6 Everyone is permitted to copy and distribute verbatim copies |
6 The GNU General Public License is a free, copyleft license for software and other kinds of works. |
7 of this license document, but changing it is not allowed. |
7 The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. |
8 |
8 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. |
9 Preamble |
9 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. |
10 |
10 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. |
11 The licenses for most software are designed to take away your |
11 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. |
12 freedom to share and change it. By contrast, the GNU General Public |
12 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. |
13 License is intended to guarantee your freedom to share and change free |
13 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. |

14 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. |

19 “Copyright” also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. |
20 |
20 “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. |
21 When we speak of free software, we are referring to freedom, not |
21 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. |

23 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. |

24 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. |

25 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. |
26 in new free programs; and that you know you can do these things. |
26 1. Source Code. |
27 |
27 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. |
28 To protect your rights, we need to make restrictions that forbid |
28 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. |
29 anyone to deny you these rights or to ask you to surrender the rights. |
29 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. |
30 These restrictions translate to certain responsibilities for you if you |
30 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. |
31 distribute copies of the software, or if you modify it. |
31 The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. |

34 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.

This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. |

35 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. |

37 rights. |
37 3. Protecting Users' Legal Rights From Anti-Circumvention Law. |
38 |
38 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. |
39 We protect your rights with two steps: (1) copyright the software, and |
39 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. |
40 (2) offer you this license which gives you legal permission to copy, |
40 4. Conveying Verbatim Copies. |
41 distribute and/or modify the software. |
41 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. |
42 |
42 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. |
43 Also, for each author's protection and ours, we want to make certain |
43 5. Conveying Modified Source Versions. |
44 that everyone understands that there is no warranty for this free |
44 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: |

45 a) The work must carry prominent notices stating that you modified it, and giving a relevant date. |
46 want its recipients to know that what they have is not the original, so |
46 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”. |
47 that any problems introduced by others will not reflect on the original |
47 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. |
48 authors' reputations. |
48 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. |
49 |
49 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. |
50 Finally, any free program is threatened constantly by software |

51 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: |

53 program proprietary. To prevent this, we have made it clear that any |
53 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. |
54 patent must be licensed for everyone's free use or not licensed at all. |
54 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. |
55 |
55 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. |
56 The precise terms and conditions for copying, distribution and |
56 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. |
57 modification follow. |
57 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. |
58 ^L |
58 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. |
59 GNU GENERAL PUBLIC LICENSE |
59 “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. |
60 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
60 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). |
61 |
61 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. |
62 0. This License applies to any program or other work which contains |
62 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. |
63 a notice placed by the copyright holder saying it may be distributed |
63 7. Additional Terms. |
64 under the terms of this General Public License. The "Program", below, |
64 “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. |
65 refers to any such program or work, and a "work based on the Program" |
65 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. |
66 means either the Program or any derivative work under copyright law: |
66 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: |
67 that is to say, a work containing the Program or a portion of it, |
67 a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or |
68 either verbatim or with modifications and/or translated into another |
68 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 |
69 language. (Hereinafter, translation is included without limitation in |
69 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 |
70 the term "modification".) Each licensee is addressed as "you". |
70 d) Limiting the use for publicity purposes of names of licensors or authors of the material; or |
71 |
71 e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or |
72 Activities other than copying, distribution and modification are not |
72 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. |

73 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. |
74 running the Program is not restricted, and the output from the Program |

76 Program (independent of having been made by running the Program). |
76 8. Termination. |
77 Whether that is true depends on what the Program does. |
77 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). |
78 |
78 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. |
79 1. You may copy and distribute verbatim copies of the Program's |
79 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. |

80 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. |

82 copyright notice and disclaimer of warranty; keep intact all the |
82 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. |
83 notices that refer to this License and to the absence of any warranty; |
83 10. Automatic Licensing of Downstream Recipients. |
84 and give any other recipients of the Program a copy of this License |
84 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. |
85 along with the Program. |
85 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. |
86 |
86 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. |
87 You may charge a fee for the physical act of transferring a copy, and |
87 11. Patents. |
88 you may at your option offer warranty protection in exchange for a fee. |
88 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”. |
89 |
89 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. |
90 2. You may modify your copy or copies of the Program or any portion |
90 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. |
91 of it, thus forming a work based on the Program, and copy and |
91 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. |
92 distribute such modifications or work under the terms of Section 1 |
92 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. |
93 above, provided that you also meet all of these conditions: |
93 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. |
94 |
94 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. |
95 a) You must cause the modified files to carry prominent notices |
95 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. |
96 stating that you changed the files and the date of any change. |
96 12. No Surrender of Others' Freedom. |
97 |
97 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. |
98 b) You must cause any work that you distribute or publish, that in |

