GNU Free Documentation License</h2></div></div></div><p> 4 Copyright (C) 2000, 2001, 2002 Free Software Foundation, 5 <abbr class="abbrev">Inc.</abbr> 51 Franklin <abbr class="abbrev">St</abbr>, Fifth Floor, 6 Boston, <abbr class="abbrev">MA</abbr> 02110-1301 <abbr class="abbrev">USA</abbr>. Everyone is permitted to copy and 7 distribute verbatim copies of this license document, but changing it is 8 not allowed. 9 </p><h2><a id="fdl-1-preamble"></a> 10 0. PREAMBLE 11 </h2><p> 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. 19 </p><p> 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 23 free software. 24 </p><p> 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 33 </h2><p> 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 42 law. 43 </p><p> 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. 47 </p><p> 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. 57 </p><p> 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 64 there are none. 65 </p><p> 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. 70 </p><p> 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 82 called "Opaque". 83 </p><p> 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 93 purposes only. 94 </p><p> 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. 101 </p><p> 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. 109 </p><p> 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> 117 2. VERBATIM COPYING 118 </h2><p> 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. 128 </p><p> 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 133 </h2><p> 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 145 respects. 146 </p><p> 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. 150 </p><p> 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. 162 </p><p> 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 166 Document. 167 </p><h2><a id="Modifications"></a> 168 4. MODIFICATIONS 169 </h2><p> 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 class="orderedlist" type="A"><li class="listitem"> 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. 182 </li><li class="listitem"> 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. 188 </li><li class="listitem"> 189 State on the Title page the name of the publisher of the Modified 190 Version, as the publisher. 191 </li><li class="listitem"> 192 Preserve all the copyright notices of the Document. 193 </li><li class="listitem"> 194 Add an appropriate copyright notice for your modifications adjacent to 195 the other copyright notices. 196 </li><li class="listitem"> 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. 200 </li><li class="listitem"> 201 Preserve in that license notice the full lists of Invariant Sections 202 and required Cover Texts given in the Document's license notice. 203 </li><li class="listitem"> 204 Include an unaltered copy of this License. 205 </li><li class="listitem"> 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. 213 </li><li class="listitem"> 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. 221 </li><li class="listitem"> 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. 226 </li><li class="listitem"> 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. 230 </li><li class="listitem"> 231 Delete any section Entitled "Endorsements". Such a section may not be 232 included in the Modified Version. 233 </li><li class="listitem"> 234 Do not retitle any existing section to be Entitled "Endorsements" or 235 to conflict in title with any Invariant Section. 236 </li><li class="listitem"> 237 Preserve any Warranty Disclaimers. 238 </li></ol></div><p> 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. 245 </p><p> 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. 250 </p><p> 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. 260 </p><p> 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 266 </h2><p> 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. 273 </p><p> 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 281 the combined work. 282 </p><p> 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 287 "Endorsements". 288 </p><h2><a id="Collections"></a> 289 6. COLLECTIONS OF DOCUMENTS 290 </h2><p> 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. 296 </p><p> 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 303 </h2><p> 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 311 the Document. 312 </p><p> 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> 320 8. TRANSLATION 321 </h2><p> 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. 333 </p><p> 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> 338 9. TERMINATION 339 </h2><p> 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 346 compliance. 347 </p><h2><a id="FutureRevisions"></a> 348 10. FUTURE REVISIONS OF THIS LICENSE 349 </h2><p> 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>. 354 </p><p> 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 365 </h2><p> 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: 369 </p><div class="blockquote"><blockquote class="blockquote"><p> 370 Copyright (C) YEAR YOUR NAME. 371 </p><p> 372 Permission is granted to copy, distribute and/or modify this document 373 under the terms of the GNU Free Documentation License, Version 1.2 or 374 any later version published by the Free Software Foundation; with no 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 377 Documentation License". 378 </p></blockquote></div><p> 379 If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, 380 replace the "with...Texts." line with this: 381 </p><div class="blockquote"><blockquote class="blockquote"><p> 382 with the Invariant Sections being LIST THEIR TITLES, with the 383 Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. 384 </p></blockquote></div><p> 385 If you have Invariant Sections without Cover Texts, or some other 386 combination of the three, merge those two alternatives to suit the 387 situation. 388 </p><p> 389 If your document contains nontrivial examples of program code, we 390 recommend releasing these examples in parallel under your choice of free 391 software license, such as the GNU General Public License, to permit their 392 use in free software. 393 </p></div><div class="navfooter"><hr /><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="appendix_gpl.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="spine.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="bk01ix01.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Appendix D. 394 <acronym class="acronym">GNU</acronym> General Public License version 3 395 </td><td width="20%" align="center"><a accesskey="h" href="../spine.html">Home</a></td><td width="40%" align="right" valign="top"> Index</td></tr></table></div></body></html> 396
