|
---|
31 |
|
---|
32 | Everyone is permitted to copy and distribute verbatim copies of
|
---|
33 | this license document, but changing it is not allowed.
|
---|
34 |
|
---|
35 | 0. PREAMBLE
|
---|
36 |
|
---|
37 | The purpose of this License is to make a manual, textbook, or other
|
---|
38 | written document "free" in the sense of freedom: to assure everyone the
|
---|
39 | effective freedom to copy and redistribute it, with or without
|
---|
40 | modifying it, either commercially or noncommercially. Secondarily,
|
---|
41 | this License preserves for the author and publisher a way to get credit
|
---|
42 | for their work, while not being considered responsible for
|
---|
43 | modifications made by others.
|
---|
44 |
|
---|
45 | This License is a kind of "copyleft", which means that derivative
|
---|
46 | works of the document must themselves be free in the same sense. It
|
---|
47 | complements the GNU General Public License, which is a copyleft license
|
---|
48 | designed for free software.
|
---|
49 |
|
---|
50 | We have designed this License in order to use it for manuals for free
|
---|
51 | software, because free software needs free documentation: a free
|
---|
52 | program should come with manuals providing the same freedoms that the
|
---|
53 | software does. But this License is not limited to software manuals; it
|
---|
54 | can be used for any textual work, regardless of subject matter or
|
---|
55 | whether it is published as a printed book. We recommend this License
|
---|
56 | principally for works whose purpose is instruction or reference.
|
---|
57 |
|
---|
58 | 1. APPLICABILITY AND DEFINITIONS
|
---|
59 |
|
---|
60 | This License applies to any manual or other work that contains a
|
---|
61 | notice placed by the copyright holder saying it can be distributed
|
---|
62 | under the terms of this License. The "Document", below, refers to any
|
---|
63 | such manual or work. Any member of the public is a licensee, and is
|
---|
64 | addressed as "you".
|
---|
65 |
|
---|
66 | A "Modified Version" of the Document means any work containing the
|
---|
67 | Document or a portion of it, either copied verbatim, or with
|
---|
68 | modifications and/or translated into another language.
|
---|
69 |
|
---|
70 | A "Secondary Section" is a named appendix or a front-matter section
|
---|
71 | of the Document that deals exclusively with the relationship of the
|
---|
72 | publishers or authors of the Document to the Document's overall subject
|
---|
73 | (or to related matters) and contains nothing that could fall directly
|
---|
74 | within that overall subject. (For example, if the Document is in part a
|
---|
75 | textbook of mathematics, a Secondary Section may not explain any
|
---|
76 | mathematics.) The relationship could be a matter of historical
|
---|
77 | connection with the subject or with related matters, or of legal,
|
---|
78 | commercial, philosophical, ethical or political position regarding them.
|
---|
79 |
|
---|
80 | The "Invariant Sections" are certain Secondary Sections whose titles
|
---|
81 | are designated, as being those of Invariant Sections, in the notice
|
---|
82 | that says that the Document is released under this License.
|
---|
83 |
|
---|
84 | The "Cover Texts" are certain short passages of text that are listed,
|
---|
85 | as Front-Cover Texts or Back-Cover Texts, in the notice that says that
|
---|
86 | the Document is released under this License.
|
---|
87 |
|
---|
88 | A "Transparent" copy of the Document means a machine-readable copy,
|
---|
89 | represented in a format whose specification is available to the general
|
---|
90 | public, whose contents can be viewed and edited directly and
|
---|
91 | straightforwardly with generic text editors or (for images composed of
|
---|
92 | pixels) generic paint programs or (for drawings) some widely available
|
---|
93 | drawing editor, and that is suitable for input to text formatters or
|
---|
94 | for automatic translation to a variety of formats suitable for input to
|
---|
95 | text formatters. A copy made in an otherwise Transparent file format
|
---|
96 | whose markup has been designed to thwart or discourage subsequent
|
---|
97 | modification by readers is not Transparent. A copy that is not
|
---|
98 | "Transparent" is called "Opaque".
|
---|
99 |
|
---|
100 | Examples of suitable formats for Transparent copies include plain
|
---|
101 | ASCII without markup, Texinfo input format, LaTeX input format, SGML or
|
---|
102 | XML using a publicly available DTD, and standard-conforming simple HTML
|
---|
103 | designed for human modification. Opaque formats include PostScript,
|
---|
104 | PDF, proprietary formats that can be read and edited only by
|
---|
105 | proprietary word processors, SGML or XML for which the DTD and/or
|
---|
106 | processing tools are not generally available, and the machine-generated
|
---|
107 | HTML produced by some word processors for output purposes only.
