    8: Everyone is permitted to copy and distribute verbatim copies
    9: of this license document, but changing it is not allowed.

   14: PREAMBLE
   15: 
   16: The purpose of this License is to make a manual, textbook, or other
   17: functional and useful document @dfn{free} in the sense of freedom: to
   18: assure everyone the effective freedom to copy and redistribute it,
   19: with or without modifying it, either commercially or noncommercially.
   20: Secondarily, this License preserves for the author and publisher a way
   21: to get credit for their work, while not being considered responsible
   22: for modifications made by others.
   23: 
   24: This License is a kind of ``copyleft'', which means that derivative
   25: works of the document must themselves be free in the same sense.  It
   26: complements the GNU General Public License, which is a copyleft
   27: license designed for free software.
   28: 
   29: We have designed this License in order to use it for manuals for free
   30: software, because free software needs free documentation: a free
   31: program should come with manuals providing the same freedoms that the
   32: software does.  But this License is not limited to software manuals;
   33: it can be used for any textual work, regardless of subject matter or
   34: whether it is published as a printed book.  We recommend this License
   35: principally for works whose purpose is instruction or reference.
   36: 
   37: @item
   38: APPLICABILITY AND DEFINITIONS
   39: 
   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: 
   50: A ``Modified Version'' of the Document means any work containing the
   51: Document or a portion of it, either copied verbatim, or with
   52: modifications and/or translated into another language.
   53: 
   54: A ``Secondary Section'' is a named appendix or a front-matter section
   55: of the Document that deals exclusively with the relationship of the
   56: publishers or authors of the Document to the Document's overall
   57: subject (or to related matters) and contains nothing that could fall
   58: directly within that overall subject.  (Thus, if the Document is in
   59: part a textbook of mathematics, a Secondary Section may not explain
   60: any mathematics.)  The relationship could be a matter of historical
   61: connection with the subject or with related matters, or of legal,
   62: commercial, philosophical, ethical or political position regarding
   63: them.
   64: 
   65: The ``Invariant Sections'' are certain Secondary Sections whose titles
   66: are designated, as being those of Invariant Sections, in the notice
   67: that says that the Document is released under this License.  If a
   68: section does not fit the above definition of Secondary then it is not
   69: allowed to be designated as Invariant.  The Document may contain zero
   70: Invariant Sections.  If the Document does not identify any Invariant
   71: Sections then there are none.
   72: 
   73: The ``Cover Texts'' are certain short passages of text that are listed,
   74: as Front-Cover Texts or Back-Cover Texts, in the notice that says that
   75: the Document is released under this License.  A Front-Cover Text may
   76: be at most 5 words, and a Back-Cover Text may be at most 25 words.
   77: 
   78: A ``Transparent'' copy of the Document means a machine-readable copy,
   79: represented in a format whose specification is available to the
   80: general public, that is suitable for revising the document
   81: straightforwardly with generic text editors or (for images composed of
   82: pixels) generic paint programs or (for drawings) some widely available
   83: drawing editor, and that is suitable for input to text formatters or
   84: for automatic translation to a variety of formats suitable for input
   85: to text formatters.  A copy made in an otherwise Transparent file
   86: format whose markup, or absence of markup, has been arranged to thwart
   87: or discourage subsequent modification by readers is not Transparent.
   88: An image format is not Transparent if used for any substantial amount
   89: of text.  A copy that is not ``Transparent'' is called ``Opaque''.
   90: 
   91: Examples of suitable formats for Transparent copies include plain
   92: @sc{ascii} without markup, Texinfo input format, La@TeX{} input
   93: format, @acronym{SGML} or @acronym{XML} using a publicly available
   94: @acronym{DTD}, and standard-conforming simple @acronym{HTML},
   95: PostScript or @acronym{PDF} designed for human modification.  Examples
   96: of transparent image formats include @acronym{PNG}, @acronym{XCF} and
   97: @acronym{JPG}.  Opaque formats include proprietary formats that can be
   98: read and edited only by proprietary word processors, @acronym{SGML} or
   99: @acronym{XML} for which the @acronym{DTD} and/or processing tools are
  100: not generally available, and the machine-generated @acronym{HTML},
  101: PostScript or @acronym{PDF} produced by some word processors for
  102: output purposes only.
