  66           </p>
  67
  68           <p>
  69             The purpose of this License is to make a manual, textbook, or other
  70             functional and useful document "free" in the sense of freedom: to
  71             assure everyone the effective freedom to copy and redistribute it,
  72             with or without modifying it, either commercially or noncommercially.
  73             Secondarily, this License preserves for the author and publisher a way
  74             to get credit for their work, while not being considered responsible
  75             for modifications made by others.
  76           </p>
  77
  78           <p>
  79             This License is a kind of "copyleft", which means that derivative
  80             works of the document must themselves be free in the same sense.  It
  81             complements the GNU General Public License, which is a copyleft
  82             license designed for free software.
  83           </p>
  84
  85           <p>
  86             We have designed this License in order to use it for manuals for free
  87             software, because free software needs free documentation: a free
  88             program should come with manuals providing the same freedoms that the
  89             software does.  But this License is not limited to software manuals;
  90             it can be used for any textual work, regardless of subject matter or
  91             whether it is published as a printed book.  We recommend this License
  92             principally for works whose purpose is instruction or reference.

  96             <h4>1. APPLICABILITY AND DEFINITIONS</h4>
  97           </p>
  98
  99           <p>
 100             This License applies to any manual or other work, in any medium, that
 101             contains a notice placed by the copyright holder saying it can be
 102             distributed under the terms of this License.  Such a notice grants a
 103             world-wide, royalty-free license, unlimited in duration, to use that
 104             work under the conditions stated herein.  The "Document", below,
 105             refers to any such manual or work.  Any member of the public is a
 106             licensee, and is addressed as "you".  You accept the license if you
 107             copy, modify or distribute the work in a way requiring permission
 108             under copyright law.
 109           </p>
 110
 111           <p>
 112             A "Modified Version" of the Document means any work containing the
 113             Document or a portion of it, either copied verbatim, or with
 114             modifications and/or translated into another language.
 115           </p>
 116
 117           <p>
 118             A "Secondary Section" is a named appendix or a front-matter section of
 119             the Document that deals exclusively with the relationship of the
 120             publishers or authors of the Document to the Document's overall subject
 121             (or to related matters) and contains nothing that could fall directly
 122             within that overall subject.  (Thus, if the Document is in part a
 123             textbook of mathematics, a Secondary Section may not explain any
 124             mathematics.)  The relationship could be a matter of historical
 125             connection with the subject or with related matters, or of legal,
 126             commercial, philosophical, ethical or political position regarding
 127             them.
 128           </p>
 129
 130           <p>
 131             The "Invariant Sections" are certain Secondary Sections whose titles
 132             are designated, as being those of Invariant Sections, in the notice
 133             that says that the Document is released under this License.  If a
 134             section does not fit the above definition of Secondary then it is not
 135             allowed to be designated as Invariant.  The Document may contain zero
 136             Invariant Sections.  If the Document does not identify any Invariant
 137             Sections then there are none.
 138           </p>
 139
 140           <p>
 141             The "Cover Texts" are certain short passages of text that are listed,
 142             as Front-Cover Texts or Back-Cover Texts, in the notice that says that
 143             the Document is released under this License.  A Front-Cover Text may
 144             be at most 5 words, and a Back-Cover Text may be at most 25 words.
 145           </p>
 146
 147           <p>
 148             A "Transparent" copy of the Document means a machine-readable copy,
 149             represented in a format whose specification is available to the
 150             general public, that is suitable for revising the document
 151             straightforwardly with generic text editors or (for images composed of
 152             pixels) generic paint programs or (for drawings) some widely available
 153             drawing editor, and that is suitable for input to text formatters or
 154             for automatic translation to a variety of formats suitable for input
 155             to text formatters.  A copy made in an otherwise Transparent file
 156             format whose markup, or absence of markup, has been arranged to thwart
 157             or discourage subsequent modification by readers is not Transparent.
 158             An image format is not Transparent if used for any substantial amount
 159             of text.  A copy that is not "Transparent" is called "Opaque".
 160           </p>
 161
 162           <p>
 163             Examples of suitable formats for Transparent copies include plain
 164             ASCII without markup, Texinfo input format, LaTeX input format, SGML
 165             or XML using a publicly available DTD, and standard-conforming simple
 166             HTML, PostScript or PDF designed for human modification.  Examples of
 167             transparent image formats include PNG, XCF and JPG.  Opaque formats
 168             include proprietary formats that can be read and edited only by
 169             proprietary word processors, SGML or XML for which the DTD and/or
 170             processing tools are not generally available, and the
 171             machine-generated HTML, PostScript or PDF produced by some word
 172             processors for output purposes only.
 173           </p>
 174
 175           <p>
 176             The "Title Page" means, for a printed book, the title page itself,
 177             plus such following pages as are needed to hold, legibly, the material
 178             this License requires to appear in the title page.  For works in
 179             formats which do not have any title page as such, "Title Page" means
 180             the text near the most prominent appearance of the work's title,
 181             preceding the beginning of the body of the text.
 182           </p>
 183
 184           <p>
 185             A section "Entitled XYZ" means a named subunit of the Document whose
 186             title either is precisely XYZ or contains XYZ in parentheses following
 187             text that translates XYZ in another language.  (Here XYZ stands for a
 188             specific section name mentioned below, such as "Acknowledgements",
 189             "Dedications", "Endorsements", or "History".)  To "Preserve the Title"
 190             of such a section when you modify the Document means that it remains a
 191             section "Entitled XYZ" according to this definition.
