9 </p><h2><a id="fdl-1-preamble"></a>
12 The purpose of this License is to make a manual, textbook, or other
13 functional and useful document "free" in the sense of freedom: to assure
14 everyone the effective freedom to copy and redistribute it, with or
15 without modifying it, either commercially or noncommercially.
16 Secondarily, this License preserves for the author and publisher a way to
17 get credit for their work, while not being considered responsible for
18 modifications made by others.
20 This License is a kind of "copyleft", which means that derivative works of
21 the document must themselves be free in the same sense. It complements
22 the GNU General Public License, which is a copyleft license designed for
25 We have designed this License in order to use it for manuals for free
26 software, because free software needs free documentation: a free program
27 should come with manuals providing the same freedoms that the software
28 does. But this License is not limited to software manuals; it can be used
29 for any textual work, regardless of subject matter or whether it is
30 published as a printed book. We recommend this License principally for
31 works whose purpose is instruction or reference.</p><h2><a id="fdl-1-definitions"></a>
32 1. APPLICABILITY AND DEFINITIONS
34 This License applies to any manual or other work, in any medium, that
35 contains a notice placed by the copyright holder saying it can be
36 distributed under the terms of this License. Such a notice grants a
37 world-wide, royalty-free license, unlimited in duration, to use that work
38 under the conditions stated herein. The "Document", below, refers to any
39 such manual or work. Any member of the public is a licensee, and is
40 addressed as "you". You accept the license if you copy, modify or
41 distribute the work in a way requiring permission under copyright
44 A "Modified Version" of the Document means any work containing the
45 Document or a portion of it, either copied verbatim, or with modifications
46 and/or translated into another language.
48 A "Secondary Section" is a named appendix or a front-matter section of the
49 Document that deals exclusively with the relationship of the publishers or
50 authors of the Document to the Document's overall subject (or to related
51 matters) and contains nothing that could fall directly within that overall
52 subject. (Thus, if the Document is in part a textbook of mathematics, a
53 Secondary Section may not explain any mathematics.) The relationship
54 could be a matter of historical connection with the subject or with
55 related matters, or of legal, commercial, philosophical, ethical or
56 political position regarding them.
58 The "Invariant Sections" are certain Secondary Sections whose titles are
59 designated, as being those of Invariant Sections, in the notice that says
60 that the Document is released under this License. If a section does not
61 fit the above definition of Secondary then it is not allowed to be
62 designated as Invariant. The Document may contain zero Invariant
63 Sections. If the Document does not identify any Invariant Sections then
66 The "Cover Texts" are certain short passages of text that are listed, as
67 Front-Cover Texts or Back-Cover Texts, in the notice that says that the
68 Document is released under this License. A Front-Cover Text may be at
69 most 5 words, and a Back-Cover Text may be at most 25 words.
71 A "Transparent" copy of the Document means a machine-readable copy,
72 represented in a format whose specification is available to the general
73 public, that is suitable for revising the document straightforwardly with
74 generic text editors or (for images composed of pixels) generic paint
75 programs or (for drawings) some widely available drawing editor, and that
76 is suitable for input to text formatters or for automatic translation to a
77 variety of formats suitable for input to text formatters. A copy made in
78 an otherwise Transparent file format whose markup, or absence of markup,
79 has been arranged to thwart or discourage subsequent modification by
80 readers is not Transparent. An image format is not Transparent if used
81 for any substantial amount of text. A copy that is not "Transparent" is
84 Examples of suitable formats for Transparent copies include plain ASCII
85 without markup, Texinfo input format, LaTeX input format, SGML or XML
86 using a publicly available DTD, and standard-conforming simple HTML,
87 PostScript or PDF designed for human modification. Examples of
88 transparent image formats include PNG, XCF and JPG. Opaque formats
89 include proprietary formats that can be read and edited only by
90 proprietary word processors, SGML or XML for which the DTD and/or
91 processing tools are not generally available, and the machine-generated
92 HTML, PostScript or PDF produced by some word processors for output
95 The "Title Page" means, for a printed book, the title page itself, plus
96 such following pages as are needed to hold, legibly, the material this
97 License requires to appear in the title page. For works in formats which
98 do not have any title page as such, "Title Page" means the text near the
99 most prominent appearance of the work's title, preceding the beginning of
100 the body of the text.
