   10: 59 Temple Place, Suite 330, Boston, MA  02111-1307, USA
   12: Everyone is permitted to copy and distribute verbatim copies
   13: of this license document, but changing it is not allowed.
   14: @end display
   16: @enumerate 0
   17: @item
   20: The purpose of this License is to make a manual, textbook, or other
   21: functional and useful document @dfn{free} in the sense of freedom: to
   22: assure everyone the effective freedom to copy and redistribute it,
   23: with or without modifying it, either commercially or noncommercially.
   24: Secondarily, this License preserves for the author and publisher a way
   25: to get credit for their work, while not being considered responsible
   26: for modifications made by others.
   28: This License is a kind of ``copyleft'', which means that derivative
   29: works of the document must themselves be free in the same sense.  It
   30: complements the GNU General Public License, which is a copyleft
   31: license designed for free software.
   33: We have designed this License in order to use it for manuals for free
   34: software, because free software needs free documentation: a free
   35: program should come with manuals providing the same freedoms that the
   36: software does.  But this License is not limited to software manuals;
   37: it can be used for any textual work, regardless of subject matter or
   38: whether it is published as a printed book.  We recommend this License
   39: principally for works whose purpose is instruction or reference.
   41: @item
   44: This License applies to any manual or other work, in any medium, that
   45: contains a notice placed by the copyright holder saying it can be
   46: distributed under the terms of this License.  Such a notice grants a
   47: world-wide, royalty-free license, unlimited in duration, to use that
   48: work under the conditions stated herein.  The ``Document'', below,
   49: refers to any such manual or work.  Any member of the public is a
   50: licensee, and is addressed as ``you''.  You accept the license if you
   51: copy, modify or distribute the work in a way requiring permission
   52: under copyright law.
   54: A ``Modified Version'' of the Document means any work containing the
   55: Document or a portion of it, either copied verbatim, or with
   56: modifications and/or translated into another language.
   58: A ``Secondary Section'' is a named appendix or a front-matter section
   59: of the Document that deals exclusively with the relationship of the
   60: publishers or authors of the Document to the Document's overall
   61: subject (or to related matters) and contains nothing that could fall
   62: directly within that overall subject.  (Thus, if the Document is in
   63: part a textbook of mathematics, a Secondary Section may not explain
   64: any mathematics.)  The relationship could be a matter of historical
   65: connection with the subject or with related matters, or of legal,
   66: commercial, philosophical, ethical or political position regarding
   67: them.
   69: The ``Invariant Sections'' are certain Secondary Sections whose titles
   70: are designated, as being those of Invariant Sections, in the notice
   71: that says that the Document is released under this License.  If a
   72: section does not fit the above definition of Secondary then it is not
   73: allowed to be designated as Invariant.  The Document may contain zero
   74: Invariant Sections.  If the Document does not identify any Invariant
   75: Sections then there are none.
   77: The ``Cover Texts'' are certain short passages of text that are listed,
   78: as Front-Cover Texts or Back-Cover Texts, in the notice that says that
   79: the Document is released under this License.  A Front-Cover Text may
   80: be at most 5 words, and a Back-Cover Text may be at most 25 words.
   82: A ``Transparent'' copy of the Document means a machine-readable copy,
   83: represented in a format whose specification is available to the
   84: general public, that is suitable for revising the document
   85: straightforwardly with generic text editors or (for images composed of
   86: pixels) generic paint programs or (for drawings) some widely available
   87: drawing editor, and that is suitable for input to text formatters or
   88: for automatic translation to a variety of formats suitable for input
   89: to text formatters.  A copy made in an otherwise Transparent file
   90: format whose markup, or absence of markup, has been arranged to thwart
   91: or discourage subsequent modification by readers is not Transparent.
   92: An image format is not Transparent if used for any substantial amount
   93: of text.  A copy that is not ``Transparent'' is called ``Opaque''.
   95: Examples of suitable formats for Transparent copies include plain
   96: @sc{ascii} without markup, Texinfo input format, La@TeX{} input
   97: format, @acronym{SGML} or @acronym{XML} using a publicly available
   98: @acronym{DTD}, and standard-conforming simple @acronym{HTML},
   99: PostScript or @acronym{PDF} designed for human modification.  Examples
  100: of transparent image formats include @acronym{PNG}, @acronym{XCF} and
  101: @acronym{JPG}.  Opaque formats include proprietary formats that can be
  102: read and edited only by proprietary word processors, @acronym{SGML} or
  103: @acronym{XML} for which the @acronym{DTD} and/or processing tools are
  104: not generally available, and the machine-generated @acronym{HTML},
  105: PostScript or @acronym{PDF} produced by some word processors for
  106: output purposes only.
