41\subsection*{Preamble}
42The purpose of this License is to make a manual, textbook, or other
43functional and useful document ``free'' in the sense of freedom: to
44assure everyone the effective freedom to copy and redistribute it,
45with or without modifying it, either commercially or noncommercially.
46Secondarily, this License preserves for the author and publisher a way
47to get credit for their work, while not being considered responsible
48for modifications made by others.
49
50This License is a kind of ``copyleft'', which means that derivative
51works of the document must themselves be free in the same sense. It
52complements the GNU General Public License, which is a copyleft
53license designed for free software.
54
55We have designed this License in order to use it for manuals for free
56software, because free software needs free documentation: a free
57program should come with manuals providing the same freedoms that the
58software does. But this License is not limited to software manuals;
59it can be used for any textual work, regardless of subject matter or
60whether it is published as a printed book. We recommend this License
61principally for works whose purpose is instruction or reference.
62
63
64\subsection*{1. APPLICABILITY AND DEFINITIONS}
65This License applies to any manual or other work, in any medium, that
66contains a notice placed by the copyright holder saying it can be
67distributed under the terms of this License. Such a notice grants a
68world-wide, royalty-free license, unlimited in duration, to use that
69work under the conditions stated herein. The \textbf{``Document''}, below,
70refers to any such manual or work. Any member of the public is a
71licensee, and is addressed as \textbf{``you''}. You accept the license if you
72copy, modify or distribute the work in a way requiring permission
73under copyright law.
74
75A \textbf{``Modified Version''} of the Document means any work containing the
76Document or a portion of it, either copied verbatim, or with
77modifications and/or translated into another language.
78
79A \textbf{``Secondary Section''} is a named appendix or a front-matter section of
80the Document that deals exclusively with the relationship of the
81publishers or authors of the Document to the Document's overall subject
82(or to related matters) and contains nothing that could fall directly
83within that overall subject. (Thus, if the Document is in part a
84textbook of mathematics, a Secondary Section may not explain any
85mathematics.) The relationship could be a matter of historical
86connection with the subject or with related matters, or of legal,
87commercial, philosophical, ethical or political position regarding
88them.
89
90The \textbf{``Invariant Sections''} are certain Secondary Sections whose titles
91are designated, as being those of Invariant Sections, in the notice
92that says that the Document is released under this License. If a
93section does not fit the above definition of Secondary then it is not
94allowed to be designated as Invariant. The Document may contain zero
95Invariant Sections. If the Document does not identify any Invariant
96Sections then there are none.
97
98The \textbf{``Cover Texts''} are certain short passages of text that are listed,
99as Front-Cover Texts or Back-Cover Texts, in the notice that says that
100the Document is released under this License. A Front-Cover Text may
101be at most 5 words, and a Back-Cover Text may be at most 25 words.
102
103A \textbf{``Transparent''} copy of the Document means a machine-readable copy,
104represented in a format whose specification is available to the
105general public, that is suitable for revising the document
106straightforwardly with generic text editors or (for images composed of
107pixels) generic paint programs or (for drawings) some widely available
108drawing editor, and that is suitable for input to text formatters or
109for automatic translation to a variety of formats suitable for input
110to text formatters. A copy made in an otherwise Transparent file
111format whose markup, or absence of markup, has been arranged to thwart
112or discourage subsequent modification by readers is not Transparent.
113An image format is not Transparent if used for any substantial amount
114of text. A copy that is not ``Transparent'' is called \textbf{``Opaque''}.
115
116Examples of suitable formats for Transparent copies include plain
117ASCII without markup, Texinfo input format, LaTeX input format, SGML
118or XML using a publicly available DTD, and standard-conforming simple
119HTML, PostScript or PDF designed for human modification. Examples of
120transparent image formats include PNG, XCF and JPG. Opaque formats
121include proprietary formats that can be read and edited only by
122proprietary word processors, SGML or XML for which the DTD and/or
123processing tools are not generally available, and the
124machine-generated HTML, PostScript or PDF produced by some word
125processors for output purposes only.
126
127The \textbf{``Title Page''} means, for a printed book, the title page itself,
128plus such following pages as are needed to hold, legibly, the material
129this License requires to appear in the title page. For works in
130formats which do not have any title page as such, ``Title Page'' means
131the text near the most prominent appearance of the work's title,
132preceding the beginning of the body of the text.