102 A section "Entitled XYZ" means a named subunit of the Document whose title
103 either is precisely XYZ or contains XYZ in parentheses following text that
104 translates XYZ in another language. (Here XYZ stands for a specific
105 section name mentioned below, such as "Acknowledgements", "Dedications",
106 "Endorsements", or "History".) To "Preserve the Title" of such a section
107 when you modify the Document means that it remains a section "Entitled
108 XYZ" according to this definition.
110 The Document may include Warranty Disclaimers next to the notice which
111 states that this License applies to the Document. These Warranty
112 Disclaimers are considered to be included by reference in this License,
113 but only as regards disclaiming warranties: any other implication that
114 these Warranty Disclaimers may have is void and has no effect on the
115 meaning of this License.
116 </p><h2><a id="VerbatimCopying"></a>
119 You may copy and distribute the Document in any medium, either
120 commercially or noncommercially, provided that this License, the copyright
121 notices, and the license notice saying this License applies to the
122 Document are reproduced in all copies, and that you add no other
123 conditions whatsoever to those of this License. You may not use technical
124 measures to obstruct or control the reading or further copying of the
125 copies you make or distribute. However, you may accept compensation in
126 exchange for copies. If you distribute a large enough number of copies
127 you must also follow the conditions in section 3.
129 You may also lend copies, under the same conditions stated above, and you
130 may publicly display copies.
131 </p><h2><a id="QuantityCopying"></a>
132 3. COPYING IN QUANTITY
134 If you publish printed copies (or copies in media that commonly have
135 printed covers) of the Document, numbering more than 100, and the
136 Document's license notice requires Cover Texts, you must enclose the
137 copies in covers that carry, clearly and legibly, all these Cover Texts:
138 Front-Cover Texts on the front cover, and Back-Cover Texts on the back
139 cover. Both covers must also clearly and legibly identify you as the
140 publisher of these copies. The front cover must present the full title
141 with all words of the title equally prominent and visible. You may add
142 other material on the covers in addition. Copying with changes limited to
143 the covers, as long as they preserve the title of the Document and satisfy
144 these conditions, can be treated as verbatim copying in other
147 If the required texts for either cover are too voluminous to fit legibly,
148 you should put the first ones listed (as many as fit reasonably) on the
149 actual cover, and continue the rest onto adjacent pages.
151 If you publish or distribute Opaque copies of the Document numbering more
152 than 100, you must either include a machine-readable Transparent copy
153 along with each Opaque copy, or state in or with each Opaque copy a
154 computer-network location from which the general network-using public has
155 access to download using public-standard network protocols a complete
156 Transparent copy of the Document, free of added material. If you use the
157 latter option, you must take reasonably prudent steps, when you begin
158 distribution of Opaque copies in quantity, to ensure that this Transparent
159 copy will remain thus accessible at the stated location until at least one
160 year after the last time you distribute an Opaque copy (directly or
161 through your agents or retailers) of that edition to the public.
163 It is requested, but not required, that you contact the authors of the
164 Document well before redistributing any large number of copies, to give
165 them a chance to provide you with an updated version of the
167 </p><h2><a id="Modifications"></a>
170 You may copy and distribute a Modified Version of the Document under the
171 conditions of sections 2 and 3 above, provided that you release the
172 Modified Version under precisely this License, with the Modified Version
173 filling the role of the Document, thus licensing distribution and
174 modification of the Modified Version to whoever possesses a copy of it.
175 In addition, you must do these things in the Modified Version:
176 </p><div class="orderedlist"><ol type="A"><li>
177 Use in the Title Page (and on the covers, if any) a title distinct
178 from that of the Document, and from those of previous versions (which
179 should, if there were any, be listed in the History section of the
180 Document). You may use the same title as a previous version if the
181 original publisher of that version gives permission.
