TODO: replace it to GFDL-1.1-or-later WITH no-invariant-sections + +.. _fdl: + +****************************** +GNU Free Documentation License +****************************** + + +.. _fdl-preamble: + +0. PREAMBLE +=========== + +The purpose of this License is to make a manual, textbook, or other +written 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. + +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. + + +.. _fdl-section1: + +1. APPLICABILITY AND DEFINITIONS +================================ + + +.. _fdl-document: + +This License applies to any manual or other work that contains a notice +placed by the copyright holder saying it can be distributed under the +terms of this License. The “Document”, below, refers to any such manual +or work. Any member of the public is a licensee, and is addressed as +“you”. + + +.. _fdl-modified: + +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. + + +.. _fdl-secondary: + +A “Secondary Section” is a named appendix or a front-matter section of +the :ref:`Document <fdl-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. (For example, 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. + + +.. _fdl-invariant: + +The “Invariant Sections” are certain +:ref:`Secondary Sections <fdl-secondary>` whose titles are designated, +as being those of Invariant Sections, in the notice that says that the +:ref:`Document <fdl-document>` is released under this License. + + +.. _fdl-cover-texts: + +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 +:ref:`Document <fdl-document>` is released under this License. + + +.. _fdl-transparent: + +A “Transparent” copy of the :ref:`Document <fdl-document>` means a +machine-readable copy, represented in a format whose specification is +available to the general public, whose contents can be viewed and edited +directly and 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 has been designed to thwart or discourage +subsequent modification by readers is not Transparent. 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 +designed for human modification. Opaque formats include PostScript, PDF, +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 produced by some +word processors for output purposes only. + + +.. _fdl-title-page: + +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. + + +.. _fdl-section2: + +2. VERBATIM COPYING +=================== + +You may copy and distribute the :ref:`Document <fdl-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 +:ref:`section 3 <fdl-section3>`. + +You may also lend copies, under the same conditions stated above, and +you may publicly display copies. + + +.. _fdl-section3: + +3. COPYING IN QUANTITY +====================== + +If you publish printed copies of the :ref:`Document <fdl-document>` +numbering more than 100, and the Document's license notice requires +:ref:`Cover Texts <fdl-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 +:ref:`Document <fdl-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 :ref:`Opaque <fdl-transparent>` copies of +the :ref:`Document <fdl-document>` numbering more than 100, you must +either include a machine-readable :ref:`Transparent <fdl-transparent>` +copy along with each Opaque copy, or state in or with each Opaque copy a +publicly-accessible computer-network location containing a complete +Transparent copy of the Document, free of added material, which the +general network-using public has access to download anonymously at no +charge using public-standard network protocols. 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 +:ref:`Document <fdl-document>` well before redistributing any large +number of copies, to give them a chance to provide you with an updated +version of the Document. + + +.. _fdl-section4: + +4. MODIFICATIONS +================ + +You may copy and distribute a :ref:`Modified Version <fdl-modified>` +of the :ref:`Document <fdl-document>` under the conditions of sections +:ref:`2 <fdl-section2>` and :ref:`3 <fdl-section3>` 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: + +- **A.** + Use in the :ref:`Title Page <fdl-title-page>` (and on the covers, + if any) a title distinct from that of the + :ref:`Document <fdl-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. + +- **B.** + List on the :ref:`Title Page <fdl-title-page>`, as authors, one or + more persons or entities responsible for authorship of the + modifications in the :ref:`Modified Version <fdl-modified>`, + together with at least five of the principal authors of the + :ref:`Document <fdl-document>` (all of its principal authors, if it + has less than five). + +- **C.** + State on the :ref:`Title Page <fdl-title-page>` the name of the + publisher of the :ref:`Modified Version <fdl-modified>`, as the + publisher. + +- **D.** + Preserve all the copyright notices of the + :ref:`Document <fdl-document>`. + +- **E.** + Add an appropriate copyright notice for your modifications adjacent + to the other copyright notices. + +- **F.** + Include, immediately after the copyright notices, a license notice + giving the public permission to use the + :ref:`Modified Version <fdl-modified>` under the terms of this + License, in the form shown in the Addendum below. + +- **G.** + Preserve in that license notice the full lists of + :ref:`Invariant Sections <fdl-invariant>` and required + :ref:`Cover Texts <fdl-cover-texts>` given in the + :ref:`Document's <fdl-document>` license notice. + +- **H.** + Include an unaltered copy of this License. + +- **I.** + Preserve the section entitled “History”, and its title, and add to it + an item stating at least the title, year, new authors, and publisher + of the :ref:`Modified Version <fdl-modified>` as given on the + :ref:`Title Page <fdl-title-page>`. If there is no section entitled + “History” in the :ref:`Document <fdl-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. + +- **J.** + Preserve the network location, if any, given in the + :ref:`Document <fdl-document>` for public access to a + :ref:`Transparent <fdl-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. + +- **K.