2737N/AEveryone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
2737N/APreamble
2737N/AThe GNU General Public License is a free, copyleft license for software and other kinds of works.
2737N/AThe 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.
2737N/AWhen 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.
2737N/ATo 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.
2737N/AFor 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.
2737N/ADevelopers 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.
2737N/AFor 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.
2737N/ASome 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.
2737N/AFinally, 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.
2737N/AThe precise terms and conditions for copying, distribution and modification follow.
2737N/ATERMS AND CONDITIONS
2737N/A0. Definitions.
2737N/A“This License” refers to version 3 of the GNU General Public License.
2737N/A“Copyright” also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.
2737N/A“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.
2737N/ATo “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.
2737N/AA “covered work” means either the unmodified Program or a work based on the Program.
2737N/ATo “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.
2737N/ATo “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.
2737N/AAn 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.
2737N/A1. Source Code.
2737N/AThe “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.
2737N/AA “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.
2737N/AThe “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.
2737N/AThe “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.
2737N/AThe Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.
2737N/AThe Corresponding Source for a work in source code form is that same work.
2737N/A2. Basic Permissions.
2737N/AAll 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.
2737N/AYou 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.
2737N/AConveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
2737N/A3. Protecting Users' Legal Rights From Anti-Circumvention Law.
2737N/ANo 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.
2737N/AWhen 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.
2737N/A4. Conveying Verbatim Copies.
2737N/AYou 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.
2737N/AYou may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.
2737N/A5. Conveying Modified Source Versions.
2737N/AYou 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:
2737N/Aa) The work must carry prominent notices stating that you modified it, and giving a relevant date.
2737N/Ab) 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”.
2737N/Ac) 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.
2737N/Ad) 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.
2737N/AA 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.
2737N/A6. Conveying Non-Source Forms.
2737N/AYou 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:
2737N/Aa) 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.
2737N/Ab) 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.
2737N/Ac) 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.
2737N/Ad) 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.
2737N/Ae) 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.
2737N/AA 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.
2737N/AA “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.
2737N/A“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.
2737N/AIf 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).
2737N/AThe 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.
2737N/ACorresponding 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.
2737N/A7. Additional Terms.
2737N/A“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.
2737N/AWhen 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.
2737N/ANotwithstanding 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:
2737N/Aa) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or
2737N/Ab) 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
2737N/Ac) 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
2737N/Ad) Limiting the use for publicity purposes of names of licensors or authors of the material; or
2737N/Ae) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or
2737N/Af) 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.
2737N/AAll 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.
2737N/AIf 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.
2737N/AAdditional 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.
2737N/A8. Termination.
2737N/AYou 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).
2737N/AHowever, 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.
2737N/AMoreover, 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.
2737N/ATermination 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.
2737N/A9. Acceptance Not Required for Having Copies.
2737N/AYou 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.
2737N/A10. Automatic Licensing of Downstream Recipients.
2737N/AEach 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.
2737N/AAn “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.
2737N/AYou 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.
2737N/A11. Patents.
2737N/AA “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”.
2737N/AA 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.
2737N/AEach 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.
2737N/AIn 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.
2737N/AIf 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.
2737N/AIf, 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.
2737N/AA 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.
2737N/ANothing 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.
2737N/A12. No Surrender of Others' Freedom.
2737N/AIf 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.
2737N/A13. Use with the GNU Affero General Public License.
2737N/ANotwithstanding 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.
2737N/A14. Revised Versions of this License.
2737N/AThe 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.
2737N/AEach 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.
2737N/AIf 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.
2737N/ALater 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.
2737N/A15. Disclaimer of Warranty.
2737N/ATHERE 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.
2737N/A16. Limitation of Liability.
2737N/AIN 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.
2737N/A17. Interpretation of Sections 15 and 16.
2737N/AIf 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.

2737N/AEveryone is permitted to copy and distribute verbatim copies
2737N/Aof this license document, but changing it is not allowed.
631N/A
631N/A0. PREAMBLE
631N/A
631N/AThe purpose of this License is to make a manual, textbook, or other
631N/Afunctional and useful document "free" in the sense of freedom: to
631N/Aassure everyone the effective freedom to copy and redistribute it,
631N/Awith or without modifying it, either commercially or noncommercially.
631N/ASecondarily, this License preserves for the author and publisher a way
631N/Ato get credit for their work, while not being considered responsible
631N/Afor modifications made by others.
