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. + + 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. + + 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. + +2. **APPLICABILITY AND DEFINITIONS** + + 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. + + 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. + + 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. + + 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. + + 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. + + 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”. + + 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. + + 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. + + The “publisher” means any person or entity that distributes copies + of the Document to the public. + + 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. + + 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. + +3. **VERBATIM COPYING** + + 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. + + You may also lend copies, under the same conditions stated above, + and you may publicly display copies. + +4. **COPYING IN QUANTITY** + + 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. + + 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. + + 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. + + It is requested, but not required, that you contact the authors of + the Document well before redistributing any large number of copies, + to give them a chance to provide you with an updated version of + the Document. + +5. **MODIFICATIONS** + + 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: + + 1. 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. + 2. 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. + 3. State on the Title page the name of the publisher of the + Modified Version, as the publisher. + 4. Preserve all the copyright notices of the Document. + 5. Add an appropriate copyright notice for your modifications + adjacent to the other copyright notices. + 6. 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. + 7. Preserve in that license notice the full lists of Invariant + Sections and required Cover Texts given in the Document’s + license notice. + 8. Include an unaltered copy of this License. + 9. 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. + 10. 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. + 11. For any section Entitled “Acknowledgements” or “Dedications”, + Preserve the Title of the section, and preserve in the section + all the substance and tone of each of the contributor + acknowledgements and/or dedications given therein. + 12. Preserve all the Invariant Sections of the Document, unaltered + in their text and in their titles. Section numbers or the + equivalent are not considered part of the section titles. + 13. Delete any section Entitled “Endorsements”. Such a section may + not be included in the Modified Version. + 14. Do not retitle any existing section to be Entitled + “Endorsements” or to conflict in title with any + Invariant Section. + 15. Preserve any Warranty Disclaimers. + + 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. + + 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. + + 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. + + 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. + +6. **COMBINING DOCUMENTS** + + 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. + + 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. + + In the combination, you must combine any sections Entitled “History” + in the various original documents, forming one section Entitled + “History”; likewise combine any sections Entitled + “Acknowledgements”, and any sections Entitled “Dedications”. You + must delete all sections Entitled “Endorsements.” + +7. **COLLECTIONS OF DOCUMENTS** + + You may make a collection consisting of the Document and other + documents released under this License, and replace the individual + copies of this License in the various documents with a single copy + that is included in the collection, provided that you follow the + rules of this License for verbatim copying of each of the documents + in all other respects. + + You may extract a single document from such a collection, and + distribute it individually under this License, provided you insert a + copy of this License into the extracted document, and follow this + License in all other respects regarding verbatim copying of + that document. + +8. **AGGREGATION WITH INDEPENDENT WORKS** + + 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. + + 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. + +9. **TRANSLATION** + + 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. + + If a section in the Document is Entitled “Acknowledgements”, + “Dedications”, or “History”, the requirement (section 4) to Preserve + its Title (section 1) will typically require changing the + actual title. + +10. **TERMINATION** + + You may not copy, modify, sublicense, or distribute the Document + except as expressly provided under this License. Any attempt + otherwise to copy, modify, sublicense, or distribute it is void, and + will automatically terminate your rights under this License. + + However, if you cease all violation of this License, then your + license from a particular copyright holder is reinstated (a) + provisionally, unless and until the copyright holder explicitly and + finally terminates your license, and (b) permanently, if the + copyright holder fails to notify you of the violation by some + reasonable means prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is + reinstated permanently if the copyright holder notifies you of the + violation by some reasonable means, this is the first time you have + received notice of violation of this License (for any work) from + that copyright holder, and you cure the violation prior to 30 days + after your receipt of the notice. + + Termination of your rights under this section does not terminate the + licenses of parties who have received copies or rights from you + under this License. If your rights have been terminated and not + permanently reinstated, receipt of a copy of some or all of the same + material does not give you any rights to use it. + +11. **FUTURE REVISIONS OF THIS LICENSE** + + 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/>. + + 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. + +12. **RELICENSING** + + “Massive Multiauthor Collaboration Site” (or “MMC Site”) means any + World Wide Web server that publishes copyrightable works and also + provides prominent facilities for anybody to edit those works. A + public wiki that anybody can edit is an example of such a server. A + “Massive Multiauthor Collaboration” (or “MMC”) contained in the site + means any set of copyrightable works thus published on the MMC site. + + “CC-BY-SA” means the Creative Commons Attribution-Share Alike 3.0 + license published by Creative Commons Corporation, a not-for-profit + corporation with a principal place of business in San Francisco, + California, as well as future copyleft versions of that license + published by that same organization. + + “Incorporate” means to publish or republish a Document, in whole or + in part, as part of another Document. + + An MMC is “eligible for relicensing” if it is licensed under this + License, and if all works that were first published under this + License somewhere other than this MMC, and subsequently incorporated + in whole or in part into the MMC, (1) had no cover texts or + invariant sections, and (2) were thus incorporated prior to November + 1, 2008. + + The operator of an MMC Site may republish an MMC contained in the + site under CC-BY-SA on the same site at any time before August 1, + 2009, provided the MMC is eligible for relicensing. + +#### ADDENDUM: How to use this License for your documents {#addendum-how-to-use-this-license-for-your-documents .heading} + +To use this License in a document you have written, include a copy of +the License in the document and put the following copyright and license +notices just after the title page: + +``` +Copyright (C) year your name. +Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.3 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A copy of the license is included in the section entitled "GNU Free Documentation License"". +``` + +If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, +replace the “with…Texts.” line with this: + +``` +with the Invariant Sections being list their titles, with the Front-Cover Texts being list, and with the Back-Cover Texts being list. +``` + +If you have Invariant Sections without Cover Texts, or some other +combination of the three, merge those two alternatives to suit the +situation. + +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. + |
