   17: PREAMBLE
   18: 
   19: The purpose of this License is to make a manual, textbook, or other
   20: written document @dfn{free} in the sense of freedom: to assure everyone
   21: the effective freedom to copy and redistribute it, with or without
   22: modifying it, either commercially or noncommercially.  Secondarily,
   23: this License preserves for the author and publisher a way to get
   24: credit for their work, while not being considered responsible for
   25: modifications made by others.
   26: 
   27: This License is a kind of ``copyleft'', which means that derivative
   28: works of the document must themselves be free in the same sense.  It
   29: complements the GNU General Public License, which is a copyleft
   30: license designed for free software.
   31: 
   32: We have designed this License in order to use it for manuals for free
   33: software, because free software needs free documentation: a free
   34: program should come with manuals providing the same freedoms that the
   35: software does.  But this License is not limited to software manuals;
   36: it can be used for any textual work, regardless of subject matter or
   37: whether it is published as a printed book.  We recommend this License
   38: principally for works whose purpose is instruction or reference.
   39: 
   40: @item
   41: APPLICABILITY AND DEFINITIONS
   42: 
   43: This License applies to any manual or other work that contains a
   44: notice placed by the copyright holder saying it can be distributed
   45: under the terms of this License.  The ``Document'', below, refers to any
   46: such manual or work.  Any member of the public is a licensee, and is
   47: addressed as ``you''.
   48: 
   49: A ``Modified Version'' of the Document means any work containing the
   50: Document or a portion of it, either copied verbatim, or with
   51: modifications and/or translated into another language.
   52: 
   53: A ``Secondary Section'' is a named appendix or a front-matter section of
   54: the Document that deals exclusively with the relationship of the
   55: publishers or authors of the Document to the Document's overall subject
   56: (or to related matters) and contains nothing that could fall directly
   57: within that overall subject.  (For example, if the Document is in part a
   58: textbook of mathematics, a Secondary Section may not explain any
   59: mathematics.)  The relationship could be a matter of historical
   60: connection with the subject or with related matters, or of legal,
   61: commercial, philosophical, ethical or political position regarding
   62: them.
   63: 
   64: The ``Invariant Sections'' are certain Secondary Sections whose titles
   65: are designated, as being those of Invariant Sections, in the notice
   66: that says that the Document is released under this License.
   67: 
   68: The ``Cover Texts'' are certain short passages of text that are listed,
   69: as Front-Cover Texts or Back-Cover Texts, in the notice that says that
   70: the Document is released under this License.
   71: 
   72: A ``Transparent'' copy of the Document means a machine-readable copy,
   73: represented in a format whose specification is available to the
   74: general public, whose contents can be viewed and edited directly and
   75: straightforwardly with generic text editors or (for images composed of
   76: pixels) generic paint programs or (for drawings) some widely available
   77: drawing editor, and that is suitable for input to text formatters or
   78: for automatic translation to a variety of formats suitable for input
   79: to text formatters.  A copy made in an otherwise Transparent file
   80: format whose markup has been designed to thwart or discourage
   81: subsequent modification by readers is not Transparent.  A copy that is
   82: not ``Transparent'' is called ``Opaque''.
   83: 
   84: Examples of suitable formats for Transparent copies include plain
   85: @sc{ascii} without markup, Texinfo input format, La@TeX{} input format,
   86: @acronym{SGML} or @acronym{XML} using a publicly available
   87: @acronym{DTD}, and standard-conforming simple @acronym{HTML} designed
   88: for human modification.  Opaque formats include PostScript,
   89: @acronym{PDF}, proprietary formats that can be read and edited only by
   90: proprietary word processors, @acronym{SGML} or @acronym{XML} for which
   91: the @acronym{DTD} and/or processing tools are not generally available,
   92: and the machine-generated @acronym{HTML} produced by some word
   93: processors for output purposes only.
