COMMENT: - GNU Project - Free Software Foundation (FSF) + +.. COMMENT: LINK REV="made" HREF="mailto:webmasters@gnu.org" + +.. COMMENT: section> + <title>GNU Free Documentation License</title + +Version 1.1, March 2000 + + Copyright (C) 2000 Free Software Foundation, Inc. 51 Franklin Street, + Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and + distribute verbatim copies of this license document, but changing it is + not allowed. + +.. _gfdl-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. + +.. _gfdl-1: + +Applicability and Definition +############################ + +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". + +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. (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. + +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. + +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 "Transparent" copy of the 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. + +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. + +.. _gfdl-2: + +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. + +.. _gfdl-3: + +Copying in Quantity +################### + +If you publish printed copies 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 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 Document well before redistributing any large number of copies, to +give them a chance to provide you with an updated version of the +Document. + +.. _gfdl-4: + +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: + +#. 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. + +#. 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 less + than five). + +#. State on the Title page the name of the publisher of the + Modified Version, as the publisher. + +#. Preserve all the copyright notices of the Document. + +#. Add an appropriate copyright notice for your modifications + adjacent to the other copyright notices. + +#. 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. + +#. Preserve in that license notice the full lists of Invariant + Sections and required Cover Texts given in the Document's license + notice. + +#. Include an unaltered copy of this License. + +#. 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 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. + +#. 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. + +#. 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. + +#. 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. + +#. Delete any section entitled "Endorsements". Such a section may + not be included in the Modified Version. + +#. Do not retitle any existing section as "Endorsements" or to + conflict in title with any Invariant Section. + +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. + +.. _gfdl-5: + +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. + +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." + +.. _gfdl-6: + +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. + +.. _gfdl-7: + +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, does not as a whole count as a Modified +Version 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 Cover Text requirement of section 3 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. + +.. _gfdl-8: + +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 +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. + +.. _gfdl-9: + +Termination +########### + +You may not copy, modify, sublicense, or distribute the 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. + +.. _gfdl-10: + +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. + +.. _gfdl-howto: + +How to use this License for your documents +########################################## + +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 1.1 or any later version published by + the Free Software Foundation; with the Invariant Sections being LIST + THEIR TITLES, with the Front-Cover Texts being LIST, and with the + Back-Cover Texts being LIST. A copy of the license is included in the + section entitled "GNU Free Documentation License". + +If you have no Invariant Sections, write "with no Invariant +Sections" instead of saying which ones are invariant. If you have no +Front-Cover Texts, write "no Front-Cover Texts" instead of "Front-Cover +Texts being LIST"; likewise for Back-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, to permit their +use in free software. + |
