20 Everyone is permitted to copy and distribute verbatim copies
21 of this license document, but changing it is not allowed.

27 {\bf\small Preamble}
28 \end{center}
29 {\scriptsize
31 The purpose of this License is to make a manual, textbook, or other
32 functional and useful document ``free'' in the sense of freedom: to
33 assure everyone the effective freedom to copy and redistribute it,
34 with or without modifying it, either commercially or noncommercially.
35 Secondarily, this License preserves for the author and publisher a way
36 to get credit for their work, while not being considered responsible
37 for modifications made by others.
39 This License is a kind of ``copyleft'', which means that derivative
40 works of the document must themselves be free in the same sense. It
41 complements the GNU General Public License, which is a copyleft
42 license designed for free software.
44 We have designed this License in order to use it for manuals for free
45 software, because free software needs free documentation: a free
46 program should come with manuals providing the same freedoms that the
47 software does. But this License is not limited to software manuals;
48 it can be used for any textual work, regardless of subject matter or
49 whether it is published as a printed book. We recommend this License
50 principally for works whose purpose is instruction or reference.

54 {\small\bf 1. APPLICABILITY AND DEFINITIONS\par}
55 \phantomsection
56 %\addcontentsline{toc}{section}{1. APPLICABILITY AND DEFINITIONS}
57 \end{center}
59 {\scriptsize
61 This License applies to any manual or other work, in any medium, that
62 contains a notice placed by the copyright holder saying it can be
63 distributed under the terms of this License. Such a notice grants a
64 world-wide, royalty-free license, unlimited in duration, to use that
65 work under the conditions stated herein. The ``\textbf{Document}'', below,
66 refers to any such manual or work. Any member of the public is a
67 licensee, and is addressed as ``\textbf{you}''. You accept the license if you
68 copy, modify or distribute the work in a way requiring permission
69 under copyright law.
71 A ``\textbf{Modified Version}'' of the Document means any work containing the
72 Document or a portion of it, either copied verbatim, or with
73 modifications and/or translated into another language.
75 A ``\textbf{Secondary Section}'' is a named appendix or a front-matter section of
76 the Document that deals exclusively with the relationship of the
77 publishers or authors of the Document to the Document's overall subject
78 (or to related matters) and contains nothing that could fall directly
79 within that overall subject. (Thus, if the Document is in part a
80 textbook of mathematics, a Secondary Section may not explain any
81 mathematics.) The relationship could be a matter of historical
82 connection with the subject or with related matters, or of legal,
83 commercial, philosophical, ethical or political position regarding
84 them.
86 The ``\textbf{Invariant Sections}'' are certain Secondary Sections whose titles
87 are designated, as being those of Invariant Sections, in the notice
88 that says that the Document is released under this License. If a
89 section does not fit the above definition of Secondary then it is not
90 allowed to be designated as Invariant. The Document may contain zero
91 Invariant Sections. If the Document does not identify any Invariant
92 Sections then there are none.
94 The ``\textbf{Cover Texts}'' are certain short passages of text that are listed,
95 as Front-Cover Texts or Back-Cover Texts, in the notice that says that
96 the Document is released under this License. A Front-Cover Text may
97 be at most 5 words, and a Back-Cover Text may be at most 25 words.
99 A ``\textbf{Transparent}'' copy of the Document means a machine-readable copy,
100 represented in a format whose specification is available to the
101 general public, that is suitable for revising the document
102 straightforwardly with generic text editors or (for images composed of
103 pixels) generic paint programs or (for drawings) some widely available
104 drawing editor, and that is suitable for input to text formatters or
105 for automatic translation to a variety of formats suitable for input
106 to text formatters. A copy made in an otherwise Transparent file
107 format whose markup, or absence of markup, has been arranged to thwart
108 or discourage subsequent modification by readers is not Transparent.
109 An image format is not Transparent if used for any substantial amount
110 of text. A copy that is not ``Transparent'' is called ``\textbf{Opaque}''.
112 Examples of suitable formats for Transparent copies include plain
113 ASCII without markup, Texinfo input format, LaTeX input format, SGML
114 or XML using a publicly available DTD, and standard-conforming simple
115 HTML, PostScript or PDF designed for human modification. Examples of
116 transparent image formats include PNG, XCF and JPG. Opaque formats
117 include proprietary formats that can be read and edited only by
118 proprietary word processors, SGML or XML for which the DTD and/or
119 processing tools are not generally available, and the
120 machine-generated HTML, PostScript or PDF produced by some word
121 processors for output purposes only.
123 The ``\textbf{Title Page}'' means, for a printed book, the title page itself,
124 plus such following pages as are needed to hold, legibly, the material
125 this License requires to appear in the title page. For works in
126 formats which do not have any title page as such, ``Title Page'' means
127 the text near the most prominent appearance of the work's title,
128 preceding the beginning of the body of the text.
130 The ``\textbf{publisher}'' means any person or entity that distributes
131 copies of the Document to the public.
133 A section ``\textbf{Entitled XYZ}'' means a named subunit of the Document whose
134 title either is precisely XYZ or contains XYZ in parentheses following
135 text that translates XYZ in another language. (Here XYZ stands for a
136 specific section name mentioned below, such as ``\textbf{Acknowledgements}'',
137 ``\textbf{Dedications}'', ``\textbf{Endorsements}'', or ``\textbf{History}''.)
138 To ``\textbf{Preserve the Title}''
139 of such a section when you modify the Document means that it remains a
140 section ``Entitled XYZ'' according to this definition.
142 The Document may include Warranty Disclaimers next to the notice which
143 states that this License applies to the Document. These Warranty
144 Disclaimers are considered to be included by reference in this
145 License, but only as regards disclaiming warranties: any other
146 implication that these Warranty Disclaimers may have is void and has
147 no effect on the meaning of this License.

