1.21 +PREAMBLE
1.22 +
1.23 +The purpose of this License is to make a manual, textbook, or other
1.24 +functional and useful document @dfn{free} in the sense of freedom: to
1.25 +assure everyone the effective freedom to copy and redistribute it,
1.26 +with or without modifying it, either commercially or noncommercially.
1.27 +Secondarily, this License preserves for the author and publisher a way
1.28 +to get credit for their work, while not being considered responsible
1.29 +for modifications made by others.
1.30 +
1.31 +This License is a kind of ``copyleft'', which means that derivative
1.32 +works of the document must themselves be free in the same sense. It
1.33 +complements the GNU General Public License, which is a copyleft
1.34 +license designed for free software.
1.35 +
1.36 +We have designed this License in order to use it for manuals for free
1.37 +software, because free software needs free documentation: a free
1.38 +program should come with manuals providing the same freedoms that the
1.39 +software does. But this License is not limited to software manuals;
1.40 +it can be used for any textual work, regardless of subject matter or
1.41 +whether it is published as a printed book. We recommend this License
1.42 +principally for works whose purpose is instruction or reference.
1.43 +
1.44 +@item
1.45 +APPLICABILITY AND DEFINITIONS
1.46 +
1.47 +This License applies to any manual or other work, in any medium, that
1.48 +contains a notice placed by the copyright holder saying it can be
1.49 +distributed under the terms of this License. Such a notice grants a
1.50 +world-wide, royalty-free license, unlimited in duration, to use that
1.51 +work under the conditions stated herein. The ``Document'', below,
1.52 +refers to any such manual or work. Any member of the public is a
1.53 +licensee, and is addressed as ``you''. You accept the license if you
1.54 +copy, modify or distribute the work in a way requiring permission
1.55 +under copyright law.
1.56 +
1.57 +A ``Modified Version'' of the Document means any work containing the
1.58 +Document or a portion of it, either copied verbatim, or with
1.59 +modifications and/or translated into another language.
1.60 +
1.61 +A ``Secondary Section'' is a named appendix or a front-matter section
1.62 +of the Document that deals exclusively with the relationship of the
1.63 +publishers or authors of the Document to the Document's overall
1.64 +subject (or to related matters) and contains nothing that could fall
1.65 +directly within that overall subject. (Thus, if the Document is in
1.66 +part a textbook of mathematics, a Secondary Section may not explain
1.67 +any mathematics.) The relationship could be a matter of historical
1.68 +connection with the subject or with related matters, or of legal,
1.69 +commercial, philosophical, ethical or political position regarding
1.70 +them.
1.71 +
1.72 +The ``Invariant Sections'' are certain Secondary Sections whose titles
1.73 +are designated, as being those of Invariant Sections, in the notice
1.74 +that says that the Document is released under this License. If a
1.75 +section does not fit the above definition of Secondary then it is not
1.76 +allowed to be designated as Invariant. The Document may contain zero
1.77 +Invariant Sections. If the Document does not identify any Invariant
1.78 +Sections then there are none.
1.79 +
1.80 +The ``Cover Texts'' are certain short passages of text that are listed,
1.81 +as Front-Cover Texts or Back-Cover Texts, in the notice that says that
1.82 +the Document is released under this License. A Front-Cover Text may
1.83 +be at most 5 words, and a Back-Cover Text may be at most 25 words.
1.84 +
1.85 +A ``Transparent'' copy of the Document means a machine-readable copy,
1.86 +represented in a format whose specification is available to the
1.87 +general public, that is suitable for revising the document
1.88 +straightforwardly with generic text editors or (for images composed of
1.89 +pixels) generic paint programs or (for drawings) some widely available
1.90 +drawing editor, and that is suitable for input to text formatters or
1.91 +for automatic translation to a variety of formats suitable for input
1.92 +to text formatters. A copy made in an otherwise Transparent file
1.93 +format whose markup, or absence of markup, has been arranged to thwart
1.94 +or discourage subsequent modification by readers is not Transparent.
