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

  350. "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0

  354. published by that same organization.
  355. "Incorporate" means to publish or republish a Document, in whole or in
  356. part, as part of another Document.
  357. An MMC is "eligible for relicensing" if it is licensed under this
  358. License, and if all works that were first published under this License
  359. somewhere other than this MMC, and subsequently incorporated in whole or
  360. in part into the MMC, (1) had no cover texts or invariant sections, and
  361. (2) were thus incorporated prior to November 1, 2008.
  362. The operator of an MMC Site may republish an MMC contained in the site
  363. under CC-BY-SA on the same site at any time before August 1, 2009,