631N/A
631N/AThis License is a kind of "copyleft", which means that derivative
2737N/Aworks of the document must themselves be free in the same sense. It
631N/Acomplements the GNU General Public License, which is a copyleft
631N/Alicense designed for free software.
631N/A
631N/AWe have designed this License in order to use it for manuals for free
631N/Asoftware, because free software needs free documentation: a free
631N/Aprogram should come with manuals providing the same freedoms that the
2737N/Asoftware does. But this License is not limited to software manuals;
631N/Ait can be used for any textual work, regardless of subject matter or
2737N/Awhether it is published as a printed book. We recommend this License
631N/Aprincipally for works whose purpose is instruction or reference.
631N/A
631N/A
631N/A1. APPLICABILITY AND DEFINITIONS
631N/A
631N/AThis License applies to any manual or other work, in any medium, that
631N/Acontains a notice placed by the copyright holder saying it can be
2737N/Adistributed under the terms of this License. Such a notice grants a
631N/Aworld-wide, royalty-free license, unlimited in duration, to use that
2737N/Awork under the conditions stated herein. The "Document", below,
2737N/Arefers to any such manual or work. Any member of the public is a
2737N/Alicensee, and is addressed as "you". You accept the license if you
631N/Acopy, modify or distribute the work in a way requiring permission
631N/Aunder copyright law.
631N/A
631N/AA "Modified Version" of the Document means any work containing the
631N/ADocument or a portion of it, either copied verbatim, or with
631N/Amodifications and/or translated into another language.
631N/A
631N/AA "Secondary Section" is a named appendix or a front-matter section of
631N/Athe Document that deals exclusively with the relationship of the
631N/Apublishers or authors of the Document to the Document's overall
631N/Asubject (or to related matters) and contains nothing that could fall
2737N/Adirectly within that overall subject. (Thus, if the Document is in
631N/Apart a textbook of mathematics, a Secondary Section may not explain
2737N/Aany mathematics.) The relationship could be a matter of historical
631N/Aconnection with the subject or with related matters, or of legal,
631N/Acommercial, philosophical, ethical or political position regarding
631N/Athem.
631N/A
631N/AThe "Invariant Sections" are certain Secondary Sections whose titles
631N/Aare designated, as being those of Invariant Sections, in the notice
2737N/Athat says that the Document is released under this License. If a
631N/Asection does not fit the above definition of Secondary then it is not
2737N/Aallowed to be designated as Invariant. The Document may contain zero
2737N/AInvariant Sections. If the Document does not identify any Invariant
631N/ASections then there are none.
631N/A
631N/AThe "Cover Texts" are certain short passages of text that are listed,
631N/Aas Front-Cover Texts or Back-Cover Texts, in the notice that says that
2737N/Athe Document is released under this License. A Front-Cover Text may
631N/Abe at most 5 words, and a Back-Cover Text may be at most 25 words.
631N/A
631N/AA "Transparent" copy of the Document means a machine-readable copy,
631N/Arepresented in a format whose specification is available to the
631N/Ageneral public, that is suitable for revising the document
631N/Astraightforwardly with generic text editors or (for images composed of
631N/Apixels) generic paint programs or (for drawings) some widely available
631N/Adrawing editor, and that is suitable for input to text formatters or
631N/Afor automatic translation to a variety of formats suitable for input
2737N/Ato text formatters. A copy made in an otherwise Transparent file
631N/Aformat whose markup, or absence of markup, has been arranged to thwart
631N/Aor discourage subsequent modification by readers is not Transparent.
631N/AAn image format is not Transparent if used for any substantial amount
2737N/Aof text. A copy that is not "Transparent" is called "Opaque".
631N/A
631N/AExamples of suitable formats for Transparent copies include plain
631N/AASCII without markup, Texinfo input format, LaTeX input format, SGML
631N/Aor XML using a publicly available DTD, and standard-conforming simple
2737N/AHTML, PostScript or PDF designed for human modification. Examples of
2737N/Atransparent image formats include PNG, XCF and JPG. Opaque formats
631N/Ainclude proprietary formats that can be read and edited only by
631N/Aproprietary word processors, SGML or XML for which the DTD and/or
631N/Aprocessing tools are not generally available, and the
631N/Amachine-generated HTML, PostScript or PDF produced by some word
631N/Aprocessors for output purposes only.
631N/A
631N/AThe "Title Page" means, for a printed book, the title page itself,
631N/Aplus such following pages as are needed to hold, legibly, the material
2737N/Athis License requires to appear in the title page. For works in
631N/Aformats which do not have any title page as such, "Title Page" means
631N/Athe text near the most prominent appearance of the work's title,
631N/Apreceding the beginning of the body of the text.