   94: 
   95: The ``Title Page'' means, for a printed book, the title page itself,
   96: plus such following pages as are needed to hold, legibly, the material
   97: this License requires to appear in the title page.  For works in
   98: formats which do not have any title page as such, ``Title Page'' means
   99: the text near the most prominent appearance of the work's title,
  100: preceding the beginning of the body of the text.

  102: @item
  103: VERBATIM COPYING
  104: 
  105: You may copy and distribute the Document in any medium, either
  106: commercially or noncommercially, provided that this License, the
  107: copyright notices, and the license notice saying this License applies
  108: to the Document are reproduced in all copies, and that you add no other
  109: conditions whatsoever to those of this License.  You may not use
  110: technical measures to obstruct or control the reading or further
  111: copying of the copies you make or distribute.  However, you may accept
  112: compensation in exchange for copies.  If you distribute a large enough
  113: number of copies you must also follow the conditions in section 3.
  114: 
  115: You may also lend copies, under the same conditions stated above, and
  116: you may publicly display copies.
  117: 
  118: @item
  119: COPYING IN QUANTITY
  120: 
  121: If you publish printed copies of the Document numbering more than 100,
  122: and the Document's license notice requires Cover Texts, you must enclose
  123: the copies in covers that carry, clearly and legibly, all these Cover
  124: Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
  125: the back cover.  Both covers must also clearly and legibly identify
  126: you as the publisher of these copies.  The front cover must present
  127: the full title with all words of the title equally prominent and
  128: visible.  You may add other material on the covers in addition.
  129: Copying with changes limited to the covers, as long as they preserve
  130: the title of the Document and satisfy these conditions, can be treated
  131: as verbatim copying in other respects.
  132: 
  133: If the required texts for either cover are too voluminous to fit
  134: legibly, you should put the first ones listed (as many as fit
  135: reasonably) on the actual cover, and continue the rest onto adjacent
  136: pages.
  137: 
  138: If you publish or distribute Opaque copies of the Document numbering
  139: more than 100, you must either include a machine-readable Transparent
  140: copy along with each Opaque copy, or state in or with each Opaque copy
  141: a publicly-accessible computer-network location containing a complete
  142: Transparent copy of the Document, free of added material, which the
  143: general network-using public has access to download anonymously at no
  144: charge using public-standard network protocols.  If you use the latter
  145: option, you must take reasonably prudent steps, when you begin
  146: distribution of Opaque copies in quantity, to ensure that this
  147: Transparent copy will remain thus accessible at the stated location
  148: until at least one year after the last time you distribute an Opaque
  149: copy (directly or through your agents or retailers) of that edition to
  150: the public.
  151: 
  152: It is requested, but not required, that you contact the authors of the
  153: Document well before redistributing any large number of copies, to give
  154: them a chance to provide you with an updated version of the Document.
  155: 
  156: @item
  157: MODIFICATIONS
  158: 
  159: You may copy and distribute a Modified Version of the Document under
  160: the conditions of sections 2 and 3 above, provided that you release
  161: the Modified Version under precisely this License, with the Modified
  162: Version filling the role of the Document, thus licensing distribution
  163: and modification of the Modified Version to whoever possesses a copy
  164: of it.  In addition, you must do these things in the Modified Version:
  165: 
  166: @enumerate A
  167: @item
  168: Use in the Title Page (and on the covers, if any) a title distinct
  169: from that of the Document, and from those of previous versions
  170: (which should, if there were any, be listed in the History section
  171: of the Document).  You may use the same title as a previous version
  172: if the original publisher of that version gives permission.
  173: 
  174: @item
  175: List on the Title Page, as authors, one or more persons or entities
  176: responsible for authorship of the modifications in the Modified
  177: Version, together with at least five of the principal authors of the
  178: Document (all of its principal authors, if it has less than five).
  179: 
  180: @item
  181: State on the Title page the name of the publisher of the
  182: Modified Version, as the publisher.
  183: 
  184: @item
  185: Preserve all the copyright notices of the Document.