1.95 +An image format is not Transparent if used for any substantial amount
1.96 +of text. A copy that is not ``Transparent'' is called ``Opaque''.
1.97 +
1.98 +Examples of suitable formats for Transparent copies include plain
1.99 +@sc{ascii} without markup, Texinfo input format, La@TeX{} input
1.100 +format, @acronym{SGML} or @acronym{XML} using a publicly available
1.101 +@acronym{DTD}, and standard-conforming simple @acronym{HTML},
1.102 +PostScript or @acronym{PDF} designed for human modification. Examples
1.103 +of transparent image formats include @acronym{PNG}, @acronym{XCF} and
1.104 +@acronym{JPG}. Opaque formats include proprietary formats that can be
1.105 +read and edited only by proprietary word processors, @acronym{SGML} or
1.106 +@acronym{XML} for which the @acronym{DTD} and/or processing tools are
1.107 +not generally available, and the machine-generated @acronym{HTML},
1.108 +PostScript or @acronym{PDF} produced by some word processors for
1.109 +output purposes only.
1.110 +
1.111 +The ``Title Page'' means, for a printed book, the title page itself,
1.112 +plus such following pages as are needed to hold, legibly, the material
1.113 +this License requires to appear in the title page. For works in
1.114 +formats which do not have any title page as such, ``Title Page'' means
1.115 +the text near the most prominent appearance of the work's title,
1.116 +preceding the beginning of the body of the text.
1.117 +
1.118 +A section ``Entitled XYZ'' means a named subunit of the Document whose
1.119 +title either is precisely XYZ or contains XYZ in parentheses following
1.120 +text that translates XYZ in another language. (Here XYZ stands for a
1.121 +specific section name mentioned below, such as ``Acknowledgements'',
1.122 +``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title''
1.123 +of such a section when you modify the Document means that it remains a
1.124 +section ``Entitled XYZ'' according to this definition.
1.125 +
1.126 +The Document may include Warranty Disclaimers next to the notice which
1.127 +states that this License applies to the Document. These Warranty
1.128 +Disclaimers are considered to be included by reference in this
1.129 +License, but only as regards disclaiming warranties: any other
1.130 +implication that these Warranty Disclaimers may have is void and has
1.131 +no effect on the meaning of this License.
1.132 +
1.133 +@item
1.134 +VERBATIM COPYING
1.135 +
1.136 +You may copy and distribute the Document in any medium, either
1.137 +commercially or noncommercially, provided that this License, the
1.138 +copyright notices, and the license notice saying this License applies
1.139 +to the Document are reproduced in all copies, and that you add no other
1.140 +conditions whatsoever to those of this License. You may not use
1.141 +technical measures to obstruct or control the reading or further
1.142 +copying of the copies you make or distribute. However, you may accept
1.143 +compensation in exchange for copies. If you distribute a large enough
1.144 +number of copies you must also follow the conditions in section 3.
1.145 +
1.146 +You may also lend copies, under the same conditions stated above, and
1.147 +you may publicly display copies.
1.148 +
1.149 +@item
1.150 +COPYING IN QUANTITY
1.151 +
1.152 +If you publish printed copies (or copies in media that commonly have
1.153 +printed covers) of the Document, numbering more than 100, and the
1.154 +Document's license notice requires Cover Texts, you must enclose the
1.155 +copies in covers that carry, clearly and legibly, all these Cover
1.156 +Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
1.157 +the back cover. Both covers must also clearly and legibly identify
1.158 +you as the publisher of these copies. The front cover must present
1.159 +the full title with all words of the title equally prominent and
1.160 +visible. You may add other material on the covers in addition.
1.161 +Copying with changes limited to the covers, as long as they preserve
1.162 +the title of the Document and satisfy these conditions, can be treated
1.163 +as verbatim copying in other respects.
