work. For example, Corresponding
+Source includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically linked
+subprograms that the work is specifically designed to require, such as by
+intimate data communication or control flow between those subprograms and
+other parts of the work.
+
+The Corresponding Source need not include anything that users can regenerate
+automatically from other parts of the Corresponding Source.
+
+   The Corresponding Source for a work in source code form is that same work.
+
+   2. Basic Permissions.
+
+All rights granted under this License are granted for the term of copyright
+on the Program, and are irrevocable provided the stated conditions are met.
+This License explicitly affirms your unlimited permission to run the unmodified
+Program. The output from running a covered work is covered by this License
+only if the output, given its content, constitutes a covered work. This License
+acknowledges your rights of fair use or other equivalent, as provided by copyright
+law.
+
+You may make, run and propagate covered works that you do not convey, without
+conditions so long as your license otherwise remains in force. You may convey
+covered works to others for the sole purpose of having them make modifications
+exclusively for you, or provide you with facilities for running those works,
+provided that you comply with the terms of this License in conveying all material
+for which you do not control copyright. Those thus making or running the covered
+works for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of your copyrighted
+material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the conditions
+stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
+
+   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological measure
+under any applicable law fulfilling obligations under article 11 of the WIPO
+copyright treaty adopted on 20 December 1996, or similar laws prohibiting
+or restricting circumvention of such measures.
+
+When you convey a covered work, you waive any legal power to forbid circumvention
+of technological measures to the extent such circumvention is effected by
+exercising rights under this License with respect to the covered work, and
+you disclaim any intention to limit operation or modification of the work
+as a means of enforcing, against the work's users, your or third parties'
+legal rights to forbid circumvention of technological measures.
+
+   4. Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you receive
+it, in any medium, provided that you conspicuously and appropriately publish
+on each copy an appropriate copyright notice; keep intact all notices stating
+that this License and any non-permissive terms added in accord with section
+7 apply to the code; keep intact all notices of the absence of any warranty;
+and give all recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey, and you
+may offer support or warranty protection for a fee.
+
+   5. Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to produce
+it from the Program, in the form of source code under the terms of section
+4, provided that you also meet all of these conditions:
+
+a) The work must carry prominent notices stating that you modified it, and
+giving a relevant date.
+
+b) The work must carry prominent notices stating that it is released under
+this License and any conditions added under section 7. This requirement modifies
+the requirement in section 4 to "keep intact all notices".
+
+c) You must license the entire work, as a whole, under this License to anyone
+who comes into possession of a copy. This License will therefore apply, along
+with any applicable section 7 additional terms, to the whole of the work,
+and all its parts, regardless of how they are packaged. This License gives
+no permission to license the work in any other way, but it does not invalidate
+such permission if you have separately received it.
+
+d) If the work has interactive user interfaces, each must display Appropriate
+Legal Notices; however, if the Program has interactive interfaces that do
+not display Appropriate Legal Notices, your work need not make them do so.
+
+A compilation of a covered work with other separate and independent works,
+which are not by their nature extensions of the covered work, and which are
+not combined with it such as to form a larger program, in or on a volume of
+a storage or distribution medium, is called an "aggregate" if the compilation
+and its resulting copyright are not used to limit the access or legal rights
+of the compilation's users beyond what the individual works permit. Inclusion
+of a covered work in an aggregate does not cause this License to apply to
+the other parts of the aggregate.
+
+   6. Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of sections
+4 and 5, provided that you also convey the machine-readable Corresponding
+Source under the terms of this License, in one of these ways:
+
+a) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by the Corresponding Source fixed
+on a durable physical medium customarily used for software interchange.
+
+b) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by a written offer, valid for
+at least three years and valid for as long as you offer spare parts or customer
+support for that product model, to give anyone who possesses the object code
+either (1) a copy of the Corresponding Source for all the software in the
+product that is covered by this License, on a durable physical medium customarily
+used for software interchange, for a price no more than your reasonable cost
+of physically performing this conveying of source, or (2) access to copy the
+Corresponding Source from a network server at no charge.
+
+c) Convey individual copies of the object code with a copy of the written
+offer to provide the Corresponding Source. This alternative is allowed only
+occasionally and noncommercially, and only if you received the object code
+with such an offer, in accord with subsection 6b.
+
+d) Convey the object code by offering access from a designated place (gratis
+or for a charge), and offer equivalent access to the Corresponding Source
+in the same way through the same place at no further charge. You need not
+require recipients to copy the Corresponding Source along with the object
+code. If the place to copy the object code is a network server, the Corresponding
+Source may be on a different server (operated by you or a third party) that
+supports equivalent copying facilities, provided you maintain clear directions
+next to the object code saying where to find the Corresponding Source. Regardless
+of what server hosts the Corresponding Source, you remain obligated to ensure
+that it is available for as long as needed to satisfy these requirements.
+
+e) Convey the object code using peer-to-peer transmission, provided you inform
+other peers where the object code and Corresponding Source of the work are
+being offered to the general public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded from
+the Corresponding Source as a System Library, need not be included in conveying
+the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any tangible
+personal property which is normally used for personal, family, or household
+purposes, or (2) anything designed or sold for incorporation into a dwelling.
+In determining whether a product is a consumer product, doubtful cases shall
+be resolved in favor of coverage. For a particular product received by a particular
+user, "normally used" refers to a typical or common use of that class of product,
+regardless of the status of the particular user or of the way in which the
+particular user actually uses, or expects or is expected to use, the product.
+A product is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent the
+only significant mode of use of the product.
+
+"Installation Information" for a User Product means any methods, procedures,
+authorization keys, or other information required to install and execute modified
+versions of a covered work in that User Product from a modified version of
+its Corresponding Source. The information must suffice to ensure that the
+continued functioning of the modified object code is in no case prevented
+or interfered with solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or specifically
+for use in, a User Product, and the conveying occurs as part of a transaction
+in which the right of possession and use of the User Product is transferred
+to the recipient in perpetuity or for a fixed term (regardless of how the
+transaction is characterized), the Corresponding Source conveyed under this
+section must be accompanied by the Installation Information. But this requirement
+does not apply if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has been installed
+in ROM).
+
+The requirement to provide Installation Information does not include a requirement
+to continue to provide support service, warranty, or updates for a work that
+has been modified or installed by the recipient, or for the User Product in
+which it has been modified or installed. Access to a network may be denied
+when the modification itself materially and adversely affects the operation
+of the network or violates the rules and protocols for communication across
+the network.
+
+Corresponding Source conveyed, and Installation Information provided, in accord
+with this section must be in a format that is publicly documented (and with
+an implementation available to the public in source code form), and must require
+no special password or key for unpacking, reading or copying.
+
+   7. Additional Terms.
+
+"Additional permissions" are terms that supplement the terms of this License
+by making exceptions from one or more of its conditions. Additional permissions
+that are applicable to the entire Program shall be treated as though they
+were included in this License, to the extent that they are valid under applicable
+law. If additional permissions apply only to part of the Program, that part
+may be used separately under those permissions, but the entire Program remains
+governed by this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option remove any
+additional permissions from that copy, or from any part of it. (Additional
+permissions may be written to require their own removal in certain cases when
+you modify the work.) You may place additional permissions on material, added
+by you to a covered work, for which you have or can give appropriate copyright
+permission.
+
+Notwithstanding any other provision of this License, for material you add
+to a covered work, you may (if authorized by the copyright holders of that
+material) supplement the terms of this License with terms:
+
+a) Disclaiming warranty or limiting liability differently from the terms of
+sections 15 and 16 of this License; or
+
+b) Requiring preservation of specified reasonable legal notices or author
+attributions in that material or in the Appropriate Legal Notices displayed
+by works containing it; or
+
+c) Prohibiting misrepresentation of the origin of that material, or requiring
+that modified versions of such material be marked in reasonable ways as different
+from the original version; or
+
+d) Limiting the use for publicity purposes of names of licensors or authors
+of the material; or
+
+e) Declining to grant rights under trademark law for use of some trade names,
+trademarks, or service marks; or
+
+f) Requiring indemnification of licensors and authors of that material by
+anyone who conveys the material (or modified versions of it) with contractual
+assumptions of liability to the recipient, for any liability that these contractual
+assumptions directly impose on those licensors and authors.
+
+All other non-permissive additional terms are considered "further restrictions"
+within the meaning of section 10. If the Program as you received it, or any
+part of it, contains a notice stating that it is governed by this License
+along with a term that is a further restriction, you may remove that term.
+If a license document contains a further restriction but permits relicensing
+or conveying under this License, you may add to a covered work material governed
+by the terms of that license document, provided that the further restriction
+does not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you must place,
+in the relevant source files, a statement of the additional terms that apply
+to those files, or a notice indicating where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the form
+of a separately written license, or stated as exceptions; the above requirements
+apply either way.
+
+   8. Termination.
+
+You may not propagate or modify a covered work except as expressly provided
+under this License. Any attempt otherwise to propagate or modify it is void,
+and will automatically terminate your rights under this License (including
+any patent licenses granted under the third paragraph of section 11).
+
+However, if you cease all violation of this License, then your license from
+a particular copyright holder is reinstated (a) provisionally, unless and
+until the copyright holder explicitly and finally terminates your license,
+and (b) permanently, if the copyright holder fails to notify you of the violation
+by some reasonable means prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is reinstated permanently
+if the copyright holder notifies you of the violation by some reasonable means,
+this is the first time you have received notice of violation of this License
+(for any work) from that copyright holder, and you cure the violation prior
+to 30 days after your receipt of the notice.
+
+Termination of your rights under this section does not terminate the licenses
+of parties who have received copies or rights from you under this License.
