It 110complements the GNU General Public License, which is a copyleft 111license designed for free software. 112</p> 113<p>We have designed this License in order to use it for manuals for free 114software, because free software needs free documentation: a free 115program should come with manuals providing the same freedoms that the 116software does. But this License is not limited to software manuals; 117it can be used for any textual work, regardless of subject matter or 118whether it is published as a printed book. We recommend this License 119principally for works whose purpose is instruction or reference. 120</p> 121</li><li> APPLICABILITY AND DEFINITIONS 122 123<p>This License applies to any manual or other work, in any medium, that 124contains a notice placed by the copyright holder saying it can be 125distributed under the terms of this License. Such a notice grants a 126world-wide, royalty-free license, unlimited in duration, to use that 127work under the conditions stated herein. The “Document”, below, 128refers to any such manual or work. Any member of the public is a 129licensee, and is addressed as “you”. You accept the license if you 130copy, modify or distribute the work in a way requiring permission 131under copyright law. 132</p> 133<p>A “Modified Version” of the Document means any work containing the 134Document or a portion of it, either copied verbatim, or with 135modifications and/or translated into another language. 136</p> 137<p>A “Secondary Section” is a named appendix or a front-matter section 138of the Document that deals exclusively with the relationship of the 139publishers or authors of the Document to the Document’s overall 140subject (or to related matters) and contains nothing that could fall 141directly within that overall subject. (Thus, if the Document is in 142part a textbook of mathematics, a Secondary Section may not explain 143any mathematics.) The relationship could be a matter of historical 144connection with the subject or with related matters, or of legal, 145commercial, philosophical, ethical or political position regarding 146them. 147</p> 148<p>The “Invariant Sections” are certain Secondary Sections whose titles 149are designated, as being those of Invariant Sections, in the notice 150that says that the Document is released under this License. If a 151section does not fit the above definition of Secondary then it is not 152allowed to be designated as Invariant. The Document may contain zero 153Invariant Sections. If the Document does not identify any Invariant 154Sections then there are none. 155</p> 156<p>The “Cover Texts” are certain short passages of text that are listed, 157as Front-Cover Texts or Back-Cover Texts, in the notice that says that 158the Document is released under this License. A Front-Cover Text may 159be at most 5 words, and a Back-Cover Text may be at most 25 words. 160</p> 161<p>A “Transparent” copy of the Document means a machine-readable copy, 162represented in a format whose specification is available to the 163general public, that is suitable for revising the document 164straightforwardly with generic text editors or (for images composed of 165pixels) generic paint programs or (for drawings) some widely available 166drawing editor, and that is suitable for input to text formatters or 167for automatic translation to a variety of formats suitable for input 168to text formatters. A copy made in an otherwise Transparent file 169format whose markup, or absence of markup, has been arranged to thwart 170or discourage subsequent modification by readers is not Transparent. 171An image format is not Transparent if used for any substantial amount 172of text. A copy that is not “Transparent” is called “Opaque”. 173</p> 174<p>Examples of suitable formats for Transparent copies include plain 175<small>ASCII</small> without markup, Texinfo input format, LaTeX input 176format, <acronym>SGML</acronym> or <acronym>XML</acronym> using a publicly available 177<acronym>DTD</acronym>, and standard-conforming simple <acronym>HTML</acronym>, 178PostScript or <acronym>PDF</acronym> designed for human modification. Examples 179of transparent image formats include <acronym>PNG</acronym>, <acronym>XCF</acronym> and 180<acronym>JPG</acronym>. Opaque formats include proprietary formats that can be 181read and edited only by proprietary word processors, <acronym>SGML</acronym> or 182<acronym>XML</acronym> for which the <acronym>DTD</acronym> and/or processing tools are 183not generally available, and the machine-generated <acronym>HTML</acronym>, 184PostScript or <acronym>PDF</acronym> produced by some word processors for 185output purposes only. 186</p> 187<p>The “Title Page” means, for a printed book, the title page itself, 188plus such following pages as are needed to hold, legibly, the material 189this License requires to appear in the title page. For works in 190formats which do not have any title page as such, “Title Page” means 191the text near the most prominent appearance of the work’s title, 192preceding the beginning of the body of the text. 193</p> 194<p>The “publisher” means any person or entity that distributes copies 195of the Document to the public. 196</p> 197<p>A section “Entitled XYZ” means a named subunit of the Document whose 198title either is precisely XYZ or contains XYZ in parentheses following 199text that translates XYZ in another language. (Here XYZ stands for a 200specific section name mentioned below, such as “Acknowledgements”, 201“Dedications”, “Endorsements”, or “History”.) To “Preserve the Title” 202of such a section when you modify the Document means that it remains a 203section “Entitled XYZ” according to this definition. 