PREAMBLE 17 </bridgehead> 18 <simpara> 19 The purpose of this License is to make a manual, textbook, or other 20 functional and useful document ���free��� in the sense of freedom: 21 to assure everyone the effective freedom to copy and redistribute it, with 22 or without modifying it, either commercially or 23 noncommercially. Secondarily, this License preserves for the author and 24 publisher a way to get credit for their work, while not being considered 25 responsible for modifications made by others. 26 </simpara> 27 <simpara> 28 This License is a kind of ���copyleft���, which means that 29 derivative works of the document must themselves be free in the same 30 sense. It complements the GNU General Public License, which is a copyleft 31 license designed for free software. 32 </simpara> 33 <simpara> 34 We have designed this License in order to use it for manuals for free 35 software, because free software needs free documentation: a free program 36 should come with manuals providing the same freedoms that the software 37 does. But this License is not limited to software manuals; it can be used 38 for any textual work, regardless of subject matter or whether it is 39 published as a printed book. We recommend this License principally for 40 works whose purpose is instruction or reference. 41 </simpara> 42 <bridgehead xml:id="fdl-1-section1" renderas="sect2"> 43 1. APPLICABILITY AND DEFINITIONS 44 </bridgehead> 45 <simpara> 46 This License applies to any manual or other work, in any medium, that 47 contains a notice placed by the copyright holder saying it can be 48 distributed under the terms of this License. Such a notice grants a 49 world-wide, royalty-free license, unlimited in duration, to use that work 50 under the conditions stated herein. The ���Document���, below, 51 refers to any such manual or work. Any member of the public is a licensee, 52 and is addressed as ���you���. You accept the license if you copy, 53 modify or distribute the work in a way requiring permission under 54 copyright law. 55 </simpara> 56 <simpara> 57 A ���Modified Version��� of the Document means any work containing 58 the Document or a portion of it, either copied verbatim, or with 59 modifications and/or translated into another language. 60 </simpara> 61 <simpara> 62 A ���Secondary Section��� is a named appendix or a front-matter 63 section of the Document that deals exclusively with the relationship of 64 the publishers or authors of the Document to the Document���s overall 65 subject (or to related matters) and contains nothing that could fall 66 directly within that overall subject. (Thus, if the Document is in part a 67 textbook of mathematics, a Secondary Section may not explain any 68 mathematics.) The relationship could be a matter of historical connection 69 with the subject or with related matters, or of legal, commercial, 70 philosophical, ethical or political position regarding them. 71 </simpara> 72 <simpara> 73 The ���Invariant Sections��� are certain Secondary Sections whose 74 titles are designated, as being those of Invariant Sections, in the notice 75 that says that the Document is released under this License. If a section 76 does not fit the above definition of Secondary then it is not allowed to 77 be designated as Invariant. The Document may contain zero Invariant 78 Sections. If the Document does not identify any Invariant Sections then 79 there are none. 80 </simpara> 81 <simpara> 82 The ���Cover Texts��� are certain short passages of text that are 83 listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says 84 that the Document is released under this License. A Front-Cover Text may 85 be at most 5 words, and a Back-Cover Text may be at most 25 words. 86 </simpara> 87 <simpara> 88 A ���Transparent��� copy of the Document means a machine-readable 89 copy, represented in a format whose specification is available to the 90 general public, that is suitable for revising the document 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 for 94 automatic translation to a variety of formats suitable for input to text 95 formatters. A copy made in an otherwise Transparent file format whose 96 markup, or absence of markup, has been arranged to thwart or discourage 97 subsequent modification by readers is not Transparent. An image format is 98 not Transparent if used for any substantial amount of text. A copy that is 99 not ���Transparent��� is called ���Opaque���. 