183 List on 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 fewer than five),
187 unless they release you from this requirement.
189 State on the Title page the name of the publisher of the Modified
190 Version, as the publisher.
192 Preserve all the copyright notices of the Document.
194 Add an appropriate copyright notice for your modifications adjacent to
195 the other copyright notices.
197 Include, immediately after the copyright notices, a license notice
198 giving the public permission to use the Modified Version under the
199 terms of this License, in the form shown in the Addendum below.
201 Preserve in that license notice the full lists of Invariant Sections
202 and required Cover Texts given in the Document's license notice.
204 Include an unaltered copy of this License.
206 Preserve the section Entitled "History", Preserve its Title, and add
207 to it an item stating at least the title, year, new authors, and
208 publisher of the Modified Version as given on the Title Page. If
209 there is no section Entitled "History" in the Document, create one
210 stating the title, year, authors, and publisher of the Document as
211 given on its Title Page, then add an item describing the Modified
212 Version as stated in the previous sentence.
214 Preserve the network location, if any, given in the Document for
215 public access to a Transparent copy of the Document, and likewise the
216 network locations given in the Document for previous versions it was
217 based on. These may be placed in the "History" section. You may omit
218 a network location for a work that was published at least four years
219 before the Document itself, or if the original publisher of the
220 version it refers to gives permission.
222 For any section Entitled "Acknowledgements" or "Dedications", Preserve
223 the Title of the section, and preserve in the section all the
224 substance and tone of each of the contributor acknowledgements and/or
225 dedications given therein.
227 Preserve all the Invariant Sections of the Document, unaltered in
228 their text and in their titles. Section numbers or the equivalent are
229 not considered part of the section titles.
231 Delete any section Entitled "Endorsements". Such a section may not be
232 included in the Modified Version.
234 Do not retitle any existing section to be Entitled "Endorsements" or
235 to conflict in title with any Invariant Section.
237 Preserve any Warranty Disclaimers.
239 If the Modified Version includes new front-matter sections or appendices
240 that qualify as Secondary Sections and contain no material copied from the
241 Document, you may at your option designate some or all of these sections
242 as invariant. To do this, add their titles to the list of Invariant
243 Sections in the Modified Version's license notice. These titles must be
244 distinct from any other section titles.
246 You may add a section Entitled "Endorsements", provided it contains
247 nothing but endorsements of your Modified Version by various parties--for
248 example, statements of peer review or that the text has been approved by
249 an organization as the authoritative definition of a standard.
251 You may add a passage of up to five words as a Front-Cover Text, and a
252 passage of up to 25 words as a Back-Cover Text, to the end of the list of
253 Cover Texts in the Modified Version. Only one passage of Front-Cover Text
254 and one of Back-Cover Text may be added by (or through arrangements made
255 by) any one entity. If the Document already includes a cover text for the
256 same cover, previously added by you or by arrangement made by the same
257 entity you are acting on behalf of, you may not add another; but you may
258 replace the old one, on explicit permission from the previous publisher
259 that added the old one.
261 The author(s) and publisher(s) of the Document do not by this License give
262 permission to use their names for publicity for or to assert or imply
263 endorsement of any Modified Version.
264 </p><h2><a id="Combining"></a>
265 5. COMBINING DOCUMENTS
267 You may combine the Document with other documents released under this
268 License, under the terms defined in section 4 above for modified versions,
269 provided that you include in the combination all of the Invariant Sections
270 of all of the original documents, unmodified, and list them all as
271 Invariant Sections of your combined work in its license notice, and that
272 you preserve all their Warranty Disclaimers.