|
---|
108 |
|
---|
109 | The "Title Page" means, for a printed book, the title page itself,
|
---|
110 | plus such following pages as are needed to hold, legibly, the material
|
---|
111 | this License requires to appear in the title page. For works in
|
---|
112 | formats which do not have any title page as such, "Title Page" means
|
---|
113 | the text near the most prominent appearance of the work's title,
|
---|
114 | preceding the beginning of the body of the text.
|
---|
115 |
|
---|
116 | 2. VERBATIM COPYING
|
---|
117 |
|
---|
118 | You may copy and distribute the Document in any medium, either
|
---|
119 | commercially or noncommercially, provided that this License, the
|
---|
120 | copyright notices, and the license notice saying this License applies
|
---|
121 | to the Document are reproduced in all copies, and that you add no other
|
---|
122 | conditions whatsoever to those of this License. You may not use
|
---|
123 | technical measures to obstruct or control the reading or further
|
---|
124 | copying of the copies you make or distribute. However, you may accept
|
---|
125 | compensation in exchange for copies. If you distribute a large enough
|
---|
126 | number of copies you must also follow the conditions in section 3.
|
---|
127 |
|
---|
128 | You may also lend copies, under the same conditions stated above, and
|
---|
129 | you may publicly display copies.
|
---|
130 |
|
---|
131 | 3. COPYING IN QUANTITY
|
---|
132 |
|
---|
133 | If you publish printed copies of the Document numbering more than
|
---|
134 | 100, and the Document's license notice requires Cover Texts, you must
|
---|
135 | enclose the copies in covers that carry, clearly and legibly, all these
|
---|
136 | Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts
|
---|
137 | on the back cover. Both covers must also clearly and legibly identify
|
---|
138 | you as the publisher of these copies. The front cover must present the
|
---|
139 | full title with all words of the title equally prominent and visible.
|
---|
140 | You may add other material on the covers in addition. Copying with
|
---|
141 | changes limited to the covers, as long as they preserve the title of
|
---|
142 | the Document and satisfy these conditions, can be treated as verbatim
|
---|
143 | copying in other respects.
|
---|
144 |
|
---|
145 | If the required texts for either cover are too voluminous to fit
|
---|
146 | legibly, you should put the first ones listed (as many as fit
|
---|
147 | reasonably) on the actual cover, and continue the rest onto adjacent
|
---|
148 | pages.
|
---|
149 |
|
---|
150 | If you publish or distribute Opaque copies of the Document numbering
|
---|
151 | more than 100, you must either include a machine-readable Transparent
|
---|
152 | copy along with each Opaque copy, or state in or with each Opaque copy
|
---|
153 | a publicly-accessible computer-network location containing a complete
|
---|
154 | Transparent copy of the Document, free of added material, which the
|
---|
155 | general network-using public has access to download anonymously at no
|
---|
156 | charge using public-standard network protocols. If you use the latter
|
---|
157 | option, you must take reasonably prudent steps, when you begin
|
---|
158 | distribution of Opaque copies in quantity, to ensure that this
|
---|
159 | Transparent copy will remain thus accessible at the stated location
|
---|
160 | until at least one year after the last time you distribute an Opaque
|
---|
161 | copy (directly or through your agents or retailers) of that edition to
|
---|
162 | the public.
|
---|
163 |
|
---|
164 | It is requested, but not required, that you contact the authors of
|
---|
165 | the Document well before redistributing any large number of copies, to
|
---|
166 | give them a chance to provide you with an updated version of the
|
---|
167 | Document.
|
---|
168 |
|
---|
169 | 4. MODIFICATIONS
|
---|
170 |
|
---|
171 | You may copy and distribute a Modified Version of the Document under
|
---|
172 | the conditions of sections 2 and 3 above, provided that you release the
|
---|
173 | Modified Version under precisely this License, with the Modified
|
---|
174 | Version filling the role of the Document, thus licensing distribution
|
---|
175 | and modification of the Modified Version to whoever possesses a copy of
|
---|
176 | it. In addition, you must do these things in the Modified Version:
|
---|
177 |
|
---|
178 | A. Use in the Title Page (and on the covers, if any) a title distinct
|
---|
179 | from that of the Document, and from those of previous versions
|
---|
180 | (which should, if there were any, be listed in the History section
|
---|
181 | of the Document). You may use the same title as a previous version
|
---|
182 | if the original publisher of that version gives permission. B. List on
|
---|
183 | the Title Page, as authors, one or more persons or entities
|
---|
184 | responsible for authorship of the modifications in the Modified
|
---|
185 | Version, together with at least five of the principal authors of the
|
---|
186 | Document (all of its principal authors, if it has less than five). C.