  108: The ``Title Page'' means, for a printed book, the title page itself,
  109: plus such following pages as are needed to hold, legibly, the material
  110: this License requires to appear in the title page.  For works in
  111: formats which do not have any title page as such, ``Title Page'' means
  112: the text near the most prominent appearance of the work's title,
  113: preceding the beginning of the body of the text.
  115: A section ``Entitled XYZ'' means a named subunit of the Document whose
  116: title either is precisely XYZ or contains XYZ in parentheses following
  117: text that translates XYZ in another language.  (Here XYZ stands for a
  118: specific section name mentioned below, such as ``Acknowledgements'',
  119: ``Dedications'', ``Endorsements'', or ``History''.)  To ``Preserve the Title''
  120: of such a section when you modify the Document means that it remains a
  121: section ``Entitled XYZ'' according to this definition.
  123: The Document may include Warranty Disclaimers next to the notice which
  124: states that this License applies to the Document.  These Warranty
  125: Disclaimers are considered to be included by reference in this
  126: License, but only as regards disclaiming warranties: any other
  127: implication that these Warranty Disclaimers may have is void and has
  128: no effect on the meaning of this License.
  130: @item
  133: You may copy and distribute the Document in any medium, either
  134: commercially or noncommercially, provided that this License, the
  135: copyright notices, and the license notice saying this License applies
  136: to the Document are reproduced in all copies, and that you add no other
  137: conditions whatsoever to those of this License.  You may not use
  138: technical measures to obstruct or control the reading or further
  139: copying of the copies you make or distribute.  However, you may accept
  140: compensation in exchange for copies.  If you distribute a large enough
  141: number of copies you must also follow the conditions in section 3.
  143: You may also lend copies, under the same conditions stated above, and
  144: you may publicly display copies.
  146: @item
  149: If you publish printed copies (or copies in media that commonly have
  150: printed covers) of the Document, numbering more than 100, and the
  151: Document's license notice requires Cover Texts, you must enclose the
  152: copies in covers that carry, clearly and legibly, all these Cover
  153: Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
  154: the back cover.  Both covers must also clearly and legibly identify
  155: you as the publisher of these copies.  The front cover must present
  156: the full title with all words of the title equally prominent and
  157: visible.  You may add other material on the covers in addition.
  158: Copying with changes limited to the covers, as long as they preserve
  159: the title of the Document and satisfy these conditions, can be treated
  160: as verbatim copying in other respects.
  162: If the required texts for either cover are too voluminous to fit
  163: legibly, you should put the first ones listed (as many as fit
  164: reasonably) on the actual cover, and continue the rest onto adjacent
  165: pages.
  167: If you publish or distribute Opaque copies of the Document numbering
  168: more than 100, you must either include a machine-readable Transparent
  169: copy along with each Opaque copy, or state in or with each Opaque copy
  170: a computer-network location from which the general network-using
  171: public has access to download using public-standard network protocols
  172: a complete Transparent copy of the Document, free of added material.
  173: If you use the latter option, you must take reasonably prudent steps,
  174: when you begin distribution of Opaque copies in quantity, to ensure
  175: that this Transparent copy will remain thus accessible at the stated
  176: location until at least one year after the last time you distribute an
  177: Opaque copy (directly or through your agents or retailers) of that
  178: edition to the public.
  180: It is requested, but not required, that you contact the authors of the
  181: Document well before redistributing any large number of copies, to give
  182: them a chance to provide you with an updated version of the Document.
  184: @item
  187: You may copy and distribute a Modified Version of the Document under
  188: the conditions of sections 2 and 3 above, provided that you release
  189: the Modified Version under precisely this License, with the Modified
  190: Version filling the role of the Document, thus licensing distribution
  191: and modification of the Modified Version to whoever possesses a copy
  192: of it.  In addition, you must do these things in the Modified Version:
  194: @enumerate A
  195: @item
  196: Use in the Title Page (and on the covers, if any) a title distinct
  197: from that of the Document, and from those of previous versions
  198: (which should, if there were any, be listed in the History section
  199: of the Document).  You may use the same title as a previous version
  200: if the original publisher of that version gives permission.
  202: @item
  203: List on the Title Page, as authors, one or more persons or entities
  204: responsible for authorship of the modifications in the Modified
  205: Version, together with at least five of the principal authors of the
  206: Document (all of its principal authors, if it has fewer than five),
  207: unless they release you from this requirement.