+If your rights have been terminated and not permanently reinstated, you do
+not qualify to receive new licenses for the same material under section 10.
+
+   9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run a copy
+of the Program. Ancillary propagation of a covered work occurring solely as
+a consequence of using peer-to-peer transmission to receive a copy likewise
+does not require acceptance. However, nothing other than this License grants
+you permission to propagate or modify any covered work. These actions infringe
+copyright if you do not accept this License. Therefore, by modifying or propagating
+a covered work, you indicate your acceptance of this License to do so.
+
+   10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically receives
+a license from the original licensors, to run, modify and propagate that work,
+subject to this License. You are not responsible for enforcing compliance
+by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an organization,
+or substantially all assets of one, or subdividing an organization, or merging
+organizations. If propagation of a covered work results from an entity transaction,
+each party to that transaction who receives a copy of the work also receives
+whatever licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the Corresponding
+Source of the work from the predecessor in interest, if the predecessor has
+it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the rights
+granted or affirmed under this License. For example, you may not impose a
+license fee, royalty, or other charge for exercise of rights granted under
+this License, and you may not initiate litigation (including a cross-claim
+or counterclaim in a lawsuit) alleging that any patent claim is infringed
+by making, using, selling, offering for sale, or importing the Program or
+any portion of it.
+
+   11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this License
+of the Program or a work on which the Program is based. The work thus licensed
+is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims owned or controlled
+by the contributor, whether already acquired or hereafter acquired, that would
+be infringed by some manner, permitted by this License, of making, using,
+or selling its contributor version, but do not include claims that would be
+infringed only as a consequence of further modification of the contributor
+version. For purposes of this definition, "control" includes the right to
+grant patent sublicenses in a manner consistent with the requirements of this
+License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free patent
+license under the contributor's essential patent claims, to make, use, sell,
+offer for sale, import and otherwise run, modify and propagate the contents
+of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express agreement
+or commitment, however denominated, not to enforce a patent (such as an express
+permission to practice a patent or covenant not to sue for patent infringement).
+To "grant" such a patent license to a party means to make such an agreement
+or commitment not to enforce a patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license, and the
+Corresponding Source of the work is not available for anyone to copy, free
+of charge and under the terms of this License, through a publicly available
+network server or other readily accessible means, then you must either (1)
+cause the Corresponding Source to be so available, or (2) arrange to deprive
+yourself of the benefit of the patent license for this particular work, or
+(3) arrange, in a manner consistent with the requirements of this License,
+to extend the patent license to downstream recipients. "Knowingly relying"
+means you have actual knowledge that, but for the patent license, your conveying
+the covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that country
+that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or arrangement,
+you convey, or propagate by procuring conveyance of, a covered work, and grant
+a patent license to some of the parties receiving the covered work authorizing
+them to use, propagate, modify or convey a specific copy of the covered work,
+then the patent license you grant is automatically extended to all recipients
+of the covered work and works based on it.
+
+A patent license is "discriminatory" if it does not include within the scope
+of its coverage, prohibits the exercise of, or is conditioned on the non-exercise
+of one or more of the rights that are specifically granted under this License.
+You may not convey a covered work if you are a party to an arrangement with
+a third party that is in the business of distributing software, under which
+you make payment to the third party based on the extent of your activity of
+conveying the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by you
+(or copies made from those copies), or (b) primarily for and in connection
+with specific products or compilations that contain the covered work, unless
+you entered into that arrangement, or that patent license was granted, prior
+to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting any implied
+license or other defenses to infringement that may otherwise be available
+to you under applicable patent law.
+
+   12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or otherwise)
+that contradict the conditions of this License, they do not excuse you from
+the conditions of this License. If you cannot convey a covered work so as
+to satisfy simultaneously your obligations under this License and any other
+pertinent obligations, then as a consequence you may not convey it at all.
+For example, if you agree to terms that obligate you to collect a royalty
+for further conveying from those to whom you convey the Program, the only
+way you could satisfy both those terms and this License would be to refrain
+entirely from conveying the Program.
+
+   13. Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have permission to
+link or combine any covered work with a work licensed under version 3 of the
+GNU Affero General Public License into a single combined work, and to convey
+the resulting work. The terms of this License will continue to apply to the
+part which is the covered work, but the special requirements of the GNU Affero
+General Public License, section 13, concerning interaction through a network
+will apply to the combination as such.
+
+   14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions of the
+GNU General Public License from time to time. Such new versions will be similar
+in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies
+that a certain numbered version of the GNU General Public License "or any
+later version" applies to it, you have the option of following the terms and
+conditions either of that numbered version or of any later version published
+by the Free Software Foundation. If the Program does not specify a version
+number of the GNU General Public License, you may choose any version ever
+published by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions of
+the GNU General Public License can be used, that proxy's public statement
+of acceptance of a version permanently authorizes you to choose that version
+for the Program.
+
+Later license versions may give you additional or different permissions. However,
+no additional obligations are imposed on any author or copyright holder as
+a result of your choosing to follow a later version.
+
+   15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
+LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
+OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
+PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+   16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
+ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM
+AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
+USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
+PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+   17. Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided above cannot
+be given local legal effect according to their terms, reviewing courts shall
+apply local law that most closely approximates an absolute waiver of all civil
+liability in connection with the Program, unless a warranty or assumption
+of liability accompanies a copy of the Program in return for a fee. END OF
+TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible
+use to the public, the best way to achieve this is to make it free software
+which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach
+them to the start of each source file to most effectively state the exclusion
+of warranty; and each file should have at least the "copyright" line and a
+pointer to where the full notice is found.
+
+<one line to give the program's name and a brief idea of what it does.>
+
+Copyright (C) <year> <name of author>
+
+This program is free software: you can redistribute it and/or modify it under
+the terms of the GNU General Public License as published by the Free Software
+Foundation, either version 3 of the License, or (at your option) any later
+version.
+
+This program is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
+FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
+
+You should have received a copy of the GNU General Public License along with
+this program. If not, see <http s ://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program does terminal interaction, make it output a short notice like
+this when it starts in an interactive mode:
+
+<program> Copyright (C) <year> <name of author>
+
+This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+
+This is free software, and you are welcome to redistribute it under certain
+conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands might
+be different; for a GUI interface, you would use an "about box".
+
+You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary. For
+more information on this, and how to apply and follow the GNU GPL, see <http
+s ://www.gnu.org/licenses/>.
+
+The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General Public
+License instead of this License. But first, please read <http s ://www.gnu.org/
+licenses /why-not-lgpl.html>.

+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for them if you wish), that
+you receive source code or can get it if you want it, that you can change
+the software or use pieces of it in new free programs, and that you know you
+can do these things.
+
+To protect your rights, we need to prevent others from denying you these rights
+or asking you to surrender the rights. Therefore, you have certain responsibilities
+if you distribute copies of the software, or if you modify it: responsibilities
+to respect the freedom of others.
+
+For example, if you distribute copies of such a program, whether gratis or
+for a fee, you must pass on to the recipients the same freedoms that you received.
+You must make sure that they, too, receive or can get the source code. And
+you must show them these terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps: (1) assert
+copyright on the software, and (2) offer you this License giving you legal
+permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains that
+there is no warranty for this free software. For both users' and authors'
+sake, the GPL requires that modified versions be marked as changed, so that
+their problems will not be attributed erroneously to authors of previous versions.
+
+Some devices are designed to deny users access to install or run modified
+versions of the software inside them, although the manufacturer can do so.
+This is fundamentally incompatible with the aim of protecting users' freedom
+to change the software. The systematic pattern of such abuse occurs in the
+area of products for individuals to use, which is precisely where it is most
+unacceptable. Therefore, we have designed this version of the GPL to prohibit
+the practice for those products. If such problems arise substantially in other
+domains, we stand ready to extend this provision to those domains in future
+versions of the GPL, as needed to protect the freedom of users.
+
+Finally, every program is threatened constantly by software patents. States
+should not allow patents to restrict development and use of software on general-purpose
+computers, but in those that do, we wish to avoid the special danger that
+patents applied to a free program could make it effectively proprietary. To
+prevent this, the GPL assures that patents cannot be used to render the program
+non-free.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+TERMS AND CONDITIONS
+
+   0. Definitions.
+
+   "This License" refers to version 3 of the GNU General Public License.
+
+"Copyright" also means copyright-like laws that apply to other kinds of works,
+such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this License.
+Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals
+or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work in
+a fashion requiring copyright permission, other than the making of an exact
+copy. The resulting work is called a "modified version" of the earlier work
+or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based on the
+Program.
+
+To "propagate" a work means to do anything with it that, without permission,
+would make you directly or secondarily liable for infringement under applicable
+copyright law, except executing it on a computer or modifying a private copy.
+Propagation includes copying, distribution (with or without modification),
+making available to the public, and in some countries other activities as
+well.
+
+To "convey" a work means any kind of propagation that enables other parties
+to make or receive copies. Mere interaction with a user through a computer
+network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays "Appropriate Legal Notices" to the
+extent that it includes a convenient and prominently visible feature that
+(1) displays an appropriate copyright notice, and (2) tells the user that
+there is no warranty for the work (except to the extent that warranties are
+provided), that licensees may convey the work under this License, and how
+to view a copy of this License. If the interface presents a list of user commands
+or options, such as a menu, a prominent item in the list meets this criterion.
+
+   1. Source Code.
+
+The "source code" for a work means the preferred form of the work for making
+modifications to it. "Object code" means any non-source form of a work.
+
+A "Standard Interface" means an interface that either is an official standard
+defined by a recognized standards body, or, in the case of interfaces specified
+for a particular programming language, one that is widely used among developers
+working in that language.
