17 PREAMBLE | |
18 | |
19 The purpose of this License is to make a manual, textbook, or other | |
20 functional and useful document @dfn{free} in the sense of freedom: to | |
21 assure everyone the effective freedom to copy and redistribute it, | |
22 with or without modifying it, either commercially or noncommercially. | |
23 Secondarily, this License preserves for the author and publisher a way | |
24 to get credit for their work, while not being considered responsible | |
25 for modifications made by others. | |
26 | |
27 This License is a kind of ``copyleft'', which means that derivative | |
28 works of the document must themselves be free in the same sense. It | |
29 complements the GNU General Public License, which is a copyleft | |
30 license designed for free software. | |
31 | |
32 We have designed this License in order to use it for manuals for free | |
33 software, because free software needs free documentation: a free | |
34 program should come with manuals providing the same freedoms that the | |
35 software does. But this License is not limited to software manuals; | |
36 it can be used for any textual work, regardless of subject matter or | |
37 whether it is published as a printed book. We recommend this License | |
38 principally for works whose purpose is instruction or reference. | |
39 | |
40 @item | |
41 APPLICABILITY AND DEFINITIONS | |
42 | |
43 This License applies to any manual or other work, in any medium, that | |
44 contains a notice placed by the copyright holder saying it can be | |
45 distributed under the terms of this License. Such a notice grants a | |
46 world-wide, royalty-free license, unlimited in duration, to use that | |
47 work under the conditions stated herein. The ``Document'', below, | |
48 refers to any such manual or work. Any member of the public is a | |
49 licensee, and is addressed as ``you''. You accept the license if you | |
50 copy, modify or distribute the work in a way requiring permission | |
51 under copyright law. | |
52 | |
53 A ``Modified Version'' of the Document means any work containing the | |
54 Document or a portion of it, either copied verbatim, or with | |
55 modifications and/or translated into another language. | |
56 | |
57 A ``Secondary Section'' is a named appendix or a front-matter section | |
58 of the Document that deals exclusively with the relationship of the | |
59 publishers or authors of the Document to the Document's overall | |
60 subject (or to related matters) and contains nothing that could fall | |
61 directly within that overall subject. (Thus, if the Document is in | |
62 part a textbook of mathematics, a Secondary Section may not explain | |
63 any mathematics.) The relationship could be a matter of historical | |
64 connection with the subject or with related matters, or of legal, | |
65 commercial, philosophical, ethical or political position regarding | |
66 them. | |
67 | |
68 The ``Invariant Sections'' are certain Secondary Sections whose titles | |
69 are designated, as being those of Invariant Sections, in the notice | |
70 that says that the Document is released under this License. If a | |
71 section does not fit the above definition of Secondary then it is not | |
72 allowed to be designated as Invariant. The Document may contain zero | |
73 Invariant Sections. If the Document does not identify any Invariant | |
74 Sections then there are none. | |
75 | |
76 The ``Cover Texts'' are certain short passages of text that are listed, | |
77 as Front-Cover Texts or Back-Cover Texts, in the notice that says that | |
78 the Document is released under this License. A Front-Cover Text may | |
79 be at most 5 words, and a Back-Cover Text may be at most 25 words. | |
80 | |
81 A ``Transparent'' copy of the Document means a machine-readable copy, | |
82 represented in a format whose specification is available to the | |
83 general public, that is suitable for revising the document | |
84 straightforwardly with generic text editors or (for images composed of | |
85 pixels) generic paint programs or (for drawings) some widely available | |
86 drawing editor, and that is suitable for input to text formatters or | |
87 for automatic translation to a variety of formats suitable for input | |
88 to text formatters. A copy made in an otherwise Transparent file | |
89 format whose markup, or absence of markup, has been arranged to thwart | |
90 or discourage subsequent modification by readers is not Transparent. | |
91 An image format is not Transparent if used for any substantial amount | |
92 of text. A copy that is not ``Transparent'' is called ``Opaque''. | |
93 | |
94 Examples of suitable formats for Transparent copies include plain | |
13440 | 95 ASCII without markup, Texinfo input format, La@TeX{} input |
96 format, SGML or XML using a publicly available | |
97 DTD, and standard-conforming simple HTML, | |
98 PostScript or PDF designed for human modification. Examples | |