153 %\addcontentsline{toc}{section}{2. VERBATIM COPYING}
154 \end{center}
156 {\scriptsize
157 You may copy and distribute the Document in any medium, either
158 commercially or noncommercially, provided that this License, the
159 copyright notices, and the license notice saying this License applies
160 to the Document are reproduced in all copies, and that you add no other
161 conditions whatsoever to those of this License. You may not use
162 technical measures to obstruct or control the reading or further
163 copying of the copies you make or distribute. However, you may accept
164 compensation in exchange for copies. If you distribute a large enough
165 number of copies you must also follow the conditions in section~3.
167 You may also lend copies, under the same conditions stated above, and
168 you may publicly display copies.
171 \begin{center}
172 {\small\bf 3. COPYING IN QUANTITY\par}
173 \phantomsection
174 %\addcontentsline{toc}{section}{3. COPYING IN QUANTITY}
175 \end{center}
177 {\scriptsize
179 If you publish printed copies (or copies in media that commonly have
180 printed covers) of the Document, numbering more than 100, and the
181 Document's license notice requires Cover Texts, you must enclose the
182 copies in covers that carry, clearly and legibly, all these Cover
183 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
184 the back cover. Both covers must also clearly and legibly identify
185 you as the publisher of these copies. The front cover must present
186 the full title with all words of the title equally prominent and
187 visible. You may add other material on the covers in addition.
188 Copying with changes limited to the covers, as long as they preserve
189 the title of the Document and satisfy these conditions, can be treated
190 as verbatim copying in other respects.
192 If the required texts for either cover are too voluminous to fit
193 legibly, you should put the first ones listed (as many as fit
194 reasonably) on the actual cover, and continue the rest onto adjacent
195 pages.
197 If you publish or distribute Opaque copies of the Document numbering
198 more than 100, you must either include a machine-readable Transparent
199 copy along with each Opaque copy, or state in or with each Opaque copy
200 a computer-network location from which the general network-using
201 public has access to download using public-standard network protocols
202 a complete Transparent copy of the Document, free of added material.
203 If you use the latter option, you must take reasonably prudent steps,
204 when you begin distribution of Opaque copies in quantity, to ensure
205 that this Transparent copy will remain thus accessible at the stated
206 location until at least one year after the last time you distribute an
207 Opaque copy (directly or through your agents or retailers) of that
208 edition to the public.
210 It is requested, but not required, that you contact the authors of the
211 Document well before redistributing any large number of copies, to give
212 them a chance to provide you with an updated version of the Document.