100 </simpara> 101 <simpara> 102 Examples of suitable formats for Transparent copies include plain ASCII 103 without markup, Texinfo input format, LaTeX input format, SGML or XML 104 using a publicly available DTD, and standard-conforming simple HTML, 105 PostScript or PDF designed for human modification. Examples of transparent 106 image formats include PNG, XCF and JPG. Opaque formats include proprietary 107 formats that can be read and edited only by proprietary word processors, 108 SGML or XML for which the DTD and/or processing tools are not generally 109 available, and the machine-generated HTML, PostScript or PDF produced by 110 some word processors for output purposes only. 111 </simpara> 112 <simpara> 113 The ���Title Page��� means, for a printed book, the title page 114 itself, plus such following pages as are needed to hold, legibly, the 115 material this License requires to appear in the title page. For works in 116 formats which do not have any title page as such, ���Title Page��� 117 means the text near the most prominent appearance of the work���s 118 title, preceding the beginning of the body of the text. 119 </simpara> 120 <simpara> 121 The ���publisher��� means any person or entity that distributes 122 copies of the Document to the public. 123 </simpara> 124 <simpara> 125 A section ���Entitled XYZ��� means a named subunit of the Document 126 whose title either is precisely XYZ or contains XYZ in parentheses 127 following text that translates XYZ in another language. (Here XYZ stands 128 for a specific section name mentioned below, such as 129 ���Acknowledgements���, ���Dedications���, 130 ���Endorsements���, or ���History���.) To ���Preserve 131 the Title��� of such a section when you modify the Document means that 132 it remains a section ���Entitled XYZ��� according to this 133 definition. 134 </simpara> 135 <simpara> 136 The Document may include Warranty Disclaimers next to the notice which 137 states that this License applies to the Document. These Warranty 138 Disclaimers are considered to be included by reference in this License, 139 but only as regards disclaiming warranties: any other implication that 140 these Warranty Disclaimers may have is void and has no effect on the 141 meaning of this License. 142 </simpara> 143 <bridgehead xml:id="fdl-1-section2" renderas="sect2"> 144 2. VERBATIM COPYING 145 </bridgehead> 146 <simpara> 147 You may copy and distribute the Document in any medium, either 148 commercially or noncommercially, provided that this License, the copyright 149 notices, and the license notice saying this License applies to the 150 Document are reproduced in all copies, and that you add no other 151 conditions whatsoever to those of this License. You may not use technical 152 measures to obstruct or control the reading or further copying of the 153 copies you make or distribute. However, you may accept compensation in 154 exchange for copies. If you distribute a large enough number of copies you 155 must also follow the conditions in section 3. 156 </simpara> 157 <simpara> 158 You may also lend copies, under the same conditions stated above, and you 159 may publicly display copies. 160 </simpara> 161 <bridgehead xml:id="fdl-1-section3" renderas="sect2"> 162 3. COPYING IN QUANTITY 163 </bridgehead> 164 <simpara> 165 If you publish printed copies (or copies in media that commonly have 166 printed covers) of the Document, numbering more than 100, and the 167 Document���s license notice requires Cover Texts, you must enclose 168 the copies in covers that carry, clearly and legibly, all these Cover 169 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the 170 back cover. Both covers must also clearly and legibly identify you as the 171 publisher of these copies. The front cover must present the full title 172 with all words of the title equally prominent and visible. You may add 173 other material on the covers in addition. Copying with changes limited to 174 the covers, as long as they preserve the title of the Document and satisfy 175 these conditions, can be treated as verbatim copying in other respects. 176 </simpara> 177 <simpara> 178 If the required texts for either cover are too voluminous to fit legibly, 179 you should put the first ones listed (as many as fit reasonably) on the 180 actual cover, and continue the rest onto adjacent pages. 