99 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. |

101 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. |
102 |
102 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. |
103 c) If the modified program normally reads commands interactively |

112 How to Apply These Terms to Your New Programs |
113 ^L |
113 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. |
114 These requirements apply to the modified work as a whole. If |
114 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. |
115 identifiable sections of that work are not derived from the Program, |

145 The purpose of this License is to make a manual, textbook, or other functional and useful document "free" in the sense of freedom: to assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either commercially or noncommercially. Secondarily, this License preserves for the author and publisher a way to get credit for their work, while not being considered responsible for modifications made by others. |

146 This License is a kind of "copyleft", which means that derivative works of the document must themselves be free in the same sense. It complements the GNU General Public License, which is a copyleft license designed for free software. |
147 customarily used for software interchange; or, |
147 We have designed this License in order to use it for manuals for free software, because free software needs free documentation: a free program should come with manuals providing the same freedoms that the software does. But this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether it is published as a printed book. We recommend this License principally for works whose purpose is instruction or reference. |
148 |
148 1. APPLICABILITY AND DEFINITIONS |
149 c) Accompany it with the information you received as to the offer |
149 This License applies to any manual or other work, in any medium, that contains a notice placed by the copyright holder saying it can be distributed under the terms of this License. Such a notice grants a world-wide, royalty-free license, unlimited in duration, to use that work under the conditions stated herein. The "Document", below, refers to any such manual or work. Any member of the public is a licensee, and is addressed as "you". You accept the license if you copy, modify or distribute the work in a way requiring permission under copyright law. |
150 to distribute corresponding source code. (This alternative is |
150 A "Modified Version" of the Document means any work containing the Document or a portion of it, either copied verbatim, or with modifications and/or translated into another language. |
151 allowed only for noncommercial distribution and only if you |
151 A "Secondary Section" is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document's overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (Thus, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them. |
152 received the program in object code or executable form with such |
152 The "Invariant Sections" are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections. If the Document does not identify any Invariant Sections then there are none. |
153 an offer, in accord with Subsection b above.) |
153 The "Cover Texts" are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at most 25 words. |
154 |
154 A "Transparent" copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not "Transparent" is called "Opaque". |
155 The source code for a work means the preferred form of the work for |
155 Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML, PostScript or PDF designed for human modification. Examples of transparent image formats include PNG, XCF and JPG. Opaque formats include proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML, PostScript or PDF produced by some word processors for output purposes only. |
156 making modifications to it. For an executable work, complete source |
156 The "Title Page" means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, "Title Page" means the text near the most prominent appearance of the work's title, preceding the beginning of the body of the text. |
157 code means all the source code for all modules it contains, plus any |
157 The "publisher" means any person or entity that distributes copies of the Document to the public. |
158 associated interface definition files, plus the scripts used to |
158 A section "Entitled XYZ" means a named subunit of the Document whose title either is precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another language. (Here XYZ stands for a specific section name mentioned below, such as "Acknowledgements", "Dedications", "Endorsements", or "History".) To "Preserve the Title" of such a section when you modify the Document means that it remains a section "Entitled XYZ" according to this definition. |

159 The Document may include Warranty Disclaimers next to the notice which states that this License applies to the Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on the meaning of this License. |

161 You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3. |

164 itself accompanies the executable. |
164 If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document's license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects. |
165 |
165 If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages. |
166 If distribution of executable or object code is made by offering |
166 If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public. |

168 4. MODIFICATIONS |
169 distribution of the source code, even though third parties are not |
169 You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version: |
170 compelled to copy the source along with the object code. |
170 A. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of previous versions (which should, if there were any, be listed in the History section of the Document). You may use the same title as a previous version if the original publisher of that version gives permission. |
171 ^L |
171 B. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications in the Modified Version, together with at least five of the principal authors of the Document (all of its principal authors, if it has fewer than five), unless they release you from this requirement. |
172 4. You may not copy, modify, sublicense, or distribute the Program |

175 F. Include, immediately after the copyright notices, a license notice giving the public permission to use the Modified Version under the terms of this License, in the form shown in the Addendum below. |
176 However, parties who have received copies, or rights, from you under |
176 G. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document's license notice. |
177 this License will not have their licenses terminated so long as such |
177 H. Include an unaltered copy of this License. |
178 parties remain in full compliance. |
178 I. Preserve the section Entitled "History", Preserve its Title, and add to it an item stating at least the title, year, new authors, and publisher of the Modified Version as given on the Title Page. If there is no section Entitled "History" in the Document, create one stating the title, year, authors, and publisher of the Document as given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence. |
179 |
179 J. Preserve the network location, if any, given in the Document for public access to a Transparent copy of the Document, and likewise the network locations given in the Document for previous versions it was based on. These may be placed in the "History" section. You may omit a network location for a work that was published at least four years before the Document itself, or if the original publisher of the version it refers to gives permission. |
180 5. You are not required to accept this License, since you have not |

