1 # GNU Free Documentation License 2 3 Version 1.3, 3 November 2008 4 5 Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, 6 Inc. <https://fsf.org/> 7 8 Everyone is permitted to copy and distribute verbatim copies of this 9 license document, but changing it is not allowed. 10 11 ## 0. PREAMBLE 12 13 The purpose of this License is to make a manual, textbook, or other 14 functional and useful document "free" in the sense of freedom: to 15 assure everyone the effective freedom to copy and redistribute it, 16 with or without modifying it, either commercially or noncommercially. 17 Secondarily, this License preserves for the author and publisher a way 18 to get credit for their work, while not being considered responsible 19 for modifications made by others. 20 21 This License is a kind of "copyleft", which means that derivative 22 works of the document must themselves be free in the same sense. It 23 complements the GNU General Public License, which is a copyleft 24 license designed for free software. 25 26 We have designed this License in order to use it for manuals for free 27 software, because free software needs free documentation: a free 28 program should come with manuals providing the same freedoms that the 29 software does. But this License is not limited to software manuals; it 30 can be used for any textual work, regardless of subject matter or 31 whether it is published as a printed book. We recommend this License 32 principally for works whose purpose is instruction or reference. 33 34 ## 1. APPLICABILITY AND DEFINITIONS 35 36 This License applies to any manual or other work, in any medium, that 37 contains a notice placed by the copyright holder saying it can be 38 distributed under the terms of this License. Such a notice grants a 39 world-wide, royalty-free license, unlimited in duration, to use that 40 work under the conditions stated herein. The "Document", below, refers 41 to any such manual or work. Any member of the public is a licensee, 42 and is addressed as "you". You accept the license if you copy, modify 43 or distribute the work in a way requiring permission under copyright 44 law. 45 46 A "Modified Version" of the Document means any work containing the 47 Document or a portion of it, either copied verbatim, or with 48 modifications and/or translated into another language. 49 50 A "Secondary Section" is a named appendix or a front-matter section of 51 the Document that deals exclusively with the relationship of the 52 publishers or authors of the Document to the Document's overall 53 subject (or to related matters) and contains nothing that could fall 54 directly within that overall subject. (Thus, if the Document is in 55 part a textbook of mathematics, a Secondary Section may not explain 56 any mathematics.) The relationship could be a matter of historical 57 connection with the subject or with related matters, or of legal, 58 commercial, philosophical, ethical or political position regarding 59 them. 60 61 The "Invariant Sections" are certain Secondary Sections whose titles 62 are designated, as being those of Invariant Sections, in the notice 63 that says that the Document is released under this License. If a 64 section does not fit the above definition of Secondary then it is not 65 allowed to be designated as Invariant. The Document may contain zero 66 Invariant Sections. If the Document does not identify any Invariant 67 Sections then there are none. 68 69 The "Cover Texts" are certain short passages of text that are listed, 70 as Front-Cover Texts or Back-Cover Texts, in the notice that says that 71 the Document is released under this License. A Front-Cover Text may be 72 at most 5 words, and a Back-Cover Text may be at most 25 words. 73 74 A "Transparent" copy of the Document means a machine-readable copy, 75 represented in a format whose specification is available to the 76 general public, that is suitable for revising the document 77 straightforwardly with generic text editors or (for images composed of 78 pixels) generic paint programs or (for drawings) some widely available 79 drawing editor, and that is suitable for input to text formatters or 80 for automatic translation to a variety of formats suitable for input 81 to text formatters. A copy made in an otherwise Transparent file 82 format whose markup, or absence of markup, has been arranged to thwart 83 or discourage subsequent modification by readers is not Transparent. 84 An image format is not Transparent if used for any substantial amount 85 of text. A copy that is not "Transparent" is called "Opaque". 