  103: 
  104: The ``Title Page'' means, for a printed book, the title page itself,
  105: plus such following pages as are needed to hold, legibly, the material
  106: this License requires to appear in the title page.  For works in
  107: formats which do not have any title page as such, ``Title Page'' means
  108: the text near the most prominent appearance of the work's title,
  109: preceding the beginning of the body of the text.
  110: 
  111: A section ``Entitled XYZ'' means a named subunit of the Document whose
  112: title either is precisely XYZ or contains XYZ in parentheses following
  113: text that translates XYZ in another language.  (Here XYZ stands for a
  114: specific section name mentioned below, such as ``Acknowledgements'',
  115: ``Dedications'', ``Endorsements'', or ``History''.)  To ``Preserve the Title''
  116: of such a section when you modify the Document means that it remains a
  117: section ``Entitled XYZ'' according to this definition.
  118: 
  119: The Document may include Warranty Disclaimers next to the notice which
  120: states that this License applies to the Document.  These Warranty
  121: Disclaimers are considered to be included by reference in this
  122: License, but only as regards disclaiming warranties: any other
  123: implication that these Warranty Disclaimers may have is void and has
  124: no effect on the meaning of this License.
  125: 
  126: @item
  127: VERBATIM COPYING
  128: 
  129: You may copy and distribute the Document in any medium, either
  130: commercially or noncommercially, provided that this License, the
  131: copyright notices, and the license notice saying this License applies
  132: to the Document are reproduced in all copies, and that you add no other
  133: conditions whatsoever to those of this License.  You may not use
  134: technical measures to obstruct or control the reading or further
  135: copying of the copies you make or distribute.  However, you may accept
  136: compensation in exchange for copies.  If you distribute a large enough
  137: number of copies you must also follow the conditions in section 3.
  138: 
  139: You may also lend copies, under the same conditions stated above, and
  140: you may publicly display copies.
  141: 
  142: @item
  143: COPYING IN QUANTITY
  144: 
  145: If you publish printed copies (or copies in media that commonly have
  146: printed covers) of the Document, numbering more than 100, and the
  147: Document's license notice requires Cover Texts, you must enclose the
  148: copies in covers that carry, clearly and legibly, all these Cover
  149: Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
  150: the back cover.  Both covers must also clearly and legibly identify
  151: you as the publisher of these copies.  The front cover must present
  152: the full title with all words of the title equally prominent and
  153: visible.  You may add other material on the covers in addition.
  154: Copying with changes limited to the covers, as long as they preserve
  155: the title of the Document and satisfy these conditions, can be treated
  156: as verbatim copying in other respects.
  157: 
  158: If the required texts for either cover are too voluminous to fit
  159: legibly, you should put the first ones listed (as many as fit
  160: reasonably) on the actual cover, and continue the rest onto adjacent
  161: pages.
  162: 
  163: If you publish or distribute Opaque copies of the Document numbering
  164: more than 100, you must either include a machine-readable Transparent
  165: copy along with each Opaque copy, or state in or with each Opaque copy
  166: a computer-network location from which the general network-using
  167: public has access to download using public-standard network protocols
  168: a complete Transparent copy of the Document, free of added material.
  169: If you use the latter option, you must take reasonably prudent steps,
  170: when you begin distribution of Opaque copies in quantity, to ensure
  171: that this Transparent copy will remain thus accessible at the stated
  172: location until at least one year after the last time you distribute an
  173: Opaque copy (directly or through your agents or retailers) of that
  174: edition to the public.
  175: 
  176: It is requested, but not required, that you contact the authors of the
  177: Document well before redistributing any large number of copies, to give
  178: them a chance to provide you with an updated version of the Document.
  179: 
  180: @item
  181: MODIFICATIONS
  182: 
  183: You may copy and distribute a Modified Version of the Document under
  184: the conditions of sections 2 and 3 above, provided that you release
  185: the Modified Version under precisely this License, with the Modified
  186: Version filling the role of the Document, thus licensing distribution
  187: and modification of the Modified Version to whoever possesses a copy
  188: of it.  In addition, you must do these things in the Modified Version:
  189: 
  190: @enumerate A
  191: @item
  192: Use in the Title Page (and on the covers, if any) a title distinct
  193: from that of the Document, and from those of previous versions
  194: (which should, if there were any, be listed in the History section
  195: of the Document).  You may use the same title as a previous version
  196: if the original publisher of that version gives permission.
  197: 
  198: @item
  199: List on the Title Page, as authors, one or more persons or entities
  200: responsible for authorship of the modifications in the Modified
  201: Version, together with at least five of the principal authors of the
  202: Document (all of its principal authors, if it has fewer than five),
  203: unless they release you from this requirement.
