  158. .Sp
  159. The purpose of this License is to make a manual, textbook, or other
  160. functional and useful document \fIfree\fR in the sense of freedom: to
  161. assure everyone the effective freedom to copy and redistribute it,
  162. with or without modifying it, either commercially or noncommercially.
  163. Secondarily, this License preserves for the author and publisher a way
  164. to get credit for their work, while not being considered responsible
  165. for modifications made by others.
  166. .Sp
  167. This License is a kind of \*(L"copyleft\*(R", which means that derivative
  168. works of the document must themselves be free in the same sense. It
  169. complements the \s-1GNU\s0 General Public License, which is a copyleft
  170. license designed for free software.
  171. .Sp
  172. We have designed this License in order to use it for manuals for free
  173. software, because free software needs free documentation: a free
  174. program should come with manuals providing the same freedoms that the
  175. software does. But this License is not limited to software manuals;
  176. it can be used for any textual work, regardless of subject matter or
  177. whether it is published as a printed book. We recommend this License
  178. principally for works whose purpose is instruction or reference.
  179. .IP "1." 4

  181. \&\s-1APPLICABILITY\s0 \s-1AND\s0 \s-1DEFINITIONS\s0
  182. .Sp
  183. This License applies to any manual or other work, in any medium, that
  184. contains a notice placed by the copyright holder saying it can be
  185. distributed under the terms of this License. Such a notice grants a
  186. world-wide, royalty-free license, unlimited in duration, to use that
  187. work under the conditions stated herein. The \*(L"Document\*(R", below,
  188. refers to any such manual or work. Any member of the public is a
  189. licensee, and is addressed as \*(L"you\*(R". You accept the license if you
  190. copy, modify or distribute the work in a way requiring permission
  191. under copyright law.
  192. .Sp
  193. A \*(L"Modified Version\*(R" of the Document means any work containing the
  194. Document or a portion of it, either copied verbatim, or with
  195. modifications and/or translated into another language.
  196. .Sp
  197. A \*(L"Secondary Section\*(R" is a named appendix or a front-matter section
  198. of the Document that deals exclusively with the relationship of the
  199. publishers or authors of the Document to the Document's overall
  200. subject (or to related matters) and contains nothing that could fall
  201. directly within that overall subject. (Thus, if the Document is in
  202. part a textbook of mathematics, a Secondary Section may not explain
  203. any mathematics.) The relationship could be a matter of historical
  204. connection with the subject or with related matters, or of legal,
  205. commercial, philosophical, ethical or political position regarding
  206. them.
  207. .Sp
  208. The \*(L"Invariant Sections\*(R" are certain Secondary Sections whose titles
  209. are designated, as being those of Invariant Sections, in the notice
  210. that says that the Document is released under this License. If a
  211. section does not fit the above definition of Secondary then it is not
  212. allowed to be designated as Invariant. The Document may contain zero
  213. Invariant Sections. If the Document does not identify any Invariant
  214. Sections then there are none.
  215. .Sp
  216. The \*(L"Cover Texts\*(R" are certain short passages of text that are listed,
  217. as Front-Cover Texts or Back-Cover Texts, in the notice that says that
  218. the Document is released under this License. A Front-Cover Text may
  219. be at most 5 words, and a Back-Cover Text may be at most 25 words.
  220. .Sp
  221. A \*(L"Transparent\*(R" copy of the Document means a machine-readable copy,
  222. represented in a format whose specification is available to the
  223. general public, that is suitable for revising the document
  224. straightforwardly with generic text editors or (for images composed of
  225. pixels) generic paint programs or (for drawings) some widely available
  226. drawing editor, and that is suitable for input to text formatters or
  227. for automatic translation to a variety of formats suitable for input
  228. to text formatters. A copy made in an otherwise Transparent file
  229. format whose markup, or absence of markup, has been arranged to thwart
  230. or discourage subsequent modification by readers is not Transparent.
  231. An image format is not Transparent if used for any substantial amount
  232. of text. A copy that is not \*(L"Transparent\*(R" is called \*(L"Opaque\*(R".
  233. .Sp
  234. Examples of suitable formats for Transparent copies include plain
  235. \&\s-1ASCII\s0 without markup, Texinfo input format, LaTeX input
  236. format, \s-1SGML\s0 or \s-1XML\s0 using a publicly available
  237. \&\s-1DTD\s0, and standard-conforming simple \s-1HTML\s0,
  238. PostScript or \s-1PDF\s0 designed for human modification. Examples
  239. of transparent image formats include \s-1PNG\s0, \s-1XCF\s0 and
  240. \&\s-1JPG\s0. Opaque formats include proprietary formats that can be
  241. read and edited only by proprietary word processors, \s-1SGML\s0 or
  242. \&\s-1XML\s0 for which the \s-1DTD\s0 and/or processing tools are
  243. not generally available, and the machine-generated \s-1HTML\s0,
  244. PostScript or \s-1PDF\s0 produced by some word processors for
  245. output purposes only.
  246. .Sp
  247. The \*(L"Title Page\*(R" means, for a printed book, the title page itself,
  248. plus such following pages as are needed to hold, legibly, the material
  249. this License requires to appear in the title page. For works in
  250. formats which do not have any title page as such, \*(L"Title Page\*(R" means
  251. the text near the most prominent appearance of the work's title,
  252. preceding the beginning of the body of the text.
  253. .Sp
  254. The \*(L"publisher\*(R" means any person or entity that distributes copies
  255. of the Document to the public.
  256. .Sp
  257. A section \*(L"Entitled \s-1XYZ\s0\*(R" means a named subunit of the Document whose
  258. title either is precisely \s-1XYZ\s0 or contains \s-1XYZ\s0 in parentheses following
  259. text that translates \s-1XYZ\s0 in another language. (Here \s-1XYZ\s0 stands for a
  260. specific section name mentioned below, such as \*(L"Acknowledgements\*(R",
  261. \&\*(L"Dedications\*(R", \*(L"Endorsements\*(R", or \*(L"History\*(R".) To \*(L"Preserve the Title\*(R"
  262. of such a section when you modify the Document means that it remains a
  263. section \*(L"Entitled \s-1XYZ\s0\*(R" according to this definition.
  264. .Sp
  265. The Document may include Warranty Disclaimers next to the notice which
  266. states that this License applies to the Document. These Warranty
  267. Disclaimers are considered to be included by reference in this
  268. License, but only as regards disclaiming warranties: any other
  269. implication that these Warranty Disclaimers may have is void and has
  270. no effect on the meaning of this License.