181 </simpara> 182 <simpara> 183 If you publish or distribute Opaque copies of the Document numbering more 184 than 100, you must either include a machine-readable Transparent copy 185 along with each Opaque copy, or state in or with each Opaque copy a 186 computer-network location from which the general network-using public has 187 access to download using public-standard network protocols a complete 188 Transparent copy of the Document, free of added material. If you use the 189 latter option, you must take reasonably prudent steps, when you begin 190 distribution of Opaque copies in quantity, to ensure that this Transparent 191 copy will remain thus accessible at the stated location until at least one 192 year after the last time you distribute an Opaque copy (directly or 193 through your agents or retailers) of that edition to the public. 194 </simpara> 195 <simpara> 196 It is requested, but not required, that you contact the authors of the 197 Document well before redistributing any large number of copies, to give 198 them a chance to provide you with an updated version of the Document. 199 </simpara> 200 <bridgehead xml:id="fdl-1-section4" renderas="sect2"> 201 4. MODIFICATIONS 202 </bridgehead> 203 <simpara> 204 You may copy and distribute a Modified Version of the Document under the 205 conditions of sections 2 and 3 above, provided that you release the 206 Modified Version under precisely this License, with the Modified Version 207 filling the role of the Document, thus licensing distribution and 208 modification of the Modified Version to whoever possesses a copy of it. In 209 addition, you must do these things in the Modified Version: 210 </simpara> 211 <orderedlist numeration="upperalpha"> 212 <listitem> 213 <simpara> 214 Use in the Title Page (and on the covers, if any) a title distinct 215 from that of the Document, and from those of previous versions (which 216 should, if there were any, be listed in the History section of the 217 Document). You may use the same title as a previous version if the 218 original publisher of that version gives permission. 219 </simpara> 220 </listitem> 221 <listitem> 222 <simpara> 223 List on the Title Page, as authors, one or more persons or entities 224 responsible for authorship of the modifications in the Modified 225 Version, together with at least five of the principal authors of the 226 Document (all of its principal authors, if it has fewer than five), 227 unless they release you from this requirement. 228 </simpara> 229 </listitem> 230 <listitem> 231 <simpara> 232 State on the Title page the name of the publisher of the Modified 233 Version, as the publisher. 234 </simpara> 235 </listitem> 236 <listitem> 237 <simpara> 238 Preserve all the copyright notices of the Document. 239 </simpara> 240 </listitem> 241 <listitem> 242 <simpara> 243 Add an appropriate copyright notice for your modifications adjacent to 244 the other copyright notices. 245 </simpara> 246 </listitem> 247 <listitem> 248 <simpara> 249 Include, immediately after the copyright notices, a license notice 250 giving the public permission to use the Modified Version under the 251 terms of this License, in the form shown in the Addendum below. 252 </simpara> 253 </listitem> 254 <listitem> 255 <simpara> 256 Preserve in that license notice the full lists of Invariant Sections 257 and required Cover Texts given in the Document���s license 258 notice. 259 </simpara> 260 </listitem> 261 <listitem> 262 <simpara> 263 Include an unaltered copy of this License. 264 </simpara> 265 </listitem> 266 <listitem> 267 <simpara> 268 Preserve the section Entitled ���History���, Preserve its 269 Title, and add to it an item stating at least the title, year, new 270 authors, and publisher of the Modified Version as given on the Title 271 Page. If there is no section Entitled ���History��� in the 272 Document, create one stating the title, year, authors, and publisher 273 of the Document as given on its Title Page, then add an item 274 describing the Modified Version as stated in the previous sentence. 275 </simpara> 276 </listitem> 277 <listitem> 278 <simpara> 279 Preserve the network location, if any, given in the Document for 280 public access to a Transparent copy of the Document, and likewise the 281 network locations given in the Document for previous versions it was 282 based on. These may be placed in the ���History��� 283 section. You may omit a network location for a work that was published 284 at least four years before the Document itself, or if the original 285 publisher of the version it refers to gives permission. 