86 87 Examples of suitable formats for Transparent copies include plain 88 ASCII without markup, Texinfo input format, LaTeX input format, SGML 89 or XML using a publicly available DTD, and standard-conforming simple 90 HTML, PostScript or PDF designed for human modification. Examples of 91 transparent image formats include PNG, XCF and JPG. Opaque formats 92 include proprietary formats that can be read and edited only by 93 proprietary word processors, SGML or XML for which the DTD and/or 94 processing tools are not generally available, and the 95 machine-generated HTML, PostScript or PDF produced by some word 96 processors for output purposes only. 97 98 The "Title Page" means, for a printed book, the title page itself, 99 plus such following pages as are needed to hold, legibly, the material 100 this License requires to appear in the title page. For works in 101 formats which do not have any title page as such, "Title Page" means 102 the text near the most prominent appearance of the work's title, 103 preceding the beginning of the body of the text. 104 105 The "publisher" means any person or entity that distributes copies of 106 the Document to the public. 107 108 A section "Entitled XYZ" means a named subunit of the Document whose 109 title either is precisely XYZ or contains XYZ in parentheses following 110 text that translates XYZ in another language. (Here XYZ stands for a 111 specific section name mentioned below, such as "Acknowledgements", 112 "Dedications", "Endorsements", or "History".) To "Preserve the Title" 113 of such a section when you modify the Document means that it remains a 114 section "Entitled XYZ" according to this definition. 115 116 The Document may include Warranty Disclaimers next to the notice which 117 states that this License applies to the Document. These Warranty 118 Disclaimers are considered to be included by reference in this 119 License, but only as regards disclaiming warranties: any other 120 implication that these Warranty Disclaimers may have is void and has 121 no effect on the meaning of this License. 122 123 ## 2. VERBATIM COPYING 124 125 You may copy and distribute the Document in any medium, either 126 commercially or noncommercially, provided that this License, the 127 copyright notices, and the license notice saying this License applies 128 to the Document are reproduced in all copies, and that you add no 129 other conditions whatsoever to those of this License. You may not use 130 technical measures to obstruct or control the reading or further 131 copying of the copies you make or distribute. However, you may accept 132 compensation in exchange for copies. If you distribute a large enough 133 number of copies you must also follow the conditions in section 3. 134 135 You may also lend copies, under the same conditions stated above, and 136 you may publicly display copies. 137 138 ## 3. COPYING IN QUANTITY 139 140 If you publish printed copies (or copies in media that commonly have 141 printed covers) of the Document, numbering more than 100, and the 142 Document's license notice requires Cover Texts, you must enclose the 143 copies in covers that carry, clearly and legibly, all these Cover 144 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on 145 the back cover. Both covers must also clearly and legibly identify you 146 as the publisher of these copies. The front cover must present the 147 full title with all words of the title equally prominent and visible. 148 You may add other material on the covers in addition. Copying with 149 changes limited to the covers, as long as they preserve the title of 150 the Document and satisfy these conditions, can be treated as verbatim 151 copying in other respects. 152 153 If the required texts for either cover are too voluminous to fit 154 legibly, you should put the first ones listed (as many as fit 155 reasonably) on the actual cover, and continue the rest onto adjacent 156 pages. 157 158 If you publish or distribute Opaque copies of the Document numbering 159 more than 100, you must either include a machine-readable Transparent 160 copy along with each Opaque copy, or state in or with each Opaque copy 161 a computer-network location from which the general network-using 162 public has access to download using public-standard network protocols 163 a complete Transparent copy of the Document, free of added material. 164 If you use the latter option, you must take reasonably prudent steps, 165 when you begin distribution of Opaque copies in quantity, to ensure 166 that this Transparent copy will remain thus accessible at the stated 167 location until at least one year after the last time you distribute an 168 Opaque copy (directly or through your agents or retailers) of that 169 edition to the public. 170 171 It is requested, but not required, that you contact the authors of the 172 Document well before redistributing any large number of copies, to 173 give them a chance to provide you with an updated version of the 174 Document. 