  33       The purpose of this License is to make a manual, textbook, or
  34       other written document <quote>free</quote> in the sense of
  35       freedom: to assure everyone the effective freedom to copy and
  36       redistribute it, with or without modifying it, either
  37       commercially or noncommercially. Secondarily, this License
  38       preserves for the author and publisher a way to get credit for
  39       their work, while not being considered responsible for
  40       modifications made by others.

  43     <para>
  44       This License is a kind of <quote>copyleft</quote>, which means
  45       that derivative works of the document must themselves be free in
  46       the same sense. It complements the GNU General Public License,
  47       which is a copyleft license designed for free software.

  50     <para>
  51       We have designed this License in order to use it for manuals for
  52       free software, because free software needs free documentation: a
  53       free program should come with manuals providing the same
  54       freedoms that the software does. But this License is not limited
  55       to software manuals; it can be used for any textual work,
  56       regardless of subject matter or whether it is published as a
  57       printed book. We recommend this License principally for works
  58       whose purpose is instruction or reference.

  64       This License applies to any manual or other work that contains a
  65       notice placed by the copyright holder saying it can be
  66       distributed under the terms of this License. The
  67       <quote>Document</quote>, below, refers to any such manual or
  68       work. Any member of the public is a licensee, and is addressed
  69       as <quote>you</quote>.

  73       A <quote>Modified Version</quote> of the Document means any work

  83       with the relationship of the publishers or authors of the
  84       Document to the Document's overall subject (or to related
  85       matters) and contains nothing that could fall directly within
  86       that overall subject. (For example, if the Document is in part a
  87       textbook of mathematics, a Secondary Section may not explain any
  88       mathematics.)  The relationship could be a matter of historical
  89       connection with the subject or with related matters, or of
  90       legal, commercial, philosophical, ethical or political position
  91       regarding them.

 112       A <quote>Transparent</quote> copy of the <link

 114       copy, represented in a format whose specification is available
 115       to the general public, whose contents can be viewed and edited
 116       directly and straightforwardly with generic text editors or (for
 117       images composed of pixels) generic paint programs or (for
 118       drawings) some widely available drawing editor, and that is
 119       suitable for input to text formatters or for automatic
 120       translation to a variety of formats suitable for input to text
 121       formatters. A copy made in an otherwise Transparent file format
 122       whose markup has been designed to thwart or discourage
 123       subsequent modification by readers is not Transparent.  A copy
 124       that is not <quote>Transparent</quote> is called
 125       <quote>Opaque</quote>.

 129       Examples of suitable formats for Transparent copies include
 130       plain ASCII without markup, Texinfo input format, LaTeX input
 131       format, SGML or XML using a publicly available DTD, and
 132       standard-conforming simple HTML designed for human
 133       modification. Opaque formats include PostScript, PDF,
 134       proprietary formats that can be read and edited only by
 135       proprietary word processors, SGML or XML for which the DTD
 136       and/or processing tools are not generally available, and the
 137       machine-generated HTML produced by some word processors for
 138       output purposes only.

 144       hold, legibly, the material this License requires to appear in
 145       the title page. For works in formats which do not have any title
 146       page as such, <quote>Title Page</quote> means the text near the
 147       most prominent appearance of the work's title, preceding the

 155       You may copy and distribute the <link
 156       linkend="fdl-document">Document</link> in any medium, either
 157       commercially or noncommercially, provided that this License, the
 158       copyright notices, and the license notice saying this License
 159       applies to the Document are reproduced in all copies, and that
 160       you add no other conditions whatsoever to those of this
 161       License. You may not use technical measures to obstruct or
 162       control the reading or further copying of the copies you make or
 163       distribute. However, you may accept compensation in exchange for
 164       copies. If you distribute a large enough number of copies you
 165       must also follow the conditions in <link
 166       linkend="fdl-section3">section 3</link>.
 167     </para>
 168
 169     <para>

 178       If you publish printed copies of the <link
 179       linkend="fdl-document">Document</link> numbering more than 100,
 180       and the Document's license notice requires <link
 181       linkend="fdl-cover-texts">Cover Texts</link>, you must enclose
 182       the copies in covers that carry, clearly and legibly, all these
 183       Cover Texts: Front-Cover Texts on the front cover, and
 184       Back-Cover Texts on the back cover. Both covers must also
 185       clearly and legibly identify you as the publisher of these
 186       copies. The front cover must present the full title with all
 187       words of the title equally prominent and visible. You may add
 188       other material on the covers in addition. Copying with changes
 189       limited to the covers, as long as they preserve the title of the
 190       <link linkend="fdl-document">Document</link> and satisfy these
 191       conditions, can be treated as verbatim copying in other
 192       respects.

 194
 195     <para>
 196       If the required texts for either cover are too voluminous to fit
 197       legibly, you should put the first ones listed (as many as fit
 198       reasonably) on the actual cover, and continue the rest onto
 199       adjacent pages.

 203       If you publish or distribute <link
 204       linkend="fdl-transparent">Opaque</link> copies of the <link
 205       linkend="fdl-document">Document</link> numbering more than 100,
 206       you must either include a machine-readable <link
 207       linkend="fdl-transparent">Transparent</link> copy along with
 208       each Opaque copy, or state in or with each Opaque copy a
 209       publicly-accessible computer-network location containing a
 210       complete Transparent copy of the Document, free of added
 211       material, which the general network-using public has access to
 212       download anonymously at no charge using public-standard network
 213       protocols. If you use the latter option, you must take
 214       reasonably prudent steps, when you begin distribution of Opaque
 215       copies in quantity, to ensure that this Transparent copy will
 216       remain thus accessible at the stated location until at least one
 217       year after the last time you distribute an Opaque copy (directly
 218       or through your agents or retailers) of that edition to the
 219       public.