|
---|
187 | State on the Title page the name of the publisher of the Modified
|
---|
188 | Version, as the publisher. D. Preserve all the copyright notices of
|
---|
189 | the Document. E. Add an appropriate copyright notice for your
|
---|
190 | modifications adjacent to the other copyright notices. F. Include,
|
---|
191 | immediately after the copyright notices, a license notice giving the
|
---|
192 | public permission to use the Modified Version under the terms of
|
---|
193 | this License, in the form shown in the Addendum below. G. Preserve in
|
---|
194 | that license notice the full lists of Invariant Sections and
|
---|
195 | required Cover Texts given in the Document's license notice. H.
|
---|
196 | Include an unaltered copy of this License. I. Preserve the section
|
---|
197 | entitled "History", and its title, and add to it an item stating at
|
---|
198 | least the title, year, new authors, and publisher of the Modified
|
---|
199 | Version as given on the Title Page. If there is no section entitled
|
---|
200 | "History" in the Document, create one stating the title, year,
|
---|
201 | authors, and publisher of the Document as given on its Title Page,
|
---|
202 | then add an item describing the Modified Version as stated in the
|
---|
203 | previous sentence. J. Preserve the network location, if any, given in
|
---|
204 | the Document for public access to a Transparent copy of the
|
---|
205 | Document, and likewise the network locations given in the Document
|
---|
206 | for previous versions it was based on. These may be placed in the
|
---|
207 | "History" section. You may omit a network location for a work that
|
---|
208 | was published at least four years before the Document itself, or if
|
---|
209 | the original publisher of the version it refers to gives permission.
|
---|
210 | K. In any section entitled "Acknowledgements" or "Dedications",
|
---|
211 | preserve the section's title, and preserve in the section all the
|
---|
212 | substance and tone of each of the contributor acknowledgements
|
---|
213 | and/or dedications given therein. L. Preserve all the Invariant
|
---|
214 | Sections of the Document, unaltered in their text and in their
|
---|
215 | titles. Section numbers or the equivalent are not considered part
|
---|
216 | of the section titles. M. Delete any section entitled "Endorsements".
|
---|
217 | Such a section may not be included in the Modified Version. N. Do
|
---|
218 | not retitle any existing section as "Endorsements" or to conflict in
|
---|
219 | title with any Invariant Section.
|
---|
220 |
|
---|
221 | If the Modified Version includes new front-matter sections or
|
---|
222 | appendices that qualify as Secondary Sections and contain no material
|
---|
223 | copied from the Document, you may at your option designate some or all
|
---|
224 | of these sections as invariant. To do this, add their titles to the
|
---|
225 | list of Invariant Sections in the Modified Version's license notice.
|
---|
226 | These titles must be distinct from any other section titles.
|
---|
227 |
|
---|
228 | You may add a section entitled "Endorsements", provided it contains
|
---|
229 | nothing but endorsements of your Modified Version by various
|
---|
230 | parties-for example, statements of peer review or that the text has
|
---|
231 | been approved by an organization as the authoritative definition of a
|
---|
232 | standard.
|
---|
233 |
|
---|
234 | You may add a passage of up to five words as a Front-Cover Text, and
|
---|
235 | a passage of up to 25 words as a Back-Cover Text, to the end of the list
|
---|
236 | of Cover Texts in the Modified Version. Only one passage of
|
---|
237 | Front-Cover Text and one of Back-Cover Text may be added by (or through
|
---|
238 | arrangements made by) any one entity. If the Document already includes
|
---|
239 | a cover text for the same cover, previously added by you or by
|
---|
240 | arrangement made by the same entity you are acting on behalf of, you
|
---|
241 | may not add another; but you may replace the old one, on explicit
|
---|
242 | permission from the previous publisher that added the old one.
|
---|
243 |
|
---|
244 | The author(s) and publisher(s) of the Document do not by this License
|
---|
245 | give permission to use their names for publicity for or to assert or
|
---|
246 | imply endorsement of any Modified Version.
|
---|
247 |
|
---|
248 | 5. COMBINING DOCUMENTS
|
---|
249 |
|
---|
250 | You may combine the Document with other documents released under this
|
---|
251 | License, under the terms defined in section 4 above for modified
|
---|
252 | versions, provided that you include in the combination all of the
|
---|
253 | Invariant Sections of all of the original documents, unmodified, and
|
---|
254 | list them all as Invariant Sections of your combined work in its
|
---|
255 | license notice.
|
---|
256 |
|
---|
257 | The combined work need only contain one copy of this License, and
|
---|
258 | multiple identical Invariant Sections may be replaced with a single
|
---|
259 | copy. If there are multiple Invariant Sections with the same name but
|
---|
260 | different contents, make the title of each such section unique by
|
---|
261 | adding at the end of it, in parentheses, the name of the original
|
---|
262 | author or publisher of that section if known, or else a unique number.