99 of transparent image formats include PNG, XCF and | |
17197 | 100 JPG@. Opaque formats include proprietary formats that can be |
13440 | 101 read and edited only by proprietary word processors, SGML or |
102 XML for which the DTD and/or processing tools are | |
103 not generally available, and the machine-generated HTML, | |
104 PostScript or PDF produced by some word processors for | |
10759 | 105 output purposes only. |
106 | |
107 The ``Title Page'' means, for a printed book, the title page itself, | |
108 plus such following pages as are needed to hold, legibly, the material | |
109 this License requires to appear in the title page. For works in | |
110 formats which do not have any title page as such, ``Title Page'' means | |
111 the text near the most prominent appearance of the work's title, | |
112 preceding the beginning of the body of the text. | |
113 | |
114 The ``publisher'' means any person or entity that distributes copies | |
115 of the Document to the public. | |
116 | |
117 A section ``Entitled XYZ'' means a named subunit of the Document whose | |
118 title either is precisely XYZ or contains XYZ in parentheses following | |
119 text that translates XYZ in another language. (Here XYZ stands for a | |
120 specific section name mentioned below, such as ``Acknowledgements'', | |
121 ``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title'' | |
122 of such a section when you modify the Document means that it remains a | |
123 section ``Entitled XYZ'' according to this definition. | |
124 | |
125 The Document may include Warranty Disclaimers next to the notice which | |
126 states that this License applies to the Document. These Warranty | |
127 Disclaimers are considered to be included by reference in this | |
128 License, but only as regards disclaiming warranties: any other | |
129 implication that these Warranty Disclaimers may have is void and has | |
130 no effect on the meaning of this License. | |
131 | |
132 @item | |
133 VERBATIM COPYING | |
134 | |
135 You may copy and distribute the Document in any medium, either | |
136 commercially or noncommercially, provided that this License, the | |
137 copyright notices, and the license notice saying this License applies | |
138 to the Document are reproduced in all copies, and that you add no other | |
139 conditions whatsoever to those of this License. You may not use | |
140 technical measures to obstruct or control the reading or further | |
141 copying of the copies you make or distribute. However, you may accept | |
142 compensation in exchange for copies. If you distribute a large enough | |
143 number of copies you must also follow the conditions in section 3. | |
144 | |
145 You may also lend copies, under the same conditions stated above, and | |
146 you may publicly display copies. | |
147 | |
148 @item | |
149 COPYING IN QUANTITY | |
150 | |
151 If you publish printed copies (or copies in media that commonly have | |
152 printed covers) of the Document, numbering more than 100, and the | |
153 Document's license notice requires Cover Texts, you must enclose the | |
154 copies in covers that carry, clearly and legibly, all these Cover | |
155 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on | |
156 the back cover. Both covers must also clearly and legibly identify | |
157 you as the publisher of these copies. The front cover must present | |
158 the full title with all words of the title equally prominent and | |
159 visible. You may add other material on the covers in addition. | |
160 Copying with changes limited to the covers, as long as they preserve | |
161 the title of the Document and satisfy these conditions, can be treated | |
162 as verbatim copying in other respects. | |
163 | |
164 If the required texts for either cover are too voluminous to fit | |
165 legibly, you should put the first ones listed (as many as fit | |
166 reasonably) on the actual cover, and continue the rest onto adjacent | |
167 pages. | |
168 | |
169 If you publish or distribute Opaque copies of the Document numbering | |
170 more than 100, you must either include a machine-readable Transparent | |
171 copy along with each Opaque copy, or state in or with each Opaque copy | |
172 a computer-network location from which the general network-using | |
173 public has access to download using public-standard network protocols | |
174 a complete Transparent copy of the Document, free of added material. | |
175 If you use the latter option, you must take reasonably prudent steps, | |
176 when you begin distribution of Opaque copies in quantity, to ensure | |
177 that this Transparent copy will remain thus accessible at the stated | |
178 location until at least one year after the last time you distribute an | |
179 Opaque copy (directly or through your agents or retailers) of that | |
180 edition to the public. | |
181 | |
182 It is requested, but not required, that you contact the authors of the | |
