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

79 <para id="fdl-secondary">
80 A <quote>Secondary Section</quote> is a named appendix or a
81 front-matter section of the <link

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

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

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

177 <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.
193 </para>
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.

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.