185 If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material copied from the Document, you may at your option designate some or all of these sections as invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version's license notice. These titles must be distinct from any other section titles. |
186 all its terms and conditions for copying, distributing or modifying |
186 You may add a section Entitled "Endorsements", provided it contains nothing but endorsements of your Modified Version by various parties—for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard. |
187 the Program or works based on it. |
187 You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one. |
188 |
188 The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version. |

190 Program), the recipient automatically receives a license from the |
190 You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and that you preserve all their Warranty Disclaimers. |

191 The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work. |

197 A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, is called an "aggregate" if the copyright resulting from the compilation is not used to limit the legal rights of the compilation's users beyond what the individual works permit. When the Document is included in an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document. |

198 If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one half of the entire aggregate, the Document's Cover Texts may be placed on covers that bracket the Document within the aggregate, or the electronic equivalent of covers if the Document is in electronic form. Otherwise they must appear on printed covers that bracket the whole aggregate. |

200 Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License, and all the license notices in the Document, and any Warranty Disclaimers, provided that you also include the original English version of this License and the original versions of those notices and disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail. |

208 refrain entirely from distribution of the Program. |
208 The Free Software Foundation may publish new, revised versions of the GNU Free Documentation 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. See http://www.gnu.org/copyleft/. |

209 Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License "or any later version" applies to it, you have the option of following the terms and conditions either of that specified version or of any later version that has been published (not as a draft) by the Free Software Foundation. If the Document does not specify a version number of this License, you may choose any version ever published (not as a draft) by the Free Software Foundation. If the Document specifies that a proxy can decide which future versions of this License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Document. |

219 implemented by public license practices. Many people have made |
219 Permission is granted to copy, distribute and/or modify this document |
220 generous contributions to the wide range of software distributed |
220 under the terms of the GNU Free Documentation License, Version 1.3 |
221 through that system in reliance on consistent application of that |
221 or any later version published by the Free Software Foundation; |
222 system; it is up to the author/donor to decide if he or she is willing |

223 to distribute software through any other system and a licensee cannot |
223 A copy of the license is included in the section entitled "GNU |