183 Document well before redistributing any large number of copies, to give | |
184 them a chance to provide you with an updated version of the Document. | |
185 | |
186 @item | |
187 MODIFICATIONS | |
188 | |
189 You may copy and distribute a Modified Version of the Document under | |
190 the conditions of sections 2 and 3 above, provided that you release | |
191 the Modified Version under precisely this License, with the Modified | |
192 Version filling the role of the Document, thus licensing distribution | |
193 and modification of the Modified Version to whoever possesses a copy | |
194 of it. In addition, you must do these things in the Modified Version: | |
195 | |
196 @enumerate A | |
197 @item | |
198 Use in the Title Page (and on the covers, if any) a title distinct | |
199 from that of the Document, and from those of previous versions | |
200 (which should, if there were any, be listed in the History section | |
201 of the Document). You may use the same title as a previous version | |
202 if the original publisher of that version gives permission. | |
203 | |
204 @item | |
205 List on the Title Page, as authors, one or more persons or entities | |
206 responsible for authorship of the modifications in the Modified | |
207 Version, together with at least five of the principal authors of the | |
208 Document (all of its principal authors, if it has fewer than five), | |
209 unless they release you from this requirement. | |
210 | |
211 @item | |
212 State on the Title page the name of the publisher of the | |
213 Modified Version, as the publisher. | |
214 | |
215 @item | |
216 Preserve all the copyright notices of the Document. | |
217 | |
218 @item | |
219 Add an appropriate copyright notice for your modifications | |
220 adjacent to the other copyright notices. | |
221 | |
222 @item | |
223 Include, immediately after the copyright notices, a license notice | |
224 giving the public permission to use the Modified Version under the | |
225 terms of this License, in the form shown in the Addendum below. | |
226 | |
227 @item | |
228 Preserve in that license notice the full lists of Invariant Sections | |
229 and required Cover Texts given in the Document's license notice. | |
230 | |
231 @item | |
232 Include an unaltered copy of this License. | |
233 | |
234 @item | |
235 Preserve the section Entitled ``History'', Preserve its Title, and add | |
236 to it an item stating at least the title, year, new authors, and | |
237 publisher of the Modified Version as given on the Title Page. If | |
238 there is no section Entitled ``History'' in the Document, create one | |
239 stating the title, year, authors, and publisher of the Document as | |
240 given on its Title Page, then add an item describing the Modified | |
241 Version as stated in the previous sentence. | |
242 | |
243 @item | |
244 Preserve the network location, if any, given in the Document for | |
245 public access to a Transparent copy of the Document, and likewise | |
246 the network locations given in the Document for previous versions | |
247 it was based on. These may be placed in the ``History'' section. | |
248 You may omit a network location for a work that was published at | |
249 least four years before the Document itself, or if the original | |
250 publisher of the version it refers to gives permission. | |
251 | |
252 @item | |
253 For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve | |
254 the Title of the section, and preserve in the section all the | |
255 substance and tone of each of the contributor acknowledgements and/or | |
256 dedications given therein. | |
257 | |
258 @item | |
259 Preserve all the Invariant Sections of the Document, | |
260 unaltered in their text and in their titles. Section numbers | |
261 or the equivalent are not considered part of the section titles. | |
262 | |
263 @item | |
264 Delete any section Entitled ``Endorsements''. Such a section | |
265 may not be included in the Modified Version. | |
266 | |
267 @item | |
268 Do not retitle any existing section to be Entitled ``Endorsements'' or | |
269 to conflict in title with any Invariant Section. | |
270 | |
271 @item | |
272 Preserve any Warranty Disclaimers. | |
273 @end enumerate | |
274 | |
275 If the Modified Version includes new front-matter sections or | |
276 appendices that qualify as Secondary Sections and contain no material | |
277 copied from the Document, you may at your option designate some or all | |
278 of these sections as invariant. To do this, add their titles to the | |
279 list of Invariant Sections in the Modified Version's license notice. | |
280 These titles must be distinct from any other section titles. | |
281 | |
282 You may add a section Entitled ``Endorsements'', provided it contains | |
283 nothing but endorsements of your Modified Version by various | |
284 parties---for example, statements of peer review or that the text has | |