  209: @item
  210: State on the Title page the name of the publisher of the
  211: Modified Version, as the publisher.
  213: @item
  214: Preserve all the copyright notices of the Document.
  216: @item
  217: Add an appropriate copyright notice for your modifications
  218: adjacent to the other copyright notices.
  220: @item
  221: Include, immediately after the copyright notices, a license notice
  222: giving the public permission to use the Modified Version under the
  223: terms of this License, in the form shown in the Addendum below.
  225: @item
  226: Preserve in that license notice the full lists of Invariant Sections
  227: and required Cover Texts given in the Document's license notice.
  229: @item
  230: Include an unaltered copy of this License.
  232: @item
  233: Preserve the section Entitled ``History'', Preserve its Title, and add
  234: to it an item stating at least the title, year, new authors, and
  235: publisher of the Modified Version as given on the Title Page.  If
  236: there is no section Entitled ``History'' in the Document, create one
  237: stating the title, year, authors, and publisher of the Document as
  238: given on its Title Page, then add an item describing the Modified
  239: Version as stated in the previous sentence.
  241: @item
  242: Preserve the network location, if any, given in the Document for
  243: public access to a Transparent copy of the Document, and likewise
  244: the network locations given in the Document for previous versions
  245: it was based on.  These may be placed in the ``History'' section.
  246: You may omit a network location for a work that was published at
  247: least four years before the Document itself, or if the original
  248: publisher of the version it refers to gives permission.
  250: @item
  251: For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
  252: the Title of the section, and preserve in the section all the
  253: substance and tone of each of the contributor acknowledgements and/or
  254: dedications given therein.
  256: @item
  257: Preserve all the Invariant Sections of the Document,
  258: unaltered in their text and in their titles.  Section numbers
  259: or the equivalent are not considered part of the section titles.
  261: @item
  262: Delete any section Entitled ``Endorsements''.  Such a section
  263: may not be included in the Modified Version.
  265: @item
  266: Do not retitle any existing section to be Entitled ``Endorsements'' or
  267: to conflict in title with any Invariant Section.
  269: @item
  270: Preserve any Warranty Disclaimers.
  271: @end enumerate
  273: If the Modified Version includes new front-matter sections or
  274: appendices that qualify as Secondary Sections and contain no material
  275: copied from the Document, you may at your option designate some or all
  276: of these sections as invariant.  To do this, add their titles to the
  277: list of Invariant Sections in the Modified Version's license notice.
  278: These titles must be distinct from any other section titles.
  280: You may add a section Entitled ``Endorsements'', provided it contains
  281: nothing but endorsements of your Modified Version by various
  282: parties---for example, statements of peer review or that the text has
  283: been approved by an organization as the authoritative definition of a
  284: standard.
  286: You may add a passage of up to five words as a Front-Cover Text, and a
  287: passage of up to 25 words as a Back-Cover Text, to the end of the list
  288: of Cover Texts in the Modified Version.  Only one passage of
  289: Front-Cover Text and one of Back-Cover Text may be added by (or
  290: through arrangements made by) any one entity.  If the Document already
  291: includes a cover text for the same cover, previously added by you or
  292: by arrangement made by the same entity you are acting on behalf of,
  293: you may not add another; but you may replace the old one, on explicit
  294: permission from the previous publisher that added the old one.
  296: The author(s) and publisher(s) of the Document do not by this License
  297: give permission to use their names for publicity for or to assert or
  298: imply endorsement of any Modified Version.
  300: @item
  303: You may combine the Document with other documents released under this
  304: License, under the terms defined in section 4 above for modified
  305: versions, provided that you include in the combination all of the
  306: Invariant Sections of all of the original documents, unmodified, and
  307: list them all as Invariant Sections of your combined work in its
  308: license notice, and that you preserve all their Warranty Disclaimers.
  310: The combined work need only contain one copy of this License, and
  311: multiple identical Invariant Sections may be replaced with a single
  312: copy.  If there are multiple Invariant Sections with the same name but
  313: different contents, make the title of each such section unique by
  314: adding at the end of it, in parentheses, the name of the original
  315: author or publisher of that section if known, or else a unique number.
  316: Make the same adjustment to the section titles in the list of
  317: Invariant Sections in the license notice of the combined work.
  319: In the combination, you must combine any sections Entitled ``History''
  320: in the various original documents, forming one section Entitled
  321: ``History''; likewise combine any sections Entitled ``Acknowledgements'',
  322: and any sections Entitled ``Dedications''.  You must delete all
  323: sections Entitled ``Endorsements.''