216 {\small\bf 4. MODIFICATIONS\par}
217 \phantomsection
218 %\addcontentsline{toc}{section}{4. MODIFICATIONS}
219 \end{center}
221 {\scriptsize
223 You may copy and distribute a Modified Version of the Document under
224 the conditions of sections 2 and 3 above, provided that you release
225 the Modified Version under precisely this License, with the Modified
226 Version filling the role of the Document, thus licensing distribution
227 and modification of the Modified Version to whoever possesses a copy
228 of it. In addition, you must do these things in the Modified Version:
230 \begin{itemize}
231 \item[A.]
232 Use in the Title Page (and on the covers, if any) a title distinct
233 from that of the Document, and from those of previous versions
234 (which should, if there were any, be listed in the History section
235 of the Document). You may use the same title as a previous version
236 if the original publisher of that version gives permission.
238 \item[B.]
239 List on the Title Page, as authors, one or more persons or entities
240 responsible for authorship of the modifications in the Modified
241 Version, together with at least five of the principal authors of the
242 Document (all of its principal authors, if it has fewer than five),
243 unless they release you from this requirement.
245 \item[C.]
246 State on the Title page the name of the publisher of the
247 Modified Version, as the publisher.
249 \item[D.]
250 Preserve all the copyright notices of the Document.
252 \item[E.]
253 Add an appropriate copyright notice for your modifications
254 adjacent to the other copyright notices.
256 \item[F.]
257 Include, immediately after the copyright notices, a license notice
258 giving the public permission to use the Modified Version under the
259 terms of this License, in the form shown in the Addendum below.
261 \item[G.]
262 Preserve in that license notice the full lists of Invariant Sections
263 and required Cover Texts given in the Document's license notice.
265 \item[H.]
266 Include an unaltered copy of this License.
268 \item[I.]
269 Preserve the section Entitled ``History'', Preserve its Title, and add
270 to it an item stating at least the title, year, new authors, and
271 publisher of the Modified Version as given on the Title Page. If
272 there is no section Entitled ``History'' in the Document, create one
273 stating the title, year, authors, and publisher of the Document as
274 given on its Title Page, then add an item describing the Modified
275 Version as stated in the previous sentence.
277 \item[J.]
278 Preserve the network location, if any, given in the Document for
279 public access to a Transparent copy of the Document, and likewise
280 the network locations given in the Document for previous versions
281 it was based on. These may be placed in the ``History'' section.
282 You may omit a network location for a work that was published at
283 least four years before the Document itself, or if the original
284 publisher of the version it refers to gives permission.
286 \item[K.]
287 For any section Entitled ``Acknowledgements'' or ``Dedications'',
288 Preserve the Title of the section, and preserve in the section all
289 the substance and tone of each of the contributor acknowledgements
290 and/or dedications given therein.
292 \item[L.]
293 Preserve all the Invariant Sections of the Document,
294 unaltered in their text and in their titles. Section numbers
295 or the equivalent are not considered part of the section titles.
297 \item[M.]
298 Delete any section Entitled ``Endorsements''. Such a section
299 may not be included in the Modified Version.
301 \item[N.]
302 Do not retitle any existing section to be Entitled ``Endorsements''
303 or to conflict in title with any Invariant Section.
305 \item[O.]
306 Preserve any Warranty Disclaimers.
307 \end{itemize}
309 If the Modified Version includes new front-matter sections or
310 appendices that qualify as Secondary Sections and contain no material
311 copied from the Document, you may at your option designate some or all
312 of these sections as invariant. To do this, add their titles to the
313 list of Invariant Sections in the Modified Version's license notice.
314 These titles must be distinct from any other section titles.
316 You may add a section Entitled ``Endorsements'', provided it contains
317 nothing but endorsements of your Modified Version by various
318 parties---for example, statements of peer review or that the text has
319 been approved by an organization as the authoritative definition of a
320 standard.
322 You may add a passage of up to five words as a Front-Cover Text, and a
323 passage of up to 25 words as a Back-Cover Text, to the end of the list
324 of Cover Texts in the Modified Version. Only one passage of
325 Front-Cover Text and one of Back-Cover Text may be added by (or
326 through arrangements made by) any one entity. If the Document already
327 includes a cover text for the same cover, previously added by you or
328 by arrangement made by the same entity you are acting on behalf of,
329 you may not add another; but you may replace the old one, on explicit
330 permission from the previous publisher that added the old one.
332 The author(s) and publisher(s) of the Document do not by this License
333 give permission to use their names for publicity for or to assert or
334 imply endorsement of any Modified Version.