285 been approved by an organization as the authoritative definition of a | |
286 standard. | |
287 | |
288 You may add a passage of up to five words as a Front-Cover Text, and a | |
289 passage of up to 25 words as a Back-Cover Text, to the end of the list | |
290 of Cover Texts in the Modified Version. Only one passage of | |
291 Front-Cover Text and one of Back-Cover Text may be added by (or | |
292 through arrangements made by) any one entity. If the Document already | |
293 includes a cover text for the same cover, previously added by you or | |
294 by arrangement made by the same entity you are acting on behalf of, | |
295 you may not add another; but you may replace the old one, on explicit | |
296 permission from the previous publisher that added the old one. | |
297 | |
298 The author(s) and publisher(s) of the Document do not by this License | |
299 give permission to use their names for publicity for or to assert or | |
300 imply endorsement of any Modified Version. | |
301 | |
302 @item | |
303 COMBINING DOCUMENTS | |
304 | |
305 You may combine the Document with other documents released under this | |
306 License, under the terms defined in section 4 above for modified | |
307 versions, provided that you include in the combination all of the | |
308 Invariant Sections of all of the original documents, unmodified, and | |
309 list them all as Invariant Sections of your combined work in its | |
310 license notice, and that you preserve all their Warranty Disclaimers. | |
311 | |
312 The combined work need only contain one copy of this License, and | |
313 multiple identical Invariant Sections may be replaced with a single | |
314 copy. If there are multiple Invariant Sections with the same name but | |
315 different contents, make the title of each such section unique by | |
316 adding at the end of it, in parentheses, the name of the original | |
317 author or publisher of that section if known, or else a unique number. | |
318 Make the same adjustment to the section titles in the list of | |
319 Invariant Sections in the license notice of the combined work. | |
320 | |
321 In the combination, you must combine any sections Entitled ``History'' | |
322 in the various original documents, forming one section Entitled | |
323 ``History''; likewise combine any sections Entitled ``Acknowledgements'', | |
324 and any sections Entitled ``Dedications''. You must delete all | |
325 sections Entitled ``Endorsements.'' | |
326 | |
327 @item | |
328 COLLECTIONS OF DOCUMENTS | |
329 | |
330 You may make a collection consisting of the Document and other documents | |
331 released under this License, and replace the individual copies of this | |
332 License in the various documents with a single copy that is included in | |
333 the collection, provided that you follow the rules of this License for | |
334 verbatim copying of each of the documents in all other respects. | |
335 | |
336 You may extract a single document from such a collection, and distribute | |
337 it individually under this License, provided you insert a copy of this | |
338 License into the extracted document, and follow this License in all | |
339 other respects regarding verbatim copying of that document. | |
340 | |
341 @item | |
342 AGGREGATION WITH INDEPENDENT WORKS | |
343 | |
344 A compilation of the Document or its derivatives with other separate | |
345 and independent documents or works, in or on a volume of a storage or | |
346 distribution medium, is called an ``aggregate'' if the copyright | |
347 resulting from the compilation is not used to limit the legal rights | |
348 of the compilation's users beyond what the individual works permit. | |
349 When the Document is included in an aggregate, this License does not | |
350 apply to the other works in the aggregate which are not themselves | |
351 derivative works of the Document. | |
352 | |
353 If the Cover Text requirement of section 3 is applicable to these | |
354 copies of the Document, then if the Document is less than one half of | |
355 the entire aggregate, the Document's Cover Texts may be placed on | |
356 covers that bracket the Document within the aggregate, or the | |
357 electronic equivalent of covers if the Document is in electronic form. | |
358 Otherwise they must appear on printed covers that bracket the whole | |
359 aggregate. | |
360 | |
361 @item | |
362 TRANSLATION | |
363 | |
364 Translation is considered a kind of modification, so you may | |
365 distribute translations of the Document under the terms of section 4. | |
366 Replacing Invariant Sections with translations requires special | |
367 permission from their copyright holders, but you may include | |
368 translations of some or all Invariant Sections in addition to the | |
369 original versions of these Invariant Sections. You may include a | |
370 translation of this License, and all the license notices in the | |
371 Document, and any Warranty Disclaimers, provided that you also include | |