133
134A section \textbf{``Entitled XYZ''} means a named subunit of the Document whose
135title either is precisely XYZ or contains XYZ in parentheses following
136text that translates XYZ in another language. (Here XYZ stands for a
137specific section name mentioned below, such as \textbf{``Acknowledgements''},
138\textbf{``Dedications''}, \textbf{``Endorsements''}, or \textbf{``History''}.)
139To \textbf{``Preserve the Title''}
140of such a section when you modify the Document means that it remains a
141section ``Entitled XYZ'' according to this definition.
142
143The Document may include Warranty Disclaimers next to the notice which
144states that this License applies to the Document. These Warranty
145Disclaimers are considered to be included by reference in this
146License, but only as regards disclaiming warranties: any other
147implication that these Warranty Disclaimers may have is void and has
148no effect on the meaning of this License.
149
150
151\subsection*{2. VERBATIM COPYING}
152You may copy and distribute the Document in any medium, either
153commercially or noncommercially, provided that this License, the
154copyright notices, and the license notice saying this License applies
155to the Document are reproduced in all copies, and that you add no other
156conditions whatsoever to those of this License. You may not use
157technical measures to obstruct or control the reading or further
158copying of the copies you make or distribute. However, you may accept
159compensation in exchange for copies. If you distribute a large enough
160number of copies you must also follow the conditions in section 3.
161
162You may also lend copies, under the same conditions stated above, and
163you may publicly display copies.
164
165
166\subsection*{3. COPYING IN QUANTITY}
167If you publish printed copies (or copies in media that commonly have
168printed covers) of the Document, numbering more than 100, and the
169Document's license notice requires Cover Texts, you must enclose the
170copies in covers that carry, clearly and legibly, all these Cover
171Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
172the back cover. Both covers must also clearly and legibly identify
173you as the publisher of these copies. The front cover must present
174the full title with all words of the title equally prominent and
175visible. You may add other material on the covers in addition.
176Copying with changes limited to the covers, as long as they preserve
177the title of the Document and satisfy these conditions, can be treated
178as verbatim copying in other respects.
179
180If the required texts for either cover are too voluminous to fit
181legibly, you should put the first ones listed (as many as fit
182reasonably) on the actual cover, and continue the rest onto adjacent
183pages.
184
185If you publish or distribute Opaque copies of the Document numbering
186more than 100, you must either include a machine-readable Transparent
187copy along with each Opaque copy, or state in or with each Opaque copy
188a computer-network location from which the general network-using
189public has access to download using public-standard network protocols
190a complete Transparent copy of the Document, free of added material.
191If you use the latter option, you must take reasonably prudent steps,
192when you begin distribution of Opaque copies in quantity, to ensure
193that this Transparent copy will remain thus accessible at the stated
194location until at least one year after the last time you distribute an
195Opaque copy (directly or through your agents or retailers) of that
196edition to the public.
197
198It is requested, but not required, that you contact the authors of the
199Document well before redistributing any large number of copies, to give
200them a chance to provide you with an updated version of the Document.
201
202
203
204\subsection*{4. MODIFICATIONS}
205You may copy and distribute a Modified Version of the Document under
206the conditions of sections 2 and 3 above, provided that you release
207the Modified Version under precisely this License, with the Modified
208Version filling the role of the Document, thus licensing distribution
209and modification of the Modified Version to whoever possesses a copy
210of it. In addition, you must do these things in the Modified Version:
211
212\begin{itemize}
213\item[A.]
214 Use in the Title Page (and on the covers, if any) a title distinct
215 from that of the Document, and from those of previous versions
216 (which should, if there were any, be listed in the History section
217 of the Document). You may use the same title as a previous version
218 if the original publisher of that version gives permission.
219
220\item[B.]
221 List on the Title Page, as authors, one or more persons or entities
222 responsible for authorship of the modifications in the Modified
223 Version, together with at least five of the principal authors of the
224 Document (all of its principal authors, if it has fewer than five),
225 unless they release you from this requirement.
226
227\item[C.]
228 State on the Title page the name of the publisher of the
229 Modified Version, as the publisher.
230
231\item[D.]
232 Preserve all the copyright notices of the Document.
233
234\item[E.]
235 Add an appropriate copyright notice for your modifications
236 adjacent to the other copyright notices.