1.164 +
1.165 +If the required texts for either cover are too voluminous to fit
1.166 +legibly, you should put the first ones listed (as many as fit
1.167 +reasonably) on the actual cover, and continue the rest onto adjacent
1.168 +pages.
1.169 +
1.170 +If you publish or distribute Opaque copies of the Document numbering
1.171 +more than 100, you must either include a machine-readable Transparent
1.172 +copy along with each Opaque copy, or state in or with each Opaque copy
1.173 +a computer-network location from which the general network-using
1.174 +public has access to download using public-standard network protocols
1.175 +a complete Transparent copy of the Document, free of added material.
1.176 +If you use the latter option, you must take reasonably prudent steps,
1.177 +when you begin distribution of Opaque copies in quantity, to ensure
1.178 +that this Transparent copy will remain thus accessible at the stated
1.179 +location until at least one year after the last time you distribute an
1.180 +Opaque copy (directly or through your agents or retailers) of that
1.181 +edition to the public.
1.182 +
1.183 +It is requested, but not required, that you contact the authors of the
1.184 +Document well before redistributing any large number of copies, to give
1.185 +them a chance to provide you with an updated version of the Document.
1.186 +
1.187 +@item
1.188 +MODIFICATIONS
1.189 +
1.190 +You may copy and distribute a Modified Version of the Document under
1.191 +the conditions of sections 2 and 3 above, provided that you release
1.192 +the Modified Version under precisely this License, with the Modified
1.193 +Version filling the role of the Document, thus licensing distribution
1.194 +and modification of the Modified Version to whoever possesses a copy
1.195 +of it. In addition, you must do these things in the Modified Version:
1.196 +
1.197 +@enumerate A
1.198 +@item
1.199 +Use in the Title Page (and on the covers, if any) a title distinct
1.200 +from that of the Document, and from those of previous versions
1.201 +(which should, if there were any, be listed in the History section
1.202 +of the Document). You may use the same title as a previous version
1.203 +if the original publisher of that version gives permission.
1.204 +
1.205 +@item
1.206 +List on the Title Page, as authors, one or more persons or entities
1.207 +responsible for authorship of the modifications in the Modified
1.208 +Version, together with at least five of the principal authors of the
1.209 +Document (all of its principal authors, if it has fewer than five),
1.210 +unless they release you from this requirement.
1.211 +
1.212 +@item
1.213 +State on the Title page the name of the publisher of the
1.214 +Modified Version, as the publisher.
1.215 +
1.216 +@item
1.217 +Preserve all the copyright notices of the Document.
1.218 +
1.219 +@item
1.220 +Add an appropriate copyright notice for your modifications
1.221 +adjacent to the other copyright notices.
1.222 +
1.223 +@item
1.224 +Include, immediately after the copyright notices, a license notice
1.225 +giving the public permission to use the Modified Version under the
1.226 +terms of this License, in the form shown in the Addendum below.
1.227 +
1.228 +@item
1.229 +Preserve in that license notice the full lists of Invariant Sections
1.230 +and required Cover Texts given in the Document's license notice.
1.231 +
1.232 +@item
1.233 +Include an unaltered copy of this License.
1.234 +
1.235 +@item
1.236 +Preserve the section Entitled ``History'', Preserve its Title, and add
1.237 +to it an item stating at least the title, year, new authors, and
1.238 +publisher of the Modified Version as given on the Title Page. If
1.239 +there is no section Entitled ``History'' in the Document, create one
1.240 +stating the title, year, authors, and publisher of the Document as
1.241 +given on its Title Page, then add an item describing the Modified
1.242 +Version as stated in the previous sentence.
1.243 +
1.244 +@item
1.245 +Preserve the network location, if any, given in the Document for
1.246 +public access to a Transparent copy of the Document, and likewise
1.247 +the network locations given in the Document for previous versions
1.248 +it was based on. These may be placed in the ``History'' section.
