76 Everyone is permitted to copy and distribute verbatim copies
77 of this license document, but changing it is not allowed.
83 <p>The purpose of this License is to make a manual, textbook, or other
84 functional and useful document <em>free</em> in the sense of freedom: to
85 assure everyone the effective freedom to copy and redistribute it,
86 with or without modifying it, either commercially or noncommercially.
87 Secondarily, this License preserves for the author and publisher a way
88 to get credit for their work, while not being considered responsible
89 for modifications made by others.
91 <p>This License is a kind of “copyleft”, which means that derivative
92 works of the document must themselves be free in the same sense. It
93 complements the GNU General Public License, which is a copyleft
94 license designed for free software.
96 <p>We have designed this License in order to use it for manuals for free
97 software, because free software needs free documentation: a free
98 program should come with manuals providing the same freedoms that the
99 software does. But this License is not limited to software manuals;
100 it can be used for any textual work, regardless of subject matter or
101 whether it is published as a printed book. We recommend this License
102 principally for works whose purpose is instruction or reference.
104 </li><li> APPLICABILITY AND DEFINITIONS
106 <p>This License applies to any manual or other work, in any medium, that
107 contains a notice placed by the copyright holder saying it can be
108 distributed under the terms of this License. Such a notice grants a
109 world-wide, royalty-free license, unlimited in duration, to use that
110 work under the conditions stated herein. The “Document”, below,
111 refers to any such manual or work. Any member of the public is a
112 licensee, and is addressed as “you”. You accept the license if you
113 copy, modify or distribute the work in a way requiring permission
116 <p>A “Modified Version” of the Document means any work containing the
117 Document or a portion of it, either copied verbatim, or with
118 modifications and/or translated into another language.
120 <p>A “Secondary Section” is a named appendix or a front-matter section
121 of the Document that deals exclusively with the relationship of the
122 publishers or authors of the Document to the Document’s overall
123 subject (or to related matters) and contains nothing that could fall
124 directly within that overall subject. (Thus, if the Document is in
125 part a textbook of mathematics, a Secondary Section may not explain
126 any mathematics.) The relationship could be a matter of historical
127 connection with the subject or with related matters, or of legal,
128 commercial, philosophical, ethical or political position regarding
131 <p>The “Invariant Sections” are certain Secondary Sections whose titles
132 are designated, as being those of Invariant Sections, in the notice
133 that says that the Document is released under this License. If a
134 section does not fit the above definition of Secondary then it is not
135 allowed to be designated as Invariant. The Document may contain zero
136 Invariant Sections. If the Document does not identify any Invariant
137 Sections then there are none.
139 <p>The “Cover Texts” are certain short passages of text that are listed,
140 as Front-Cover Texts or Back-Cover Texts, in the notice that says that
141 the Document is released under this License. A Front-Cover Text may
142 be at most 5 words, and a Back-Cover Text may be at most 25 words.
144 <p>A “Transparent” copy of the Document means a machine-readable copy,
145 represented in a format whose specification is available to the
146 general public, that is suitable for revising the document
147 straightforwardly with generic text editors or (for images composed of
148 pixels) generic paint programs or (for drawings) some widely available
149 drawing editor, and that is suitable for input to text formatters or
150 for automatic translation to a variety of formats suitable for input
151 to text formatters. A copy made in an otherwise Transparent file
152 format whose markup, or absence of markup, has been arranged to thwart
153 or discourage subsequent modification by readers is not Transparent.
154 An image format is not Transparent if used for any substantial amount
155 of text. A copy that is not “Transparent” is called “Opaque”.
157 <p>Examples of suitable formats for Transparent copies include plain
158 <small>ASCII</small> without markup, Texinfo input format, LaTeX input
159 format, <acronym>SGML</acronym> or <acronym>XML</acronym> using a publicly available
160 <acronym>DTD</acronym>, and standard-conforming simple <acronym>HTML</acronym>,
161 PostScript or <acronym>PDF</acronym> designed for human modification. Examples
162 of transparent image formats include <acronym>PNG</acronym>, <acronym>XCF</acronym> and
163 <acronym>JPG</acronym>. Opaque formats include proprietary formats that can be
164 read and edited only by proprietary word processors, <acronym>SGML</acronym> or
165 <acronym>XML</acronym> for which the <acronym>DTD</acronym> and/or processing tools are
166 not generally available, and the machine-generated <acronym>HTML</acronym>,
167 PostScript or <acronym>PDF</acronym> produced by some word processors for
168 output purposes only.