175 176 ## 4. MODIFICATIONS 177 178 You may copy and distribute a Modified Version of the Document under 179 the conditions of sections 2 and 3 above, provided that you release 180 the Modified Version under precisely this License, with the Modified 181 Version filling the role of the Document, thus licensing distribution 182 and modification of the Modified Version to whoever possesses a copy 183 of it. In addition, you must do these things in the Modified Version: 184 185 - A. Use in the Title Page (and on the covers, if any) a title 186 distinct from that of the Document, and from those of previous 187 versions (which should, if there were any, be listed in the 188 History section of the Document). You may use the same title as a 189 previous version if the original publisher of that version 190 gives permission. 191 - B. List on the Title Page, as authors, one or more persons or 192 entities responsible for authorship of the modifications in the 193 Modified Version, together with at least five of the principal 194 authors of the Document (all of its principal authors, if it has 195 fewer than five), unless they release you from this requirement. 196 - C. State on the Title page the name of the publisher of the 197 Modified Version, as the publisher. 198 - D. Preserve all the copyright notices of the Document. 199 - E. Add an appropriate copyright notice for your modifications 200 adjacent to the other copyright notices. 201 - F. Include, immediately after the copyright notices, a license 202 notice giving the public permission to use the Modified Version 203 under the terms of this License, in the form shown in the 204 Addendum below. 205 - G. Preserve in that license notice the full lists of Invariant 206 Sections and required Cover Texts given in the Document's 207 license notice. 208 - H. Include an unaltered copy of this License. 209 - I. Preserve the section Entitled "History", Preserve its Title, 210 and add to it an item stating at least the title, year, new 211 authors, and publisher of the Modified Version as given on the 212 Title Page. If there is no section Entitled "History" in the 213 Document, create one stating the title, year, authors, and 214 publisher of the Document as given on its Title Page, then add an 215 item describing the Modified Version as stated in the 216 previous sentence. 217 - J. Preserve the network location, if any, given in the Document 218 for public access to a Transparent copy of the Document, and 219 likewise the network locations given in the Document for previous 220 versions it was based on. These may be placed in the "History" 221 section. You may omit a network location for a work that was 222 published at least four years before the Document itself, or if 223 the original publisher of the version it refers to 224 gives permission. 225 - K. For any section Entitled "Acknowledgements" or "Dedications", 226 Preserve the Title of the section, and preserve in the section all 227 the substance and tone of each of the contributor acknowledgements 228 and/or dedications given therein. 229 - L. Preserve all the Invariant Sections of the Document, unaltered 230 in their text and in their titles. Section numbers or the 231 equivalent are not considered part of the section titles. 232 - M. Delete any section Entitled "Endorsements". Such a section may 233 not be included in the Modified Version. 234 - N. Do not retitle any existing section to be Entitled 235 "Endorsements" or to conflict in title with any Invariant Section. 236 - O. Preserve any Warranty Disclaimers. 237 238 If the Modified Version includes new front-matter sections or 239 appendices that qualify as Secondary Sections and contain no material 240 copied from the Document, you may at your option designate some or all 241 of these sections as invariant. To do this, add their titles to the 242 list of Invariant Sections in the Modified Version's license notice. 243 These titles must be distinct from any other section titles. 244 245 You may add a section Entitled "Endorsements", provided it contains 246 nothing but endorsements of your Modified Version by various 247 parties—for example, statements of peer review or that the text has 248 been approved by an organization as the authoritative definition of a 249 standard. 250 251 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 253 of Cover Texts in the Modified Version. Only one passage of 254 Front-Cover Text and one of Back-Cover Text may be added by (or 255 through arrangements made by) any one entity. If the Document already 256 includes a cover text for the same cover, previously added by you or 257 by arrangement made by the same entity you are acting on behalf of, 258 you may not add another; but you may replace the old one, on explicit 259 permission from the previous publisher that added the old one. 260 261 The author(s) and publisher(s) of the Document do not by this License 262 give permission to use their names for publicity for or to assert or 263 imply endorsement of any Modified Version. 