1.249 +You may omit a network location for a work that was published at
1.250 +least four years before the Document itself, or if the original
1.251 +publisher of the version it refers to gives permission.
1.252 +
1.253 +@item
1.254 +For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
1.255 +the Title of the section, and preserve in the section all the
1.256 +substance and tone of each of the contributor acknowledgements and/or
1.257 +dedications given therein.
1.258 +
1.259 +@item
1.260 +Preserve all the Invariant Sections of the Document,
1.261 +unaltered in their text and in their titles. Section numbers
1.262 +or the equivalent are not considered part of the section titles.
1.263 +
1.264 +@item
1.265 +Delete any section Entitled ``Endorsements''. Such a section
1.266 +may not be included in the Modified Version.
1.267 +
1.268 +@item
1.269 +Do not retitle any existing section to be Entitled ``Endorsements'' or
1.270 +to conflict in title with any Invariant Section.
1.271 +
1.272 +@item
1.273 +Preserve any Warranty Disclaimers.
1.274 +@end enumerate
1.275 +
1.276 +If the Modified Version includes new front-matter sections or
1.277 +appendices that qualify as Secondary Sections and contain no material
1.278 +copied from the Document, you may at your option designate some or all
1.279 +of these sections as invariant. To do this, add their titles to the
1.280 +list of Invariant Sections in the Modified Version's license notice.
1.281 +These titles must be distinct from any other section titles.
1.282 +
1.283 +You may add a section Entitled ``Endorsements'', provided it contains
1.284 +nothing but endorsements of your Modified Version by various
1.285 +parties---for example, statements of peer review or that the text has
1.286 +been approved by an organization as the authoritative definition of a
1.287 +standard.
1.288 +
1.289 +You may add a passage of up to five words as a Front-Cover Text, and a
1.290 +passage of up to 25 words as a Back-Cover Text, to the end of the list
1.291 +of Cover Texts in the Modified Version. Only one passage of
1.292 +Front-Cover Text and one of Back-Cover Text may be added by (or
1.293 +through arrangements made by) any one entity. If the Document already
1.294 +includes a cover text for the same cover, previously added by you or
1.295 +by arrangement made by the same entity you are acting on behalf of,
1.296 +you may not add another; but you may replace the old one, on explicit
1.297 +permission from the previous publisher that added the old one.
1.298 +
1.299 +The author(s) and publisher(s) of the Document do not by this License
1.300 +give permission to use their names for publicity for or to assert or
1.301 +imply endorsement of any Modified Version.
1.302 +
1.303 +@item
1.304 +COMBINING DOCUMENTS
1.305 +
1.306 +You may combine the Document with other documents released under this
1.307 +License, under the terms defined in section 4 above for modified
1.308 +versions, provided that you include in the combination all of the
1.309 +Invariant Sections of all of the original documents, unmodified, and
1.310 +list them all as Invariant Sections of your combined work in its
1.311 +license notice, and that you preserve all their Warranty Disclaimers.
1.312 +
1.313 +The combined work need only contain one copy of this License, and
1.314 +multiple identical Invariant Sections may be replaced with a single
1.315 +copy. If there are multiple Invariant Sections with the same name but
1.316 +different contents, make the title of each such section unique by
1.317 +adding at the end of it, in parentheses, the name of the original
1.318 +author or publisher of that section if known, or else a unique number.
1.319 +Make the same adjustment to the section titles in the list of
1.320 +Invariant Sections in the license notice of the combined work.
1.321 +
1.322 +In the combination, you must combine any sections Entitled ``History''
1.323 +in the various original documents, forming one section Entitled
1.324 +``History''; likewise combine any sections Entitled ``Acknowledgements'',
1.325 +and any sections Entitled ``Dedications''. You must delete all
1.326 +sections Entitled ``Endorsements.''