286 </simpara> 287 </listitem> 288 <listitem> 289 <simpara> 290 For any section Entitled ���Acknowledgements��� or 291 ���Dedications���, Preserve the Title of the section, and 292 preserve in the section all the substance and tone of each of the 293 contributor acknowledgements and/or dedications given therein. 294 </simpara> 295 </listitem> 296 <listitem> 297 <simpara> 298 Preserve all the Invariant Sections of the Document, unaltered in 299 their text and in their titles. Section numbers or the equivalent are 300 not considered part of the section titles. 301 </simpara> 302 </listitem> 303 <listitem> 304 <simpara> 305 Delete any section Entitled ���Endorsements���. Such a section 306 may not be included in the Modified Version. 307 </simpara> 308 </listitem> 309 <listitem> 310 <simpara> 311 Do not retitle any existing section to be Entitled 312 ���Endorsements��� or to conflict in title with any Invariant 313 Section. 314 </simpara> 315 </listitem> 316 <listitem> 317 <simpara> 318 Preserve any Warranty Disclaimers. 319 </simpara> 320 </listitem> 321 </orderedlist> 322 <simpara> 323 If the Modified Version includes new front-matter sections or appendices 324 that qualify as Secondary Sections and contain no material copied from the 325 Document, you may at your option designate some or all of these sections 326 as invariant. To do this, add their titles to the list of Invariant 327 Sections in the Modified Version���s license notice. These titles 328 must be distinct from any other section titles. 329 </simpara> 330 <simpara> 331 You may add a section Entitled ���Endorsements���, provided it 332 contains nothing but endorsements of your Modified Version by various 333 parties ��� for example, statements of peer review or that the text 334 has been approved by an organization as the authoritative definition of a 335 standard. 336 </simpara> 337 <simpara> 338 You may add a passage of up to five words as a Front-Cover Text, and a 339 passage of up to 25 words as a Back-Cover Text, to the end of the list of 340 Cover Texts in the Modified Version. Only one passage of Front-Cover Text 341 and one of Back-Cover Text may be added by (or through arrangements made 342 by) any one entity. If the Document already includes a cover text for the 343 same cover, previously added by you or by arrangement made by the same 344 entity you are acting on behalf of, you may not add another; but you may 345 replace the old one, on explicit permission from the previous publisher 346 that added the old one. 347 </simpara> 348 <simpara> 349 The author(s) and publisher(s) of the Document do not by this License give 350 permission to use their names for publicity for or to assert or imply 351 endorsement of any Modified Version. 352 </simpara> 353 <bridgehead xml:id="fdl-1-section5" renderas="sect2"> 354 5. COMBINING DOCUMENTS 355 </bridgehead> 356 <simpara> 357 You may combine the Document with other documents released under this 358 License, under the terms defined in section 4 above for modified versions, 359 provided that you include in the combination all of the Invariant Sections 360 of all of the original documents, unmodified, and list them all as 361 Invariant Sections of your combined work in its license notice, and that 362 you preserve all their Warranty Disclaimers. 363 </simpara> 364 <simpara> 365 The combined work need only contain one copy of this License, and multiple 366 identical Invariant Sections may be replaced with a single copy. If there 367 are multiple Invariant Sections with the same name but different contents, 368 make the title of each such section unique by adding at the end of it, in 369 parentheses, the name of the original author or publisher of that section 370 if known, or else a unique number. Make the same adjustment to the section 371 titles in the list of Invariant Sections in the license notice of the 372 combined work. 373 </simpara> 374 <simpara> 375 In the combination, you must combine any sections Entitled 376 ���History��� in the various original documents, forming one 377 section Entitled ���History���; likewise combine any sections 378 Entitled ���Acknowledgements���, and any sections Entitled 379 ���Dedications���. You must delete all sections Entitled 380 ���Endorsements���. 381 </simpara> 382 <bridgehead xml:id="fdl-1-section6" renderas="sect2"> 383 6. COLLECTIONS OF DOCUMENTS 384 </bridgehead> 385 <simpara> 386 You may make a collection consisting of the Document and other documents 387 released under this License, and replace the individual copies of this 388 License in the various documents with a single copy that is included in 389 the collection, provided that you follow the rules of this License for 390 verbatim copying of each of the documents in all other respects. 