+GNU GENERAL PUBLIC LICENSE
+
+Version 3, 29 June 2007
+
+Copyright © 2007
+aet
+
+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) 2022 <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
+<https://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) 2022 <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
+<https://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
+<https://www.gnu.org/ licenses /why-not-lgpl.html>.