  273. \&\s-1VERBATIM\s0 \s-1COPYING\s0
  274. .Sp
  275. You may copy and distribute the Document in any medium, either
  276. commercially or noncommercially, provided that this License, the
  277. copyright notices, and the license notice saying this License applies
  278. to the Document are reproduced in all copies, and that you add no other
  279. conditions whatsoever to those of this License. You may not use
  280. technical measures to obstruct or control the reading or further
  281. copying of the copies you make or distribute. However, you may accept
  282. compensation in exchange for copies. If you distribute a large enough
  283. number of copies you must also follow the conditions in section 3.
  284. .Sp
  285. You may also lend copies, under the same conditions stated above, and
  286. you may publicly display copies.
  287. .IP "3." 4
  288. .IX Item "3."
  289. \&\s-1COPYING\s0 \s-1IN\s0 \s-1QUANTITY\s0
  290. .Sp
  291. If you publish printed copies (or copies in media that commonly have
  292. printed covers) of the Document, numbering more than 100, and the
  293. Document's license notice requires Cover Texts, you must enclose the
  294. copies in covers that carry, clearly and legibly, all these Cover
  295. Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
  296. the back cover. Both covers must also clearly and legibly identify
  297. you as the publisher of these copies. The front cover must present
  298. the full title with all words of the title equally prominent and
  299. visible. You may add other material on the covers in addition.
  300. Copying with changes limited to the covers, as long as they preserve
  301. the title of the Document and satisfy these conditions, can be treated
  302. as verbatim copying in other respects.
  303. .Sp
  304. If the required texts for either cover are too voluminous to fit
  305. legibly, you should put the first ones listed (as many as fit
  306. reasonably) on the actual cover, and continue the rest onto adjacent
  307. pages.
  308. .Sp
  309. If you publish or distribute Opaque copies of the Document numbering
  310. more than 100, you must either include a machine-readable Transparent
  311. copy along with each Opaque copy, or state in or with each Opaque copy
  312. a computer-network location from which the general network-using
  313. public has access to download using public-standard network protocols
  314. a complete Transparent copy of the Document, free of added material.
  315. If you use the latter option, you must take reasonably prudent steps,

