  6. Copyright @copyright{} 2000 Free Software Foundation, Inc.
  7. 59 Temple Place, Suite 330, Boston, MA 02111-1307, USA
  8. Everyone is permitted to copy and distribute verbatim copies
  9. of this license document, but changing it is not allowed.

  13. PREAMBLE
  14. The purpose of this License is to make a manual, textbook, or other
  15. written document @dfn{free} in the sense of freedom: to assure everyone
  16. the effective freedom to copy and redistribute it, with or without
  17. modifying it, either commercially or noncommercially. Secondarily,
  18. this License preserves for the author and publisher a way to get
  19. credit for their work, while not being considered responsible for
  20. modifications made by others.
  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. We have designed this License in order to use it for manuals for free
  26. software, because free software needs free documentation: a free
  27. program should come with manuals providing the same freedoms that the
  28. software does. But this License is not limited to software manuals;
  29. it can be used for any textual work, regardless of subject matter or
  30. whether it is published as a printed book. We recommend this License
  31. principally for works whose purpose is instruction or reference.
  32. @item
  33. APPLICABILITY AND DEFINITIONS
  34. This License applies to any manual or other work that contains a
  35. notice placed by the copyright holder saying it can be distributed
  36. under the terms of this License. The ``Document'', below, refers to any
  37. such manual or work. Any member of the public is a licensee, and is
  38. addressed as ``you''.
  39. A ``Modified Version'' of the Document means any work containing the
  40. Document or a portion of it, either copied verbatim, or with
  41. modifications and/or translated into another language.
  42. A ``Secondary Section'' is a named appendix or a front-matter section of
  43. the Document that deals exclusively with the relationship of the
  44. publishers or authors of the Document to the Document's overall subject
  45. (or to related matters) and contains nothing that could fall directly
  46. within that overall subject. (For example, if the Document is in part a
  47. textbook of mathematics, a Secondary Section may not explain any
  48. mathematics.) The relationship could be a matter of historical
  49. connection with the subject or with related matters, or of legal,
  50. commercial, philosophical, ethical or political position regarding
  51. them.
  52. The ``Invariant Sections'' are certain Secondary Sections whose titles
  53. are designated, as being those of Invariant Sections, in the notice
  54. that says that the Document is released under this License.
  55. The ``Cover Texts'' are certain short passages of text that are listed,
  56. as Front-Cover Texts or Back-Cover Texts, in the notice that says that
  57. the Document is released under this License.
  58. A ``Transparent'' copy of the Document means a machine-readable copy,
  59. represented in a format whose specification is available to the
  60. general public, whose contents can be viewed and edited directly and
  61. straightforwardly with generic text editors or (for images composed of
  62. pixels) generic paint programs or (for drawings) some widely available
  63. drawing editor, and that is suitable for input to text formatters or
  64. for automatic translation to a variety of formats suitable for input
  65. to text formatters. A copy made in an otherwise Transparent file
  66. format whose markup has been designed to thwart or discourage
  67. subsequent modification by readers is not Transparent. A copy that is
  68. not ``Transparent'' is called ``Opaque''.
  69. Examples of suitable formats for Transparent copies include plain
  70. @sc{ascii} without markup, Texinfo input format, La@TeX{} input format,
  71. @acronym{SGML} or @acronym{XML} using a publicly available
  72. @acronym{DTD}, and standard-conforming simple @acronym{HTML} designed
  73. for human modification. Opaque formats include PostScript,
  74. @acronym{PDF}, proprietary formats that can be read and edited only by
  75. proprietary word processors, @acronym{SGML} or @acronym{XML} for which
  76. the @acronym{DTD} and/or processing tools are not generally available,
  77. and the machine-generated @acronym{HTML} produced by some word
  78. processors for output purposes only.
  79. The ``Title Page'' means, for a printed book, the title page itself,
  80. plus such following pages as are needed to hold, legibly, the material
  81. this License requires to appear in the title page. For works in
  82. formats which do not have any title page as such, ``Title Page'' means
  83. the text near the most prominent appearance of the work's title,
  84. preceding the beginning of the body of the text.