631N/A
631N/AThe "publisher" means any person or entity that distributes copies of
631N/Athe Document to the public.
631N/A
631N/AA section "Entitled XYZ" means a named subunit of the Document whose
631N/Atitle either is precisely XYZ or contains XYZ in parentheses following
2737N/Atext that translates XYZ in another language. (Here XYZ stands for a
631N/Aspecific section name mentioned below, such as "Acknowledgements",
2737N/A"Dedications", "Endorsements", or "History".) To "Preserve the Title"
631N/Aof such a section when you modify the Document means that it remains a
631N/Asection "Entitled XYZ" according to this definition.
631N/A
631N/AThe Document may include Warranty Disclaimers next to the notice which
2737N/Astates that this License applies to the Document. These Warranty
631N/ADisclaimers are considered to be included by reference in this
631N/ALicense, but only as regards disclaiming warranties: any other
631N/Aimplication that these Warranty Disclaimers may have is void and has
631N/Ano effect on the meaning of this License.
631N/A
631N/A2. VERBATIM COPYING
631N/A
631N/AYou may copy and distribute the Document in any medium, either
631N/Acommercially or noncommercially, provided that this License, the
631N/Acopyright notices, and the license notice saying this License applies
631N/Ato the Document are reproduced in all copies, and that you add no
2737N/Aother conditions whatsoever to those of this License. You may not use
631N/Atechnical measures to obstruct or control the reading or further
2737N/Acopying of the copies you make or distribute. However, you may accept
2737N/Acompensation in exchange for copies. If you distribute a large enough
631N/Anumber of copies you must also follow the conditions in section 3.
631N/A
631N/AYou may also lend copies, under the same conditions stated above, and
631N/Ayou may publicly display copies.
631N/A
631N/A
631N/A3. COPYING IN QUANTITY
631N/A
631N/AIf you publish printed copies (or copies in media that commonly have
631N/Aprinted covers) of the Document, numbering more than 100, and the
631N/ADocument's license notice requires Cover Texts, you must enclose the
631N/Acopies in covers that carry, clearly and legibly, all these Cover
631N/ATexts: Front-Cover Texts on the front cover, and Back-Cover Texts on
2737N/Athe back cover. Both covers must also clearly and legibly identify
2737N/Ayou as the publisher of these copies. The front cover must present
631N/Athe full title with all words of the title equally prominent and
2737N/Avisible. You may add other material on the covers in addition.
631N/ACopying with changes limited to the covers, as long as they preserve
631N/Athe title of the Document and satisfy these conditions, can be treated
631N/Aas verbatim copying in other respects.
631N/A
631N/AIf the required texts for either cover are too voluminous to fit
631N/Alegibly, you should put the first ones listed (as many as fit
631N/Areasonably) on the actual cover, and continue the rest onto adjacent
631N/Apages.
631N/A
631N/AIf you publish or distribute Opaque copies of the Document numbering
631N/Amore than 100, you must either include a machine-readable Transparent
631N/Acopy along with each Opaque copy, or state in or with each Opaque copy
631N/Aa computer-network location from which the general network-using
631N/Apublic has access to download using public-standard network protocols
631N/Aa complete Transparent copy of the Document, free of added material.
631N/AIf you use the latter option, you must take reasonably prudent steps,
631N/Awhen you begin distribution of Opaque copies in quantity, to ensure
631N/Athat this Transparent copy will remain thus accessible at the stated
631N/Alocation until at least one year after the last time you distribute an
631N/AOpaque copy (directly or through your agents or retailers) of that
631N/Aedition to the public.
631N/A
631N/AIt is requested, but not required, that you contact the authors of the
631N/ADocument well before redistributing any large number of copies, to
631N/Agive them a chance to provide you with an updated version of the
631N/ADocument.
631N/A
631N/A
631N/A4. MODIFICATIONS
631N/A
631N/AYou may copy and distribute a Modified Version of the Document under
631N/Athe conditions of sections 2 and 3 above, provided that you release
631N/Athe Modified Version under precisely this License, with the Modified
631N/AVersion filling the role of the Document, thus licensing distribution
631N/Aand modification of the Modified Version to whoever possesses a copy
2737N/Aof it. In addition, you must do these things in the Modified Version:
631N/A
631N/AA. Use in the Title Page (and on the covers, if any) a title distinct
2737N/Afrom that of the Document, and from those of previous versions
2737N/A(which should, if there were any, be listed in the History section
2737N/Aof the Document). You may use the same title as a previous version
2737N/Aif the original publisher of that version gives permission.