  454. The combined work need only contain one copy of this License, and
  455. multiple identical Invariant Sections may be replaced with a single
  456. copy. If there are multiple Invariant Sections with the same name but
  457. different contents, make the title of each such section unique by
  458. adding at the end of it, in parentheses, the name of the original
  459. author or publisher of that section if known, or else a unique number.

  486. A compilation of the Document or its derivatives with other separate
  487. and independent documents or works, in or on a volume of a storage or
  488. distribution medium, is called an \*(L"aggregate\*(R" if the copyright
  489. resulting from the compilation is not used to limit the legal rights
  490. of the compilation's users beyond what the individual works permit.
  491. When the Document is included in an aggregate, this License does not
  492. apply to the other works in the aggregate which are not themselves
  493. derivative works of the Document.
  494. .Sp
  495. If the Cover Text requirement of section 3 is applicable to these
  496. copies of the Document, then if the Document is less than one half of
  497. the entire aggregate, the Document's Cover Texts may be placed on
  498. covers that bracket the Document within the aggregate, or the
  499. electronic equivalent of covers if the Document is in electronic form.
  500. Otherwise they must appear on printed covers that bracket the whole

  505. .Sp
  506. Translation is considered a kind of modification, so you may
  507. distribute translations of the Document under the terms of section 4.
  508. Replacing Invariant Sections with translations requires special
  509. permission from their copyright holders, but you may include
  510. translations of some or all Invariant Sections in addition to the
  511. original versions of these Invariant Sections. You may include a
  512. translation of this License, and all the license notices in the
  513. Document, and any Warranty Disclaimers, provided that you also include
  514. the original English version of this License and the original versions
  515. of those notices and disclaimers. In case of a disagreement between
  516. the translation and the original version of this License or a notice
  517. or disclaimer, the original version will prevail.
  518. .Sp
  519. If a section in the Document is Entitled \*(L"Acknowledgements\*(R",
  520. \&\*(L"Dedications\*(R", or \*(L"History\*(R", the requirement (section 4) to Preserve
  521. its Title (section 1) will typically require changing the actual
  522. title.

  527. You may not copy, modify, sublicense, or distribute the Document
  528. except as expressly provided under this License. Any attempt
  529. otherwise to copy, modify, sublicense, or distribute it is void, and
  530. will automatically terminate your rights under this License.
  531. .Sp
  532. However, if you cease all violation of this License, then your license
  533. from a particular copyright holder is reinstated (a) provisionally,
  534. unless and until the copyright holder explicitly and finally
  535. terminates your license, and (b) permanently, if the copyright holder
  536. fails to notify you of the violation by some reasonable means prior to
  537. 60 days after the cessation.
  538. .Sp
  539. Moreover, your license from a particular copyright holder is
  540. reinstated permanently if the copyright holder notifies you of the
  541. violation by some reasonable means, this is the first time you have
  542. received notice of violation of this License (for any work) from that
  543. copyright holder, and you cure the violation prior to 30 days after
  544. your receipt of the notice.
  545. .Sp
  546. Termination of your rights under this section does not terminate the
  547. licenses of parties who have received copies or rights from you under
  548. this License. If your rights have been terminated and not permanently
  549. reinstated, receipt of a copy of some or all of the same material does
  550. not give you any rights to use it.

  564. following the terms and conditions either of that specified version or
  565. of any later version that has been published (not as a draft) by the
  566. Free Software Foundation. If the Document does not specify a version
  567. number of this License, you may choose any version ever published (not
  568. as a draft) by the Free Software Foundation. If the Document
  569. specifies that a proxy can decide which future versions of this
  570. License can be used, that proxy's public statement of acceptance of a