237
238\item[F.]
239 Include, immediately after the copyright notices, a license notice
240 giving the public permission to use the Modified Version under the
241 terms of this License, in the form shown in the Addendum below.
242
243\item[G.]
244 Preserve in that license notice the full lists of Invariant Sections
245 and required Cover Texts given in the Document's license notice.
246
247\item[H.]
248 Include an unaltered copy of this License.
249
250\item[I.]
251 Preserve the section Entitled ``History'', Preserve its Title, and add
252 to it an item stating at least the title, year, new authors, and
253 publisher of the Modified Version as given on the Title Page. If
254 there is no section Entitled ``History'' in the Document, create one
255 stating the title, year, authors, and publisher of the Document as
256 given on its Title Page, then add an item describing the Modified
257 Version as stated in the previous sentence.
258
259\item[J.]
260 Preserve the network location, if any, given in the Document for
261 public access to a Transparent copy of the Document, and likewise
262 the network locations given in the Document for previous versions
263 it was based on. These may be placed in the ``History'' section.
264 You may omit a network location for a work that was published at
265 least four years before the Document itself, or if the original
266 publisher of the version it refers to gives permission.
267
268\item[K.]
269 For any section Entitled ``Acknowledgements'' or ``Dedications'',
270 Preserve the Title of the section, and preserve in the section all
271 the substance and tone of each of the contributor acknowledgements
272 and/or dedications given therein.
273
274\item[L.]
275 Preserve all the Invariant Sections of the Document,
276 unaltered in their text and in their titles. Section numbers
277 or the equivalent are not considered part of the section titles.
278
279\item[M.]
280 Delete any section Entitled ``Endorsements''. Such a section
281 may not be included in the Modified Version.
282
283\item[N.]
284 Do not retitle any existing section to be Entitled ``Endorsements''
285 or to conflict in title with any Invariant Section.
286
287\item[O.]
288 Preserve any Warranty Disclaimers.
289\end{itemize}
290
291If the Modified Version includes new front-matter sections or
292appendices that qualify as Secondary Sections and contain no material
293copied from the Document, you may at your option designate some or all
294of these sections as invariant. To do this, add their titles to the
295list of Invariant Sections in the Modified Version's license notice.
296These titles must be distinct from any other section titles.
297
298You may add a section Entitled ``Endorsements'', provided it contains
299nothing but endorsements of your Modified Version by various
300parties--for example, statements of peer review or that the text has
301been approved by an organization as the authoritative definition of a
302standard.
303
304You may add a passage of up to five words as a Front-Cover Text, and a
305passage of up to 25 words as a Back-Cover Text, to the end of the list
306of Cover Texts in the Modified Version. Only one passage of
307Front-Cover Text and one of Back-Cover Text may be added by (or
308through arrangements made by) any one entity. If the Document already
309includes a cover text for the same cover, previously added by you or
310by arrangement made by the same entity you are acting on behalf of,
311you may not add another; but you may replace the old one, on explicit
312permission from the previous publisher that added the old one.
313
314The author(s) and publisher(s) of the Document do not by this License
315give permission to use their names for publicity for or to assert or
316imply endorsement of any Modified Version.
317
318
319\subsection*{5. COMBINING DOCUMENTS}
320You may combine the Document with other documents released under this
321License, under the terms defined in section 4 above for modified
322versions, provided that you include in the combination all of the
323Invariant Sections of all of the original documents, unmodified, and
324list them all as Invariant Sections of your combined work in its
325license notice, and that you preserve all their Warranty Disclaimers.
326
327The combined work need only contain one copy of this License, and
328multiple identical Invariant Sections may be replaced with a single
329copy. If there are multiple Invariant Sections with the same name but
330different contents, make the title of each such section unique by
331adding at the end of it, in parentheses, the name of the original
332author or publisher of that section if known, or else a unique number.
333Make the same adjustment to the section titles in the list of
334Invariant Sections in the license notice of the combined work.
335
336In the combination, you must combine any sections Entitled ``History''
337in the various original documents, forming one section Entitled
338``History''; likewise combine any sections Entitled ``Acknowledgements'',
339and any sections Entitled ``Dedications''. You must delete all sections
340Entitled ``Endorsements''.