224 Free Documentation License". |
225 |
225 If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, replace the "with … Texts." line with this: |
226 This section is intended to make thoroughly clear what is believed to |
226 with the Invariant Sections being LIST THEIR TITLES, with the |
227 be a consequence of the rest of this License. |
227 Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. |
228 ^L |
228 If you have Invariant Sections without Cover Texts, or some other combination of the three, merge those two alternatives to suit the situation. |
229 8. If the distribution and/or use of the Program is restricted in |
229 If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the GNU General Public License, to permit their use in free software. |
230 certain countries either by patents or by copyrighted interfaces, the |
|
231 original copyright holder who places the Program under this License |
|
232 may add an explicit geographical distribution limitation excluding |
|
233 those countries, so that distribution is permitted only in or among |
|
234 countries not thus excluded. In such case, this License incorporates |
|
235 the limitation as if written in the body of this License. |
|
236 |
|
237 9. The Free Software Foundation may publish revised and/or new versions |
|
238 of the General Public License from time to time. Such new versions will |
|
239 be similar in spirit to the present version, but may differ in detail to |
|
240 address new problems or concerns. |
|
241 |
|
242 Each version is given a distinguishing version number. If the Program |
|
243 specifies a version number of this License which applies to it and "any |
|
244 later version", you have the option of following the terms and conditions |
|
245 either of that version or of any later version published by the Free |
|
246 Software Foundation. If the Program does not specify a version number of |
|
247 this License, you may choose any version ever published by the Free Software |
|
248 Foundation. |
|
249 |
|
250 10. If you wish to incorporate parts of the Program into other free |
|
251 programs whose distribution conditions are different, write to the author |
|
252 to ask for permission. For software which is copyrighted by the Free |
|
253 Software Foundation, write to the Free Software Foundation; we sometimes |
|
254 make exceptions for this. Our decision will be guided by the two goals |
|
255 of preserving the free status of all derivatives of our free software and |
|
256 of promoting the sharing and reuse of software generally. |
|
257 |
|
258 NO WARRANTY |
|
259 |
|
260 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY |
|
261 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN |
|
262 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES |
|
263 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED |
|
264 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF |
|
265 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS |
|
266 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE |
|
267 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, |
|
268 REPAIR OR CORRECTION. |
|
269 |
|
270 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING |
|
271 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR |
|
272 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, |
|
273 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING |
|
274 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED |
|
275 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY |
|
276 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER |
|
277 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE |
|
278 POSSIBILITY OF SUCH DAMAGES. |
|
279 |
|
280 END OF TERMS AND CONDITIONS |
|
281 ^L |
|
282 How to Apply These Terms to Your New Programs |
|
283 |
|
284 If you develop a new program, and you want it to be of the greatest |
|
285 possible use to the public, the best way to achieve this is to make it |
|
286 free software which everyone can redistribute and change under these terms. |
|
287 |
|
288 To do so, attach the following notices to the program. It is safest |
|
289 to attach them to the start of each source file to most effectively |
|
290 convey the exclusion of warranty; and each file should have at least |
|
291 the "copyright" line and a pointer to where the full notice is found. |
|
292 |
|
293 <one line to give the program's name and a brief idea of what it does.> |
|
294 Copyright (C) <year> <name of author> |
|
295 |
|
296 This program is free software; you can redistribute it and/or modify |
|
297 it under the terms of the GNU General Public License as published by |
|
298 the Free Software Foundation; either version 2 of the License, or |
|
299 (at your option) any later version. |
|
300 |
|
301 This program is distributed in the hope that it will be useful, |
|
302 but WITHOUT ANY WARRANTY; without even the implied warranty of |
|
303 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the |
|
304 GNU General Public License for more details. |
|
305 |
|
306 You should have received a copy of the GNU General Public License |
|
307 along with this program; if not, write to the Free Software |
|
308 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA |
|
309 |
|
310 |
|
311 Also add information on how to contact you by electronic and paper mail. |
|
312 |
|
313 If the program is interactive, make it output a short notice like this |
|
314 when it starts in an interactive mode: |
|
315 |
|
316 Gnomovision version 69, Copyright (C) year name of author |
|
317 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. |
|
318 This is free software, and you are welcome to redistribute it |
|
319 under certain conditions; type `show c' for details. |
|
320 |
|
321 The hypothetical commands `show w' and `show c' should show the appropriate |
|
322 parts of the General Public License. Of course, the commands you use may |
|
323 be called something other than `show w' and `show c'; they could even be |
|
324 mouse-clicks or menu items--whatever suits your program. |
|
325 |
|
326 You should also get your employer (if you work as a programmer) or your |
|
327 school, if any, to sign a "copyright disclaimer" for the program, if |
|
328 necessary. Here is a sample; alter the names: |
|
329 |
|
330 Yoyodyne, Inc., hereby disclaims all copyright interest in the program |
|
331 `Gnomovision' (which makes passes at compilers) written by James Hacker. |

|
336 This General Public License does not permit incorporating your program into |
|
337 proprietary programs. If your program is a subroutine library, you may |
|
338 consider it more useful to permit linking proprietary applications with the |
|
339 library. If this is what you want to do, use the GNU Library General |
|
340 Public License instead of this License. |