** + In any section entitled “Acknowledgements” or “Dedications”, preserve + the section's title, and preserve in the section all the substance + and tone of each of the contributor acknowledgements and/or + dedications given therein. + +- **L.** + Preserve all the :ref:`Invariant Sections <fdl-invariant>` of the + :ref:`Document <fdl-document>`, unaltered in their text and in + their titles. Section numbers or the equivalent are not considered + part of the section titles. + +- **M.** + Delete any section entitled “Endorsements”. Such a section may not be + included in the :ref:`Modified Version <fdl-modified>`. + +- **N.** + Do not retitle any existing section as “Endorsements” or to conflict + in title with any :ref:`Invariant Section <fdl-invariant>`. + +If the :ref:`Modified Version <fdl-modified>` includes new +front-matter sections or appendices that qualify as +:ref:`Secondary Sections <fdl-secondary>` 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 :ref:`Invariant Sections <fdl-invariant>` 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 +:ref:`Modified Version <fdl-modified>` 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 +:ref:`Front-Cover Text <fdl-cover-texts>`, and a passage of up to 25 +words as a :ref:`Back-Cover Text <fdl-cover-texts>`, to the end of the +list of :ref:`Cover Texts <fdl-cover-texts>` in the +:ref:`Modified Version <fdl-modified>`. 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 +:ref:`Document <fdl-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 :ref:`Document <fdl-document>` +do not by this License give permission to use their names for publicity +for or to assert or imply endorsement of any +:ref:`Modified Version <fdl-modified>`. + + +.. _fdl-section5: + +5. COMBINING DOCUMENTS +====================== + +You may combine the :ref:`Document <fdl-document>` with other +documents released under this License, under the terms defined in +:ref:`section 4 <fdl-section4>` above for modified versions, provided +that you include in the combination all of the +:ref:`Invariant Sections <fdl-invariant>` of all of the original +documents, unmodified, and list them all as Invariant Sections of your +combined work in its license notice. + +The combined work need only contain one copy of this License, and +multiple identical :ref:`Invariant Sections <fdl-invariant>` 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.” + + +.. _fdl-section6: + +6. COLLECTIONS OF DOCUMENTS +=========================== + +You may make a collection consisting of the +:ref:`Document <fdl-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. + + +.. _fdl-section7: + +7. AGGREGATION WITH INDEPENDENT WORKS +===================================== + +A compilation of the :ref:`Document <fdl-document>` or its derivatives +with other separate and independent documents or works, in or on a +volume of a storage or distribution medium, does not as a whole count as +a :ref:`Modified Version <fdl-modified>` of the Document, provided no +compilation copyright is claimed for the compilation. Such a compilation +is called an “aggregate”, and this License does not apply to the other +self-contained works thus compiled with the Document , on account of +their being thus compiled, if they are not themselves derivative works +of the Document. If the :ref:`Cover Text <fdl-cover-texts>` +requirement of :ref:`section 3 <fdl-section3>` is applicable to these +copies of the Document, then if the Document is less than one quarter of +the entire aggregate, the Document's Cover Texts may be placed on covers +that surround only the Document within the aggregate. Otherwise they +must appear on covers around the whole aggregate. + + +.. _fdl-section8: + +8. TRANSLATION +============== + +Translation is considered a kind of modification, so you may distribute +translations of the :ref:`Document <fdl-document>` under the terms of +:ref:`section 4 <fdl-section4>`. Replacing +:ref:`Invariant Sections <fdl-invariant>` 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 provided that you also include the original +English version of this License. In case of a disagreement between the +translation and the original English version of this License, the +original English version will prevail. + + +.. _fdl-section9: + +9. TERMINATION +============== + +You may not copy, modify, sublicense, or distribute the +:ref:`Document <fdl-document>` except as expressly provided for under +this License. Any other attempt to copy, modify, sublicense or +distribute the Document is void, and will automatically terminate your +rights under this License. However, parties who have received copies, or +rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + +.. _fdl-section10: + +10. FUTURE REVISIONS OF THIS LICENSE +==================================== + +The `Free Software Foundation <http://www.gnu.org/fsf/fsf.html>`__ +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/ <http://www.gnu.org/copyleft>`__. + +Each version of the License is given a distinguishing version number. If +the :ref:`Document <fdl-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. + + +.. _fdl-using: + +Addendum +======== + +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 © YEAR YOUR NAME. + + Permission is granted to copy, distribute and/or modify this + document under the terms of the GNU Free Documentation License, + Version 1.1 or any later version published by the Free Software + Foundation; with the :ref:`Invariant Sections <fdl-invariant>` + being LIST THEIR TITLES, with the + :ref:`Front-Cover Texts <fdl-cover-texts>` being LIST, and with + the :ref:`Back-Cover Texts <fdl-cover-texts>` being LIST. A copy + of the license is included in the section entitled “GNU Free + Documentation License”. + +If you have no :ref:`Invariant Sections <fdl-invariant>`, write “with +no Invariant Sections” instead of saying which ones are invariant. If +you have no :ref:`Front-Cover Texts <fdl-cover-texts>`, write “no +Front-Cover Texts” instead of “Front-Cover Texts being LIST”; likewise +for :ref:`Back-Cover Texts <fdl-cover-texts>`. + +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 <http://www.gnu.org/copyleft/gpl.html>`__, +to permit their use in free software. |