341
342\subsection*{6. COLLECTIONS OF DOCUMENTS}
343You may make a collection consisting of the Document and other documents
344released under this License, and replace the individual copies of this
345License in the various documents with a single copy that is included in
346the collection, provided that you follow the rules of this License for
347verbatim copying of each of the documents in all other respects.
348
349You may extract a single document from such a collection, and distribute
350it individually under this License, provided you insert a copy of this
351License into the extracted document, and follow this License in all
352other respects regarding verbatim copying of that document.
353
354
355\subsection*{7. AGGREGATION WITH INDEPENDENT WORKS}
356A compilation of the Document or its derivatives with other separate
357and independent documents or works, in or on a volume of a storage or
358distribution medium, is called an ``aggregate'' if the copyright
359resulting from the compilation is not used to limit the legal rights
360of the compilation's users beyond what the individual works permit.
361When the Document is included in an aggregate, this License does not
362apply to the other works in the aggregate which are not themselves
363derivative works of the Document.
364
365If the Cover Text requirement of section 3 is applicable to these
366copies of the Document, then if the Document is less than one half of
367the entire aggregate, the Document's Cover Texts may be placed on
368covers that bracket the Document within the aggregate, or the
369electronic equivalent of covers if the Document is in electronic form.
370Otherwise they must appear on printed covers that bracket the whole
371aggregate.
372
373
374\subsection*{8. TRANSLATION}
375Translation is considered a kind of modification, so you may
376distribute translations of the Document under the terms of section 4.
377Replacing Invariant Sections with translations requires special
378permission from their copyright holders, but you may include
379translations of some or all Invariant Sections in addition to the
380original versions of these Invariant Sections. You may include a
381translation of this License, and all the license notices in the
382Document, and any Warranty Disclaimers, provided that you also include
383the original English version of this License and the original versions
384of those notices and disclaimers. In case of a disagreement between
385the translation and the original version of this License or a notice
386or disclaimer, the original version will prevail.
387
388If a section in the Document is Entitled ``Acknowledgements'',
389``Dedications'', or ``History'', the requirement (section 4) to Preserve
390its Title (section 1) will typically require changing the actual
391title.
392
393\subsection*{9. TERMINATION}
394You may not copy, modify, sublicense, or distribute the Document except
395as expressly provided for under this License. Any other attempt to
396copy, modify, sublicense or distribute the Document is void, and will
397automatically terminate your rights under this License. However,
398parties who have received copies, or rights, from you under this
399License will not have their licenses terminated so long as such
400parties remain in full compliance.
401
402\subsection*{10. FUTURE REVISIONS OF THIS LICENSE}
403The Free Software Foundation may publish new, revised versions
404of the GNU Free Documentation License from time to time. Such new
405versions will be similar in spirit to the present version, but may
406differ in detail to address new problems or concerns. See
407http://www.gnu.org/copyleft/.
408
409Each version of the License is given a distinguishing version number.
410If the Document specifies that a particular numbered version of this
411License ``or any later version'' applies to it, you have the option of
412following the terms and conditions either of that specified version or
413of any later version that has been published (not as a draft) by the
414Free Software Foundation. If the Document does not specify a version
415number of this License, you may choose any version ever published (not
416as a draft) by the Free Software Foundation.
417
418
419\subsection*{ADDENDUM: How to use this License for your documents}
420To use this License in a document you have written, include a copy of
421the License in the document and put the following copyright and
422license notices just after the title page:
423
424\bigskip
425\begin{quote}
426 Copyright \copyright YEAR YOUR NAME.
427 Permission is granted to copy, distribute and/or modify this document
428 under the terms of the GNU Free Documentation License, Version 1.2
429 or any later version published by the Free Software Foundation;
430 with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
431 A copy of the license is included in the section entitled ``GNU
432 Free Documentation License''.
433\end{quote}
434\bigskip
435
436If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
437replace the ``with \ldots\ Texts.'' line with this:
438
439\bigskip
440\begin{quote}
441 with the Invariant Sections being LIST THEIR TITLES, with the
442 Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
443\end{quote}
444\bigskip
445
446If you have Invariant Sections without Cover Texts, or some other
447combination of the three, merge those two alternatives to suit the
448situation.
449
450If your document contains nontrivial examples of program code, we
451recommend releasing these examples in parallel under your choice of
452free software license, such as the GNU General Public License,
453to permit their use in free software.