631N/AB. List on the Title Page, as authors, one or more persons or entities
2737N/Aresponsible for authorship of the modifications in the Modified
2737N/AVersion, together with at least five of the principal authors of the
2737N/ADocument (all of its principal authors, if it has fewer than five),
2737N/Aunless they release you from this requirement.
631N/AC. State on the Title page the name of the publisher of the
2737N/AModified Version, as the publisher.
631N/AD. Preserve all the copyright notices of the Document.
631N/AE. Add an appropriate copyright notice for your modifications
2737N/Aadjacent to the other copyright notices.
631N/AF. Include, immediately after the copyright notices, a license notice
2737N/Agiving the public permission to use the Modified Version under the
2737N/Aterms of this License, in the form shown in the Addendum below.
631N/AG. Preserve in that license notice the full lists of Invariant Sections
2737N/Aand required Cover Texts given in the Document's license notice.
631N/AH. Include an unaltered copy of this License.
631N/AI. Preserve the section Entitled "History", Preserve its Title, and add
2737N/Ato it an item stating at least the title, year, new authors, and
2737N/Apublisher of the Modified Version as given on the Title Page. If
2737N/Athere is no section Entitled "History" in the Document, create one
2737N/Astating the title, year, authors, and publisher of the Document as
2737N/Agiven on its Title Page, then add an item describing the Modified
2737N/AVersion as stated in the previous sentence.
631N/AJ. Preserve the network location, if any, given in the Document for
2737N/Apublic access to a Transparent copy of the Document, and likewise
2737N/Athe network locations given in the Document for previous versions
2737N/Ait was based on. These may be placed in the "History" section.
2737N/AYou may omit a network location for a work that was published at
2737N/Aleast four years before the Document itself, or if the original
2737N/Apublisher of the version it refers to gives permission.
631N/AK. For any section Entitled "Acknowledgements" or "Dedications",
2737N/APreserve the Title of the section, and preserve in the section all
2737N/Athe substance and tone of each of the contributor acknowledgements
2737N/Aand/or dedications given therein.
631N/AL. Preserve all the Invariant Sections of the Document,
2737N/Aunaltered in their text and in their titles. Section numbers
2737N/Aor the equivalent are not considered part of the section titles.
2737N/AM. Delete any section Entitled "Endorsements". Such a section
2737N/Amay not be included in the Modified Version.
631N/AN. Do not retitle any existing section to be Entitled "Endorsements"
2737N/Aor to conflict in title with any Invariant Section.
631N/AO. Preserve any Warranty Disclaimers.
631N/A
631N/AIf the Modified Version includes new front-matter sections or
631N/Aappendices that qualify as Secondary Sections and contain no material
631N/Acopied from the Document, you may at your option designate some or all
2737N/Aof these sections as invariant. To do this, add their titles to the
631N/Alist of Invariant Sections in the Modified Version's license notice.
631N/AThese titles must be distinct from any other section titles.
631N/A
631N/AYou may add a section Entitled "Endorsements", provided it contains
631N/Anothing but endorsements of your Modified Version by various
631N/Aparties--for example, statements of peer review or that the text has
631N/Abeen approved by an organization as the authoritative definition of a
631N/Astandard.
631N/A
631N/AYou may add a passage of up to five words as a Front-Cover Text, and a
631N/Apassage of up to 25 words as a Back-Cover Text, to the end of the list
2737N/Aof Cover Texts in the Modified Version. Only one passage of
631N/AFront-Cover Text and one of Back-Cover Text may be added by (or
2737N/Athrough arrangements made by) any one entity. If the Document already
631N/Aincludes a cover text for the same cover, previously added by you or
631N/Aby arrangement made by the same entity you are acting on behalf of,
631N/Ayou may not add another; but you may replace the old one, on explicit
631N/Apermission from the previous publisher that added the old one.
631N/A
631N/AThe author(s) and publisher(s) of the Document do not by this License
631N/Agive permission to use their names for publicity for or to assert or
631N/Aimply endorsement of any Modified Version.