  85. @item
  86. VERBATIM COPYING
  87. You may copy and distribute the Document in any medium, either
  88. commercially or noncommercially, provided that this License, the
  89. copyright notices, and the license notice saying this License applies
  90. to the Document are reproduced in all copies, and that you add no other
  91. conditions whatsoever to those of this License. You may not use
  92. technical measures to obstruct or control the reading or further
  93. copying of the copies you make or distribute. However, you may accept
  94. compensation in exchange for copies. If you distribute a large enough
  95. number of copies you must also follow the conditions in section 3.
  96. You may also lend copies, under the same conditions stated above, and
  97. you may publicly display copies.
  98. @item
  99. COPYING IN QUANTITY
  100. If you publish printed copies of the Document numbering more than 100,
  101. and the Document's license notice requires Cover Texts, you must enclose
  102. the copies in covers that carry, clearly and legibly, all these Cover
  103. Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
  104. the back cover. Both covers must also clearly and legibly identify
  105. you as the publisher of these copies. The front cover must present
  106. the full title with all words of the title equally prominent and
  107. visible. You may add other material on the covers in addition.
  108. Copying with changes limited to the covers, as long as they preserve
  109. the title of the Document and satisfy these conditions, can be treated
  110. as verbatim copying in other respects.
  111. If the required texts for either cover are too voluminous to fit
  112. legibly, you should put the first ones listed (as many as fit
  113. reasonably) on the actual cover, and continue the rest onto adjacent
  114. pages.
  115. If you publish or distribute Opaque copies of the Document numbering
  116. more than 100, you must either include a machine-readable Transparent
  117. copy along with each Opaque copy, or state in or with each Opaque copy
  118. a publicly-accessible computer-network location containing a complete
  119. Transparent copy of the Document, free of added material, which the
  120. general network-using public has access to download anonymously at no
  121. charge using public-standard network protocols. If you use the latter
  122. option, you must take reasonably prudent steps, when you begin
  123. distribution of Opaque copies in quantity, to ensure that this
  124. Transparent copy will remain thus accessible at the stated location
  125. until at least one year after the last time you distribute an Opaque
  126. copy (directly or through your agents or retailers) of that edition to
  127. the public.
  128. It is requested, but not required, that you contact the authors of the
  129. Document well before redistributing any large number of copies, to give
  130. them a chance to provide you with an updated version of the Document.
  131. @item
  132. MODIFICATIONS
  133. You may copy and distribute a Modified Version of the Document under
  134. the conditions of sections 2 and 3 above, provided that you release
  135. the Modified Version under precisely this License, with the Modified
  136. Version filling the role of the Document, thus licensing distribution
  137. and modification of the Modified Version to whoever possesses a copy
  138. of it. In addition, you must do these things in the Modified Version:
  139. @enumerate A
  140. @item
  141. Use in the Title Page (and on the covers, if any) a title distinct
  142. from that of the Document, and from those of previous versions
  143. (which should, if there were any, be listed in the History section
  144. of the Document). You may use the same title as a previous version
  145. if the original publisher of that version gives permission.
  146. @item
  147. List on the Title Page, as authors, one or more persons or entities
  148. responsible for authorship of the modifications in the Modified
  149. Version, together with at least five of the principal authors of the
  150. Document (all of its principal authors, if it has less than five).
  151. @item
  152. State on the Title page the name of the publisher of the
  153. Modified Version, as the publisher.
  154. @item
  155. Preserve all the copyright notices of the Document.
  156. @item
  157. Add an appropriate copyright notice for your modifications
  158. adjacent to the other copyright notices.
  159. @item
  160. Include, immediately after the copyright notices, a license notice
  161. giving the public permission to use the Modified Version under the
  162. terms of this License, in the form shown in the Addendum below.
  163. @item
  164. Preserve in that license notice the full lists of Invariant Sections
  165. and required Cover Texts given in the Document's license notice.