+
+The "System Libraries" of an executable work include anything, other than
+the work as a whole, that (a) is included in the normal form of packaging
+a Major Component, but which is not part of that Major Component, and (b)
+serves only to enable use of the work with that Major Component, or to implement
+a Standard Interface for which an implementation is available to the public
+in source code form. A "Major Component", in this context, means a major essential
+component (kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to produce
+the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all the source
+code needed to generate, install, and (for an executable work) run the object
+code and to modify the work, including scripts to control those activities.
+However, it does not include the work's System Libraries, or general-purpose
+tools or generally available free programs which are used unmodified in performing
+those activities but which are not part of the work. For example, Corresponding
+Source includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically linked
+subprograms that the work is specifically designed to require, such as by
+intimate data communication or control flow between those subprograms and
+other parts of the work.
+
+The Corresponding Source need not include anything that users can regenerate
+automatically from other parts of the Corresponding Source.
+
+   The Corresponding Source for a work in source code form is that same work.
+
+   2. Basic Permissions.
+
+All rights granted under this License are granted for the term of copyright
+on the Program, and are irrevocable provided the stated conditions are met.
+This License explicitly affirms your unlimited permission to run the unmodified
+Program. The output from running a covered work is covered by this License
+only if the output, given its content, constitutes a covered work. This License
+acknowledges your rights of fair use or other equivalent, as provided by copyright
+law.
+
+You may make, run and propagate covered works that you do not convey, without
+conditions so long as your license otherwise remains in force. You may convey
+covered works to others for the sole purpose of having them make modifications
+exclusively for you, or provide you with facilities for running those works,
+provided that you comply with the terms of this License in conveying all material
+for which you do not control copyright. Those thus making or running the covered
+works for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of your copyrighted
+material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the conditions
+stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
+
+   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological measure
+under any applicable law fulfilling obligations under article 11 of the WIPO
+copyright treaty adopted on 20 December 1996, or similar laws prohibiting
+or restricting circumvention of such measures.
+
+When you convey a covered work, you waive any legal power to forbid circumvention
+of technological measures to the extent such circumvention is effected by
+exercising rights under this License with respect to the covered work, and
+you disclaim any intention to limit operation or modification of the work
+as a means of enforcing, against the work's users, your or third parties'
+legal rights to forbid circumvention of technological measures.
+
+   4. Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you receive
+it, in any medium, provided that you conspicuously and appropriately publish
+on each copy an appropriate copyright notice; keep intact all notices stating
+that this License and any non-permissive terms added in accord with section
+7 apply to the code; keep intact all notices of the absence of any warranty;
+and give all recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey, and you
+may offer support or warranty protection for a fee.
+
+   5. Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to produce
+it from the Program, in the form of source code under the terms of section
+4, provided that you also meet all of these conditions:
+
+a) The work must carry prominent notices stating that you modified it, and
+giving a relevant date.
+
+b) The work must carry prominent notices stating that it is released under
+this License and any conditions added under section 7. This requirement modifies
+the requirement in section 4 to "keep intact all notices".
+
+c) You must license the entire work, as a whole, under this License to anyone
+who comes into possession of a copy. This License will therefore apply, along
+with any applicable section 7 additional terms, to the whole of the work,
+and all its parts, regardless of how they are packaged. This License gives
+no permission to license the work in any other way, but it does not invalidate
+such permission if you have separately received it.
+
+d) If the work has interactive user interfaces, each must display Appropriate
+Legal Notices; however, if the Program has interactive interfaces that do
+not display Appropriate Legal Notices, your work need not make them do so.
+
+A compilation of a covered work with other separate and independent works,
+which are not by their nature extensions of the covered work, and which are
+not combined with it such as to form a larger program, in or on a volume of
+a storage or distribution medium, is called an "aggregate" if the compilation
+and its resulting copyright are not used to limit the access or legal rights
+of the compilation's users beyond what the individual works permit. Inclusion
+of a covered work in an aggregate does not cause this License to apply to
+the other parts of the aggregate.
+
+   6. Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of sections
+4 and 5, provided that you also convey the machine-readable Corresponding
+Source under the terms of this License, in one of these ways:
+
+a) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by the Corresponding Source fixed
+on a durable physical medium customarily used for software interchange.
+
+b) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by a written offer, valid for
+at least three years and valid for as long as you offer spare parts or customer
+support for that product model, to give anyone who possesses the object code
+either (1) a copy of the Corresponding Source for all the software in the
+product that is covered by this License, on a durable physical medium customarily
+used for software interchange, for a price no more than your reasonable cost
+of physically performing this conveying of source, or (2) access to copy the
+Corresponding Source from a network server at no charge.
+
+c) Convey individual copies of the object code with a copy of the written
+offer to provide the Corresponding Source. This alternative is allowed only
+occasionally and noncommercially, and only if you received the object code
+with such an offer, in accord with subsection 6b.
+
+d) Convey the object code by offering access from a designated place (gratis
+or for a charge), and offer equivalent access to the Corresponding Source
+in the same way through the same place at no further charge. You need not
+require recipients to copy the Corresponding Source along with the object
+code. If the place to copy the object code is a network server, the Corresponding
+Source may be on a different server (operated by you or a third party) that
+supports equivalent copying facilities, provided you maintain clear directions
+next to the object code saying where to find the Corresponding Source. Regardless
+of what server hosts the Corresponding Source, you remain obligated to ensure
+that it is available for as long as needed to satisfy these requirements.
+
+e) Convey the object code using peer-to-peer transmission, provided you inform
+other peers where the object code and Corresponding Source of the work are
+being offered to the general public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded from
+the Corresponding Source as a System Library, need not be included in conveying
+the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any tangible
+personal property which is normally used for personal, family, or household
+purposes, or (2) anything designed or sold for incorporation into a dwelling.
+In determining whether a product is a consumer product, doubtful cases shall
+be resolved in favor of coverage. For a particular product received by a particular
+user, "normally used" refers to a typical or common use of that class of product,
+regardless of the status of the particular user or of the way in which the
+particular user actually uses, or expects or is expected to use, the product.
+A product is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent the
+only significant mode of use of the product.
+
+"Installation Information" for a User Product means any methods, procedures,
+authorization keys, or other information required to install and execute modified
+versions of a covered work in that User Product from a modified version of
+its Corresponding Source. The information must suffice to ensure that the
+continued functioning of the modified object code is in no case prevented
+or interfered with solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or specifically
+for use in, a User Product, and the conveying occurs as part of a transaction
+in which the right of possession and use of the User Product is transferred
+to the recipient in perpetuity or for a fixed term (regardless of how the
+transaction is characterized), the Corresponding Source conveyed under this
+section must be accompanied by the Installation Information. But this requirement
+does not apply if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has been installed
+in ROM).
+
+The requirement to provide Installation Information does not include a requirement
+to continue to provide support service, warranty, or updates for a work that
+has been modified or installed by the recipient, or for the User Product in
+which it has been modified or installed. Access to a network may be denied
+when the modification itself materially and adversely affects the operation
+of the network or violates the rules and protocols for communication across
+the network.
+
+Corresponding Source conveyed, and Installation Information provided, in accord
+with this section must be in a format that is publicly documented (and with
+an implementation available to the public in source code form), and must require
+no special password or key for unpacking, reading or copying.
+
+   7. Additional Terms.
+
+"Additional permissions" are terms that supplement the terms of this License
+by making exceptions from one or more of its conditions. Additional permissions
+that are applicable to the entire Program shall be treated as though they
+were included in this License, to the extent that they are valid under applicable
+law. If additional permissions apply only to part of the Program, that part
+may be used separately under those permissions, but the entire Program remains
+governed by this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option remove any
+additional permissions from that copy, or from any part of it. (Additional
+permissions may be written to require their own removal in certain cases when
+you modify the work.) You may place additional permissions on material, added
+by you to a covered work, for which you have or can give appropriate copyright
+permission.
+
+Notwithstanding any other provision of this License, for material you add
+to a covered work, you may (if authorized by the copyright holders of that
+material) supplement the terms of this License with terms:
+
+a) Disclaiming warranty or limiting liability differently from the terms of
+sections 15 and 16 of this License; or
+
+b) Requiring preservation of specified reasonable legal notices or author
+attributions in that material or in the Appropriate Legal Notices displayed
+by works containing it; or
+
+c) Prohibiting misrepresentation of the origin of that material, or requiring
+that modified versions of such material be marked in reasonable ways as different
+from the original version; or
+
+d) Limiting the use for publicity purposes of names of licensors or authors
+of the material; or
+
+e) Declining to grant rights under trademark law for use of some trade names,
+trademarks, or service marks; or
+
+f) Requiring indemnification of licensors and authors of that material by
+anyone who conveys the material (or modified versions of it) with contractual
+assumptions of liability to the recipient, for any liability that these contractual
+assumptions directly impose on those licensors and authors.
+
+All other non-permissive additional terms are considered "further restrictions"
+within the meaning of section 10. If the Program as you received it, or any
+part of it, contains a notice stating that it is governed by this License
+along with a term that is a further restriction, you may remove that term.
+If a license document contains a further restriction but permits relicensing
+or conveying under this License, you may add to a covered work material governed
+by the terms of that license document, provided that the further restriction
+does not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you must place,
+in the relevant source files, a statement of the additional terms that apply
+to those files, or a notice indicating where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the form
+of a separately written license, or stated as exceptions; the above requirements
+apply either way.
+
+   8. Termination.
+
+You may not propagate or modify a covered work except as expressly provided
+under this License. Any attempt otherwise to propagate or modify it is void,
+and will automatically terminate your rights under this License (including
+any patent licenses granted under the third paragraph of section 11).