204</p> 205<p>The Document may include Warranty Disclaimers next to the notice which 206states that this License applies to the Document. These Warranty 207Disclaimers are considered to be included by reference in this 208License, but only as regards disclaiming warranties: any other 209implication that these Warranty Disclaimers may have is void and has 210no effect on the meaning of this License. 211</p> 212</li><li> VERBATIM COPYING 213 214<p>You may copy and distribute the Document in any medium, either 215commercially or noncommercially, provided that this License, the 216copyright notices, and the license notice saying this License applies 217to the Document are reproduced in all copies, and that you add no other 218conditions whatsoever to those of this License. You may not use 219technical measures to obstruct or control the reading or further 220copying of the copies you make or distribute. However, you may accept 221compensation in exchange for copies. If you distribute a large enough 222number of copies you must also follow the conditions in section 3. 223</p> 224<p>You may also lend copies, under the same conditions stated above, and 225you may publicly display copies. 226</p> 227</li><li> COPYING IN QUANTITY 228 229<p>If you publish printed copies (or copies in media that commonly have 230printed covers) of the Document, numbering more than 100, and the 231Document’s license notice requires Cover Texts, you must enclose the 232copies in covers that carry, clearly and legibly, all these Cover 233Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on 234the back cover. Both covers must also clearly and legibly identify 235you as the publisher of these copies. The front cover must present 236the full title with all words of the title equally prominent and 237visible. You may add other material on the covers in addition. 238Copying with changes limited to the covers, as long as they preserve 239the title of the Document and satisfy these conditions, can be treated 240as verbatim copying in other respects. 241</p> 242<p>If the required texts for either cover are too voluminous to fit 243legibly, you should put the first ones listed (as many as fit 244reasonably) on the actual cover, and continue the rest onto adjacent 245pages. 246</p> 247<p>If you publish or distribute Opaque copies of the Document numbering 248more than 100, you must either include a machine-readable Transparent 249copy along with each Opaque copy, or state in or with each Opaque copy 250a computer-network location from which the general network-using 251public has access to download using public-standard network protocols 252a complete Transparent copy of the Document, free of added material. 253If you use the latter option, you must take reasonably prudent steps, 254when you begin distribution of Opaque copies in quantity, to ensure 255that this Transparent copy will remain thus accessible at the stated 256location until at least one year after the last time you distribute an 257Opaque copy (directly or through your agents or retailers) of that 258edition to the public. 259</p> 260<p>It is requested, but not required, that you contact the authors of the 261Document well before redistributing any large number of copies, to give 262them a chance to provide you with an updated version of the Document. 263</p> 264</li><li> MODIFICATIONS 265 266<p>You may copy and distribute a Modified Version of the Document under 267the conditions of sections 2 and 3 above, provided that you release 268the Modified Version under precisely this License, with the Modified 269Version filling the role of the Document, thus licensing distribution 270and modification of the Modified Version to whoever possesses a copy 271of it. In addition, you must do these things in the Modified Version: 272</p> 273<ol type="A" start="1"> 274<li> Use in the Title Page (and on the covers, if any) a title distinct 275from that of the Document, and from those of previous versions 276(which should, if there were any, be listed in the History section 277of the Document). You may use the same title as a previous version 278if the original publisher of that version gives permission. 279 280</li><li> List on the Title Page, as authors, one or more persons or entities 281responsible for authorship of the modifications in the Modified 282Version, together with at least five of the principal authors of the 283Document (all of its principal authors, if it has fewer than five), 284unless they release you from this requirement. 285 286</li><li> State on the Title page the name of the publisher of the 287Modified Version, as the publisher. 288 289</li><li> Preserve all the copyright notices of the Document. 290 291</li><li> Add an appropriate copyright notice for your modifications 292adjacent to the other copyright notices. 293 294</li><li> Include, immediately after the copyright notices, a license notice 295giving the public permission to use the Modified Version under the 296terms of this License, in the form shown in the Addendum below. 297 298</li><li> Preserve in that license notice the full lists of Invariant Sections 299and required Cover Texts given in the Document’s license notice. 300 301</li><li> Include an unaltered copy of this License. 302 303</li><li> Preserve the section Entitled “History”, Preserve its Title, and add 304to it an item stating at least the title, year, new authors, and 305publisher of the Modified Version as given on the Title Page. If 306there is no section Entitled “History” in the Document, create one 307stating the title, year, authors, and publisher of the Document as 308given on its Title Page, then add an item describing the Modified 309Version as stated in the previous sentence. 310 311</li><li> Preserve the network location, if any, given in the Document for 312public access to a Transparent copy of the Document, and likewise 313the network locations given in the Document for previous versions 314it was based on. These may be placed in the “History” section. 