  166. @item
  167. Include an unaltered copy of this License.
  168. @item
  169. Preserve the section entitled ``History'', and its title, and add to
  170. it an item stating at least the title, year, new authors, and
  171. publisher of the Modified Version as given on the Title Page. If
  172. there is no section entitled ``History'' in the Document, create one
  173. stating the title, year, authors, and publisher of the Document as
  174. given on its Title Page, then add an item describing the Modified
  175. Version as stated in the previous sentence.
  176. @item
  177. Preserve the network location, if any, given in the Document for
  178. public access to a Transparent copy of the Document, and likewise
  179. the network locations given in the Document for previous versions
  180. it was based on. These may be placed in the ``History'' section.
  181. You may omit a network location for a work that was published at
  182. least four years before the Document itself, or if the original
  183. publisher of the version it refers to gives permission.
  184. @item
  185. In any section entitled ``Acknowledgments'' or ``Dedications'',
  186. preserve the section's title, and preserve in the section all the
  187. substance and tone of each of the contributor acknowledgments
  188. and/or dedications given therein.
  189. @item
  190. Preserve all the Invariant Sections of the Document,
  191. unaltered in their text and in their titles. Section numbers
  192. or the equivalent are not considered part of the section titles.
  193. @item
  194. Delete any section entitled ``Endorsements''. Such a section
  195. may not be included in the Modified Version.
  196. @item
  197. Do not retitle any existing section as ``Endorsements''
  198. or to conflict in title with any Invariant Section.
  199. @end enumerate
  200. If the Modified Version includes new front-matter sections or
  201. appendices that qualify as Secondary Sections and contain no material
  202. copied from the Document, you may at your option designate some or all
  203. of these sections as invariant. To do this, add their titles to the
  204. list of Invariant Sections in the Modified Version's license notice.
  205. These titles must be distinct from any other section titles.
  206. You may add a section entitled ``Endorsements'', provided it contains
  207. nothing but endorsements of your Modified Version by various
  208. parties---for example, statements of peer review or that the text has
  209. been approved by an organization as the authoritative definition of a
  210. standard.
  211. You may add a passage of up to five words as a Front-Cover Text, and a
  212. passage of up to 25 words as a Back-Cover Text, to the end of the list
  213. of Cover Texts in the Modified Version. Only one passage of
  214. Front-Cover Text and one of Back-Cover Text may be added by (or
  215. through arrangements made by) any one entity. If the Document already
  216. includes a cover text for the same cover, previously added by you or
  217. by arrangement made by the same entity you are acting on behalf of,
  218. you may not add another; but you may replace the old one, on explicit
  219. permission from the previous publisher that added the old one.
  220. The author(s) and publisher(s) of the Document do not by this License
  221. give permission to use their names for publicity for or to assert or
  222. imply endorsement of any Modified Version.
  223. @item
  224. COMBINING DOCUMENTS
  225. You may combine the Document with other documents released under this
  226. License, under the terms defined in section 4 above for modified
  227. versions, provided that you include in the combination all of the
  228. Invariant Sections of all of the original documents, unmodified, and
  229. list them all as Invariant Sections of your combined work in its
  230. license notice.
  231. The combined work need only contain one copy of this License, and
  232. multiple identical Invariant Sections may be replaced with a single
  233. copy. If there are multiple Invariant Sections with the same name but
  234. different contents, make the title of each such section unique by
  235. adding at the end of it, in parentheses, the name of the original
  236. author or publisher of that section if known, or else a unique number.
  237. Make the same adjustment to the section titles in the list of
  238. Invariant Sections in the license notice of the combined work.
  239. In the combination, you must combine any sections entitled ``History''
  240. in the various original documents, forming one section entitled
  241. ``History''; likewise combine any sections entitled ``Acknowledgments'',
  242. and any sections entitled ``Dedications''. You must delete all sections
  243. entitled ``Endorsements.''
  244. @item
  245. COLLECTIONS OF DOCUMENTS
  246. You may make a collection consisting of the Document and other documents
  247. released under this License, and replace the individual copies of this
  248. License in the various documents with a single copy that is included in
  249. the collection, provided that you follow the rules of this License for
  250. verbatim copying of each of the documents in all other respects.