 192           </p>
 193
 194           <p>
 195             The Document may include Warranty Disclaimers next to the notice which
 196             states that this License applies to the Document.  These Warranty
 197             Disclaimers are considered to be included by reference in this
 198             License, but only as regards disclaiming warranties: any other
 199             implication that these Warranty Disclaimers may have is void and has
 200             no effect on the meaning of this License.
 201           </p>
 202
 203           <p>
 204             <h4>2. VERBATIM COPYING</h4>
 205           </p>
 206
 207           <p>
 208             You may copy and distribute the Document in any medium, either
 209             commercially or noncommercially, provided that this License, the
 210             copyright notices, and the license notice saying this License applies
 211             to the Document are reproduced in all copies, and that you add no other
 212             conditions whatsoever to those of this License.  You may not use
 213             technical measures to obstruct or control the reading or further
 214             copying of the copies you make or distribute.  However, you may accept
 215             compensation in exchange for copies.  If you distribute a large enough
 216             number of copies you must also follow the conditions in section 3.
 217           </p>
 218
 219           <p>
 220             You may also lend copies, under the same conditions stated above, and
 221             you may publicly display copies.
 222           </p>
 223
 224           <p>
 225             <h4>3. COPYING IN QUANTITY</h4>
 226           </p>
 227
 228           <p>
 229             If you publish printed copies (or copies in media that commonly have
 230             printed covers) of the Document, numbering more than 100, and the
 231             Document's license notice requires Cover Texts, you must enclose the
 232             copies in covers that carry, clearly and legibly, all these Cover
 233             Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
 234             the back cover.  Both covers must also clearly and legibly identify
 235             you as the publisher of these copies.  The front cover must present
 236             the full title with all words of the title equally prominent and
 237             visible.  You may add other material on the covers in addition.
 238             Copying with changes limited to the covers, as long as they preserve
 239             the title of the Document and satisfy these conditions, can be treated
 240             as verbatim copying in other respects.
 241           </p>
 242
 243           <p>
 244             If the required texts for either cover are too voluminous to fit
 245             legibly, you should put the first ones listed (as many as fit
 246             reasonably) on the actual cover, and continue the rest onto adjacent
 247             pages.
 248           </p>
 249
 250           <p>
 251             If you publish or distribute Opaque copies of the Document numbering
 252             more than 100, you must either include a machine-readable Transparent
 253             copy along with each Opaque copy, or state in or with each Opaque copy
 254             a computer-network location from which the general network-using
 255             public has access to download using public-standard network protocols
 256             a complete Transparent copy of the Document, free of added material.
 257             If you use the latter option, you must take reasonably prudent steps,
 258             when you begin distribution of Opaque copies in quantity, to ensure
 259             that this Transparent copy will remain thus accessible at the stated
 260             location until at least one year after the last time you distribute an
 261             Opaque copy (directly or through your agents or retailers) of that
 262             edition to the public.
 263           </p>
 264
 265           <p>
 266             It is requested, but not required, that you contact the authors of the
 267             Document well before redistributing any large number of copies, to give
 268             them a chance to provide you with an updated version of the Document.
 269           </p>
 270
 271           <p>
 272             <h4>4. MODIFICATIONS</h4>
 273           </p>
 274
 275           <p>
 276             You may copy and distribute a Modified Version of the Document under
 277             the conditions of sections 2 and 3 above, provided that you release
 278             the Modified Version under precisely this License, with the Modified
 279             Version filling the role of the Document, thus licensing distribution
 280             and modification of the Modified Version to whoever possesses a copy
 281             of it.  In addition, you must do these things in the Modified Version:
 282           </p>
 283
 284           <ul>
 285             <li><h4>A.</h4> Use in the Title Page (and on the covers, if any) a title distinct
 286               from that of the Document, and from those of previous versions
 287               (which should, if there were any, be listed in the History section
 288               of the Document).  You may use the same title as a previous version
 289               if the original publisher of that version gives permission.</li>
 290             <li><h4>B.</h4> List on the Title Page, as authors, one or more persons or entities
 291               responsible for authorship of the modifications in the Modified
 292               Version, together with at least five of the principal authors of the
 293               Document (all of its principal authors, if it has fewer than five),
 294               unless they release you from this requirement.</li>
 295             <li><h4>C.</h4> State on the Title page the name of the publisher of the
 296               Modified Version, as the publisher.</li>
 297             <li><h4>D.</h4> Preserve all the copyright notices of the Document.</li>
 298             <li><h4>E.</h4> Add an appropriate copyright notice for your modifications
 299               adjacent to the other copyright notices.</li>
 300             <li><h4>F.</h4> Include, immediately after the copyright notices, a license notice
 301               giving the public permission to use the Modified Version under the
 302               terms of this License, in the form shown in the Addendum below.</li>
 303             <li><h4>G.</h4> Preserve in that license notice the full lists of Invariant Sections
 304               and required Cover Texts given in the Document's license notice.</li>
 305             <li><h4>H.</h4> Include an unaltered copy of this License.</li>
 306             <li><h4>I.</h4> Preserve the section Entitled "History", Preserve its Title, and add
 307               to it an item stating at least the title, year, new authors, and
 308               publisher of the Modified Version as given on the Title Page.  If
 309               there is no section Entitled "History" in the Document, create one
 310               stating the title, year, authors, and publisher of the Document as
 311               given on its Title Page, then add an item describing the Modified
 312               Version as stated in the previous sentence.</li>
 313             <li><h4>J.</h4> Preserve the network location, if any, given in the Document for