264 265 ## 5. COMBINING DOCUMENTS 266 267 You may combine the Document with other documents released under this 268 License, under the terms defined in section 4 above for modified 269 versions, provided that you include in the combination all of the 270 Invariant Sections of all of the original documents, unmodified, and 271 list them all as Invariant Sections of your combined work in its 272 license notice, and that you preserve all their Warranty Disclaimers. 273 274 The combined work need only contain one copy of this License, and 275 multiple identical Invariant Sections may be replaced with a single 276 copy. If there are multiple Invariant Sections with the same name but 277 different contents, make the title of each such section unique by 278 adding at the end of it, in parentheses, the name of the original 279 author or publisher of that section if known, or else a unique number. 280 Make the same adjustment to the section titles in the list of 281 Invariant Sections in the license notice of the combined work. 282 283 In the combination, you must combine any sections Entitled "History" 284 in the various original documents, forming one section Entitled 285 "History"; likewise combine any sections Entitled "Acknowledgements", 286 and any sections Entitled "Dedications". You must delete all sections 287 Entitled "Endorsements". 288 289 ## 6. COLLECTIONS OF DOCUMENTS 290 291 You may make a collection consisting of the Document and other 292 documents released under this License, and replace the individual 293 copies of this License in the various documents with a single copy 294 that is included in the collection, provided that you follow the rules 295 of this License for verbatim copying of each of the documents in all 296 other respects. 297 298 You may extract a single document from such a collection, and 299 distribute it individually under this License, provided you insert a 300 copy of this License into the extracted document, and follow this 301 License in all other respects regarding verbatim copying of that 302 document. 303 304 ## 7. AGGREGATION WITH INDEPENDENT WORKS 305 306 A compilation of the Document or its derivatives with other separate 307 and independent documents or works, in or on a volume of a storage or 308 distribution medium, is called an "aggregate" if the copyright 309 resulting from the compilation is not used to limit the legal rights 310 of the compilation's users beyond what the individual works permit. 311 When the Document is included in an aggregate, this License does not 312 apply to the other works in the aggregate which are not themselves 313 derivative works of the Document. 314 315 If the Cover Text requirement of section 3 is applicable to these 316 copies of the Document, then if the Document is less than one half of 317 the entire aggregate, the Document's Cover Texts may be placed on 318 covers that bracket the Document within the aggregate, or the 319 electronic equivalent of covers if the Document is in electronic form. 320 Otherwise they must appear on printed covers that bracket the whole 321 aggregate. 322 323 ## 8. TRANSLATION 324 325 Translation is considered a kind of modification, so you may 326 distribute translations of the Document under the terms of section 4. 327 Replacing Invariant Sections with translations requires special 328 permission from their copyright holders, but you may include 329 translations of some or all Invariant Sections in addition to the 330 original versions of these Invariant Sections. You may include a 331 translation of this License, and all the license notices in the 332 Document, and any Warranty Disclaimers, provided that you also include 333 the original English version of this License and the original versions 334 of those notices and disclaimers. In case of a disagreement between 335 the translation and the original version of this License or a notice 336 or disclaimer, the original version will prevail. 337 338 If a section in the Document is Entitled "Acknowledgements", 339 "Dedications", or "History", the requirement (section 4) to Preserve 340 its Title (section 1) will typically require changing the actual 341 title. 342 343 ## 9. TERMINATION 344 345 You may not copy, modify, sublicense, or distribute the Document 346 except as expressly provided under this License. Any attempt otherwise 347 to copy, modify, sublicense, or distribute it is void, and will 348 automatically terminate your rights under this License. 349 350 However, if you cease all violation of this License, then your license 351 from a particular copyright holder is reinstated (a) provisionally, 352 unless and until the copyright holder explicitly and finally 353 terminates your license, and (b) permanently, if the copyright holder 354 fails to notify you of the violation by some reasonable means prior to 355 60 days after the cessation. 