+
+However, if you cease all violation of this License, then your license from
+a particular copyright holder is reinstated (a) provisionally, unless and
+until the copyright holder explicitly and finally terminates your license,
+and (b) permanently, if the copyright holder fails to notify you of the violation
+by some reasonable means prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is reinstated permanently
+if the copyright holder notifies you of the violation by some reasonable means,
+this is the first time you have received notice of violation of this License
+(for any work) from that copyright holder, and you cure the violation prior
+to 30 days after your receipt of the notice.
+
+Termination of your rights under this section does not terminate the licenses
+of parties who have received copies or rights from you under this License.
+If your rights have been terminated and not permanently reinstated, you do
+not qualify to receive new licenses for the same material under section 10.
+
+   9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run a copy
+of the Program. Ancillary propagation of a covered work occurring solely as
+a consequence of using peer-to-peer transmission to receive a copy likewise
+does not require acceptance. However, nothing other than this License grants
+you permission to propagate or modify any covered work. These actions infringe
+copyright if you do not accept this License. Therefore, by modifying or propagating
+a covered work, you indicate your acceptance of this License to do so.
+
+   10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically receives
+a license from the original licensors, to run, modify and propagate that work,
+subject to this License. You are not responsible for enforcing compliance
+by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an organization,
+or substantially all assets of one, or subdividing an organization, or merging
+organizations. If propagation of a covered work results from an entity transaction,
+each party to that transaction who receives a copy of the work also receives
+whatever licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the Corresponding
+Source of the work from the predecessor in interest, if the predecessor has
+it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the rights
+granted or affirmed under this License. For example, you may not impose a
+license fee, royalty, or other charge for exercise of rights granted under
+this License, and you may not initiate litigation (including a cross-claim
+or counterclaim in a lawsuit) alleging that any patent claim is infringed
+by making, using, selling, offering for sale, or importing the Program or
+any portion of it.
+
+   11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this License
+of the Program or a work on which the Program is based. The work thus licensed
+is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims owned or controlled
+by the contributor, whether already acquired or hereafter acquired, that would
+be infringed by some manner, permitted by this License, of making, using,
+or selling its contributor version, but do not include claims that would be
+infringed only as a consequence of further modification of the contributor
+version. For purposes of this definition, "control" includes the right to
+grant patent sublicenses in a manner consistent with the requirements of this
+License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free patent
+license under the contributor's essential patent claims, to make, use, sell,
+offer for sale, import and otherwise run, modify and propagate the contents
+of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express agreement
+or commitment, however denominated, not to enforce a patent (such as an express
+permission to practice a patent or covenant not to sue for patent infringement).
+To "grant" such a patent license to a party means to make such an agreement
+or commitment not to enforce a patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license, and the
+Corresponding Source of the work is not available for anyone to copy, free
+of charge and under the terms of this License, through a publicly available
+network server or other readily accessible means, then you must either (1)
+cause the Corresponding Source to be so available, or (2) arrange to deprive
+yourself of the benefit of the patent license for this particular work, or
+(3) arrange, in a manner consistent with the requirements of this License,
+to extend the patent license to downstream recipients. "Knowingly relying"
+means you have actual knowledge that, but for the patent license, your conveying
+the covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that country
+that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or arrangement,
+you convey, or propagate by procuring conveyance of, a covered work, and grant
+a patent license to some of the parties receiving the covered work authorizing
+them to use, propagate, modify or convey a specific copy of the covered work,
+then the patent license you grant is automatically extended to all recipients
+of the covered work and works based on it.
+
+A patent license is "discriminatory" if it does not include within the scope
+of its coverage, prohibits the exercise of, or is conditioned on the non-exercise
+of one or more of the rights that are specifically granted under this License.
+You may not convey a covered work if you are a party to an arrangement with
+a third party that is in the business of distributing software, under which
+you make payment to the third party based on the extent of your activity of
+conveying the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by you
+(or copies made from those copies), or (b) primarily for and in connection
+with specific products or compilations that contain the covered work, unless
+you entered into that arrangement, or that patent license was granted, prior
+to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting any implied
+license or other defenses to infringement that may otherwise be available
+to you under applicable patent law.
+
+   12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or otherwise)
+that contradict the conditions of this License, they do not excuse you from
+the conditions of this License. If you cannot convey a covered work so as
+to satisfy simultaneously your obligations under this License and any other
+pertinent obligations, then as a consequence you may not convey it at all.
+For example, if you agree to terms that obligate you to collect a royalty
+for further conveying from those to whom you convey the Program, the only
+way you could satisfy both those terms and this License would be to refrain
+entirely from conveying the Program.
+
+   13. Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have permission to
+link or combine any covered work with a work licensed under version 3 of the
+GNU Affero General Public License into a single combined work, and to convey
+the resulting work. The terms of this License will continue to apply to the
+part which is the covered work, but the special requirements of the GNU Affero
+General Public License, section 13, concerning interaction through a network
+will apply to the combination as such.
+
+   14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions of the
+GNU General Public License from time to time. Such new versions will be similar
+in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies
+that a certain numbered version of the GNU General Public License "or any
+later version" applies to it, you have the option of following the terms and
+conditions either of that numbered version or of any later version published
+by the Free Software Foundation. If the Program does not specify a version
+number of the GNU General Public License, you may choose any version ever
+published by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions of
+the GNU General Public License can be used, that proxy's public statement
+of acceptance of a version permanently authorizes you to choose that version
+for the Program.
+
+Later license versions may give you additional or different permissions. However,
+no additional obligations are imposed on any author or copyright holder as
+a result of your choosing to follow a later version.
+
+   15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
+LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
+OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
+PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+   16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
+ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM
+AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
+USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
+PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+   17. Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided above cannot
+be given local legal effect according to their terms, reviewing courts shall
+apply local law that most closely approximates an absolute waiver of all civil
+liability in connection with the Program, unless a warranty or assumption
+of liability accompanies a copy of the Program in return for a fee. END OF
+TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible
+use to the public, the best way to achieve this is to make it free software
+which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach
+them to the start of each source file to most effectively state the exclusion
+of warranty; and each file should have at least the "copyright" line and a
+pointer to where the full notice is found.
+
+<one line to give the program's name and a brief idea of what it does.>
+
+Copyright (C) <year> <name of author>
+
+This program is free software: you can redistribute it and/or modify it under
+the terms of the GNU General Public License as published by the Free Software
+Foundation, either version 3 of the License, or (at your option) any later
+version.

+This program is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS

+this program. If not, see <http s ://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program does terminal interaction, make it output a short notice like
+this when it starts in an interactive mode:
+
+<program> Copyright (C) <year> <name of author>
+
+This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+
+This is free software, and you are welcome to redistribute it under certain

+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands might
+be different; for a GUI interface, you would use an "about box".
+
+You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary. For
+more information on this, and how to apply and follow the GNU GPL, see <http
+s ://www.gnu.org/licenses/>.
+
+The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General Public
+License instead of this License. But first, please read <http s ://www.gnu.org/
+licenses /why-not-lgpl.html>.

+GNU GENERAL PUBLIC LICENSE
+
+Version 3, 29 June 2007
+
+Copyright © 2007 Free Software Foundation, Inc. <http s ://fsf.org/>
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The GNU General Public License is a free, copyleft license for software and
+other kinds of works.
+
+The licenses for most software and other practical works are designed to take
+away your freedom to share and change the works. By contrast, the GNU General
+Public License is intended to guarantee your freedom to share and change all
+versions of a program--to make sure it remains free software for all its users.
+We, the Free Software Foundation, use the GNU General Public License for most
+of our software; it applies also to any other work released this way by its
+authors. You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for them if you wish), that
+you receive source code or can get it if you want it, that you can change
+the software or use pieces of it in new free programs, and that you know you
+can do these things.
+
+To protect your rights, we need to prevent others from denying you these rights
+or asking you to surrender the rights. Therefore, you have certain responsibilities
+if you distribute copies of the software, or if you modify it: responsibilities
+to respect the freedom of others.
+
+For example, if you distribute copies of such a program, whether gratis or
+for a fee, you must pass on to the recipients the same freedoms that you received.
+You must make sure that they, too, receive or can get the source code. And
+you must show them these terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps: (1) assert
+copyright on the software, and (2) offer you this License giving you legal
+permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains that
+there is no warranty for this free software. For both users' and authors'
+sake, the GPL requires that modified versions be marked as changed, so that
+their problems will not be attributed erroneously to authors of previous versions.
+
+Some devices are designed to deny users access to install or run modified
+versions of the software inside them, although the manufacturer can do so.
+This is fundamentally incompatible with the aim of protecting users' freedom
+to change the software. The systematic pattern of such abuse occurs in the
+area of products for individuals to use, which is precisely where it is most
+unacceptable. Therefore, we have designed this version of the GPL to prohibit
+the practice for those products. If such problems arise substantially in other
+domains, we stand ready to extend this provision to those domains in future
+versions of the GPL, as needed to protect the freedom of users.
+
+Finally, every program is threatened constantly by software patents. States
+should not allow patents to restrict development and use of software on general-purpose
+computers, but in those that do, we wish to avoid the special danger that
+patents applied to a free program could make it effectively proprietary. To
+prevent this, the GPL assures that patents cannot be used to render the program
+non-free.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+TERMS AND CONDITIONS
+
+   0. Definitions.
+
+   "This License" refers to version 3 of the GNU General Public License.
+
+"Copyright" also means copyright-like laws that apply to other kinds of works,
+such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this License.
+Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals
+or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work in
+a fashion requiring copyright permission, other than the making of an exact
+copy. The resulting work is called a "modified version" of the earlier work
+or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based on the
+Program.
+
+To "propagate" a work means to do anything with it that, without permission,
+would make you directly or secondarily liable for infringement under applicable
+copyright law, except executing it on a computer or modifying a private copy.
+Propagation includes copying, distribution (with or without modification),
+making available to the public, and in some countries other activities as
+well.
+
+To "convey" a work means any kind of propagation that enables other parties
+to make or receive copies. Mere interaction with a user through a computer
+network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays "Appropriate Legal Notices" to the
+extent that it includes a convenient and prominently visible feature that
+(1) displays an appropriate copyright notice, and (2) tells the user that
+there is no warranty for the work (except to the extent that warranties are
+provided), that licensees may convey the work under this License, and how
+to view a copy of this License. If the interface presents a list of user commands
+or options, such as a menu, a prominent item in the list meets this criterion.
+
+   1. Source Code.
+
+The "source code" for a work means the preferred form of the work for making
+modifications to it. "Object code" means any non-source form of a work.
+
+A "Standard Interface" means an interface that either is an official standard
+defined by a recognized standards body, or, in the case of interfaces specified
+for a particular programming language, one that is widely used among developers
+working in that language.
+
+The "System Libraries" of an executable work include anything, other than
+the work as a whole, that (a) is included in the normal form of packaging
+a Major Component, but which is not part of that Major Component, and (b)
+serves only to enable use of the work with that Major Component, or to implement
+a Standard Interface for which an implementation is available to the public
+in source code form. A "Major Component", in this context, means a major essential
+component (kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to produce
+the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all the source
+code needed to generate, install, and (for an executable work) run the object
+code and to modify the work, including scripts to control those activities.
+However, it does not include the work's System Libraries, or general-purpose
+tools or generally available free programs which are used unmodified in performing
+those activities but which are not part of the work. For example, Corresponding
+Source includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically linked
+subprograms that the work is specifically designed to require, such as by
+intimate data communication or control flow between those subprograms and
+other parts of the work.
+
+The Corresponding Source need not include anything that users can regenerate
+automatically from other parts of the Corresponding Source.
+
+   The Corresponding Source for a work in source code form is that same work.
+
+   2. Basic Permissions.
+
+All rights granted under this License are granted for the term of copyright
+on the Program, and are irrevocable provided the stated conditions are met.
+This License explicitly affirms your unlimited permission to run the unmodified
+Program. The output from running a covered work is covered by this License
+only if the output, given its content, constitutes a covered work. This License
+acknowledges your rights of fair use or other equivalent, as provided by copyright
+law.
+
+You may make, run and propagate covered works that you do not convey, without
+conditions so long as your license otherwise remains in force. You may convey
+covered works to others for the sole purpose of having them make modifications
+exclusively for you, or provide you with facilities for running those works,
+provided that you comply with the terms of this License in conveying all material
+for which you do not control copyright. Those thus making or running the covered
+works for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of your copyrighted
+material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the conditions
+stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
+
+   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological measure
+under any applicable law fulfilling obligations under article 11 of the WIPO
+copyright treaty adopted on 20 December 1996, or similar laws prohibiting
+or restricting circumvention of such measures.
+
+When you convey a covered work, you waive any legal power to forbid circumvention
+of technological measures to the extent such circumvention is effected by
+exercising rights under this License with respect to the covered work, and
+you disclaim any intention to limit operation or modification of the work
+as a means of enforcing, against the work's users, your or third parties'
+legal rights to forbid circumvention of technological measures.
+
+   4. Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you receive
+it, in any medium, provided that you conspicuously and appropriately publish
+on each copy an appropriate copyright notice; keep intact all notices stating
+that this License and any non-permissive terms added in accord with section
+7 apply to the code; keep intact all notices of the absence of any warranty;
+and give all recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey, and you
+may offer support or warranty protection for a fee.
+
+   5. Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to produce
+it from the Program, in the form of source code under the terms of section
+4, provided that you also meet all of these conditions:
+
+a) The work must carry prominent notices stating that you modified it, and
+giving a relevant date.
+
+b) The work must carry prominent notices stating that it is released under
+this License and any conditions added under section 7. This requirement modifies
+the requirement in section 4 to "keep intact all notices".
+
+c) You must license the entire work, as a whole, under this License to anyone
+who comes into possession of a copy. This License will therefore apply, along
+with any applicable section 7 additional terms, to the whole of the work,
+and all its parts, regardless of how they are packaged. This License gives
+no permission to license the work in any other way, but it does not invalidate
+such permission if you have separately received it.
+
+d) If the work has interactive user interfaces, each must display Appropriate
+Legal Notices; however, if the Program has interactive interfaces that do
+not display Appropriate Legal Notices, your work need not make them do so.
+
+A compilation of a covered work with other separate and independent works,
+which are not by their nature extensions of the covered work, and which are
+not combined with it such as to form a larger program, in or on a volume of
+a storage or distribution medium, is called an "aggregate" if the compilation
+and its resulting copyright are not used to limit the access or legal rights
+of the compilation's users beyond what the individual works permit. Inclusion
+of a covered work in an aggregate does not cause this License to apply to
+the other parts of the aggregate.
+
+   6. Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of sections
+4 and 5, provided that you also convey the machine-readable Corresponding
+Source under the terms of this License, in one of these ways:
+
+a) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by the Corresponding Source fixed
+on a durable physical medium customarily used for software interchange.
+
+b) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by a written offer, valid for
+at least three years and valid for as long as you offer spare parts or customer
+support for that product model, to give anyone who possesses the object code
+either (1) a copy of the Corresponding Source for all the software in the
+product that is covered by this License, on a durable physical medium customarily
+used for software interchange, for a price no more than your reasonable cost
+of physically performing this conveying of source, or (2) access to copy the
+Corresponding Source from a network server at no charge.
+
+c) Convey individual copies of the object code with a copy of the written
+offer to provide the Corresponding Source. This alternative is allowed only
+occasionally and noncommercially, and only if you received the object code
+with such an offer, in accord with subsection 6b.
+
+d) Convey the object code by offering access from a designated place (gratis
+or for a charge), and offer equivalent access to the Corresponding Source
+in the same way through the same place at no further charge. You need not
+require recipients to copy the Corresponding Source along with the object
+code. If the place to copy the object code is a network server, the Corresponding
+Source may be on a different server (operated by you or a third party) that
+supports equivalent copying facilities, provided you maintain clear directions
+next to the object code saying where to find the Corresponding Source. Regardless
+of what server hosts the Corresponding Source, you remain obligated to ensure
+that it is available for as long as needed to satisfy these requirements.
+
+e) Convey the object code using peer-to-peer transmission, provided you inform
+other peers where the object code and Corresponding Source of the work are
+being offered to the general public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded from
+the Corresponding Source as a System Library, need not be included in conveying
+the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any tangible
+personal property which is normally used for personal, family, or household
+purposes, or (2) anything designed or sold for incorporation into a dwelling.
+In determining whether a product is a consumer product, doubtful cases shall
+be resolved in favor of coverage. For a particular product received by a particular
+user, "normally used" refers to a typical or common use of that class of product,
+regardless of the status of the particular user or of the way in which the
+particular user actually uses, or expects or is expected to use, the product.
+A product is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent the
+only significant mode of use of the product.
+
+"Installation Information" for a User Product means any methods, procedures,
+authorization keys, or other information required to install and execute modified
+versions of a covered work in that User Product from a modified version of
+its Corresponding Source. The information must suffice to ensure that the
+continued functioning of the modified object code is in no case prevented
+or interfered with solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or specifically
+for use in, a User Product, and the conveying occurs as part of a transaction
+in which the right of possession and use of the User Product is transferred
+to the recipient in perpetuity or for a fixed term (regardless of how the
+transaction is characterized), the Corresponding Source conveyed under this
+section must be accompanied by the Installation Information. But this requirement
+does not apply if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has been installed
+in ROM).
+
+The requirement to provide Installation Information does not include a requirement
+to continue to provide support service, warranty, or updates for a work that
+has been modified or installed by the recipient, or for the User Product in
+which it has been modified or installed. Access to a network may be denied
+when the modification itself materially and adversely affects the operation
+of the network or violates the rules and protocols for communication across
+the network.
+
+Corresponding Source conveyed, and Installation Information provided, in accord
+with this section must be in a format that is publicly documented (and with
+an implementation available to the public in source code form), and must require
+no special password or key for unpacking, reading or copying.
+
+   7. Additional Terms.
+
+"Additional permissions" are terms that supplement the terms of this License
+by making exceptions from one or more of its conditions. Additional permissions
+that are applicable to the entire Program shall be treated as though they
+were included in this License, to the extent that they are valid under applicable
+law. If additional permissions apply only to part of the Program, that part
+may be used separately under those permissions, but the entire Program remains
+governed by this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option remove any
+additional permissions from that copy, or from any part of it. (Additional
+permissions may be written to require their own removal in certain cases when
+you modify the work.) You may place additional permissions on material, added
+by you to a covered work, for which you have or can give appropriate copyright
+permission.
+
+Notwithstanding any other provision of this License, for material you add
+to a covered work, you may (if authorized by the copyright holders of that
+material) supplement the terms of this License with terms:
+
+a) Disclaiming warranty or limiting liability differently from the terms of
+sections 15 and 16 of this License; or
+
+b) Requiring preservation of specified reasonable legal notices or author
+attributions in that material or in the Appropriate Legal Notices displayed
+by works containing it; or
+
+c) Prohibiting misrepresentation of the origin of that material, or requiring
+that modified versions of such material be marked in reasonable ways as different
+from the original version; or
+
+d) Limiting the use for publicity purposes of names of licensors or authors
+of the material; or
+
+e) Declining to grant rights under trademark law for use of some trade names,
+trademarks, or service marks; or
+
+f) Requiring indemnification of licensors and authors of that material by
+anyone who conveys the material (or modified versions of it) with contractual
+assumptions of liability to the recipient, for any liability that these contractual
+assumptions directly impose on those licensors and authors.
