54 PREAMBLE |
|
55 |
|
56 The purpose of this License is to make a manual, textbook, or other |
|
57 functional and useful document @dfn{free} in the sense of freedom: to |
|
58 assure everyone the effective freedom to copy and redistribute it, |
|
59 with or without modifying it, either commercially or noncommercially. |
|
60 Secondarily, this License preserves for the author and publisher a way |
|
61 to get credit for their work, while not being considered responsible |
|
62 for modifications made by others. |
|
63 |
|
64 This License is a kind of ``copyleft'', which means that derivative |
|
65 works of the document must themselves be free in the same sense. It |
|
66 complements the GNU General Public License, which is a copyleft |
|
67 license designed for free software. |
|
68 |
|
69 We have designed this License in order to use it for manuals for free |
|
70 software, because free software needs free documentation: a free |
|
71 program should come with manuals providing the same freedoms that the |
|
72 software does. But this License is not limited to software manuals; |
|
73 it can be used for any textual work, regardless of subject matter or |
|
74 whether it is published as a printed book. We recommend this License |
|
75 principally for works whose purpose is instruction or reference. |
|

|
77 @item |
|
78 APPLICABILITY AND DEFINITIONS |
|
79 |
|
80 This License applies to any manual or other work, in any medium, that |
|
81 contains a notice placed by the copyright holder saying it can be |
|
82 distributed under the terms of this License. Such a notice grants a |
|
83 world-wide, royalty-free license, unlimited in duration, to use that |
|
84 work under the conditions stated herein. The ``Document'', below, |
|
85 refers to any such manual or work. Any member of the public is a |
|
86 licensee, and is addressed as ``you''. You accept the license if you |
|
87 copy, modify or distribute the work in a way requiring permission |
|
88 under copyright law. |
|
89 |
|
90 A ``Modified Version'' of the Document means any work containing the |
|
91 Document or a portion of it, either copied verbatim, or with |
|
92 modifications and/or translated into another language. |
|
93 |
|
94 A ``Secondary Section'' is a named appendix or a front-matter section |
|
95 of the Document that deals exclusively with the relationship of the |
|
96 publishers or authors of the Document to the Document's overall |
|
97 subject (or to related matters) and contains nothing that could fall |
|
98 directly within that overall subject. (Thus, if the Document is in |
|
99 part a textbook of mathematics, a Secondary Section may not explain |
|
100 any mathematics.) The relationship could be a matter of historical |
|
101 connection with the subject or with related matters, or of legal, |
|
102 commercial, philosophical, ethical or political position regarding |
|
103 them. |
|
104 |
|
105 The ``Invariant Sections'' are certain Secondary Sections whose titles |
|
106 are designated, as being those of Invariant Sections, in the notice |
|
107 that says that the Document is released under this License. If a |
|
108 section does not fit the above definition of Secondary then it is not |
|
109 allowed to be designated as Invariant. The Document may contain zero |
|
110 Invariant Sections. If the Document does not identify any Invariant |
|
111 Sections then there are none. |
|
112 |
|
113 The ``Cover Texts'' are certain short passages of text that are listed, |
|
114 as Front-Cover Texts or Back-Cover Texts, in the notice that says that |
|
115 the Document is released under this License. A Front-Cover Text may |
|
116 be at most 5 words, and a Back-Cover Text may be at most 25 words. |
|
117 |
|
118 A ``Transparent'' copy of the Document means a machine-readable copy, |
|
119 represented in a format whose specification is available to the |
|
120 general public, that is suitable for revising the document |
|
121 straightforwardly with generic text editors or (for images composed of |
|
122 pixels) generic paint programs or (for drawings) some widely available |
|
123 drawing editor, and that is suitable for input to text formatters or |
|
124 for automatic translation to a variety of formats suitable for input |
|
125 to text formatters. A copy made in an otherwise Transparent file |
|
126 format whose markup, or absence of markup, has been arranged to thwart |
|
127 or discourage subsequent modification by readers is not Transparent. |
|
128 An image format is not Transparent if used for any substantial amount |
|
129 of text. A copy that is not ``Transparent'' is called ``Opaque''. |
|
130 |
|
131 Examples of suitable formats for Transparent copies include plain |
|
132 @sc{ascii} without markup, Texinfo input format, La@TeX{} input |
|
133 format, @acronym{SGML} or @acronym{XML} using a publicly available |
|
134 @acronym{DTD}, and standard-conforming simple @acronym{HTML}, |
|
135 PostScript or @acronym{PDF} designed for human modification. Examples |
|
136 of transparent image formats include @acronym{PNG}, @acronym{XCF} and |
|
137 @acronym{JPG}. Opaque formats include proprietary formats that can be |
|
138 read and edited only by proprietary word processors, @acronym{SGML} or |