  186: 
  187: @item
  188: Add an appropriate copyright notice for your modifications
  189: adjacent to the other copyright notices.
  190: 
  191: @item
  192: Include, immediately after the copyright notices, a license notice
  193: giving the public permission to use the Modified Version under the
  194: terms of this License, in the form shown in the Addendum below.
  195: 
  196: @item
  197: Preserve in that license notice the full lists of Invariant Sections
  198: and required Cover Texts given in the Document's license notice.
  199: 
  200: @item
  201: Include an unaltered copy of this License.
  202: 
  203: @item
  204: Preserve the section entitled ``History'', and its title, and add to
  205: it an item stating at least the title, year, new authors, and
  206: publisher of the Modified Version as given on the Title Page.  If
  207: there is no section entitled ``History'' in the Document, create one
  208: stating the title, year, authors, and publisher of the Document as
  209: given on its Title Page, then add an item describing the Modified
  210: Version as stated in the previous sentence.
  211: 
  212: @item
  213: Preserve the network location, if any, given in the Document for
  214: public access to a Transparent copy of the Document, and likewise
  215: the network locations given in the Document for previous versions
  216: it was based on.  These may be placed in the ``History'' section.
  217: You may omit a network location for a work that was published at
  218: least four years before the Document itself, or if the original
  219: publisher of the version it refers to gives permission.
  220: 
  221: @item
  222: In any section entitled ``Acknowledgments'' or ``Dedications'',
  223: preserve the section's title, and preserve in the section all the
  224: substance and tone of each of the contributor acknowledgments
  225: and/or dedications given therein.
  226: 
  227: @item
  228: Preserve all the Invariant Sections of the Document,
  229: unaltered in their text and in their titles.  Section numbers
  230: or the equivalent are not considered part of the section titles.
  231: 
  232: @item
  233: Delete any section entitled ``Endorsements''.  Such a section
  234: may not be included in the Modified Version.
  235: 
  236: @item
  237: Do not retitle any existing section as ``Endorsements''
  238: or to conflict in title with any Invariant Section.
  239: @end enumerate
  240: 
  241: If the Modified Version includes new front-matter sections or
  242: appendices that qualify as Secondary Sections and contain no material
  243: copied from the Document, you may at your option designate some or all
  244: of these sections as invariant.  To do this, add their titles to the
  245: list of Invariant Sections in the Modified Version's license notice.
  246: These titles must be distinct from any other section titles.
  247: 
  248: You may add a section entitled ``Endorsements'', provided it contains
  249: nothing but endorsements of your Modified Version by various
  250: parties---for example, statements of peer review or that the text has
  251: been approved by an organization as the authoritative definition of a
  252: standard.
  253: 
  254: You may add a passage of up to five words as a Front-Cover Text, and a
  255: passage of up to 25 words as a Back-Cover Text, to the end of the list
  256: of Cover Texts in the Modified Version.  Only one passage of
  257: Front-Cover Text and one of Back-Cover Text may be added by (or
  258: through arrangements made by) any one entity.  If the Document already
  259: includes a cover text for the same cover, previously added by you or
  260: by arrangement made by the same entity you are acting on behalf of,
  261: you may not add another; but you may replace the old one, on explicit
  262: permission from the previous publisher that added the old one.
  263: 
  264: The author(s) and publisher(s) of the Document do not by this License
  265: give permission to use their names for publicity for or to assert or
  266: imply endorsement of any Modified Version.
  267: 
  268: @item
  269: COMBINING DOCUMENTS
  270: 
  271: You may combine the Document with other documents released under this
  272: License, under the terms defined in section 4 above for modified
  273: versions, provided that you include in the combination all of the
  274: Invariant Sections of all of the original documents, unmodified, and
  275: list them all as Invariant Sections of your combined work in its
  276: license notice.