631N/A
631N/A
631N/A5. COMBINING DOCUMENTS
631N/A
631N/AYou may combine the Document with other documents released under this
631N/ALicense, under the terms defined in section 4 above for modified
631N/Aversions, provided that you include in the combination all of the
631N/AInvariant Sections of all of the original documents, unmodified, and
631N/Alist them all as Invariant Sections of your combined work in its
631N/Alicense notice, and that you preserve all their Warranty Disclaimers.
631N/A
631N/AThe combined work need only contain one copy of this License, and
631N/Amultiple identical Invariant Sections may be replaced with a single
2737N/Acopy. If there are multiple Invariant Sections with the same name but
631N/Adifferent contents, make the title of each such section unique by
631N/Aadding at the end of it, in parentheses, the name of the original
631N/Aauthor or publisher of that section if known, or else a unique number.
631N/AMake the same adjustment to the section titles in the list of
631N/AInvariant Sections in the license notice of the combined work.
631N/A
631N/AIn the combination, you must combine any sections Entitled "History"
631N/Ain the various original documents, forming one section Entitled
631N/A"History"; likewise combine any sections Entitled "Acknowledgements",
2737N/Aand any sections Entitled "Dedications". You must delete all sections
631N/AEntitled "Endorsements".
631N/A
631N/A
631N/A6. COLLECTIONS OF DOCUMENTS
631N/A
631N/AYou may make a collection consisting of the Document and other
631N/Adocuments released under this License, and replace the individual
631N/Acopies of this License in the various documents with a single copy
631N/Athat is included in the collection, provided that you follow the rules
631N/Aof this License for verbatim copying of each of the documents in all
631N/Aother respects.
631N/A
631N/AYou may extract a single document from such a collection, and
631N/Adistribute it individually under this License, provided you insert a
631N/Acopy of this License into the extracted document, and follow this
631N/ALicense in all other respects regarding verbatim copying of that
631N/Adocument.
631N/A
631N/A
631N/A7. AGGREGATION WITH INDEPENDENT WORKS
631N/A
631N/AA compilation of the Document or its derivatives with other separate
631N/Aand independent documents or works, in or on a volume of a storage or
631N/Adistribution medium, is called an "aggregate" if the copyright
631N/Aresulting from the compilation is not used to limit the legal rights
631N/Aof the compilation's users beyond what the individual works permit.
631N/AWhen the Document is included in an aggregate, this License does not
631N/Aapply to the other works in the aggregate which are not themselves
631N/Aderivative works of the Document.
631N/A
631N/AIf the Cover Text requirement of section 3 is applicable to these
631N/Acopies of the Document, then if the Document is less than one half of
631N/Athe entire aggregate, the Document's Cover Texts may be placed on
631N/Acovers that bracket the Document within the aggregate, or the
631N/Aelectronic equivalent of covers if the Document is in electronic form.
631N/AOtherwise they must appear on printed covers that bracket the whole
631N/Aaggregate.
631N/A
631N/A
631N/A8. TRANSLATION
631N/A
631N/ATranslation is considered a kind of modification, so you may
631N/Adistribute translations of the Document under the terms of section 4.
631N/AReplacing Invariant Sections with translations requires special
631N/Apermission from their copyright holders, but you may include
631N/Atranslations of some or all Invariant Sections in addition to the
2737N/Aoriginal versions of these Invariant Sections. You may include a
631N/Atranslation of this License, and all the license notices in the
631N/ADocument, and any Warranty Disclaimers, provided that you also include
631N/Athe original English version of this License and the original versions
2737N/Aof those notices and disclaimers. In case of a disagreement between
631N/Athe translation and the original version of this License or a notice
631N/Aor disclaimer, the original version will prevail.
631N/A
631N/AIf a section in the Document is Entitled "Acknowledgements",
631N/A"Dedications", or "History", the requirement (section 4) to Preserve
631N/Aits Title (section 1) will typically require changing the actual
631N/Atitle.
631N/A
631N/A
631N/A9. TERMINATION
631N/A
631N/AYou may not copy, modify, sublicense, or distribute the Document
2737N/Aexcept as expressly provided under this License. Any attempt
631N/Aotherwise to copy, modify, sublicense, or distribute it is void, and
631N/Awill automatically terminate your rights under this License.
631N/A
631N/AHowever, if you cease all violation of this License, then your license
631N/Afrom a particular copyright holder is reinstated (a) provisionally,
631N/Aunless and until the copyright holder explicitly and finally
631N/Aterminates your license, and (b) permanently, if the copyright holder
631N/Afails to notify you of the violation by some reasonable means prior to
631N/A60 days after the cessation.