356 357 Moreover, your license from a particular copyright holder is 358 reinstated permanently if the copyright holder notifies you of the 359 violation by some reasonable means, this is the first time you have 360 received notice of violation of this License (for any work) from that 361 copyright holder, and you cure the violation prior to 30 days after 362 your receipt of the notice. 363 364 Termination of your rights under this section does not terminate the 365 licenses of parties who have received copies or rights from you under 366 this License. If your rights have been terminated and not permanently 367 reinstated, receipt of a copy of some or all of the same material does 368 not give you any rights to use it. 369 370 ## 10. FUTURE REVISIONS OF THIS LICENSE 371 372 The Free Software Foundation may publish new, revised versions of the 373 GNU Free Documentation License from time to time. Such new versions 374 will be similar in spirit to the present version, but may differ in 375 detail to address new problems or concerns. See 376 <https://www.gnu.org/licenses/>. 377 378 Each version of the License is given a distinguishing version number. 379 If the Document specifies that a particular numbered version of this 380 License "or any later version" applies to it, you have the option of 381 following the terms and conditions either of that specified version or 382 of any later version that has been published (not as a draft) by the 383 Free Software Foundation. If the Document does not specify a version 384 number of this License, you may choose any version ever published (not 385 as a draft) by the Free Software Foundation. If the Document specifies 386 that a proxy can decide which future versions of this License can be 387 used, that proxy's public statement of acceptance of a version 388 permanently authorizes you to choose that version for the Document. 389 390 ## 11. RELICENSING 391 392 "Massive Multiauthor Collaboration Site" (or "MMC Site") means any 393 World Wide Web server that publishes copyrightable works and also 394 provides prominent facilities for anybody to edit those works. A 395 public wiki that anybody can edit is an example of such a server. A 396 "Massive Multiauthor Collaboration" (or "MMC") contained in the site 397 means any set of copyrightable works thus published on the MMC site. 398 399 "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 400 license published by Creative Commons Corporation, a not-for-profit 401 corporation with a principal place of business in San Francisco, 402 California, as well as future copyleft versions of that license 403 published by that same organization. 404 405 "Incorporate" means to publish or republish a Document, in whole or in 406 part, as part of another Document. 407 408 An MMC is "eligible for relicensing" if it is licensed under this 409 License, and if all works that were first published under this License 410 somewhere other than this MMC, and subsequently incorporated in whole 411 or in part into the MMC, (1) had no cover texts or invariant sections, 412 and (2) were thus incorporated prior to November 1, 2008. 413 414 The operator of an MMC Site may republish an MMC contained in the site 415 under CC-BY-SA on the same site at any time before August 1, 2009, 416 provided the MMC is eligible for relicensing. 417 418 ## ADDENDUM: How to use this License for your documents 419 420 To use this License in a document you have written, include a copy of 421 the License in the document and put the following copyright and 422 license notices just after the title page: 423 424 Copyright (C) 2024 DECENTRALIZED CLIMATE FOUNDATION A.C. 425 Permission is granted to copy, distribute and/or modify this document 426 under the terms of the GNU Free Documentation License, Version 1.3 427 or any later version published by the Free Software Foundation; 428 with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. 429 A copy of the license is included in the section entitled "GNU 430 Free Documentation License". 431 432 If you have Invariant Sections, Front-Cover Texts and Back-Cover 433 Texts, replace the "with … Texts." line with this: 434 435 with the Invariant Sections being LIST THEIR TITLES, with the 436 Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. 437 438 If you have Invariant Sections without Cover Texts, or some other 439 combination of the three, merge those two alternatives to suit the 440 situation. 441 442 If your document contains nontrivial examples of program code, we 443 recommend releasing these examples in parallel under your choice of 444 free software license, such as the GNU General Public License, to 445 permit their use in free software.
