PREAMBLE</title> 32 <para> 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. 41 </para> 42 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. 48 </para> 49 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. 59 </para> 60 </sect1> 61 <sect1 id="fdl-section1"> 62 <title>1. APPLICABILITY AND DEFINITIONS</title> 63 <para id="fdl-document"> 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>. 70 </para> 71 72 <para id="fdl-modified"> 73 A <quote>Modified Version</quote> of the Document means any work 74 containing the Document or a portion of it, either copied 75 verbatim, or with modifications and/or translated into another 76 language. 77 </para> 78 79 <para id="fdl-secondary"> 80 A <quote>Secondary Section</quote> is a named appendix or a 81 front-matter section of the <link 82 linkend="fdl-document">Document</link> that deals exclusively 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. 92 </para> 93 94 <para id="fdl-invariant"> 95 The <quote>Invariant Sections</quote> are certain <link 96 linkend="fdl-secondary"> Secondary Sections</link> whose titles 97 are designated, as being those of Invariant Sections, in the 98 notice that says that the <link 99 linkend="fdl-document">Document</link> is released under this 100 License. 101 </para> 102 103 <para id="fdl-cover-texts"> 104 The <quote>Cover Texts</quote> are certain short passages of 105 text that are listed, as Front-Cover Texts or Back-Cover Texts, 106 in the notice that says that the <link 107 linkend="fdl-document">Document</link> is released under this 108 License. 109 </para> 110 111 <para id="fdl-transparent"> 112 A <quote>Transparent</quote> copy of the <link 113 linkend="fdl-document"> Document</link> means a machine-readable 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>. 126 </para> 127 128 <para> 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. 139 </para> 140 141 <para id="fdl-title-page"> 142 The <quote>Title Page</quote> means, for a printed book, the 143 title page itself, plus such following pages as are needed to 144 hold, legibly, the material this License requires to appear in 145 the title page.

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. 200 </para> 201 202 <para> 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.