+
+All other non-permissive additional terms are considered "further restrictions"
+within the meaning of section 10. If the Program as you received it, or any
+part of it, contains a notice stating that it is governed by this License
+along with a term that is a further restriction, you may remove that term.
+If a license document contains a further restriction but permits relicensing
+or conveying under this License, you may add to a covered work material governed
+by the terms of that license document, provided that the further restriction
+does not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you must place,
+in the relevant source files, a statement of the additional terms that apply
+to those files, or a notice indicating where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the form
+of a separately written license, or stated as exceptions; the above requirements
+apply either way.
+
+   8. Termination.
+
+You may not propagate or modify a covered work except as expressly provided
+under this License. Any attempt otherwise to propagate or modify it is void,
+and will automatically terminate your rights under this License (including
+any patent licenses granted under the third paragraph of section 11).
+
+However, if you cease all violation of this License, then your license from
+a particular copyright holder is reinstated (a) provisionally, unless and
+until the copyright holder explicitly and finally terminates your license,
+and (b) permanently, if the copyright holder fails to notify you of the violation
+by some reasonable means prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is reinstated permanently
+if the copyright holder notifies you of the violation by some reasonable means,
+this is the first time you have received notice of violation of this License
+(for any work) from that copyright holder, and you cure the violation prior
+to 30 days after your receipt of the notice.
+
+Termination of your rights under this section does not terminate the licenses
+of parties who have received copies or rights from you under this License.
+If your rights have been terminated and not permanently reinstated, you do
+not qualify to receive new licenses for the same material under section 10.
+
+   9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run a copy
+of the Program. Ancillary propagation of a covered work occurring solely as
+a consequence of using peer-to-peer transmission to receive a copy likewise
+does not require acceptance. However, nothing other than this License grants
+you permission to propagate or modify any covered work. These actions infringe
+copyright if you do not accept this License. Therefore, by modifying or propagating
+a covered work, you indicate your acceptance of this License to do so.
+
+   10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically receives
+a license from the original licensors, to run, modify and propagate that work,
+subject to this License. You are not responsible for enforcing compliance
+by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an organization,
+or substantially all assets of one, or subdividing an organization, or merging
+organizations. If propagation of a covered work results from an entity transaction,
+each party to that transaction who receives a copy of the work also receives
+whatever licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the Corresponding
+Source of the work from the predecessor in interest, if the predecessor has
+it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the rights
+granted or affirmed under this License. For example, you may not impose a
+license fee, royalty, or other charge for exercise of rights granted under
+this License, and you may not initiate litigation (including a cross-claim
+or counterclaim in a lawsuit) alleging that any patent claim is infringed
+by making, using, selling, offering for sale, or importing the Program or
+any portion of it.
+
+   11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this License
+of the Program or a work on which the Program is based. The work thus licensed
+is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims owned or controlled
+by the contributor, whether already acquired or hereafter acquired, that would
+be infringed by some manner, permitted by this License, of making, using,
+or selling its contributor version, but do not include claims that would be
+infringed only as a consequence of further modification of the contributor
+version. For purposes of this definition, "control" includes the right to
+grant patent sublicenses in a manner consistent with the requirements of this
+License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free patent
+license under the contributor's essential patent claims, to make, use, sell,
+offer for sale, import and otherwise run, modify and propagate the contents
+of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express agreement
+or commitment, however denominated, not to enforce a patent (such as an express
+permission to practice a patent or covenant not to sue for patent infringement).
+To "grant" such a patent license to a party means to make such an agreement
+or commitment not to enforce a patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license, and the
+Corresponding Source of the work is not available for anyone to copy, free
+of charge and under the terms of this License, through a publicly available
+network server or other readily accessible means, then you must either (1)
+cause the Corresponding Source to be so available, or (2) arrange to deprive
+yourself of the benefit of the patent license for this particular work, or
+(3) arrange, in a manner consistent with the requirements of this License,
+to extend the patent license to downstream recipients. "Knowingly relying"
+means you have actual knowledge that, but for the patent license, your conveying
+the covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that country
+that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or arrangement,
+you convey, or propagate by procuring conveyance of, a covered work, and grant
+a patent license to some of the parties receiving the covered work authorizing
+them to use, propagate, modify or convey a specific copy of the covered work,
+then the patent license you grant is automatically extended to all recipients
+of the covered work and works based on it.
+
+A patent license is "discriminatory" if it does not include within the scope
+of its coverage, prohibits the exercise of, or is conditioned on the non-exercise
+of one or more of the rights that are specifically granted under this License.
+You may not convey a covered work if you are a party to an arrangement with
+a third party that is in the business of distributing software, under which
+you make payment to the third party based on the extent of your activity of
+conveying the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by you
+(or copies made from those copies), or (b) primarily for and in connection
+with specific products or compilations that contain the covered work, unless
+you entered into that arrangement, or that patent license was granted, prior
+to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting any implied
+license or other defenses to infringement that may otherwise be available
+to you under applicable patent law.
+
+   12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or otherwise)
+that contradict the conditions of this License, they do not excuse you from
+the conditions of this License. If you cannot convey a covered work so as
+to satisfy simultaneously your obligations under this License and any other
+pertinent obligations, then as a consequence you may not convey it at all.
+For example, if you agree to terms that obligate you to collect a royalty
+for further conveying from those to whom you convey the Program, the only
+way you could satisfy both those terms and this License would be to refrain
+entirely from conveying the Program.
+
+   13. Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have permission to
+link or combine any covered work with a work licensed under version 3 of the
+GNU Affero General Public License into a single combined work, and to convey
+the resulting work. The terms of this License will continue to apply to the
+part which is the covered work, but the special requirements of the GNU Affero
+General Public License, section 13, concerning interaction through a network
+will apply to the combination as such.
+
+   14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions of the
+GNU General Public License from time to time. Such new versions will be similar
+in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies
+that a certain numbered version of the GNU General Public License "or any
+later version" applies to it, you have the option of following the terms and
+conditions either of that numbered version or of any later version published
+by the Free Software Foundation. If the Program does not specify a version
+number of the GNU General Public License, you may choose any version ever
+published by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions of
+the GNU General Public License can be used, that proxy's public statement
+of acceptance of a version permanently authorizes you to choose that version
+for the Program.
+
+Later license versions may give you additional or different permissions. However,
+no additional obligations are imposed on any author or copyright holder as
+a result of your choosing to follow a later version.
+
+   15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
+LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
+OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
+PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+   16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
+ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM
+AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
+USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
+PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+   17. Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided above cannot
+be given local legal effect according to their terms, reviewing courts shall
+apply local law that most closely approximates an absolute waiver of all civil
+liability in connection with the Program, unless a warranty or assumption
+of liability accompanies a copy of the Program in return for a fee. END OF
+TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible
+use to the public, the best way to achieve this is to make it free software
+which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach
+them to the start of each source file to most effectively state the exclusion
+of warranty; and each file should have at least the "copyright" line and a
+pointer to where the full notice is found.
+
+<one line to give the program's name and a brief idea of what it does.>
+
+Copyright (C) <year> <name of author>
+
+This program is free software: you can redistribute it and/or modify it under
+the terms of the GNU General Public License as published by the Free Software
+Foundation, either version 3 of the License, or (at your option) any later
+version.
+
+This program is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
+FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
+
+You should have received a copy of the GNU General Public License along with
+this program. If not, see <http s ://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program does terminal interaction, make it output a short notice like
+this when it starts in an interactive mode:
+
+<program> Copyright (C) <year> <name of author>
+
+This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+
+This is free software, and you are welcome to redistribute it under certain
+conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands might
+be different; for a GUI interface, you would use an "about box".
+
+You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary. For
+more information on this, and how to apply and follow the GNU GPL, see <http
+s ://www.gnu.org/licenses/>.
+
+The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General Public
+License instead of this License. But first, please read <http s ://www.gnu.org/
+licenses /why-not-lgpl.html>.

+GNU GENERAL PUBLIC LICENSE
+
+Version 3, 29 June 2007
+
+Copyright © 2007 Free Software Foundation, Inc. <http s ://fsf.org/>
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The GNU General Public License is a free, copyleft license for software and
+other kinds of works.
+
+The licenses for most software and other practical works are designed to take
+away your freedom to share and change the works. By contrast, the GNU General
+Public License is intended to guarantee your freedom to share and change all
+versions of a program--to make sure it remains free software for all its users.
+We, the Free Software Foundation, use the GNU General Public License for most
+of our software; it applies also to any other work released this way by its
+authors. You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for them if you wish), that
+you receive source code or can get it if you want it, that you can change
+the software or use pieces of it in new free programs, and that you know you
+can do these things.
+
+To protect your rights, we need to prevent others from denying you these rights
+or asking you to surrender the rights. Therefore, you have certain responsibilities
+if you distribute copies of the software, or if you modify it: responsibilities
+to respect the freedom of others.
+
+For example, if you distribute copies of such a program, whether gratis or
+for a fee, you must pass on to the recipients the same freedoms that you received.
+You must make sure that they, too, receive or can get the source code. And
+you must show them these terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps: (1) assert
+copyright on the software, and (2) offer you this License giving you legal
+permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains that
+there is no warranty for this free software. For both users' and authors'
+sake, the GPL requires that modified versions be marked as changed, so that
+their problems will not be attributed erroneously to authors of previous versions.