391 </simpara> 392 <simpara> 393 You may extract a single document from such a collection, and distribute 394 it individually under this License, provided you insert a copy of this 395 License into the extracted document, and follow this License in all other 396 respects regarding verbatim copying of that document. 397 </simpara> 398 <bridgehead xml:id="fdl-1-section7" renderas="sect2"> 399 7. AGGREGATION WITH INDEPENDENT WORKS 400 </bridgehead> 401 <simpara> 402 A compilation of the Document or its derivatives with other separate and 403 independent documents or works, in or on a volume of a storage or 404 distribution medium, is called an ���aggregate��� if the copyright 405 resulting from the compilation is not used to limit the legal rights of 406 the compilation���s users beyond what the individual works 407 permit. When the Document is included in an aggregate, this License does 408 not apply to the other works in the aggregate which are not themselves 409 derivative works of the Document. 410 </simpara> 411 <simpara> 412 If the Cover Text requirement of section 3 is applicable to these copies 413 of the Document, then if the Document is less than one half of the entire 414 aggregate, the Document���s Cover Texts may be placed on covers that 415 bracket the Document within the aggregate, or the electronic equivalent of 416 covers if the Document is in electronic form. Otherwise they must appear 417 on printed covers that bracket the whole aggregate. 418 </simpara> 419 <bridgehead xml:id="fdl-1-section8" renderas="sect2"> 420 8. TRANSLATION 421 </bridgehead> 422 <simpara> 423 Translation is considered a kind of modification, so you may distribute 424 translations of the Document under the terms of section 4. Replacing 425 Invariant Sections with translations requires special permission from 426 their copyright holders, but you may include translations of some or all 427 Invariant Sections in addition to the original versions of these Invariant 428 Sections. You may include a translation of this License, and all the 429 license notices in the Document, and any Warranty Disclaimers, provided 430 that you also include the original English version of this License and the 431 original versions of those notices and disclaimers. In case of a 432 disagreement between the translation and the original version of this 433 License or a notice or disclaimer, the original version will prevail. 434 </simpara> 435 <simpara> 436 If a section in the Document is Entitled ���Acknowledgements���, 437 ���Dedications���, or ���History���, the requirement 438 (section 4) to Preserve its Title (section 1) will typically require 439 changing the actual title. 440 </simpara> 441 <bridgehead xml:id="fdl-1-section9" renderas="sect2"> 442 9. TERMINATION 443 </bridgehead> 444 <simpara> 445 You may not copy, modify, sublicense, or distribute the Document except as 446 expressly provided under this License. Any attempt otherwise to copy, 447 modify, sublicense, or distribute it is void, and will automatically 448 terminate your rights under this License. 449 </simpara> 450 <simpara> 451 However, if you cease all violation of this License, then your license 452 from a particular copyright holder is reinstated (a) provisionally, unless 453 and until the copyright holder explicitly and finally terminates your 454 license, and (b) permanently, if the copyright holder fails to notify you 455 of the violation by some reasonable means prior to 60 days after the 456 cessation. 457 </simpara> 458 <simpara> 459 Moreover, your license from a particular copyright holder is reinstated 460 permanently if the copyright holder notifies you of the violation by some 461 reasonable means, this is the first time you have received notice of 462 violation of this License (for any work) from that copyright holder, and 463 you cure the violation prior to 30 days after your receipt of the notice. 464 </simpara> 465 <simpara> 466 Termination of your rights under this section does not terminate the 467 licenses of parties who have received copies or rights from you under this 468 License. If your rights have been terminated and not permanently 469 reinstated, receipt of a copy of some or all of the same material does not 470 give you any rights to use it. 471 </simpara> 472 <bridgehead xml:id="fdl-1-section10" renderas="sect2"> 473 10.
