+### GNU GENERAL PUBLIC LICENSE
-_Version 3, 29 June 2007_
-_Copyright © 2007 Free Software Foundation, Inc. <>_
+Version 2, June 1991
-Everyone is permitted to copy and distribute verbatim copies of this license
-document, but changing it is not allowed.
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
-## Preamble
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
-The GNU General Public License is a free, copyleft license for software and other
-kinds of works.
+### Preamble
-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
+The licenses for most software are designed to take away your freedom
+to share and change it. By contrast, the GNU General Public License is
+intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) 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.

- Copyright (C)
-
- 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.
+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
+this service 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 make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if
+you distribute copies of the software, or if you modify it.
+
+For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. 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.
+
+We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on,
+we want its recipients to know that what they have is not the
+original, so that any problems introduced by others will not reflect
+on the original authors' reputations.
+
+Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at
+all.
+
+The precise terms and conditions for copying, distribution and
+modification follow.
+
+### TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+**0.** This License applies to any program or other work which
+contains a notice placed by the copyright holder saying it may be
+distributed under the terms of this General Public License. The
+"Program", below, refers to any such program or work, and a "work
+based on the Program" means either the Program or any derivative work
+under copyright law: that is to say, a work containing the Program or
+a portion of it, either verbatim or with modifications and/or
+translated into another language. (Hereinafter, translation is
+included without limitation in the term "modification".) Each licensee
+is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the Program
+(independent of having been made by running the Program). Whether that
+is true depends on what the Program does.
+
+**1.** You may copy and distribute 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 and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a
+fee.
+
+**2.** You may modify your copy or copies of the Program or any
+portion of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+
+**a)** You must cause the modified files to carry prominent notices
+stating that you changed the files and the date of any change.
+
+
+**b)** You must cause any work that you distribute or publish, that in
+whole or in part contains or is derived from the Program or any part
+thereof, to be licensed as a whole at no charge to all third parties
+under the terms of this License.
+
+
+**c)** If the modified program normally reads commands interactively
+when run, you must cause it, when started running for such interactive
+use in the most ordinary way, to print or display an announcement
+including an appropriate copyright notice and a notice that there is
+no warranty (or else, saying that you provide a warranty) and that
+users may redistribute the program under these conditions, and telling
+the user how to view a copy of this License. (Exception: if the
+Program itself is interactive but does not normally print such an
+announcement, your work based on the Program is not required to print
+an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+**3.** You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+
+**a)** Accompany it with the complete corresponding machine-readable
+source code, which must be distributed under the terms of Sections 1
+and 2 above on a medium customarily used for software interchange; or,
+
+
+**b)** Accompany it with a written offer, valid for at least three
+years, to give any third party, for a charge no more than your cost of
+physically performing source distribution, a complete machine-readable
+copy of the corresponding source code, to be distributed under the
+terms of Sections 1 and 2 above on a medium customarily used for
+software interchange; or,
+
+
+**c)** Accompany it with the information you received as to the offer
+to distribute corresponding source code. (This alternative is allowed
+only for noncommercial distribution and only if you received the
+program in object code or executable form with such an offer, in
+accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+**4.** You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt otherwise
+to copy, modify, sublicense or distribute the Program is void, and
+will automatically terminate your rights under this License. However,
+parties who have received copies, or rights, from you under this
+License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+**5.** You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+**6.** Each time you redistribute the Program (or any work based on
+the Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+**7.** If, as a consequence of a court judgment or allegation of
+patent infringement or for any other reason (not limited to patent
+issues), 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 distribute so as to satisfy simultaneously your
+obligations under this License and any other pertinent obligations,
+then as a consequence you may not distribute the Program at all. For
+example, if a patent license would not permit royalty-free
+redistribution of the Program by all those who receive copies directly
+or indirectly through you, then the only way you could satisfy both it
+and this License would be to refrain entirely from distribution of the
+Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+**8.** If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+**9.** The Free Software Foundation may publish revised and/or new
+versions of the 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 a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Program does not specify a
+version number of this License, you may choose any version ever
+published by the Free Software Foundation.
+
+**10.** If you wish to incorporate parts of the Program into other
+free programs whose distribution conditions are different, write to
+the author to ask for permission. For software which is copyrighted by
+the Free Software Foundation, write to the Free Software Foundation;
+we sometimes make exceptions for this. Our decision will be guided by
+the two goals of preserving the free status of all derivatives of our
+free software and of promoting the sharing and reuse of software
+generally.
+
+**NO WARRANTY**
+
+**11.** BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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.
+
+**12.** IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE 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.