 315               the network locations given in the Document for previous versions
 316               it was based on.  These may be placed in the "History" section.
 317               You may omit a network location for a work that was published at
 318               least four years before the Document itself, or if the original
 319               publisher of the version it refers to gives permission.</li>
 320             <li><h4>K.</h4> For any section Entitled "Acknowledgements" or "Dedications",
 321               Preserve the Title of the section, and preserve in the section all
 322               the substance and tone of each of the contributor acknowledgements
 323               and/or dedications given therein.</li>
 324             <li><h4>L.</h4> Preserve all the Invariant Sections of the Document,
 325               unaltered in their text and in their titles.  Section numbers
 326               or the equivalent are not considered part of the section titles.</li>
 327             <li><h4>M.</h4> Delete any section Entitled "Endorsements".  Such a section
 328               may not be included in the Modified Version.</li>
 329             <li><h4>N.</h4> Do not retitle any existing section to be Entitled "Endorsements"
 330               or to conflict in title with any Invariant Section.</li>
 331             <li><h4>O.</h4> Preserve any Warranty Disclaimers.</li>
 332           </ul>
 333
 334           <p>
 335             If the Modified Version includes new front-matter sections or
 336             appendices that qualify as Secondary Sections and contain no material
 337             copied from the Document, you may at your option designate some or all
 338             of these sections as invariant.  To do this, add their titles to the
 339             list of Invariant Sections in the Modified Version's license notice.
 340             These titles must be distinct from any other section titles.
 341           </p>
 342
 343           <p>
 344             You may add a section Entitled "Endorsements", provided it contains
 345             nothing but endorsements of your Modified Version by various
 346             parties--for example, statements of peer review or that the text has
 347             been approved by an organization as the authoritative definition of a
 348             standard.
 349           </p>
 350
 351           <p>
 352             You may add a passage of up to five words as a Front-Cover Text, and a
 353             passage of up to 25 words as a Back-Cover Text, to the end of the list
 354             of Cover Texts in the Modified Version.  Only one passage of
 355             Front-Cover Text and one of Back-Cover Text may be added by (or
 356             through arrangements made by) any one entity.  If the Document already
 357             includes a cover text for the same cover, previously added by you or
 358             by arrangement made by the same entity you are acting on behalf of,
 359             you may not add another; but you may replace the old one, on explicit
 360             permission from the previous publisher that added the old one.
 361           </p>
 362
 363           <p>
 364             The author(s) and publisher(s) of the Document do not by this License
 365             give permission to use their names for publicity for or to assert or
 366             imply endorsement of any Modified Version.