+
+Some devices are designed to deny users access to install or run modified
+versions of the software inside them, although the manufacturer can do so.
+This is fundamentally incompatible with the aim of protecting users' freedom
+to change the software. The systematic pattern of such abuse occurs in the
+area of products for individuals to use, which is precisely where it is most
+unacceptable. Therefore, we have designed this version of the GPL to prohibit
+the practice for those products. If such problems arise substantially in other
+domains, we stand ready to extend this provision to those domains in future
+versions of the GPL, as needed to protect the freedom of users.
+
+Finally, every program is threatened constantly by software patents. States
+should not allow patents to restrict development and use of software on general-purpose
+computers, but in those that do, we wish to avoid the special danger that
+patents applied to a free program could make it effectively proprietary. To
+prevent this, the GPL assures that patents cannot be used to render the program
+non-free.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+TERMS AND CONDITIONS
+
+   0. Definitions.
+
+   "This License" refers to version 3 of the GNU General Public License.
+
+"Copyright" also means copyright-like laws that apply to other kinds of works,
+such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this License.
+Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals
+or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work in
+a fashion requiring copyright permission, other than the making of an exact
+copy. The resulting work is called a "modified version" of the earlier work
+or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based on the
+Program.
+
+To "propagate" a work means to do anything with it that, without permission,
+would make you directly or secondarily liable for infringement under applicable
+copyright law, except executing it on a computer or modifying a private copy.
+Propagation includes copying, distribution (with or without modification),
+making available to the public, and in some countries other activities as
+well.
+
+To "convey" a work means any kind of propagation that enables other parties
+to make or receive copies. Mere interaction with a user through a computer
+network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays "Appropriate Legal Notices" to the
+extent that it includes a convenient and prominently visible feature that
+(1) displays an appropriate copyright notice, and (2) tells the user that
+there is no warranty for the work (except to the extent that warranties are
+provided), that licensees may convey the work under this License, and how
+to view a copy of this License. If the interface presents a list of user commands
+or options, such as a menu, a prominent item in the list meets this criterion.
+
+   1. Source Code.
+
+The "source code" for a work means the preferred form of the work for making
+modifications to it. "Object code" means any non-source form of a work.
+
+A "Standard Interface" means an interface that either is an official standard
+defined by a recognized standards body, or, in the case of interfaces specified
+for a particular programming language, one that is widely used among developers
+working in that language.
+
+The "System Libraries" of an executable work include anything, other than
+the work as a whole, that (a) is included in the normal form of packaging
+a Major Component, but which is not part of that Major Component, and (b)
+serves only to enable use of the work with that Major Component, or to implement
+a Standard Interface for which an implementation is available to the public
+in source code form. A "Major Component", in this context, means a major essential
+component (kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to produce
+the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all the source
+code needed to generate, install, and (for an executable work) run the object
+code and to modify the work, including scripts to control those activities.
+However, it does not include the work's System Libraries, or general-purpose
+tools or generally available free programs which are used unmodified in performing
+those activities but which are not part of the work. For example, Corresponding
+Source includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically linked
+subprograms that the work is specifically designed to require, such as by
+intimate data communication or control flow between those subprograms and
+other parts of the work.
+
+The Corresponding Source need not include anything that users can regenerate
+automatically from other parts of the Corresponding Source.
+
+   The Corresponding Source for a work in source code form is that same work.
+
+   2. Basic Permissions.
+
+All rights granted under this License are granted for the term of copyright
+on the Program, and are irrevocable provided the stated conditions are met.
+This License explicitly affirms your unlimited permission to run the unmodified
+Program. The output from running a covered work is covered by this License
+only if the output, given its content, constitutes a covered work. This License
+acknowledges your rights of fair use or other equivalent, as provided by copyright
+law.
+
+You may make, run and propagate covered works that you do not convey, without
+conditions so long as your license otherwise remains in force. You may convey
+covered works to others for the sole purpose of having them make modifications
+exclusively for you, or provide you with facilities for running those works,
+provided that you comply with the terms of this License in conveying all material
+for which you do not control copyright. Those thus making or running the covered
+works for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of your copyrighted
+material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the conditions
+stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
+
+   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological measure
+under any applicable law fulfilling obligations under article 11 of the WIPO
+copyright treaty adopted on 20 December 1996, or similar laws prohibiting
+or restricting circumvention of such measures.
+
+When you convey a covered work, you waive any legal power to forbid circumvention
+of technological measures to the extent such circumvention is effected by
+exercising rights under this License with respect to the covered work, and
+you disclaim any intention to limit operation or modification of the work
+as a means of enforcing, against the work's users, your or third parties'
+legal rights to forbid circumvention of technological measures.
+
+   4. Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you receive
+it, in any medium, provided that you conspicuously and appropriately publish
+on each copy an appropriate copyright notice; keep intact all notices stating
+that this License and any non-permissive terms added in accord with section
+7 apply to the code; keep intact all notices of the absence of any warranty;
+and give all recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey, and you
+may offer support or warranty protection for a fee.
+
+   5. Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to produce
+it from the Program, in the form of source code under the terms of section
+4, provided that you also meet all of these conditions:
+
+a) The work must carry prominent notices stating that you modified it, and
+giving a relevant date.
+
+b) The work must carry prominent notices stating that it is released under
+this License and any conditions added under section 7. This requirement modifies
+the requirement in section 4 to "keep intact all notices".
+
+c) You must license the entire work, as a whole, under this License to anyone
+who comes into possession of a copy. This License will therefore apply, along
+with any applicable section 7 additional terms, to the whole of the work,
+and all its parts, regardless of how they are packaged. This License gives
+no permission to license the work in any other way, but it does not invalidate
+such permission if you have separately received it.
+
+d) If the work has interactive user interfaces, each must display Appropriate
+Legal Notices; however, if the Program has interactive interfaces that do
+not display Appropriate Legal Notices, your work need not make them do so.
+
+A compilation of a covered work with other separate and independent works,
+which are not by their nature extensions of the covered work, and which are
+not combined with it such as to form a larger program, in or on a volume of
+a storage or distribution medium, is called an "aggregate" if the compilation
+and its resulting copyright are not used to limit the access or legal rights
+of the compilation's users beyond what the individual works permit. Inclusion
+of a covered work in an aggregate does not cause this License to apply to
+the other parts of the aggregate.
+
+   6. Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of sections
+4 and 5, provided that you also convey the machine-readable Corresponding
+Source under the terms of this License, in one of these ways:
+
+a) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by the Corresponding Source fixed
+on a durable physical medium customarily used for software interchange.
+
+b) Convey the object code in, or embodied in, a physical product (including
+a physical distribution medium), accompanied by a written offer, valid for
+at least three years and valid for as long as you offer spare parts or customer
+support for that product model, to give anyone who possesses the object code
+either (1) a copy of the Corresponding Source for all the software in the
+product that is covered by this License, on a durable physical medium customarily
+used for software interchange, for a price no more than your reasonable cost
+of physically performing this conveying of source, or (2) access to copy the
+Corresponding Source from a network server at no charge.
+
+c) Convey individual copies of the object code with a copy of the written
+offer to provide the Corresponding Source. This alternative is allowed only
+occasionally and noncommercially, and only if you received the object code
+with such an offer, in accord with subsection 6b.
+
+d) Convey the object code by offering access from a designated place (gratis
+or for a charge), and offer equivalent access to the Corresponding Source
+in the same way through the same place at no further charge. You need not
+require recipients to copy the Corresponding Source along with the object
+code. If the place to copy the object code is a network server, the Corresponding
+Source may be on a different server (operated by you or a third party) that
+supports equivalent copying facilities, provided you maintain clear directions
+next to the object code saying where to find the Corresponding Source. Regardless
+of what server hosts the Corresponding Source, you remain obligated to ensure
+that it is available for as long as needed to satisfy these requirements.
+
+e) Convey the object code using peer-to-peer transmission, provided you inform
+other peers where the object code and Corresponding Source of the work are
+being offered to the general public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded from
+the Corresponding Source as a System Library, need not be included in conveying
+the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any tangible
+personal property which is normally used for personal, family, or household
+purposes, or (2) anything designed or sold for incorporation into a dwelling.
+In determining whether a product is a consumer product, doubtful cases shall
+be resolved in favor of coverage. For a particular product received by a particular
+user, "normally used" refers to a typical or common use of that class of product,
+regardless of the status of the particular user or of the way in which the
+particular user actually uses, or expects or is expected to use, the product.
+A product is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent the
+only significant mode of use of the product.
+
+"Installation Information" for a User Product means any methods, procedures,
+authorization keys, or other information required to install and execute modified
+versions of a covered work in that User Product from a modified version of
+its Corresponding Source. The information must suffice to ensure that the
+continued functioning of the modified object code is in no case prevented
+or interfered with solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or specifically
+for use in, a User Product, and the conveying occurs as part of a transaction
+in which the right of possession and use of the User Product is transferred
+to the recipient in perpetuity or for a fixed term (regardless of how the
+transaction is characterized), the Corresponding Source conveyed under this
+section must be accompanied by the Installation Information. But this requirement
+does not apply if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has been installed
+in ROM).
+
+The requirement to provide Installation Information does not include a requirement
+to continue to provide support service, warranty, or updates for a work that
+has been modified or installed by the recipient, or for the User Product in
+which it has been modified or installed. Access to a network may be denied
+when the modification itself materially and adversely affects the operation
+of the network or violates the rules and protocols for communication across
+the network.