|
350 Everyone is permitted to copy and distribute verbatim copies |
|
351 of this license document, but changing it is not allowed. |
|
352 |
|
353 0. PREAMBLE |
|
354 |
|
355 The purpose of this License is to make a manual, textbook, or other |
|
356 functional and useful document "free" in the sense of freedom: to |
|
357 assure everyone the effective freedom to copy and redistribute it, |
|
358 with or without modifying it, either commercially or |
|
359 noncommercially. Secondarily, this License preserves for the |
|
360 author and publisher a way to get credit for their work, while not |
|
361 being considered responsible for modifications made by others. |
|
362 |
|
363 This License is a kind of "copyleft", which means that derivative |
|
364 works of the document must themselves be free in the same sense. |
|
365 It complements the GNU General Public License, which is a copyleft |
|
366 license designed for free software. |
|
367 |
|
368 We have designed this License in order to use it for manuals for |
|
369 free software, because free software needs free documentation: a |
|
370 free program should come with manuals providing the same freedoms |
|
371 that the software does. But this License is not limited to |
|
372 software manuals; it can be used for any textual work, regardless |
|
373 of subject matter or whether it is published as a printed book. |
|
374 We recommend this License principally for works whose purpose is |
|
375 instruction or reference. |
|
376 |
|
377 1. APPLICABILITY AND DEFINITIONS |
|
378 |
|
379 This License applies to any manual or other work, in any medium, |
|
380 that contains a notice placed by the copyright holder saying it |
|
381 can be distributed under the terms of this License. Such a notice |
|
382 grants a world-wide, royalty-free license, unlimited in duration, |
|
383 to use that work under the conditions stated herein. The |
|
384 "Document", below, refers to any such manual or work. Any member |
|
385 of the public is a licensee, and is addressed as "you". You |
|
386 accept the license if you copy, modify or distribute the work in a |
|
387 way requiring permission under copyright law. |
|
388 |
|
389 A "Modified Version" of the Document means any work containing the |
|
390 Document or a portion of it, either copied verbatim, or with |
|
391 modifications and/or translated into another language. |
|
392 |
|
393 A "Secondary Section" is a named appendix or a front-matter section |
|
394 of the Document that deals exclusively with the relationship of the |
|
395 publishers or authors of the Document to the Document's overall |
|
396 subject (or to related matters) and contains nothing that could |
|
397 fall directly within that overall subject. (Thus, if the Document |
|
398 is in part a textbook of mathematics, a Secondary Section may not |
|
399 explain any mathematics.) The relationship could be a matter of |
|
400 historical connection with the subject or with related matters, or |
|
401 of legal, commercial, philosophical, ethical or political position |
|
402 regarding them. |
|
403 |
|
404 The "Invariant Sections" are certain Secondary Sections whose |
|
405 titles are designated, as being those of Invariant Sections, in |
|
406 the notice that says that the Document is released under this |
|
407 License. If a section does not fit the above definition of |
|
408 Secondary then it is not allowed to be designated as Invariant. |
|
409 The Document may contain zero Invariant Sections. If the Document |
|
410 does not identify any Invariant Sections then there are none. |
|
411 |
|
412 The "Cover Texts" are certain short passages of text that are |
|
413 listed, as Front-Cover Texts or Back-Cover Texts, in the notice |
|
414 that says that the Document is released under this License. A |
|
415 Front-Cover Text may be at most 5 words, and a Back-Cover Text may |
|
416 be at most 25 words. |
|
417 |
|
418 A "Transparent" copy of the Document means a machine-readable copy, |
|
419 represented in a format whose specification is available to the |
|
420 general public, that is suitable for revising the document |
|
421 straightforwardly with generic text editors or (for images |
|
422 composed of pixels) generic paint programs or (for drawings) some |
|
423 widely available drawing editor, and that is suitable for input to |
|
424 text formatters or for automatic translation to a variety of |
|
425 formats suitable for input to text formatters. A copy made in an |
|
426 otherwise Transparent file format whose markup, or absence of |
|
427 markup, has been arranged to thwart or discourage subsequent |
|
428 modification by readers is not Transparent. An image format is |
|
429 not Transparent if used for any substantial amount of text. A |
|
430 copy that is not "Transparent" is called "Opaque". |
|
431 |
|
432 Examples of suitable formats for Transparent copies include plain |
|
433 ASCII without markup, Texinfo input format, LaTeX input format, |
|
434 SGML or XML using a publicly available DTD, and |
|
435 standard-conforming simple HTML, PostScript or PDF designed for |
|
436 human modification. Examples of transparent image formats include |
|
437 PNG, XCF and JPG. Opaque formats include proprietary formats that |
|
438 can be read and edited only by proprietary word processors, SGML or |
|
439 XML for which the DTD and/or processing tools are not generally |
|
440 available, and the machine-generated HTML, PostScript or PDF |
|
441 produced by some word processors for output purposes only. |
|
442 |
|
443 The "Title Page" means, for a printed book, the title page itself, |
|
444 plus such following pages as are needed to hold, legibly, the |
|
445 material this License requires to appear in the title page. For |
|
446 works in formats which do not have any title page as such, "Title |