 371           </p>
 372
 373           <p>
 374             You may combine the Document with other documents released under this
 375             License, under the terms defined in section 4 above for modified
 376             versions, provided that you include in the combination all of the
 377             Invariant Sections of all of the original documents, unmodified, and
 378             list them all as Invariant Sections of your combined work in its
 379             license notice, and that you preserve all their Warranty Disclaimers.
 380           </p>
 381
 382           <p>
 383             The combined work need only contain one copy of this License, and
 384             multiple identical Invariant Sections may be replaced with a single
 385             copy.  If there are multiple Invariant Sections with the same name but
 386             different contents, make the title of each such section unique by
 387             adding at the end of it, in parentheses, the name of the original
 388             author or publisher of that section if known, or else a unique number.
 389             Make the same adjustment to the section titles in the list of
 390             Invariant Sections in the license notice of the combined work.
 391           </p>
 392
 393           <p>
 394             In the combination, you must combine any sections Entitled "History"
 395             in the various original documents, forming one section Entitled
 396             "History"; likewise combine any sections Entitled "Acknowledgements",
 397             and any sections Entitled "Dedications".  You must delete all sections
 398             Entitled "Endorsements."

 403           </p>
 404
 405           <p>
 406             You may make a collection consisting of the Document and other documents
 407             released under this License, and replace the individual copies of this
 408             License in the various documents with a single copy that is included in
 409             the collection, provided that you follow the rules of this License for
 410             verbatim copying of each of the documents in all other respects.
 411           </p>
 412
 413           <p>
 414             You may extract a single document from such a collection, and distribute
 415             it individually under this License, provided you insert a copy of this
 416             License into the extracted document, and follow this License in all
 417             other respects regarding verbatim copying of that document.