315You may omit a network location for a work that was published at 316least four years before the Document itself, or if the original 317publisher of the version it refers to gives permission. 318 319</li><li> For any section Entitled “Acknowledgements” or “Dedications”, Preserve 320the Title of the section, and preserve in the section all the 321substance and tone of each of the contributor acknowledgements and/or 322dedications given therein. 323 324</li><li> Preserve all the Invariant Sections of the Document, 325unaltered in their text and in their titles. Section numbers 326or the equivalent are not considered part of the section titles. 327 328</li><li> Delete any section Entitled “Endorsements”. Such a section 329may not be included in the Modified Version. 330 331</li><li> Do not retitle any existing section to be Entitled “Endorsements” or 332to conflict in title with any Invariant Section. 333 334</li><li> Preserve any Warranty Disclaimers. 335</li></ol> 336 337<p>If the Modified Version includes new front-matter sections or 338appendices that qualify as Secondary Sections and contain no material 339copied from the Document, you may at your option designate some or all 340of these sections as invariant. To do this, add their titles to the 341list of Invariant Sections in the Modified Version’s license notice. 342These titles must be distinct from any other section titles. 343</p> 344<p>You may add a section Entitled “Endorsements”, provided it contains 345nothing but endorsements of your Modified Version by various 346parties—for example, statements of peer review or that the text has 347been approved by an organization as the authoritative definition of a 348standard. 349</p> 350<p>You may add a passage of up to five words as a Front-Cover Text, and a 351passage of up to 25 words as a Back-Cover Text, to the end of the list 352of Cover Texts in the Modified Version. Only one passage of 353Front-Cover Text and one of Back-Cover Text may be added by (or 354through arrangements made by) any one entity. If the Document already 355includes a cover text for the same cover, previously added by you or 356by arrangement made by the same entity you are acting on behalf of, 357you may not add another; but you may replace the old one, on explicit 358permission from the previous publisher that added the old one. 359</p> 360<p>The author(s) and publisher(s) of the Document do not by this License 361give permission to use their names for publicity for or to assert or 362imply endorsement of any Modified Version. 363</p> 364</li><li> COMBINING DOCUMENTS 365 366<p>You may combine the Document with other documents released under this 367License, under the terms defined in section 4 above for modified 368versions, provided that you include in the combination all of the 369Invariant Sections of all of the original documents, unmodified, and 370list them all as Invariant Sections of your combined work in its 371license notice, and that you preserve all their Warranty Disclaimers. 372</p> 373<p>The combined work need only contain one copy of this License, and 374multiple identical Invariant Sections may be replaced with a single 375copy. If there are multiple Invariant Sections with the same name but 376different contents, make the title of each such section unique by 377adding at the end of it, in parentheses, the name of the original 378author or publisher of that section if known, or else a unique number. 379Make the same adjustment to the section titles in the list of 380Invariant Sections in the license notice of the combined work. 381</p> 382<p>In the combination, you must combine any sections Entitled “History” 383in the various original documents, forming one section Entitled 384“History”; likewise combine any sections Entitled “Acknowledgements”, 385and any sections Entitled “Dedications”. You must delete all 386sections Entitled “Endorsements.” 387</p> 388</li><li> COLLECTIONS OF DOCUMENTS 389 390<p>You may make a collection consisting of the Document and other documents 391released under this License, and replace the individual copies of this 392License in the various documents with a single copy that is included in 393the collection, provided that you follow the rules of this License for 394verbatim copying of each of the documents in all other respects. 395</p> 396<p>You may extract a single document from such a collection, and distribute 397it individually under this License, provided you insert a copy of this 398License into the extracted document, and follow this License in all 399other respects regarding verbatim copying of that document. 400</p> 401</li><li> AGGREGATION WITH INDEPENDENT WORKS 402 403<p>A compilation of the Document or its derivatives with other separate 404and independent documents or works, in or on a volume of a storage or 405distribution medium, is called an “aggregate” if the copyright 406resulting from the compilation is not used to limit the legal rights 407of the compilation’s users beyond what the individual works permit. 408When the Document is included in an aggregate, this License does not 409apply to the other works in the aggregate which are not themselves 410derivative works of the Document. 411</p> 412<p>If the Cover Text requirement of section 3 is applicable to these 413copies of the Document, then if the Document is less than one half of 414the entire aggregate, the Document’s Cover Texts may be placed on 415covers that bracket the Document within the aggregate, or the 416electronic equivalent of covers if the Document is in electronic form. 417Otherwise they must appear on printed covers that bracket the whole 418aggregate. 419</p> 420</li><li> TRANSLATION 421 422<p>Translation is considered a kind of modification, so you may 423distribute translations of the Document under the terms of section 4. 