|
139 @acronym{XML} for which the @acronym{DTD} and/or processing tools are |
|
140 not generally available, and the machine-generated @acronym{HTML}, |
|
141 PostScript or @acronym{PDF} produced by some word processors for |
|
142 output purposes only. |
|
143 |
|
144 The ``Title Page'' means, for a printed book, the title page itself, |
|
145 plus such following pages as are needed to hold, legibly, the material |
|
146 this License requires to appear in the title page. For works in |
|
147 formats which do not have any title page as such, ``Title Page'' means |
|
148 the text near the most prominent appearance of the work's title, |
|
149 preceding the beginning of the body of the text. |
|
150 |
|
151 A section ``Entitled XYZ'' means a named subunit of the Document whose |
|
152 title either is precisely XYZ or contains XYZ in parentheses following |
|
153 text that translates XYZ in another language. (Here XYZ stands for a |
|
154 specific section name mentioned below, such as ``Acknowledgements'', |
|
155 ``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title'' |
|
156 of such a section when you modify the Document means that it remains a |
|
157 section ``Entitled XYZ'' according to this definition. |
|
158 |
|
159 The Document may include Warranty Disclaimers next to the notice which |
|
160 states that this License applies to the Document. These Warranty |
|
161 Disclaimers are considered to be included by reference in this |
|
162 License, but only as regards disclaiming warranties: any other |
|
163 implication that these Warranty Disclaimers may have is void and has |
|
164 no effect on the meaning of this License. |
|
165 |
|
166 @item |
|
167 VERBATIM COPYING |
|
168 |
|
169 You may copy and distribute the Document in any medium, either |
|
170 commercially or noncommercially, provided that this License, the |
|
171 copyright notices, and the license notice saying this License applies |
|
172 to the Document are reproduced in all copies, and that you add no other |
|
173 conditions whatsoever to those of this License. You may not use |
|
174 technical measures to obstruct or control the reading or further |
|
175 copying of the copies you make or distribute. However, you may accept |
|
176 compensation in exchange for copies. If you distribute a large enough |
|
177 number of copies you must also follow the conditions in section 3. |
|
178 |
|
179 You may also lend copies, under the same conditions stated above, and |
|
180 you may publicly display copies. |
|
181 |
|
182 @item |
|
183 COPYING IN QUANTITY |
|
184 |
|
185 If you publish printed copies (or copies in media that commonly have |
|
186 printed covers) of the Document, numbering more than 100, and the |
|
187 Document's license notice requires Cover Texts, you must enclose the |
|
188 copies in covers that carry, clearly and legibly, all these Cover |
|
189 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on |
|
190 the back cover. Both covers must also clearly and legibly identify |
|
191 you as the publisher of these copies. The front cover must present |
|
192 the full title with all words of the title equally prominent and |
|
193 visible. You may add other material on the covers in addition. |
|
194 Copying with changes limited to the covers, as long as they preserve |
|
195 the title of the Document and satisfy these conditions, can be treated |
|
196 as verbatim copying in other respects. |
|
197 |
|
198 If the required texts for either cover are too voluminous to fit |
|
199 legibly, you should put the first ones listed (as many as fit |
|
200 reasonably) on the actual cover, and continue the rest onto adjacent |
|
201 pages. |
|
202 |
|
203 If you publish or distribute Opaque copies of the Document numbering |
|
204 more than 100, you must either include a machine-readable Transparent |
|
205 copy along with each Opaque copy, or state in or with each Opaque copy |
|
206 a computer-network location from which the general network-using |
|
207 public has access to download using public-standard network protocols |
|
208 a complete Transparent copy of the Document, free of added material. |
|
209 If you use the latter option, you must take reasonably prudent steps, |
|
210 when you begin distribution of Opaque copies in quantity, to ensure |
|
211 that this Transparent copy will remain thus accessible at the stated |
|
212 location until at least one year after the last time you distribute an |
|
213 Opaque copy (directly or through your agents or retailers) of that |
|
214 edition to the public. |
|
215 |
|
216 It is requested, but not required, that you contact the authors of the |
|
217 Document well before redistributing any large number of copies, to give |
|
218 them a chance to provide you with an updated version of the Document. |
|
219 |
|
220 @item |
|
221 MODIFICATIONS |
|
222 |
|
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: |
|
229 |
|
230 @enumerate A |
|
231 @item |
|
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. |
|
237 |
|
238 @item |
|
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. |
|
244 |
|
245 @item |
|
246 State on the Title page the name of the publisher of the |
|
247 Modified Version, as the publisher. |