170 <p>The “Title Page” means, for a printed book, the title page itself,
171 plus such following pages as are needed to hold, legibly, the material
172 this License requires to appear in the title page. For works in
173 formats which do not have any title page as such, “Title Page” means
174 the text near the most prominent appearance of the work’s title,
175 preceding the beginning of the body of the text.
177 <p>A section “Entitled XYZ” means a named subunit of the Document whose
178 title either is precisely XYZ or contains XYZ in parentheses following
179 text that translates XYZ in another language. (Here XYZ stands for a
180 specific section name mentioned below, such as “Acknowledgements”,
181 “Dedications”, “Endorsements”, or “History”.) To “Preserve the Title”
182 of such a section when you modify the Document means that it remains a
183 section “Entitled XYZ” according to this definition.
185 <p>The Document may include Warranty Disclaimers next to the notice which
186 states that this License applies to the Document. These Warranty
187 Disclaimers are considered to be included by reference in this
188 License, but only as regards disclaiming warranties: any other
189 implication that these Warranty Disclaimers may have is void and has
190 no effect on the meaning of this License.
192 </li><li> VERBATIM COPYING
194 <p>You may copy and distribute the Document in any medium, either
195 commercially or noncommercially, provided that this License, the
196 copyright notices, and the license notice saying this License applies
197 to the Document are reproduced in all copies, and that you add no other
198 conditions whatsoever to those of this License. You may not use
199 technical measures to obstruct or control the reading or further
200 copying of the copies you make or distribute. However, you may accept
201 compensation in exchange for copies. If you distribute a large enough
202 number of copies you must also follow the conditions in section 3.
204 <p>You may also lend copies, under the same conditions stated above, and
205 you may publicly display copies.
207 </li><li> COPYING IN QUANTITY
209 <p>If you publish printed copies (or copies in media that commonly have
210 printed covers) of the Document, numbering more than 100, and the
211 Document’s license notice requires Cover Texts, you must enclose the
212 copies in covers that carry, clearly and legibly, all these Cover
213 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
214 the back cover. Both covers must also clearly and legibly identify
215 you as the publisher of these copies. The front cover must present
216 the full title with all words of the title equally prominent and
217 visible. You may add other material on the covers in addition.
218 Copying with changes limited to the covers, as long as they preserve
219 the title of the Document and satisfy these conditions, can be treated
220 as verbatim copying in other respects.
222 <p>If the required texts for either cover are too voluminous to fit
223 legibly, you should put the first ones listed (as many as fit
224 reasonably) on the actual cover, and continue the rest onto adjacent
227 <p>If you publish or distribute Opaque copies of the Document numbering
228 more than 100, you must either include a machine-readable Transparent
229 copy along with each Opaque copy, or state in or with each Opaque copy
230 a computer-network location from which the general network-using
231 public has access to download using public-standard network protocols
232 a complete Transparent copy of the Document, free of added material.
233 If you use the latter option, you must take reasonably prudent steps,
234 when you begin distribution of Opaque copies in quantity, to ensure
235 that this Transparent copy will remain thus accessible at the stated
236 location until at least one year after the last time you distribute an
237 Opaque copy (directly or through your agents or retailers) of that
238 edition to the public.
240 <p>It is requested, but not required, that you contact the authors of the
241 Document well before redistributing any large number of copies, to give
242 them a chance to provide you with an updated version of the Document.
244 </li><li> MODIFICATIONS
246 <p>You may copy and distribute a Modified Version of the Document under
247 the conditions of sections 2 and 3 above, provided that you release
248 the Modified Version under precisely this License, with the Modified
249 Version filling the role of the Document, thus licensing distribution
250 and modification of the Modified Version to whoever possesses a copy
251 of it. In addition, you must do these things in the Modified Version:
254 <li> Use in the Title Page (and on the covers, if any) a title distinct
255 from that of the Document, and from those of previous versions
256 (which should, if there were any, be listed in the History section
257 of the Document). You may use the same title as a previous version
258 if the original publisher of that version gives permission.
260 </li><li> List on the Title Page, as authors, one or more persons or entities
261 responsible for authorship of the modifications in the Modified
262 Version, together with at least five of the principal authors of the
263 Document (all of its principal authors, if it has fewer than five),
264 unless they release you from this requirement.
266 </li><li> State on the Title page the name of the publisher of the
267 Modified Version, as the publisher.
269 </li><li> Preserve all the copyright notices of the Document.