274 The combined work need only contain one copy of this License, and multiple
275 identical Invariant Sections may be replaced with a single copy. If there
276 are multiple Invariant Sections with the same name but different contents,
277 make the title of each such section unique by adding at the end of it, in
278 parentheses, the name of the original author or publisher of that section
279 if known, or else a unique number. Make the same adjustment to the
280 section titles in the list of Invariant Sections in the license notice of
283 In the combination, you must combine any sections Entitled "History" in
284 the various original documents, forming one section Entitled "History";
285 likewise combine any sections Entitled "Acknowledgements", and any
286 sections Entitled "Dedications". You must delete all sections Entitled
288 </p><h2><a id="Collections"></a>
289 6. COLLECTIONS OF DOCUMENTS
291 You may make a collection consisting of the Document and other documents
292 released under this License, and replace the individual copies of this
293 License in the various documents with a single copy that is included in
294 the collection, provided that you follow the rules of this License for
295 verbatim copying of each of the documents in all other respects.
297 You may extract a single document from such a collection, and distribute
298 it individually under this License, provided you insert a copy of this
299 License into the extracted document, and follow this License in all other
300 respects regarding verbatim copying of that document.
301 </p><h2><a id="Aggregation"></a>
302 7. AGGREGATION WITH INDEPENDENT WORKS
304 A compilation of the Document or its derivatives with other separate and
305 independent documents or works, in or on a volume of a storage or
306 distribution medium, is called an "aggregate" if the copyright resulting
307 from the compilation is not used to limit the legal rights of the
308 compilation's users beyond what the individual works permit. When the
309 Document is included in an aggregate, this License does not apply to the
310 other works in the aggregate which are not themselves derivative works of
313 If the Cover Text requirement of section 3 is applicable to these copies
314 of the Document, then if the Document is less than one half of the entire
315 aggregate, the Document's Cover Texts may be placed on covers that bracket
316 the Document within the aggregate, or the electronic equivalent of covers
317 if the Document is in electronic form. Otherwise they must appear on
318 printed covers that bracket the whole aggregate.
319 </p><h2><a id="Translation"></a>
322 Translation is considered a kind of modification, so you may distribute
323 translations of the Document under the terms of section 4. Replacing
324 Invariant Sections with translations requires special permission from
325 their copyright holders, but you may include translations of some or all
326 Invariant Sections in addition to the original versions of these Invariant
327 Sections. You may include a translation of this License, and all the
328 license notices in the Document, and any Warranty Disclaimers, provided
329 that you also include the original English version of this License and the
330 original versions of those notices and disclaimers. In case of a
331 disagreement between the translation and the original version of this
332 License or a notice or disclaimer, the original version will prevail.
334 If a section in the Document is Entitled "Acknowledgements",
335 "Dedications", or "History", the requirement (section 4) to Preserve its
336 Title (section 1) will typically require changing the actual title.
337 </p><h2><a id="fdl-1-termination"></a>
340 You may not copy, modify, sublicense, or distribute the Document except as
341 expressly provided for under this License. Any other attempt to copy,
342 modify, sublicense or distribute the Document is void, and will
343 automatically terminate your rights under this License. However, parties
344 who have received copies, or rights, from you under this License will not
345 have their licenses terminated so long as such parties remain in full
347 </p><h2><a id="FutureRevisions"></a>
348 10. FUTURE REVISIONS OF THIS LICENSE
350 The Free Software Foundation may publish new, revised versions of the GNU
351 Free Documentation License from time to time. Such new versions will be
352 similar in spirit to the present version, but may differ in detail to
353 address new problems or concerns. See <a class="ulink" href="http://www.gnu.org/copyleft/" target="_top">http://www.gnu.org/copyleft/</a>.
355 Each version of the License is given a distinguishing version number. If
356 the Document specifies that a particular numbered version of this License
357 "or any later version" applies to it, you have the option of following the
358 terms and conditions either of that specified version or of any later
359 version that has been published (not as a draft) by the Free Software
360 Foundation. If the Document does not specify a version number of this
361 License, you may choose any version ever published (not as a draft) by the
362 Free Software Foundation.
363 </p><h2><a id="HowToUse"></a>
364 ADDENDUM: How to use this License for your documents
366 To use this License in a document you have written, include a copy of the
367 License in the document and put the following copyright and license
368 notices just after the title page:

375 Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A
376 copy of the license is included in the section entitled "GNU Free