250 Preserve all the copyright notices of the Document. |

253 Add an appropriate copyright notice for your modifications |
|
254 adjacent to the other copyright notices. |
|
255 |
|
256 @item |
|
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. |
|
260 |
|
261 @item |
|
262 Preserve in that license notice the full lists of Invariant Sections |
|
263 and required Cover Texts given in the Document's license notice. |

264 |

265 @item |
|
266 Include an unaltered copy of this License. |
|
267 |

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. |
|
276 |
|
277 @item |
|
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. |
|
285 |
|
286 @item |
|
287 For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve |
|
288 the Title of the section, and preserve in the section all the |
|
289 substance and tone of each of the contributor acknowledgements and/or |
|
290 dedications given therein. |
|
291 |
|
292 @item |
|
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. |
|
296 |
|
297 @item |
|
298 Delete any section Entitled ``Endorsements''. Such a section |
|
299 may not be included in the Modified Version. |
|
300 |
|
301 @item |
|
302 Do not retitle any existing section to be Entitled ``Endorsements'' or |
|
303 to conflict in title with any Invariant Section. |
|
304 |
|
305 @item |
|
306 Preserve any Warranty Disclaimers. |
|
307 @end enumerate |
|
308 |
|
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. |
|
315 |
|
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. |
|
321 |
|
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. |
|
331 |
|
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. |
|
335 |
|
336 @item |
|
337 COMBINING DOCUMENTS |
|
338 |
|
339 You may combine the Document with other documents released under this |
|
340 License, under the terms defined in section 4 above for modified |
|
341 versions, provided that you include in the combination all of the |
|
342 Invariant Sections of all of the original documents, unmodified, and |
|
343 list them all as Invariant Sections of your combined work in its |
|
344 license notice, and that you preserve all their Warranty Disclaimers. |
|
345 |
|
346 The combined work need only contain one copy of this License, and |
|
347 multiple identical Invariant Sections may be replaced with a single |
|
348 copy. If there are multiple Invariant Sections with the same name but |
|
349 different contents, make the title of each such section unique by |
|
350 adding at the end of it, in parentheses, the name of the original |
|
351 author or publisher of that section if known, or else a unique number. |
|
352 Make the same adjustment to the section titles in the list of |
|
353 Invariant Sections in the license notice of the combined work. |
|
354 |
|
355 In the combination, you must combine any sections Entitled ``History'' |
|
356 in the various original documents, forming one section Entitled |
|
357 ``History''; likewise combine any sections Entitled ``Acknowledgements'', |
|
358 and any sections Entitled ``Dedications''. You must delete all |
|
359 sections Entitled ``Endorsements.'' |
|