271 </li><li> Add an appropriate copyright notice for your modifications
272 adjacent to the other copyright notices.
274 </li><li> Include, immediately after the copyright notices, a license notice
275 giving the public permission to use the Modified Version under the
276 terms of this License, in the form shown in the Addendum below.
278 </li><li> Preserve in that license notice the full lists of Invariant Sections
279 and required Cover Texts given in the Document’s license notice.
281 </li><li> Include an unaltered copy of this License.
283 </li><li> Preserve the section Entitled “History”, Preserve its Title, and add
284 to it an item stating at least the title, year, new authors, and
285 publisher of the Modified Version as given on the Title Page. If
286 there is no section Entitled “History” in the Document, create one
287 stating the title, year, authors, and publisher of the Document as
288 given on its Title Page, then add an item describing the Modified
289 Version as stated in the previous sentence.
291 </li><li> Preserve the network location, if any, given in the Document for
292 public access to a Transparent copy of the Document, and likewise
293 the network locations given in the Document for previous versions
294 it was based on. These may be placed in the “History” section.
295 You may omit a network location for a work that was published at
296 least four years before the Document itself, or if the original
297 publisher of the version it refers to gives permission.
299 </li><li> For any section Entitled “Acknowledgements” or “Dedications”, Preserve
300 the Title of the section, and preserve in the section all the
301 substance and tone of each of the contributor acknowledgements and/or
302 dedications given therein.
304 </li><li> Preserve all the Invariant Sections of the Document,
305 unaltered in their text and in their titles. Section numbers
306 or the equivalent are not considered part of the section titles.
308 </li><li> Delete any section Entitled “Endorsements”. Such a section
309 may not be included in the Modified Version.
311 </li><li> Do not retitle any existing section to be Entitled “Endorsements” or
312 to conflict in title with any Invariant Section.
314 </li><li> Preserve any Warranty Disclaimers.
317 <p>If the Modified Version includes new front-matter sections or
318 appendices that qualify as Secondary Sections and contain no material
319 copied from the Document, you may at your option designate some or all
320 of these sections as invariant. To do this, add their titles to the
321 list of Invariant Sections in the Modified Version’s license notice.
322 These titles must be distinct from any other section titles.
324 <p>You may add a section Entitled “Endorsements”, provided it contains
325 nothing but endorsements of your Modified Version by various
326 parties—for example, statements of peer review or that the text has
327 been approved by an organization as the authoritative definition of a
330 <p>You may add a passage of up to five words as a Front-Cover Text, and a
331 passage of up to 25 words as a Back-Cover Text, to the end of the list
332 of Cover Texts in the Modified Version. Only one passage of
333 Front-Cover Text and one of Back-Cover Text may be added by (or
334 through arrangements made by) any one entity. If the Document already
335 includes a cover text for the same cover, previously added by you or
336 by arrangement made by the same entity you are acting on behalf of,
337 you may not add another; but you may replace the old one, on explicit
338 permission from the previous publisher that added the old one.
340 <p>The author(s) and publisher(s) of the Document do not by this License
341 give permission to use their names for publicity for or to assert or
342 imply endorsement of any Modified Version.
344 </li><li> COMBINING DOCUMENTS
346 <p>You may combine the Document with other documents released under this
347 License, under the terms defined in section 4 above for modified
348 versions, provided that you include in the combination all of the
349 Invariant Sections of all of the original documents, unmodified, and
350 list them all as Invariant Sections of your combined work in its
351 license notice, and that you preserve all their Warranty Disclaimers.
353 <p>The combined work need only contain one copy of this License, and
354 multiple identical Invariant Sections may be replaced with a single
355 copy. If there are multiple Invariant Sections with the same name but
356 different contents, make the title of each such section unique by
357 adding at the end of it, in parentheses, the name of the original
358 author or publisher of that section if known, or else a unique number.
359 Make the same adjustment to the section titles in the list of
360 Invariant Sections in the license notice of the combined work.
362 <p>In the combination, you must combine any sections Entitled “History”
363 in the various original documents, forming one section Entitled
364 “History”; likewise combine any sections Entitled “Acknowledgements”,
365 and any sections Entitled “Dedications”. You must delete all
366 sections Entitled “Endorsements.”
368 </li><li> COLLECTIONS OF DOCUMENTS
370 <p>You may make a collection consisting of the Document and other documents
371 released under this License, and replace the individual copies of this
372 License in the various documents with a single copy that is included in
373 the collection, provided that you follow the rules of this License for
374 verbatim copying of each of the documents in all other respects.