|
---|
263 | Make the same adjustment to the section titles in the list of Invariant
|
---|
264 | Sections in the license notice of the combined work.
|
---|
265 |
|
---|
266 | In the combination, you must combine any sections entitled "History"
|
---|
267 | in the various original documents, forming one section entitled
|
---|
268 | "History"; likewise combine any sections entitled "Acknowledgements",
|
---|
269 | and any sections entitled "Dedications". You must delete all sections
|
---|
270 | entitled "Endorsements."
|
---|
271 |
|
---|
272 | 6. COLLECTIONS OF DOCUMENTS
|
---|
273 |
|
---|
274 | You may make a collection consisting of the Document and other
|
---|
275 | documents released under this License, and replace the individual
|
---|
276 | copies of this License in the various documents with a single copy that
|
---|
277 | is included in the collection, provided that you follow the rules of
|
---|
278 | this License for verbatim copying of each of the documents in all other
|
---|
279 | respects.
|
---|
280 |
|
---|
281 | You may extract a single document from such a collection, and
|
---|
282 | distribute it individually under this License, provided you insert a
|
---|
283 | copy of this License into the extracted document, and follow this
|
---|
284 | License in all other respects regarding verbatim copying of that
|
---|
285 | document.
|
---|
286 |
|
---|
287 | 7. AGGREGATION WITH INDEPENDENT WORKS
|
---|
288 |
|
---|
289 | A compilation of the Document or its derivatives with other separate
|
---|
290 | and independent documents or works, in or on a volume of a storage or
|
---|
291 | distribution medium, does not as a whole count as a Modified Version of
|
---|
292 | the Document, provided no compilation copyright is claimed for the
|
---|
293 | compilation. Such a compilation is called an "aggregate", and this
|
---|
294 | License does not apply to the other self-contained works thus compiled
|
---|
295 | with the Document, on account of their being thus compiled, if they are
|
---|
296 | not themselves derivative works of the Document.
|
---|
297 |
|
---|
298 | If the Cover Text requirement of section 3 is applicable to these
|
---|
299 | copies of the Document, then if the Document is less than one quarter
|
---|
300 | of the entire aggregate, the Document's Cover Texts may be placed on
|
---|
301 | covers that surround only the Document within the aggregate. Otherwise
|
---|
302 | they must appear on covers around the whole aggregate.
|
---|
303 |
|
---|
304 | 8. TRANSLATION
|
---|
305 |
|
---|
306 | Translation is considered a kind of modification, so you may
|
---|
307 | distribute translations of the Document under the terms of section 4.
|
---|
308 | Replacing Invariant Sections with translations requires special
|
---|
309 | permission from their copyright holders, but you may include
|
---|
310 | translations of some or all Invariant Sections in addition to the
|
---|
311 | original versions of these Invariant Sections. You may include a
|
---|
312 | translation of this License provided that you also include the original
|
---|
313 | English version of this License. In case of a disagreement between the
|
---|
314 | translation and the original English version of this License, the
|
---|
315 | original English version will prevail.
|
---|
316 |
|
---|
317 | 9. TERMINATION
|
---|
318 |
|
---|
319 | You may not copy, modify, sublicense, or distribute the Document
|
---|
320 | except as expressly provided for under this License. Any other attempt
|
---|
321 | to copy, modify, sublicense or distribute the Document is void, and will
|
---|
322 | automatically terminate your rights under this License. However,
|
---|
323 | parties who have received copies, or rights, from you under this
|
---|
324 | License will not have their licenses terminated so long as such parties
|
---|
325 | remain in full compliance.
|
---|
326 |
|
---|
327 | 10. FUTURE REVISIONS OF THIS LICENSE
|
---|
328 |
|
---|
329 | The Free Software Foundation may publish new, revised versions of
|
---|
330 | the GNU Free Documentation License from time to time. Such new
|
---|
331 | versions will be similar in spirit to the present version, but may
|
---|
332 | differ in detail to address new problems or concerns. See
|
---|
333 | http://www.gnu.org/copyleft/.
|
---|
334 |
|
---|
335 | Each version of the License is given a distinguishing version number.
|
---|
336 | If the Document specifies that a particular numbered version of this
|
---|
337 | License "or any later version" applies to it, you have the option of
|
---|
338 | following the terms and conditions either of that specified version or
|
---|
339 | of any later version that has been published (not as a draft) by the
|
---|
340 | Free Software Foundation. If the Document does not specify a version
|
---|
341 | number of this License, you may choose any version ever published (not
|
---|
342 | as a draft) by the Free Software Foundation.
|
---|
343 |