|
447 Page" means the text near the most prominent appearance of the |
|
448 work's title, preceding the beginning of the body of the text. |
|
449 |
|
450 A section "Entitled XYZ" means a named subunit of the Document |
|
451 whose title either is precisely XYZ or contains XYZ in parentheses |
|
452 following text that translates XYZ in another language. (Here XYZ |
|
453 stands for a specific section name mentioned below, such as |
|
454 "Acknowledgements", "Dedications", "Endorsements", or "History".) |
|
455 To "Preserve the Title" of such a section when you modify the |
|
456 Document means that it remains a section "Entitled XYZ" according |
|
457 to this definition. |
|
458 |
|
459 The Document may include Warranty Disclaimers next to the notice |
|
460 which states that this License applies to the Document. These |
|
461 Warranty Disclaimers are considered to be included by reference in |
|
462 this License, but only as regards disclaiming warranties: any other |
|
463 implication that these Warranty Disclaimers may have is void and |
|
464 has no effect on the meaning of this License. |
|
465 |
|
466 2. VERBATIM COPYING |
|
467 |
|
468 You may copy and distribute the Document in any medium, either |
|
469 commercially or noncommercially, provided that this License, the |
|
470 copyright notices, and the license notice saying this License |
|
471 applies to the Document are reproduced in all copies, and that you |
|
472 add no other conditions whatsoever to those of this License. You |
|
473 may not use technical measures to obstruct or control the reading |
|
474 or further copying of the copies you make or distribute. However, |
|
475 you may accept compensation in exchange for copies. If you |
|
476 distribute a large enough number of copies you must also follow |
|
477 the conditions in section 3. |
|
478 |
|
479 You may also lend copies, under the same conditions stated above, |
|
480 and you may publicly display copies. |
|
481 |
|
482 3. COPYING IN QUANTITY |
|
483 |
|
484 If you publish printed copies (or copies in media that commonly |
|
485 have printed covers) of the Document, numbering more than 100, and |
|
486 the Document's license notice requires Cover Texts, you must |
|
487 enclose the copies in covers that carry, clearly and legibly, all |
|
488 these Cover Texts: Front-Cover Texts on the front cover, and |
|
489 Back-Cover Texts on the back cover. Both covers must also clearly |
|
490 and legibly identify you as the publisher of these copies. The |
|
491 front cover must present the full title with all words of the |
|
492 title equally prominent and visible. You may add other material |
|
493 on the covers in addition. Copying with changes limited to the |
|
494 covers, as long as they preserve the title of the Document and |
|
495 satisfy these conditions, can be treated as verbatim copying in |
|
496 other respects. |
|
497 |
|
498 If the required texts for either cover are too voluminous to fit |
|
499 legibly, you should put the first ones listed (as many as fit |
|
500 reasonably) on the actual cover, and continue the rest onto |
|
501 adjacent pages. |
|
502 |
|
503 If you publish or distribute Opaque copies of the Document |
|
504 numbering more than 100, you must either include a |
|
505 machine-readable Transparent copy along with each Opaque copy, or |
|
506 state in or with each Opaque copy a computer-network location from |
|
507 which the general network-using public has access to download |
|
508 using public-standard network protocols a complete Transparent |
|
509 copy of the Document, free of added material. If you use the |
|
510 latter option, you must take reasonably prudent steps, when you |
|
511 begin distribution of Opaque copies in quantity, to ensure that |
|
512 this Transparent copy will remain thus accessible at the stated |
|
513 location until at least one year after the last time you |
|
514 distribute an Opaque copy (directly or through your agents or |
|
515 retailers) of that edition to the public. |
|
516 |
|
517 It is requested, but not required, that you contact the authors of |
|
518 the Document well before redistributing any large number of |
|
519 copies, to give them a chance to provide you with an updated |
|
520 version of the Document. |
|
521 |
|
522 4. MODIFICATIONS |
|
523 |
|
524 You may copy and distribute a Modified Version of the Document |
|
525 under the conditions of sections 2 and 3 above, provided that you |
|
526 release the Modified Version under precisely this License, with |
|
527 the Modified Version filling the role of the Document, thus |
|
528 licensing distribution and modification of the Modified Version to |
|
529 whoever possesses a copy of it. In addition, you must do these |
|
530 things in the Modified Version: |
|
531 |
|
532 A. Use in the Title Page (and on the covers, if any) a title |
|
533 distinct from that of the Document, and from those of |
|
534 previous versions (which should, if there were any, be listed |
|
535 in the History section of the Document). You may use the |
|
536 same title as a previous version if the original publisher of |
|
537 that version gives permission. |
|
538 |
|
539 B. List on the Title Page, as authors, one or more persons or |
|
540 entities responsible for authorship of the modifications in |
|
541 the Modified Version, together with at least five of the |
|
542 principal authors of the Document (all of its principal |
|
543 authors, if it has fewer than five), unless they release you |
|
544 from this requirement. |
|
545 |
|
546 C. State on the Title page the name of the publisher of the |
|
547 Modified Version, as the publisher. |
|
548 |
|
549 D. Preserve all the copyright notices of the Document. |
|
550 |
|
551 E. Add an appropriate copyright notice for your modifications |
|