339 \phantomsection
340 %\addcontentsline{toc}{section}{5. COMBINING DOCUMENTS}
341 \end{center}
343 {\scriptsize
345 You may combine the Document with other documents released under this
346 License, under the terms defined in section~4 above for modified
347 versions, provided that you include in the combination all of the
348 Invariant Sections of all of the original documents, unmodified, and
349 list them all as Invariant Sections of your combined work in its
350 license notice, and that you preserve all their Warranty Disclaimers.
352 The combined work need only contain one copy of this License, and
353 multiple identical Invariant Sections may be replaced with a single
354 copy. If there are multiple Invariant Sections with the same name but
355 different contents, make the title of each such section unique by
356 adding at the end of it, in parentheses, the name of the original
357 author or publisher of that section if known, or else a unique number.
358 Make the same adjustment to the section titles in the list of
359 Invariant Sections in the license notice of the combined work.
361 In the combination, you must combine any sections Entitled ``History''
362 in the various original documents, forming one section Entitled
363 ``History''; likewise combine any sections Entitled ``Acknowledgements'',
364 and any sections Entitled ``Dedications''. You must delete all sections
365 Entitled ``Endorsements''.

375 You may make a collection consisting of the Document and other documents
376 released under this License, and replace the individual copies of this
377 License in the various documents with a single copy that is included in
378 the collection, provided that you follow the rules of this License for
379 verbatim copying of each of the documents in all other respects.
381 You may extract a single document from such a collection, and distribute
382 it individually under this License, provided you insert a copy of this
383 License into the extracted document, and follow this License in all
384 other respects regarding verbatim copying of that document.

391 \end{center}
393 {\scriptsize
395 A compilation of the Document or its derivatives with other separate
396 and independent documents or works, in or on a volume of a storage or
397 distribution medium, is called an ``aggregate'' if the copyright
398 resulting from the compilation is not used to limit the legal rights
399 of the compilation's users beyond what the individual works permit.
400 When the Document is included in an aggregate, this License does not
401 apply to the other works in the aggregate which are not themselves
402 derivative works of the Document.
404 If the Cover Text requirement of section~3 is applicable to these
405 copies of the Document, then if the Document is less than one half of
406 the entire aggregate, the Document's Cover Texts may be placed on
407 covers that bracket the Document within the aggregate, or the
408 electronic equivalent of covers if the Document is in electronic form.
409 Otherwise they must appear on printed covers that bracket the whole
410 aggregate.

414 {\small\bf 8. TRANSLATION\par}
415 \phantomsection
416 %\addcontentsline{toc}{section}{8. TRANSLATION}
417 \end{center}
419 {\scriptsize
421 Translation is considered a kind of modification, so you may
422 distribute translations of the Document under the terms of section~4.
423 Replacing Invariant Sections with translations requires special
424 permission from their copyright holders, but you may include
425 translations of some or all Invariant Sections in addition to the
426 original versions of these Invariant Sections. You may include a
427 translation of this License, and all the license notices in the
428 Document, and any Warranty Disclaimers, provided that you also include
429 the original English version of this License and the original versions
430 of those notices and disclaimers. In case of a disagreement between
431 the translation and the original version of this License or a notice
432 or disclaimer, the original version will prevail.
434 If a section in the Document is Entitled ``Acknowledgements'',
435 ``Dedications'', or ``History'', the requirement (section~4) to Preserve
436 its Title (section~1) will typically require changing the actual
437 title.