  277: 
  278: The combined work need only contain one copy of this License, and
  279: multiple identical Invariant Sections may be replaced with a single
  280: copy.  If there are multiple Invariant Sections with the same name but
  281: different contents, make the title of each such section unique by
  282: adding at the end of it, in parentheses, the name of the original
  283: author or publisher of that section if known, or else a unique number.
  284: Make the same adjustment to the section titles in the list of
  285: Invariant Sections in the license notice of the combined work.
  286: 
  287: In the combination, you must combine any sections entitled ``History''
  288: in the various original documents, forming one section entitled
  289: ``History''; likewise combine any sections entitled ``Acknowledgments'',
  290: and any sections entitled ``Dedications''.  You must delete all sections
  291: entitled ``Endorsements.''
  292: 
  293: @item
  294: COLLECTIONS OF DOCUMENTS
  295: 
  296: You may make a collection consisting of the Document and other documents
  297: released under this License, and replace the individual copies of this
  298: License in the various documents with a single copy that is included in
  299: the collection, provided that you follow the rules of this License for
  300: verbatim copying of each of the documents in all other respects.
  301: 
  302: You may extract a single document from such a collection, and distribute
  303: it individually under this License, provided you insert a copy of this
  304: License into the extracted document, and follow this License in all
  305: other respects regarding verbatim copying of that document.
  306: 
  307: @item
  308: AGGREGATION WITH INDEPENDENT WORKS
  309: 
  310: A compilation of the Document or its derivatives with other separate
  311: and independent documents or works, in or on a volume of a storage or
  312: distribution medium, does not as a whole count as a Modified Version
  313: of the Document, provided no compilation copyright is claimed for the
  314: compilation.  Such a compilation is called an ``aggregate'', and this
  315: License does not apply to the other self-contained works thus compiled
  316: with the Document, on account of their being thus compiled, if they
  317: are not themselves derivative works of the Document.
  318: 
  319: If the Cover Text requirement of section 3 is applicable to these
  320: copies of the Document, then if the Document is less than one quarter
  321: of the entire aggregate, the Document's Cover Texts may be placed on
  322: covers that surround only the Document within the aggregate.
  323: Otherwise they must appear on covers around the whole aggregate.
  324: 
  325: @item
  326: TRANSLATION
  327: 
  328: Translation is considered a kind of modification, so you may
  329: distribute translations of the Document under the terms of section 4.
  330: Replacing Invariant Sections with translations requires special
  331: permission from their copyright holders, but you may include
  332: translations of some or all Invariant Sections in addition to the
  333: original versions of these Invariant Sections.  You may include a
  334: translation of this License provided that you also include the
  335: original English version of this License.  In case of a disagreement
  336: between the translation and the original English version of this
  337: License, the original English version will prevail.
  338: 
  339: @item
  340: TERMINATION
  341: 
  342: You may not copy, modify, sublicense, or distribute the Document except
  343: as expressly provided for under this License.  Any other attempt to
  344: copy, modify, sublicense or distribute the Document is void, and will
  345: automatically terminate your rights under this License.  However,
  346: parties who have received copies, or rights, from you under this
  347: License will not have their licenses terminated so long as such
  348: parties remain in full compliance.

  351: FUTURE REVISIONS OF THIS LICENSE
  352: 
  353: The Free Software Foundation may publish new, revised versions
  354: of the GNU Free Documentation License from time to time.  Such new
  355: versions will be similar in spirit to the present version, but may
  356: differ in detail to address new problems or concerns.  See
  357: @uref{http://www.gnu.org/copyleft/}.
  358: 
  359: Each version of the License is given a distinguishing version number.
  360: If the Document specifies that a particular numbered version of this
  361: License ``or any later version'' applies to it, you have the option of
  362: following the terms and conditions either of that specified version or
  363: of any later version that has been published (not as a draft) by the
  364: Free Software Foundation.  If the Document does not specify a version
  365: number of this License, you may choose any version ever published (not
  366: as a draft) by the Free Software Foundation.