 421             <h4>7. AGGREGATION WITH INDEPENDENT WORKS</h4>
 422           </p>
 423
 424           <p>
 425             A compilation of the Document or its derivatives with other separate
 426             and independent documents or works, in or on a volume of a storage or
 427             distribution medium, is called an "aggregate" if the copyright
 428             resulting from the compilation is not used to limit the legal rights
 429             of the compilation's users beyond what the individual works permit.
 430             When the Document is included in an aggregate, this License does not
 431             apply to the other works in the aggregate which are not themselves
 432             derivative works of the Document.
 433           </p>
 434
 435           <p>
 436             If the Cover Text requirement of section 3 is applicable to these
 437             copies of the Document, then if the Document is less than one half of
 438             the entire aggregate, the Document's Cover Texts may be placed on
 439             covers that bracket the Document within the aggregate, or the
 440             electronic equivalent of covers if the Document is in electronic form.
 441             Otherwise they must appear on printed covers that bracket the whole
 442             aggregate.
 443           </p>
 444
 445           <p>
 446             <h4>8. TRANSLATION</h4>
 447           </p>
 448
 449           <p>
 450             Translation is considered a kind of modification, so you may
 451             distribute translations of the Document under the terms of section 4.
 452             Replacing Invariant Sections with translations requires special
 453             permission from their copyright holders, but you may include
 454             translations of some or all Invariant Sections in addition to the
 455             original versions of these Invariant Sections.  You may include a
 456             translation of this License, and all the license notices in the
 457             Document, and any Warranty Disclaimers, provided that you also include
 458             the original English version of this License and the original versions
 459             of those notices and disclaimers.  In case of a disagreement between
 460             the translation and the original version of this License or a notice
 461             or disclaimer, the original version will prevail.
 462           </p>
 463
 464           <p>
 465             If a section in the Document is Entitled "Acknowledgements",
 466             "Dedications", or "History", the requirement (section 4) to Preserve
 467             its Title (section 1) will typically require changing the actual
 468             title.

 474
 475           <p>
 476             You may not copy, modify, sublicense, or distribute the Document except
 477             as expressly provided for under this License.  Any other attempt to
 478             copy, modify, sublicense or distribute the Document is void, and will
 479             automatically terminate your rights under this License.  However,
 480             parties who have received copies, or rights, from you under this
 481             License will not have their licenses terminated so long as such
 482             parties remain in full compliance.

 491             of the GNU Free Documentation License from time to time.  Such new
 492             versions will be similar in spirit to the present version, but may

 498             Each version of the License is given a distinguishing version number.
 499             If the Document specifies that a particular numbered version of this
 500             License "or any later version" applies to it, you have the option of
 501             following the terms and conditions either of that specified version or
 502             of any later version that has been published (not as a draft) by the
 503             Free Software Foundation.  If the Document does not specify a version
 504             number of this License, you may choose any version ever published (not
 505             as a draft) by the Free Software Foundation.

 508           <h3>How to use this License for your documents</h3>
 509
 510           <p>
 511             To use this License in a document you have written, include a copy of
 512             the License in the document and put the following copyright and
 513             license notices just after the title page:
 514           </p>
 515
 516           <pre>Copyright (c)  YEAR  YOUR NAME.</pre>
 517           <pre>Permission is granted to copy, distribute and/or modify this document</pre>
 518           <pre>under the terms of the GNU Free Documentation License, Version 1.2</pre>
 519           <pre>or any later version published by the Free Software Foundation;</pre>
 520           <pre>with no Invariant Sections, no Front-Cover Texts, and no Back-Cover</pre>
 521           <pre>Texts.  A copy of the license is included in the section entitled "GNU</pre>
 522           <pre>Free Documentation License".</pre>
 523
 524           <p>
 525             If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
 526             replace the "with...Texts." line with this:
 527           </p>
 528
 529           <pre>with the Invariant Sections being LIST THEIR TITLES, with the</pre>
 530           <pre>Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.</pre>
 531
 532           <p>
 533             If you have Invariant Sections without Cover Texts, or some other
 534             combination of the three, merge those two alternatives to suit the
 535             situation.