  251. You may extract a single document from such a collection, and distribute
  252. it individually under this License, provided you insert a copy of this
  253. License into the extracted document, and follow this License in all
  254. other respects regarding verbatim copying of that document.
  255. @item
  256. AGGREGATION WITH INDEPENDENT WORKS
  257. A compilation of the Document or its derivatives with other separate
  258. and independent documents or works, in or on a volume of a storage or
  259. distribution medium, does not as a whole count as a Modified Version
  260. of the Document, provided no compilation copyright is claimed for the
  261. compilation. Such a compilation is called an ``aggregate'', and this
  262. License does not apply to the other self-contained works thus compiled
  263. with the Document, on account of their being thus compiled, if they
  264. are not themselves derivative works of the Document.
  265. If the Cover Text requirement of section 3 is applicable to these
  266. copies of the Document, then if the Document is less than one quarter
  267. of the entire aggregate, the Document's Cover Texts may be placed on
  268. covers that surround only the Document within the aggregate.
  269. Otherwise they must appear on covers around the whole aggregate.
  270. @item
  271. TRANSLATION
  272. Translation is considered a kind of modification, so you may
  273. distribute translations of the Document under the terms of section 4.
  274. Replacing Invariant Sections with translations requires special
  275. permission from their copyright holders, but you may include
  276. translations of some or all Invariant Sections in addition to the
  277. original versions of these Invariant Sections. You may include a
  278. translation of this License provided that you also include the
  279. original English version of this License. In case of a disagreement
  280. between the translation and the original English version of this
  281. License, the original English version will prevail.
  282. @item
  283. TERMINATION
  284. You may not copy, modify, sublicense, or distribute the Document except
  285. as expressly provided for under this License. Any other attempt to
  286. copy, modify, sublicense or distribute the Document is void, and will
  287. automatically terminate your rights under this License. However,
  288. parties who have received copies, or rights, from you under this
  289. License will not have their licenses terminated so long as such
  290. parties remain in full compliance.
  291. @item
  292. FUTURE REVISIONS OF THIS LICENSE
  293. The Free Software Foundation may publish new, revised versions
  294. of the GNU Free Documentation License from time to time. Such new
  295. versions will be similar in spirit to the present version, but may
  296. differ in detail to address new problems or concerns. See
  297. @uref{http://www.gnu.org/copyleft/}.
  298. Each version of the License is given a distinguishing version number.
  299. If the Document specifies that a particular numbered version of this
  300. License ``or any later version'' applies to it, you have the option of
  301. following the terms and conditions either of that specified version or
  302. of any later version that has been published (not as a draft) by the
  303. Free Software Foundation. If the Document does not specify a version
  304. number of this License, you may choose any version ever published (not
  305. as a draft) by the Free Software Foundation.
  306. @end enumerate
  307. @page
  308. @appendixsubsec ADDENDUM: How to use this License for your documents
  309. To use this License in a document you have written, include a copy of
  310. the License in the document and put the following copyright and
  311. license notices just after the title page:
  312. @smallexample
  313. @group
  314. Copyright (C) @var{year} @var{your name}.
  315. Permission is granted to copy, distribute and/or modify this document
  316. under the terms of the GNU Free Documentation License, Version 1.1
  317. or any later version published by the Free Software Foundation;
  318. with the Invariant Sections being @var{list their titles}, with the
  319. Front-Cover Texts being @var{list}, and with the Back-Cover Texts being @var{list}.
  320. A copy of the license is included in the section entitled ``GNU
  321. Free Documentation License''.
  322. @end group
  323. @end smallexample
  324. If you have no Invariant Sections, write ``with no Invariant Sections''
  325. instead of saying which ones are invariant. If you have no
  326. Front-Cover Texts, write ``no Front-Cover Texts'' instead of
  327. ``Front-Cover Texts being @var{list}''; likewise for Back-Cover Texts.
  328. If your document contains nontrivial examples of program code, we
  329. recommend releasing these examples in parallel under your choice of
  330. free software license, such as the GNU General Public License,
  331. to permit their use in free software.