552 adjacent to the other copyright notices. |
|
553 |
|
554 F. Include, immediately after the copyright notices, a license |
|
555 notice giving the public permission to use the Modified |
|
556 Version under the terms of this License, in the form shown in |
|
557 the Addendum below. |
|
558 |
|
559 G. Preserve in that license notice the full lists of Invariant |
|
560 Sections and required Cover Texts given in the Document's |
|
561 license notice. |
|
562 |
|
563 H. Include an unaltered copy of this License. |
|
564 |
|
565 I. Preserve the section Entitled "History", Preserve its Title, |
|
566 and add to it an item stating at least the title, year, new |
|
567 authors, and publisher of the Modified Version as given on |
|
568 the Title Page. If there is no section Entitled "History" in |
|
569 the Document, create one stating the title, year, authors, |
|
570 and publisher of the Document as given on its Title Page, |
|
571 then add an item describing the Modified Version as stated in |
|
572 the previous sentence. |
|
573 |
|
574 J. Preserve the network location, if any, given in the Document |
|
575 for public access to a Transparent copy of the Document, and |
|
576 likewise the network locations given in the Document for |
|
577 previous versions it was based on. These may be placed in |
|
578 the "History" section. You may omit a network location for a |
|
579 work that was published at least four years before the |
|
580 Document itself, or if the original publisher of the version |
|
581 it refers to gives permission. |
|
582 |
|
583 K. For any section Entitled "Acknowledgements" or "Dedications", |
|
584 Preserve the Title of the section, and preserve in the |
|
585 section all the substance and tone of each of the contributor |
|
586 acknowledgements and/or dedications given therein. |
|
587 |
|
588 L. Preserve all the Invariant Sections of the Document, |
|
589 unaltered in their text and in their titles. Section numbers |
|
590 or the equivalent are not considered part of the section |
|
591 titles. |
|
592 |
|
593 M. Delete any section Entitled "Endorsements". Such a section |
|
594 may not be included in the Modified Version. |
|
595 |
|
596 N. Do not retitle any existing section to be Entitled |
|
597 "Endorsements" or to conflict in title with any Invariant |
|
598 Section. |
|
599 |
|
600 O. Preserve any Warranty Disclaimers. |
|
601 |
|
602 If the Modified Version includes new front-matter sections or |
|
603 appendices that qualify as Secondary Sections and contain no |
|
604 material copied from the Document, you may at your option |
|
605 designate some or all of these sections as invariant. To do this, |
|
606 add their titles to the list of Invariant Sections in the Modified |
|
607 Version's license notice. These titles must be distinct from any |
|
608 other section titles. |
|
609 |
|
610 You may add a section Entitled "Endorsements", provided it contains |
|
611 nothing but endorsements of your Modified Version by various |
|
612 parties--for example, statements of peer review or that the text |
|
613 has been approved by an organization as the authoritative |
|
614 definition of a standard. |
|
615 |
|
616 You may add a passage of up to five words as a Front-Cover Text, |
|
617 and a passage of up to 25 words as a Back-Cover Text, to the end |
|
618 of the list of Cover Texts in the Modified Version. Only one |
|
619 passage of Front-Cover Text and one of Back-Cover Text may be |
|
620 added by (or through arrangements made by) any one entity. If the |
|
621 Document already includes a cover text for the same cover, |
|
622 previously added by you or by arrangement made by the same entity |
|
623 you are acting on behalf of, you may not add another; but you may |
|
624 replace the old one, on explicit permission from the previous |
|
625 publisher that added the old one. |
|
626 |
|
627 The author(s) and publisher(s) of the Document do not by this |
|
628 License give permission to use their names for publicity for or to |
|
629 assert or imply endorsement of any Modified Version. |
|
630 |
|
631 5. COMBINING DOCUMENTS |
|
632 |
|
633 You may combine the Document with other documents released under |
|
634 this License, under the terms defined in section 4 above for |
|
635 modified versions, provided that you include in the combination |
|
636 all of the Invariant Sections of all of the original documents, |
|
637 unmodified, and list them all as Invariant Sections of your |
|
638 combined work in its license notice, and that you preserve all |
|
639 their Warranty Disclaimers. |
|
640 |
|
641 The combined work need only contain one copy of this License, and |
|
642 multiple identical Invariant Sections may be replaced with a single |
|
643 copy. If there are multiple Invariant Sections with the same name |
|
644 but different contents, make the title of each such section unique |
|
645 by adding at the end of it, in parentheses, the name of the |
|
646 original author or publisher of that section if known, or else a |
|
647 unique number. Make the same adjustment to the section titles in |
|
648 the list of Invariant Sections in the license notice of the |
|
649 combined work. |
|
650 |
|
651 In the combination, you must combine any sections Entitled |
|
652 "History" in the various original documents, forming one section |
|
653 Entitled "History"; likewise combine any sections Entitled |
|
654 "Acknowledgements", and any sections Entitled "Dedications". You |
|
655 must delete all sections Entitled "Endorsements." |
|
656 |
|
657 6. COLLECTIONS OF DOCUMENTS |
|
658 |
|
659 You may make a collection consisting of the Document and other |
|
660 documents released under this License, and replace the individual |
|
661 copies of this License in the various documents with a single copy |
|