  204: 
  205: @item
  206: State on the Title page the name of the publisher of the
  207: Modified Version, as the publisher.
  208: 
  209: @item
  210: Preserve all the copyright notices of the Document.
  211: 
  212: @item
  213: Add an appropriate copyright notice for your modifications
  214: adjacent to the other copyright notices.
  215: 
  216: @item
  217: Include, immediately after the copyright notices, a license notice
  218: giving the public permission to use the Modified Version under the
  219: terms of this License, in the form shown in the Addendum below.
  220: 
  221: @item
  222: Preserve in that license notice the full lists of Invariant Sections
  223: and required Cover Texts given in the Document's license notice.
  224: 
  225: @item
  226: Include an unaltered copy of this License.
  227: 
  228: @item
  229: Preserve the section Entitled ``History'', Preserve its Title, and add
  230: to it an item stating at least the title, year, new authors, and
  231: publisher of the Modified Version as given on the Title Page.  If
  232: there is no section Entitled ``History'' in the Document, create one
  233: stating the title, year, authors, and publisher of the Document as
  234: given on its Title Page, then add an item describing the Modified
  235: Version as stated in the previous sentence.
  236: 
  237: @item
  238: Preserve the network location, if any, given in the Document for
  239: public access to a Transparent copy of the Document, and likewise
  240: the network locations given in the Document for previous versions
  241: it was based on.  These may be placed in the ``History'' section.
  242: You may omit a network location for a work that was published at
  243: least four years before the Document itself, or if the original
  244: publisher of the version it refers to gives permission.
  245: 
  246: @item
  247: For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
  248: the Title of the section, and preserve in the section all the
  249: substance and tone of each of the contributor acknowledgements and/or
  250: dedications given therein.
  251: 
  252: @item
  253: Preserve all the Invariant Sections of the Document,
  254: unaltered in their text and in their titles.  Section numbers
  255: or the equivalent are not considered part of the section titles.
  256: 
  257: @item
  258: Delete any section Entitled ``Endorsements''.  Such a section
  259: may not be included in the Modified Version.
  260: 
  261: @item
  262: Do not retitle any existing section to be Entitled ``Endorsements'' or
  263: to conflict in title with any Invariant Section.
  264: 
  265: @item
  266: Preserve any Warranty Disclaimers.
  267: @end enumerate
  268: 
  269: If the Modified Version includes new front-matter sections or
  270: appendices that qualify as Secondary Sections and contain no material
  271: copied from the Document, you may at your option designate some or all
  272: of these sections as invariant.  To do this, add their titles to the
  273: list of Invariant Sections in the Modified Version's license notice.
  274: These titles must be distinct from any other section titles.
  275: 
  276: You may add a section Entitled ``Endorsements'', provided it contains
  277: nothing but endorsements of your Modified Version by various
  278: parties---for example, statements of peer review or that the text has
  279: been approved by an organization as the authoritative definition of a
  280: standard.
  281: 
  282: You may add a passage of up to five words as a Front-Cover Text, and a
  283: passage of up to 25 words as a Back-Cover Text, to the end of the list
  284: of Cover Texts in the Modified Version.  Only one passage of
  285: Front-Cover Text and one of Back-Cover Text may be added by (or
  286: through arrangements made by) any one entity.  If the Document already
  287: includes a cover text for the same cover, previously added by you or
  288: by arrangement made by the same entity you are acting on behalf of,
  289: you may not add another; but you may replace the old one, on explicit
  290: permission from the previous publisher that added the old one.
  291: 
  292: The author(s) and publisher(s) of the Document do not by this License
  293: give permission to use their names for publicity for or to assert or
  294: imply endorsement of any Modified Version.
  295: 
  296: @item
  297: COMBINING DOCUMENTS
  298: 
  299: You may combine the Document with other documents released under this
  300: License, under the terms defined in section 4 above for modified
  301: versions, provided that you include in the combination all of the
  302: Invariant Sections of all of the original documents, unmodified, and
  303: list them all as Invariant Sections of your combined work in its
  304: license notice, and that you preserve all their Warranty Disclaimers.
  305: 
  306: The combined work need only contain one copy of this License, and
  307: multiple identical Invariant Sections may be replaced with a single
  308: copy.  If there are multiple Invariant Sections with the same name but
  309: different contents, make the title of each such section unique by
  310: adding at the end of it, in parentheses, the name of the original
  311: author or publisher of that section if known, or else a unique number.