631N/A
631N/AMoreover, your license from a particular copyright holder is
631N/Areinstated permanently if the copyright holder notifies you of the
631N/Aviolation by some reasonable means, this is the first time you have
631N/Areceived notice of violation of this License (for any work) from that
631N/Acopyright holder, and you cure the violation prior to 30 days after
631N/Ayour receipt of the notice.
631N/A
631N/ATermination of your rights under this section does not terminate the
631N/Alicenses of parties who have received copies or rights from you under
2737N/Athis License. If your rights have been terminated and not permanently
631N/Areinstated, receipt of a copy of some or all of the same material does
631N/Anot give you any rights to use it.
631N/A
631N/A
631N/A10. FUTURE REVISIONS OF THIS LICENSE
631N/A
631N/AThe Free Software Foundation may publish new, revised versions of the
2737N/AGNU Free Documentation License from time to time. Such new versions
631N/Awill be similar in spirit to the present version, but may differ in
2737N/Adetail to address new problems or concerns. See
631N/Ahttp://www.gnu.org/copyleft/.
631N/A
631N/AEach version of the License is given a distinguishing version number.
631N/AIf the Document specifies that a particular numbered version of this
631N/ALicense "or any later version" applies to it, you have the option of
631N/Afollowing the terms and conditions either of that specified version or
631N/Aof any later version that has been published (not as a draft) by the
2737N/AFree Software Foundation. If the Document does not specify a version
631N/Anumber of this License, you may choose any version ever published (not
2737N/Aas a draft) by the Free Software Foundation. If the Document
631N/Aspecifies that a proxy can decide which future versions of this
631N/ALicense can be used, that proxy's public statement of acceptance of a
631N/Aversion permanently authorizes you to choose that version for the
631N/ADocument.
631N/A
631N/A11. RELICENSING
631N/A
631N/A"Massive Multiauthor Collaboration Site" (or "MMC Site") means any
631N/AWorld Wide Web server that publishes copyrightable works and also
2737N/Aprovides prominent facilities for anybody to edit those works. A
2737N/Apublic wiki that anybody can edit is an example of such a server. A
631N/A"Massive Multiauthor Collaboration" (or "MMC") contained in the site
631N/Ameans any set of copyrightable works thus published on the MMC site.
631N/A
2737N/A"CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
2737N/Alicense published by Creative Commons Corporation, a not-for-profit
2737N/Acorporation with a principal place of business in San Francisco,
2737N/ACalifornia, as well as future copyleft versions of that license
631N/Apublished by that same organization.
631N/A
2737N/A"Incorporate" means to publish or republish a Document, in whole or in
631N/Apart, as part of another Document.
631N/A
2737N/AAn MMC is "eligible for relicensing" if it is licensed under this
2737N/ALicense, and if all works that were first published under this License
2737N/Asomewhere other than this MMC, and subsequently incorporated in whole or
2737N/Ain part into the MMC, (1) had no cover texts or invariant sections, and
631N/A(2) were thus incorporated prior to November 1, 2008.
631N/A
631N/AThe operator of an MMC Site may republish an MMC contained in the site
631N/Aunder CC-BY-SA on the same site at any time before August 1, 2009,
631N/Aprovided the MMC is eligible for relicensing.
631N/A
631N/A
631N/AADDENDUM: How to use this License for your documents
631N/A
631N/ATo use this License in a document you have written, include a copy of
631N/Athe License in the document and put the following copyright and
631N/Alicense notices just after the title page:
631N/A
2737N/ACopyright (c) YEAR YOUR NAME.
2737N/APermission is granted to copy, distribute and/or modify this document
2737N/Aunder the terms of the GNU Free Documentation License, Version 1.3
2737N/Aor any later version published by the Free Software Foundation;
2737N/Awith no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
2737N/AA copy of the license is included in the section entitled "GNU
2737N/AFree Documentation License".
631N/A
631N/AIf you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
631N/Areplace the "with...Texts." line with this:
631N/A
2737N/Awith the Invariant Sections being LIST THEIR TITLES, with the
2737N/AFront-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
631N/A
631N/AIf you have Invariant Sections without Cover Texts, or some other
631N/Acombination of the three, merge those two alternatives to suit the
631N/Asituation.
631N/A
631N/AIf your document contains nontrivial examples of program code, we
631N/Arecommend releasing these examples in parallel under your choice of
631N/Afree software license, such as the GNU General Public License,
631N/Ato permit their use in free software.
2737N/A