662 that is included in the collection, provided that you follow the |
|
663 rules of this License for verbatim copying of each of the |
|
664 documents in all other respects. |
|
665 |
|
666 You may extract a single document from such a collection, and |
|
667 distribute it individually under this License, provided you insert |
|
668 a copy of this License into the extracted document, and follow |
|
669 this License in all other respects regarding verbatim copying of |
|
670 that document. |
|
671 |
|
672 7. AGGREGATION WITH INDEPENDENT WORKS |
|
673 |
|
674 A compilation of the Document or its derivatives with other |
|
675 separate and independent documents or works, in or on a volume of |
|
676 a storage or distribution medium, is called an "aggregate" if the |
|
677 copyright resulting from the compilation is not used to limit the |
|
678 legal rights of the compilation's users beyond what the individual |
|
679 works permit. When the Document is included in an aggregate, this |
|
680 License does not apply to the other works in the aggregate which |
|
681 are not themselves derivative works of the Document. |
|
682 |
|
683 If the Cover Text requirement of section 3 is applicable to these |
|
684 copies of the Document, then if the Document is less than one half |
|
685 of the entire aggregate, the Document's Cover Texts may be placed |
|
686 on covers that bracket the Document within the aggregate, or the |
|
687 electronic equivalent of covers if the Document is in electronic |
|
688 form. Otherwise they must appear on printed covers that bracket |
|
689 the whole aggregate. |
|
690 |
|
691 8. TRANSLATION |
|
692 |
|
693 Translation is considered a kind of modification, so you may |
|
694 distribute translations of the Document under the terms of section |
|
695 4. Replacing Invariant Sections with translations requires special |
|
696 permission from their copyright holders, but you may include |
|
697 translations of some or all Invariant Sections in addition to the |
|
698 original versions of these Invariant Sections. You may include a |
|
699 translation of this License, and all the license notices in the |
|
700 Document, and any Warranty Disclaimers, provided that you also |
|
701 include the original English version of this License and the |
|
702 original versions of those notices and disclaimers. In case of a |
|
703 disagreement between the translation and the original version of |
|
704 this License or a notice or disclaimer, the original version will |
|
705 prevail. |
|
706 |
|
707 If a section in the Document is Entitled "Acknowledgements", |
|
708 "Dedications", or "History", the requirement (section 4) to |
|
709 Preserve its Title (section 1) will typically require changing the |
|
710 actual title. |
|
711 |
|
712 9. TERMINATION |
|
713 |
|
714 You may not copy, modify, sublicense, or distribute the Document |
|
715 except as expressly provided for under this License. Any other |
|
716 attempt to copy, modify, sublicense or distribute the Document is |
|
717 void, and will automatically terminate your rights under this |
|
718 License. However, parties who have received copies, or rights, |
|
719 from you under this License will not have their licenses |
|
720 terminated so long as such parties remain in full compliance. |
|
721 |
|
722 10. FUTURE REVISIONS OF THIS LICENSE |
|
723 |
|
724 The Free Software Foundation may publish new, revised versions of |
|
725 the GNU Free Documentation License from time to time. Such new |
|
726 versions will be similar in spirit to the present version, but may |
|
727 differ in detail to address new problems or concerns. See |
|
728 `http://www.gnu.org/copyleft/'. |
|
729 |
|
730 Each version of the License is given a distinguishing version |
|
731 number. If the Document specifies that a particular numbered |
|
732 version of this License "or any later version" applies to it, you |
|
733 have the option of following the terms and conditions either of |
|
734 that specified version or of any later version that has been |
|
735 published (not as a draft) by the Free Software Foundation. If |
|
736 the Document does not specify a version number of this License, |
|
737 you may choose any version ever published (not as a draft) by the |
|
738 Free Software Foundation. |
|
739 |
|
740 0.1.1 ADDENDUM: How to use this License for your documents |
|
741 ---------------------------------------------------------- |
|
742 |
|
743 To use this License in a document you have written, include a copy of |
|
744 the License in the document and put the following copyright and license |
|
745 notices just after the title page: |
|
746 |
|
747 Copyright (C) YEAR YOUR NAME. |
|
748 Permission is granted to copy, distribute and/or modify this document |
|
749 under the terms of the GNU Free Documentation License, Version 1.2 |
|
750 or any later version published by the Free Software Foundation; |
|
751 with no Invariant Sections, no Front-Cover Texts, and no Back-Cover |
|
752 Texts. A copy of the license is included in the section entitled ``GNU |
|
753 Free Documentation License''. |
|
754 |
|
755 If you have Invariant Sections, Front-Cover Texts and Back-Cover |
|
756 Texts, replace the "with...Texts." line with this: |
|
757 |
|
758 with the Invariant Sections being LIST THEIR TITLES, with |
|
759 the Front-Cover Texts being LIST, and with the Back-Cover Texts |
|
760 being LIST. |
|
761 |
|
762 If you have Invariant Sections without Cover Texts, or some other |
|
763 combination of the three, merge those two alternatives to suit the |
|
764 situation. |
|
765 |
|
766 If your document contains nontrivial examples of program code, we |
|
767 recommend releasing these examples in parallel under your choice of |
|
768 free software license, such as the GNU General Public License, to |
|
769 permit their use in free software. |