1.327 +
1.328 +@item
1.329 +COLLECTIONS OF DOCUMENTS
1.330 +
1.331 +You may make a collection consisting of the Document and other documents
1.332 +released under this License, and replace the individual copies of this
1.333 +License in the various documents with a single copy that is included in
1.334 +the collection, provided that you follow the rules of this License for
1.335 +verbatim copying of each of the documents in all other respects.
1.336 +
1.337 +You may extract a single document from such a collection, and distribute
1.338 +it individually under this License, provided you insert a copy of this
1.339 +License into the extracted document, and follow this License in all
1.340 +other respects regarding verbatim copying of that document.
1.341 +
1.342 +@item
1.343 +AGGREGATION WITH INDEPENDENT WORKS
1.344 +
1.345 +A compilation of the Document or its derivatives with other separate
1.346 +and independent documents or works, in or on a volume of a storage or
1.347 +distribution medium, is called an ``aggregate'' if the copyright
1.348 +resulting from the compilation is not used to limit the legal rights
1.349 +of the compilation's users beyond what the individual works permit.
1.350 +When the Document is included in an aggregate, this License does not
1.351 +apply to the other works in the aggregate which are not themselves
1.352 +derivative works of the Document.
1.353 +
1.354 +If the Cover Text requirement of section 3 is applicable to these
1.355 +copies of the Document, then if the Document is less than one half of
1.356 +the entire aggregate, the Document's Cover Texts may be placed on
1.357 +covers that bracket the Document within the aggregate, or the
1.358 +electronic equivalent of covers if the Document is in electronic form.
1.359 +Otherwise they must appear on printed covers that bracket the whole
1.360 +aggregate.
1.361 +
1.362 +@item
1.363 +TRANSLATION
1.364 +
1.365 +Translation is considered a kind of modification, so you may
1.366 +distribute translations of the Document under the terms of section 4.
1.367 +Replacing Invariant Sections with translations requires special
1.368 +permission from their copyright holders, but you may include
1.369 +translations of some or all Invariant Sections in addition to the
1.370 +original versions of these Invariant Sections. You may include a
1.371 +translation of this License, and all the license notices in the
1.372 +Document, and any Warranty Disclaimers, provided that you also include
1.373 +the original English version of this License and the original versions
1.374 +of those notices and disclaimers. In case of a disagreement between
1.375 +the translation and the original version of this License or a notice
1.376 +or disclaimer, the original version will prevail.
1.377 +
1.378 +If a section in the Document is Entitled ``Acknowledgements'',
1.379 +``Dedications'', or ``History'', the requirement (section 4) to Preserve
1.380 +its Title (section 1) will typically require changing the actual
1.381 +title.
1.382 +
1.383 +@item
1.384 +TERMINATION
1.385 +
1.386 +You may not copy, modify, sublicense, or distribute the Document except
1.387 +as expressly provided for under this License. Any other attempt to
1.388 +copy, modify, sublicense or distribute the Document is void, and will
1.389 +automatically terminate your rights under this License. However,
1.390 +parties who have received copies, or rights, from you under this
1.391 +License will not have their licenses terminated so long as such
1.392 +parties remain in full compliance.
1.393 +
1.394 +@item
1.395 +FUTURE REVISIONS OF THIS LICENSE
1.396 +
1.397 +The Free Software Foundation may publish new, revised versions
1.398 +of the GNU Free Documentation License from time to time. Such new
1.399 +versions will be similar in spirit to the present version, but may
1.400 +differ in detail to address new problems or concerns. See
1.401 +@uref{http://www.gnu.org/copyleft/}.
1.402 +
1.403 +Each version of the License is given a distinguishing version number.
1.404 +If the Document specifies that a particular numbered version of this
1.405 +License ``or any later version'' applies to it, you have the option of
1.406 +following the terms and conditions either of that specified version or
1.407 +of any later version that has been published (not as a draft) by the
1.408 +Free Software Foundation. If the Document does not specify a version
1.409 +number of this License, you may choose any version ever published (not
1.410 +as a draft) by the Free Software Foundation.