424Replacing Invariant Sections with translations requires special 425permission from their copyright holders, but you may include 426translations of some or all Invariant Sections in addition to the 427original versions of these Invariant Sections. You may include a 428translation of this License, and all the license notices in the 429Document, and any Warranty Disclaimers, provided that you also include 430the original English version of this License and the original versions 431of those notices and disclaimers. In case of a disagreement between 432the translation and the original version of this License or a notice 433or disclaimer, the original version will prevail. 434</p> 435<p>If a section in the Document is Entitled “Acknowledgements”, 436“Dedications”, or “History”, the requirement (section 4) to Preserve 437its Title (section 1) will typically require changing the actual 438title. 439</p> 440</li><li> TERMINATION 441 442<p>You may not copy, modify, sublicense, or distribute the Document 443except as expressly provided under this License. Any attempt 444otherwise to copy, modify, sublicense, or distribute it is void, and 445will automatically terminate your rights under this License. 446</p> 447<p>However, if you cease all violation of this License, then your license 448from a particular copyright holder is reinstated (a) provisionally, 449unless and until the copyright holder explicitly and finally 450terminates your license, and (b) permanently, if the copyright holder 451fails to notify you of the violation by some reasonable means prior to 45260 days after the cessation. 453</p> 454<p>Moreover, your license from a particular copyright holder is 455reinstated permanently if the copyright holder notifies you of the 456violation by some reasonable means, this is the first time you have 457received notice of violation of this License (for any work) from that 458copyright holder, and you cure the violation prior to 30 days after 459your receipt of the notice. 460</p> 461<p>Termination of your rights under this section does not terminate the 462licenses of parties who have received copies or rights from you under 463this License. If your rights have been terminated and not permanently 464reinstated, receipt of a copy of some or all of the same material does 465not give you any rights to use it. 466</p> 467</li><li> FUTURE REVISIONS OF THIS LICENSE 468 469<p>The Free Software Foundation may publish new, revised versions 470of the GNU Free Documentation License from time to time. Such new 471versions will be similar in spirit to the present version, but may 472differ in detail to address new problems or concerns. See 473<a href="https://www.gnu.org/copyleft/">https://www.gnu.org/copyleft/</a>. 474</p> 475<p>Each version of the License is given a distinguishing version number. 476If the Document specifies that a particular numbered version of this 477License “or any later version” applies to it, you have the option of 478following the terms and conditions either of that specified version or 479of any later version that has been published (not as a draft) by the 480Free Software Foundation. If the Document does not specify a version 481number of this License, you may choose any version ever published (not 482as a draft) by the Free Software Foundation. If the Document 483specifies that a proxy can decide which future versions of this 484License can be used, that proxy’s public statement of acceptance of a 485version permanently authorizes you to choose that version for the 486Document. 487</p> 488</li><li> RELICENSING 489 490<p>“Massive Multiauthor Collaboration Site” (or “MMC Site”) means any 491World Wide Web server that publishes copyrightable works and also 492provides prominent facilities for anybody to edit those works. A 493public wiki that anybody can edit is an example of such a server. A 494“Massive Multiauthor Collaboration” (or “MMC”) contained in the 495site means any set of copyrightable works thus published on the MMC 496site. 497</p> 498<p>“CC-BY-SA” means the Creative Commons Attribution-Share Alike 3.0 499license published by Creative Commons Corporation, a not-for-profit 500corporation with a principal place of business in San Francisco, 501California, as well as future copyleft versions of that license 502published by that same organization. 503</p> 504<p>“Incorporate” means to publish or republish a Document, in whole or 505in part, as part of another Document. 506</p> 507<p>An MMC is “eligible for relicensing” if it is licensed under this 508License, and if all works that were first published under this License 509somewhere other than this MMC, and subsequently incorporated in whole 510or in part into the MMC, (1) had no cover texts or invariant sections, 511and (2) were thus incorporated prior to November 1, 2008. 512</p> 513<p>The operator of an MMC Site may republish an MMC contained in the site 514under CC-BY-SA on the same site at any time before August 1, 2009, 515provided the MMC is eligible for relicensing. 516</p> 517</li></ol> 518 519<div class="unnumberedsec" id="ADDENDUM_003a-How-to-use-this-License-for-your-documents"> 520<h3 class="unnumberedsec">ADDENDUM: How to use this License for your documents</h3> 521 522<p>To use this License in a document you have written, include a copy of 523the License in the document and put the following copyright and 524license notices just after the title page: 525</p> 526<div class="example"> 527<pre class="example"> Copyright (C) <var>year</var> <var>your name</var>. 528 Permission is granted to copy, distribute and/or modify this document 529 under the terms of the GNU Free Documentation License, Version 1.3 530 or any later version published by the Free Software Foundation; 531 with no Invariant Sections, no Front-Cover Texts, and no Back-Cover 532 Texts.