  312: Make the same adjustment to the section titles in the list of
  313: Invariant Sections in the license notice of the combined work.
  314: 
  315: In the combination, you must combine any sections Entitled ``History''
  316: in the various original documents, forming one section Entitled
  317: ``History''; likewise combine any sections Entitled ``Acknowledgements'',
  318: and any sections Entitled ``Dedications''.  You must delete all
  319: sections Entitled ``Endorsements.''
  320: 
  321: @item
  322: COLLECTIONS OF DOCUMENTS
  323: 
  324: You may make a collection consisting of the Document and other documents
  325: released under this License, and replace the individual copies of this
  326: License in the various documents with a single copy that is included in
  327: the collection, provided that you follow the rules of this License for
  328: verbatim copying of each of the documents in all other respects.
  329: 
  330: You may extract a single document from such a collection, and distribute
  331: it individually under this License, provided you insert a copy of this
  332: License into the extracted document, and follow this License in all
  333: other respects regarding verbatim copying of that document.
  334: 
  335: @item
  336: AGGREGATION WITH INDEPENDENT WORKS
  337: 
  338: A compilation of the Document or its derivatives with other separate
  339: and independent documents or works, in or on a volume of a storage or
  340: distribution medium, is called an ``aggregate'' if the copyright
  341: resulting from the compilation is not used to limit the legal rights
  342: of the compilation's users beyond what the individual works permit.
  343: When the Document is included in an aggregate, this License does not
  344: apply to the other works in the aggregate which are not themselves
  345: derivative works of the Document.
  346: 
  347: If the Cover Text requirement of section 3 is applicable to these
  348: copies of the Document, then if the Document is less than one half of
  349: the entire aggregate, the Document's Cover Texts may be placed on
  350: covers that bracket the Document within the aggregate, or the
  351: electronic equivalent of covers if the Document is in electronic form.
  352: Otherwise they must appear on printed covers that bracket the whole
  353: aggregate.
  354: 
  355: @item
  356: TRANSLATION
  357: 
  358: Translation is considered a kind of modification, so you may
  359: distribute translations of the Document under the terms of section 4.
  360: Replacing Invariant Sections with translations requires special
  361: permission from their copyright holders, but you may include
  362: translations of some or all Invariant Sections in addition to the
  363: original versions of these Invariant Sections.  You may include a
  364: translation of this License, and all the license notices in the
  365: Document, and any Warranty Disclaimers, provided that you also include
  366: the original English version of this License and the original versions
  367: of those notices and disclaimers.  In case of a disagreement between
  368: the translation and the original version of this License or a notice
  369: or disclaimer, the original version will prevail.
  370: 
  371: If a section in the Document is Entitled ``Acknowledgements'',
  372: ``Dedications'', or ``History'', the requirement (section 4) to Preserve
  373: its Title (section 1) will typically require changing the actual
  374: title.
  375: 
  376: @item
  377: TERMINATION
  378: 
  379: You may not copy, modify, sublicense, or distribute the Document except
  380: as expressly provided for under this License.  Any other attempt to
  381: copy, modify, sublicense or distribute the Document is void, and will
  382: automatically terminate your rights under this License.  However,
  383: parties who have received copies, or rights, from you under this
  384: License will not have their licenses terminated so long as such
  385: parties remain in full compliance.
  386: 
  387: @item
  388: FUTURE REVISIONS OF THIS LICENSE
  389: 
  390: The Free Software Foundation may publish new, revised versions
  391: of the GNU Free Documentation License from time to time.  Such new
  392: versions will be similar in spirit to the present version, but may
  393: differ in detail to address new problems or concerns.  See
  394: @uref{http://www.gnu.org/copyleft/}.
  395: 
  396: Each version of the License is given a distinguishing version number.
  397: If the Document specifies that a particular numbered version of this
  398: License ``or any later version'' applies to it, you have the option of
  399: following the terms and conditions either of that specified version or
  400: of any later version that has been published (not as a draft) by the
  401: Free Software Foundation.  If the Document does not specify a version
  402: number of this License, you may choose any version ever published (not
  403: as a draft) by the Free Software Foundation.

  440: If your document contains nontrivial examples of program code, we
  441: recommend releasing these examples in parallel under your choice of
  442: free software license, such as the GNU General Public License,
  443: to permit their use in free software.