361 @item |
|
362 COLLECTIONS OF DOCUMENTS |
|
363 |
|
364 You may make a collection consisting of the Document and other documents |
|
365 released under this License, and replace the individual copies of this |
|
366 License in the various documents with a single copy that is included in |
|
367 the collection, provided that you follow the rules of this License for |
|
368 verbatim copying of each of the documents in all other respects. |
|
369 |
|
370 You may extract a single document from such a collection, and distribute |
|
371 it individually under this License, provided you insert a copy of this |
|
372 License into the extracted document, and follow this License in all |
|
373 other respects regarding verbatim copying of that document. |
|
374 |
|
375 @item |
|
376 AGGREGATION WITH INDEPENDENT WORKS |
|
377 |
|
378 A compilation of the Document or its derivatives with other separate |
|
379 and independent documents or works, in or on a volume of a storage or |
|
380 distribution medium, is called an ``aggregate'' if the copyright |
|
381 resulting from the compilation is not used to limit the legal rights |
|
382 of the compilation's users beyond what the individual works permit. |
|
383 When the Document is included in an aggregate, this License does not |
|
384 apply to the other works in the aggregate which are not themselves |
|
385 derivative works of the Document. |
|
386 |
|
387 If the Cover Text requirement of section 3 is applicable to these |
|
388 copies of the Document, then if the Document is less than one half of |
|
389 the entire aggregate, the Document's Cover Texts may be placed on |
|
390 covers that bracket the Document within the aggregate, or the |
|
391 electronic equivalent of covers if the Document is in electronic form. |
|
392 Otherwise they must appear on printed covers that bracket the whole |
|
393 aggregate. |
|
394 |
|
395 @item |
|
396 TRANSLATION |
|
397 |
|
398 Translation is considered a kind of modification, so you may |
|
399 distribute translations of the Document under the terms of section 4. |
|
400 Replacing Invariant Sections with translations requires special |
|
401 permission from their copyright holders, but you may include |
|
402 translations of some or all Invariant Sections in addition to the |
|
403 original versions of these Invariant Sections. You may include a |
|
404 translation of this License, and all the license notices in the |
|
405 Document, and any Warranty Disclaimers, provided that you also include |
|
406 the original English version of this License and the original versions |
|
407 of those notices and disclaimers. In case of a disagreement between |
|
408 the translation and the original version of this License or a notice |
|
409 or disclaimer, the original version will prevail. |
|
410 |
|
411 If a section in the Document is Entitled ``Acknowledgements'', |
|
412 ``Dedications'', or ``History'', the requirement (section 4) to Preserve |
|
413 its Title (section 1) will typically require changing the actual |
|
414 title. |

416 @item |
|
417 TERMINATION |
|
418 |
|
419 You may not copy, modify, sublicense, or distribute the Document except |
|
420 as expressly provided for under this License. Any other attempt to |
|
421 copy, modify, sublicense or distribute the Document is void, and will |
|
422 automatically terminate your rights under this License. However, |
|
423 parties who have received copies, or rights, from you under this |
|
424 License will not have their licenses terminated so long as such |
|
425 parties remain in full compliance. |

|
429 |
|
430 The Free Software Foundation may publish new, revised versions |
|
431 of the GNU Free Documentation License from time to time. Such new |
|
432 versions will be similar in spirit to the present version, but may |
|
433 differ in detail to address new problems or concerns. See |
|
434 @uref{http://www.gnu.org/copyleft/}. |
|
435 |
|
436 Each version of the License is given a distinguishing version number. |
|
437 If the Document specifies that a particular numbered version of this |
|
438 License ``or any later version'' applies to it, you have the option of |
|
439 following the terms and conditions either of that specified version or |
|
440 of any later version that has been published (not as a draft) by the |
|
441 Free Software Foundation. If the Document does not specify a version |
|
442 number of this License, you may choose any version ever published (not |
|
443 as a draft) by the Free Software Foundation. |