444 \end{center}
447 {\scriptsize
448 You may not copy, modify, sublicense, or distribute the Document
449 except as expressly provided under this License. Any attempt
450 otherwise to copy, modify, sublicense, or distribute it is void, and
451 will automatically terminate your rights under this License.
453 However, if you cease all violation of this License, then your license
454 from a particular copyright holder is reinstated (a) provisionally,
455 unless and until the copyright holder explicitly and finally
456 terminates your license, and (b) permanently, if the copyright holder
457 fails to notify you of the violation by some reasonable means prior to
458 60 days after the cessation.
460 Moreover, your license from a particular copyright holder is
461 reinstated permanently if the copyright holder notifies you of the
462 violation by some reasonable means, this is the first time you have
463 received notice of violation of this License (for any work) from that
464 copyright holder, and you cure the violation prior to 30 days after
465 your receipt of the notice.
467 Termination of your rights under this section does not terminate the
468 licenses of parties who have received copies or rights from you under
469 this License. If your rights have been terminated and not permanently
470 reinstated, receipt of a copy of some or all of the same material does
471 not give you any rights to use it.

482 The Free Software Foundation may publish new, revised versions
483 of the GNU Free Documentation License from time to time. Such new
484 versions will be similar in spirit to the present version, but may
485 differ in detail to address new problems or concerns. See
486 http://www.gnu.org/copyleft/.
488 Each version of the License is given a distinguishing version number.
489 If the Document specifies that a particular numbered version of this
490 License ``or any later version'' applies to it, you have the option of
491 following the terms and conditions either of that specified version or
492 of any later version that has been published (not as a draft) by the
493 Free Software Foundation. If the Document does not specify a version
494 number of this License, you may choose any version ever published (not
495 as a draft) by the Free Software Foundation. If the Document
496 specifies that a proxy can decide which future versions of this
497 License can be used, that proxy's public statement of acceptance of a
498 version permanently authorizes you to choose that version for the
499 Document.

510 ``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any
511 World Wide Web server that publishes copyrightable works and also
512 provides prominent facilities for anybody to edit those works. A
513 public wiki that anybody can edit is an example of such a server. A
514 ``Massive Multiauthor Collaboration'' (or ``MMC'') contained in the
515 site means any set of copyrightable works thus published on the MMC
516 site.
518 ``CC-BY-SA'' means the Creative Commons Attribution-Share Alike 3.0
519 license published by Creative Commons Corporation, a not-for-profit
520 corporation with a principal place of business in San Francisco,
521 California, as well as future copyleft versions of that license
522 published by that same organization.
524 ``Incorporate'' means to publish or republish a Document, in whole or
525 in part, as part of another Document.
527 An MMC is ``eligible for relicensing'' if it is licensed under this
528 License, and if all works that were first published under this License
529 somewhere other than this MMC, and subsequently incorporated in whole
530 or in part into the MMC, (1) had no cover texts or invariant sections,
531 and (2) were thus incorporated prior to November 1, 2008.
533 The operator of an MMC Site may republish an MMC contained in the site
534 under CC-BY-SA on the same site at any time before August 1, 2009,
535 provided the MMC is eligible for relicensing.

569 \bigskip
571 If you have Invariant Sections without Cover Texts, or some other
572 combination of the three, merge those two alternatives to suit the

575 If your document contains nontrivial examples of program code, we
576 recommend releasing these examples in parallel under your choice of
577 free software license, such as the GNU General Public License,
578 to permit their use in free software.