  325: @item
  328: You may make a collection consisting of the Document and other documents
  329: released under this License, and replace the individual copies of this
  330: License in the various documents with a single copy that is included in
  331: the collection, provided that you follow the rules of this License for
  332: verbatim copying of each of the documents in all other respects.
  334: You may extract a single document from such a collection, and distribute
  335: it individually under this License, provided you insert a copy of this
  336: License into the extracted document, and follow this License in all
  337: other respects regarding verbatim copying of that document.
  339: @item
  342: A compilation of the Document or its derivatives with other separate
  343: and independent documents or works, in or on a volume of a storage or
  344: distribution medium, is called an ``aggregate'' if the copyright
  345: resulting from the compilation is not used to limit the legal rights
  346: of the compilation's users beyond what the individual works permit.
  347: When the Document is included in an aggregate, this License does not
  348: apply to the other works in the aggregate which are not themselves
  349: derivative works of the Document.
  351: If the Cover Text requirement of section 3 is applicable to these
  352: copies of the Document, then if the Document is less than one half of
  353: the entire aggregate, the Document's Cover Texts may be placed on
  354: covers that bracket the Document within the aggregate, or the
  355: electronic equivalent of covers if the Document is in electronic form.
  356: Otherwise they must appear on printed covers that bracket the whole
  357: aggregate.
  359: @item
  362: Translation is considered a kind of modification, so you may
  363: distribute translations of the Document under the terms of section 4.
  364: Replacing Invariant Sections with translations requires special
  365: permission from their copyright holders, but you may include
  366: translations of some or all Invariant Sections in addition to the
  367: original versions of these Invariant Sections.  You may include a
  368: translation of this License, and all the license notices in the
  369: Document, and any Warranty Disclaimers, provided that you also include
  370: the original English version of this License and the original versions
  371: of those notices and disclaimers.  In case of a disagreement between
  372: the translation and the original version of this License or a notice
  373: or disclaimer, the original version will prevail.
  375: If a section in the Document is Entitled ``Acknowledgements'',
  376: ``Dedications'', or ``History'', the requirement (section 4) to Preserve
  377: its Title (section 1) will typically require changing the actual
  378: title.
  380: @item
  383: You may not copy, modify, sublicense, or distribute the Document except
  384: as expressly provided for under this License.  Any other attempt to
  385: copy, modify, sublicense or distribute the Document is void, and will
  386: automatically terminate your rights under this License.  However,
  387: parties who have received copies, or rights, from you under this
  388: License will not have their licenses terminated so long as such
  389: parties remain in full compliance.
  391: @item
  394: The Free Software Foundation may publish new, revised versions
  395: of the GNU Free Documentation License from time to time.  Such new
  396: versions will be similar in spirit to the present version, but may
  397: differ in detail to address new problems or concerns.  See
  398: @uref{}.
  400: Each version of the License is given a distinguishing version number.
  401: If the Document specifies that a particular numbered version of this
  402: License ``or any later version'' applies to it, you have the option of
  403: following the terms and conditions either of that specified version or
  404: of any later version that has been published (not as a draft) by the
  405: Free Software Foundation.  If the Document does not specify a version
  406: number of this License, you may choose any version ever published (not
  407: as a draft) by the Free Software Foundation.

  411: @appendixsubsec ADDENDUM: How to use this License for your documents
  413: To use this License in a document you have written, include a copy of
  414: the License in the document and put the following copyright and
  415: license notices just after the title page:
  417: @smallexample
  418: @group
  419:   Copyright (C)  @var{year}  @var{your name}.
  420:   Permission is granted to copy, distribute and/or modify this document
  421:   under the terms of the GNU Free Documentation License, Version 1.2
  422:   or any later version published by the Free Software Foundation;
  423:   with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
  424:   Texts.  A copy of the license is included in the section entitled ``GNU
  425:   Free Documentation License''.
  426: @end group
  427: @end smallexample
  429: If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
  430: replace the ``with...Texts.'' line with this:
  432: @smallexample
  433: @group
  434:     with the Invariant Sections being @var{list their titles}, with
  435:     the Front-Cover Texts being @var{list}, and with the Back-Cover Texts
  436:     being @var{list}.
  437: @end group
  438: @end smallexample
  440: If you have Invariant Sections without Cover Texts, or some other
  441: combination of the three, merge those two alternatives to suit the
  442: situation.
  444: If your document contains nontrivial examples of program code, we
  445: recommend releasing these examples in parallel under your choice of
  446: free software license, such as the GNU General Public License,
  447: to permit their use in free software.