376 <p>You may extract a single document from such a collection, and distribute
377 it individually under this License, provided you insert a copy of this
378 License into the extracted document, and follow this License in all
379 other respects regarding verbatim copying of that document.
381 </li><li> AGGREGATION WITH INDEPENDENT WORKS
383 <p>A compilation of the Document or its derivatives with other separate
384 and independent documents or works, in or on a volume of a storage or
385 distribution medium, is called an “aggregate” if the copyright
386 resulting from the compilation is not used to limit the legal rights
387 of the compilation’s users beyond what the individual works permit.
388 When the Document is included in an aggregate, this License does not
389 apply to the other works in the aggregate which are not themselves
390 derivative works of the Document.
392 <p>If the Cover Text requirement of section 3 is applicable to these
393 copies of the Document, then if the Document is less than one half of
394 the entire aggregate, the Document’s Cover Texts may be placed on
395 covers that bracket the Document within the aggregate, or the
396 electronic equivalent of covers if the Document is in electronic form.
397 Otherwise they must appear on printed covers that bracket the whole
400 </li><li> TRANSLATION
402 <p>Translation is considered a kind of modification, so you may
403 distribute translations of the Document under the terms of section 4.
404 Replacing Invariant Sections with translations requires special
405 permission from their copyright holders, but you may include
406 translations of some or all Invariant Sections in addition to the
407 original versions of these Invariant Sections. You may include a
408 translation of this License, and all the license notices in the
409 Document, and any Warranty Disclaimers, provided that you also include
410 the original English version of this License and the original versions
411 of those notices and disclaimers. In case of a disagreement between
412 the translation and the original version of this License or a notice
413 or disclaimer, the original version will prevail.
415 <p>If a section in the Document is Entitled “Acknowledgements”,
416 “Dedications”, or “History”, the requirement (section 4) to Preserve
417 its Title (section 1) will typically require changing the actual
420 </li><li> TERMINATION
422 <p>You may not copy, modify, sublicense, or distribute the Document except
423 as expressly provided for under this License. Any other attempt to
424 copy, modify, sublicense or distribute the Document is void, and will
425 automatically terminate your rights under this License. However,
426 parties who have received copies, or rights, from you under this
427 License will not have their licenses terminated so long as such
428 parties remain in full compliance.
430 </li><li> FUTURE REVISIONS OF THIS LICENSE
432 <p>The Free Software Foundation may publish new, revised versions
433 of the GNU Free Documentation License from time to time. Such new
434 versions will be similar in spirit to the present version, but may
435 differ in detail to address new problems or concerns. See
436 <a href="http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</a>.
438 <p>Each version of the License is given a distinguishing version number.
439 If the Document specifies that a particular numbered version of this
440 License “or any later version” applies to it, you have the option of
441 following the terms and conditions either of that specified version or
442 of any later version that has been published (not as a draft) by the
443 Free Software Foundation. If the Document does not specify a version
444 number of this License, you may choose any version ever published (not
445 as a draft) by the Free Software Foundation.
448 <a name="ADDENDUM_003a-How-to-use-this-License-for-your-documents"></a>
449 <h4 class="appendixsubsec">A.1.1 ADDENDUM: How to use this License for your documents</h4>
451 <p>To use this License in a document you have written, include a copy of
452 the License in the document and put the following copyright and
453 license notices just after the title page:
455 <div class="smallexample">
456 <pre class="smallexample"> Copyright (C) <var>year</var> <var>your name</var>.
457 Permission is granted to copy, distribute and/or modify this document
458 under the terms of the GNU Free Documentation License, Version 1.2
459 or any later version published by the Free Software Foundation;
460 with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
461 Texts. A copy of the license is included in the section entitled ``GNU
462 Free Documentation License''.
465 <p>If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
466 replace the “with...Texts.” line with this:
468 <div class="smallexample">
469 <pre class="smallexample"> with the Invariant Sections being <var>list their titles</var>, with
470 the Front-Cover Texts being <var>list</var>, and with the Back-Cover Texts
471 being <var>list</var>.
474 <p>If you have Invariant Sections without Cover Texts, or some other
475 combination of the three, merge those two alternatives to suit the
478 <p>If your document contains nontrivial examples of program code, we
479 recommend releasing these examples in parallel under your choice of
480 free software license, such as the GNU General Public License,
481 to permit their use in free software.