372 the original English version of this License and the original versions | |
373 of those notices and disclaimers. In case of a disagreement between | |
374 the translation and the original version of this License or a notice | |
375 or disclaimer, the original version will prevail. | |
376 | |
377 If a section in the Document is Entitled ``Acknowledgements'', | |
378 ``Dedications'', or ``History'', the requirement (section 4) to Preserve | |
379 its Title (section 1) will typically require changing the actual | |
380 title. | |
381 | |
382 @item | |
383 TERMINATION | |
384 | |
385 You may not copy, modify, sublicense, or distribute the Document | |
386 except as expressly provided under this License. Any attempt | |
387 otherwise to copy, modify, sublicense, or distribute it is void, and | |
388 will automatically terminate your rights under this License. | |
389 | |
390 However, if you cease all violation of this License, then your license | |
391 from a particular copyright holder is reinstated (a) provisionally, | |
392 unless and until the copyright holder explicitly and finally | |
393 terminates your license, and (b) permanently, if the copyright holder | |
394 fails to notify you of the violation by some reasonable means prior to | |
395 60 days after the cessation. | |
396 | |
397 Moreover, your license from a particular copyright holder is | |
398 reinstated permanently if the copyright holder notifies you of the | |
399 violation by some reasonable means, this is the first time you have | |
400 received notice of violation of this License (for any work) from that | |
401 copyright holder, and you cure the violation prior to 30 days after | |
402 your receipt of the notice. | |
403 | |
404 Termination of your rights under this section does not terminate the | |
405 licenses of parties who have received copies or rights from you under | |
406 this License. If your rights have been terminated and not permanently | |
407 reinstated, receipt of a copy of some or all of the same material does | |
408 not give you any rights to use it. | |
409 | |
410 @item | |
411 FUTURE REVISIONS OF THIS LICENSE | |
412 | |
413 The Free Software Foundation may publish new, revised versions | |
414 of the GNU Free Documentation License from time to time. Such new | |
415 versions will be similar in spirit to the present version, but may | |
416 differ in detail to address new problems or concerns. See | |
19222 | 417 @uref{https://www.gnu.org/licenses/}. |
10759 | 418 |
419 Each version of the License is given a distinguishing version number. | |
420 If the Document specifies that a particular numbered version of this | |
421 License ``or any later version'' applies to it, you have the option of | |
422 following the terms and conditions either of that specified version or | |
423 of any later version that has been published (not as a draft) by the | |
424 Free Software Foundation. If the Document does not specify a version | |
425 number of this License, you may choose any version ever published (not | |
426 as a draft) by the Free Software Foundation. If the Document | |
427 specifies that a proxy can decide which future versions of this | |
428 License can be used, that proxy's public statement of acceptance of a | |
429 version permanently authorizes you to choose that version for the | |
430 Document. | |
431 | |
432 @item | |
433 RELICENSING | |
434 | |
435 ``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any | |
436 World Wide Web server that publishes copyrightable works and also | |
437 provides prominent facilities for anybody to edit those works. A | |
438 public wiki that anybody can edit is an example of such a server. A | |
439 ``Massive Multiauthor Collaboration'' (or ``MMC'') contained in the | |
440 site means any set of copyrightable works thus published on the MMC | |
441 site. | |
442 | |
443 ``CC-BY-SA'' means the Creative Commons Attribution-Share Alike 3.0 | |
444 license published by Creative Commons Corporation, a not-for-profit | |
445 corporation with a principal place of business in San Francisco, | |
446 California, as well as future copyleft versions of that license | |
447 published by that same organization. | |
448 | |
449 ``Incorporate'' means to publish or republish a Document, in whole or | |
450 in part, as part of another Document. | |
451 | |
452 An MMC is ``eligible for relicensing'' if it is licensed under this | |
453 License, and if all works that were first published under this License | |
454 somewhere other than this MMC, and subsequently incorporated in whole | |
455 or in part into the MMC, (1) had no cover texts or invariant sections, | |
456 and (2) were thus incorporated prior to November 1, 2008. | |
457 | |
458 The operator of an MMC Site may republish an MMC contained in the site | |
459 under CC-BY-SA on the same site at any time before August 1, 2009, | |
460 provided the MMC is eligible for relicensing. | |