+
+Corresponding Source conveyed, and Installation Information provided, in accord
+with this section must be in a format that is publicly documented (and with
+an implementation available to the public in source code form), and must require
+no special password or key for unpacking, reading or copying.
+
+   7. Additional Terms.
+
+"Additional permissions" are terms that supplement the terms of this License
+by making exceptions from one or more of its conditions. Additional permissions
+that are applicable to the entire Program shall be treated as though they
+were included in this License, to the extent that they are valid under applicable
+law. If additional permissions apply only to part of the Program, that part
+may be used separately under those permissions, but the entire Program remains
+governed by this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option remove any
+additional permissions from that copy, or from any part of it. (Additional
+permissions may be written to require their own removal in certain cases when
+you modify the work.) You may place additional permissions on material, added
+by you to a covered work, for which you have or can give appropriate copyright
+permission.
+
+Notwithstanding any other provision of this License, for material you add
+to a covered work, you may (if authorized by the copyright holders of that
+material) supplement the terms of this License with terms:
+
+a) Disclaiming warranty or limiting liability differently from the terms of
+sections 15 and 16 of this License; or
+
+b) Requiring preservation of specified reasonable legal notices or author
+attributions in that material or in the Appropriate Legal Notices displayed
+by works containing it; or
+
+c) Prohibiting misrepresentation of the origin of that material, or requiring
+that modified versions of such material be marked in reasonable ways as different
+from the original version; or
+
+d) Limiting the use for publicity purposes of names of licensors or authors
+of the material; or
+
+e) Declining to grant rights under trademark law for use of some trade names,
+trademarks, or service marks; or
+
+f) Requiring indemnification of licensors and authors of that material by
+anyone who conveys the material (or modified versions of it) with contractual
+assumptions of liability to the recipient, for any liability that these contractual
+assumptions directly impose on those licensors and authors.
+
+All other non-permissive additional terms are considered "further restrictions"
+within the meaning of section 10. If the Program as you received it, or any
+part of it, contains a notice stating that it is governed by this License
+along with a term that is a further restriction, you may remove that term.
+If a license document contains a further restriction but permits relicensing
+or conveying under this License, you may add to a covered work material governed
+by the terms of that license document, provided that the further restriction
+does not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you must place,
+in the relevant source files, a statement of the additional terms that apply
+to those files, or a notice indicating where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the form
+of a separately written license, or stated as exceptions; the above requirements
+apply either way.
+
+   8. Termination.
+
+You may not propagate or modify a covered work except as expressly provided
+under this License. Any attempt otherwise to propagate or modify it is void,
+and will automatically terminate your rights under this License (including
+any patent licenses granted under the third paragraph of section 11).
+
+However, if you cease all violation of this License, then your license from
+a particular copyright holder is reinstated (a) provisionally, unless and
+until the copyright holder explicitly and finally terminates your license,
+and (b) permanently, if the copyright holder fails to notify you of the violation
+by some reasonable means prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is reinstated permanently
+if the copyright holder notifies you of the violation by some reasonable means,
+this is the first time you have received notice of violation of this License
+(for any work) from that copyright holder, and you cure the violation prior
+to 30 days after your receipt of the notice.
+
+Termination of your rights under this section does not terminate the licenses
+of parties who have received copies or rights from you under this License.
+If your rights have been terminated and not permanently reinstated, you do
+not qualify to receive new licenses for the same material under section 10.
+
+   9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run a copy
+of the Program. Ancillary propagation of a covered work occurring solely as
+a consequence of using peer-to-peer transmission to receive a copy likewise
+does not require acceptance. However, nothing other than this License grants
+you permission to propagate or modify any covered work. These actions infringe
+copyright if you do not accept this License. Therefore, by modifying or propagating
+a covered work, you indicate your acceptance of this License to do so.
+
+   10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically receives
+a license from the original licensors, to run, modify and propagate that work,
+subject to this License. You are not responsible for enforcing compliance
+by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an organization,
+or substantially all assets of one, or subdividing an organization, or merging
+organizations. If propagation of a covered work results from an entity transaction,
+each party to that transaction who receives a copy of the work also receives
+whatever licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the Corresponding
+Source of the work from the predecessor in interest, if the predecessor has
+it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the rights
+granted or affirmed under this License. For example, you may not impose a
+license fee, royalty, or other charge for exercise of rights granted under
+this License, and you may not initiate litigation (including a cross-claim
+or counterclaim in a lawsuit) alleging that any patent claim is infringed
+by making, using, selling, offering for sale, or importing the Program or
+any portion of it.
+
+   11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this License
+of the Program or a work on which the Program is based. The work thus licensed
+is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims owned or controlled
+by the contributor, whether already acquired or hereafter acquired, that would
+be infringed by some manner, permitted by this License, of making, using,
+or selling its contributor version, but do not include claims that would be
+infringed only as a consequence of further modification of the contributor
+version. For purposes of this definition, "control" includes the right to
+grant patent sublicenses in a manner consistent with the requirements of this
+License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free patent
+license under the contributor's essential patent claims, to make, use, sell,
+offer for sale, import and otherwise run, modify and propagate the contents
+of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express agreement
+or commitment, however denominated, not to enforce a patent (such as an express
+permission to practice a patent or covenant not to sue for patent infringement).
+To "grant" such a patent license to a party means to make such an agreement
+or commitment not to enforce a patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license, and the
+Corresponding Source of the work is not available for anyone to copy, free
+of charge and under the terms of this License, through a publicly available
+network server or other readily accessible means, then you must either (1)
+cause the Corresponding Source to be so available, or (2) arrange to deprive
+yourself of the benefit of the patent license for this particular work, or
+(3) arrange, in a manner consistent with the requirements of this License,
+to extend the patent license to downstream recipients. "Knowingly relying"
+means you have actual knowledge that, but for the patent license, your conveying
+the covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that country
+that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or arrangement,
+you convey, or propagate by procuring conveyance of, a covered work, and grant
+a patent license to some of the parties receiving the covered work authorizing
+them to use, propagate, modify or convey a specific copy of the covered work,
+then the patent license you grant is automatically extended to all recipients
+of the covered work and works based on it.
+
+A patent license is "discriminatory" if it does not include within the scope
+of its coverage, prohibits the exercise of, or is conditioned on the non-exercise
+of one or more of the rights that are specifically granted under this License.
+You may not convey a covered work if you are a party to an arrangement with
+a third party that is in the business of distributing software, under which
+you make payment to the third party based on the extent of your activity of
+conveying the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by you
+(or copies made from those copies), or (b) primarily for and in connection
+with specific products or compilations that contain the covered work, unless
+you entered into that arrangement, or that patent license was granted, prior
+to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting any implied
+license or other defenses to infringement that may otherwise be available
+to you under applicable patent law.
+
+   12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or otherwise)
+that contradict the conditions of this License, they do not excuse you from
+the conditions of this License. If you cannot convey a covered work so as
+to satisfy simultaneously your obligations under this License and any other
+pertinent obligations, then as a consequence you may not convey it at all.
+For example, if you agree to terms that obligate you to collect a royalty
+for further conveying from those to whom you convey the Program, the only
+way you could satisfy both those terms and this License would be to refrain
+entirely from conveying the Program.
+
+   13. Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have permission to
+link or combine any covered work with a work licensed under version 3 of the
+GNU Affero General Public License into a single combined work, and to convey
+the resulting work. The terms of this License will continue to apply to the
+part which is the covered work, but the special requirements of the GNU Affero
+General Public License, section 13, concerning interaction through a network
+will apply to the combination as such.
+
+   14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions of the
+GNU General Public License from time to time. Such new versions will be similar
+in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies
+that a certain numbered version of the GNU General Public License "or any
+later version" applies to it, you have the option of following the terms and
+conditions either of that numbered version or of any later version published
+by the Free Software Foundation. If the Program does not specify a version
+number of the GNU General Public License, you may choose any version ever
+published by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions of
+the GNU General Public License can be used, that proxy's public statement
+of acceptance of a version permanently authorizes you to choose that version
+for the Program.
+
+Later license versions may give you additional or different permissions. However,
+no additional obligations are imposed on any author or copyright holder as
+a result of your choosing to follow a later version.
+
+   15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
+LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
+OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
+PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+   16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
+ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM
+AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
+USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
+PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+   17. Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided above cannot
+be given local legal effect according to their terms, reviewing courts shall
+apply local law that most closely approximates an absolute waiver of all civil
+liability in connection with the Program, unless a warranty or assumption
+of liability accompanies a copy of the Program in return for a fee. END OF
+TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible
+use to the public, the best way to achieve this is to make it free software
+which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach
+them to the start of each source file to most effectively state the exclusion
+of warranty; and each file should have at least the "copyright" line and a
+pointer to where the full notice is found.
+
+<one line to give the program's name and a brief idea of what it does.>
+
+Copyright (C) <year> <name of author>
+
+This program is free software: you can redistribute it and/or modify it under
+the terms of the GNU General Public License as published by the Free Software
+Foundation, either version 3 of the License, or (at your option) any later
+version.
+
+This program is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
+FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
+
+You should have received a copy of the GNU General Public License along with
+this program. If not, see <http s ://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program does terminal interaction, make it output a short notice like
+this when it starts in an interactive mode:
+
+<program> Copyright (C) <year> <name of author>
+
+This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+
+This is free software, and you are welcome to redistribute it under certain
+conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands might
+be different; for a GUI interface, you would use an "about box".
+
+You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary. For
+more information on this, and how to apply and follow the GNU GPL, see <http
+s ://www.gnu.org/licenses/>.
+
+The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General Public
+License instead of this License. But first, please read <http s ://www.gnu.org/
+licenses /why-not-lgpl.html>.
