| <para> |
| The purpose of this License is to make a manual, textbook, or |
| other written document <quote>free</quote> in the sense of |
| freedom: to assure everyone the effective freedom to copy and |
| redistribute it, with or without modifying it, either |
| commercially or noncommercially. Secondarily, this License |
| preserves for the author and publisher a way to get credit for |
| their work, while not being considered responsible for |
| modifications made by others. |
| </para> |
| |
| <para> |
| This License is a kind of <quote>copyleft</quote>, which means |
| that derivative works of the document must themselves be free in |
| the same sense. It complements the GNU General Public License, |
| which is a copyleft license designed for free software. |
| </para> |
| |
| <para> |
| We have designed this License in order to use it for manuals for |
| free software, because free software needs free documentation: a |
| free program should come with manuals providing the same |
| freedoms that the software does. But this License is not limited |
| to software manuals; it can be used for any textual work, |
| regardless of subject matter or whether it is published as a |
| printed book. We recommend this License principally for works |
| whose purpose is instruction or reference. |

| <title>1. APPLICABILITY AND DEFINITIONS</title> |
| <para id="fdl-document"> |
| This License applies to any manual or other work that contains a |
| notice placed by the copyright holder saying it can be |
| distributed under the terms of this License. The |
| <quote>Document</quote>, below, refers to any such manual or |
| work. Any member of the public is a licensee, and is addressed |
| as <quote>you</quote>. |
| </para> |
| |
| <para id="fdl-modified"> |
| A <quote>Modified Version</quote> of the Document means any work |
| containing the Document or a portion of it, either copied |
| verbatim, or with modifications and/or translated into another |
| language. |
| </para> |
| |
| <para id="fdl-secondary"> |
| A <quote>Secondary Section</quote> is a named appendix or a |
| front-matter section of the <link |
| linkend="fdl-document">Document</link> that deals exclusively |
| with the relationship of the publishers or authors of the |
| Document to the Document's overall subject (or to related |
| matters) and contains nothing that could fall directly within |
| that overall subject. (For example, if the Document is in part a |
| textbook of mathematics, a Secondary Section may not explain any |
| mathematics.) The relationship could be a matter of historical |
| connection with the subject or with related matters, or of |
| legal, commercial, philosophical, ethical or political position |
| regarding them. |
| </para> |
| |
| <para id="fdl-invariant"> |
| The <quote>Invariant Sections</quote> are certain <link |
| linkend="fdl-secondary"> Secondary Sections</link> whose titles |
| are designated, as being those of Invariant Sections, in the |
| notice that says that the <link |
| linkend="fdl-document">Document</link> is released under this |
| License. |
| </para> |
| |
| <para id="fdl-cover-texts"> |
| The <quote>Cover Texts</quote> are certain short passages of |
| text that are listed, as Front-Cover Texts or Back-Cover Texts, |
| in the notice that says that the <link |
| linkend="fdl-document">Document</link> is released under this |
| License. |
| </para> |
| |
| <para id="fdl-transparent"> |
| A <quote>Transparent</quote> copy of the <link |
| linkend="fdl-document"> Document</link> means a machine-readable |
| copy, represented in a format whose specification is available |
| to the general public, whose contents can be viewed and edited |
| directly and straightforwardly with generic text editors or (for |
| images composed of pixels) generic paint programs or (for |
| drawings) some widely available drawing editor, and that is |
| suitable for input to text formatters or for automatic |
| translation to a variety of formats suitable for input to text |
| formatters. A copy made in an otherwise Transparent file format |
| whose markup has been designed to thwart or discourage |
| subsequent modification by readers is not Transparent. A copy |
| that is not <quote>Transparent</quote> is called |
| <quote>Opaque</quote>. |
| </para> |
| |
| <para> |
| Examples of suitable formats for Transparent copies include |
| plain ASCII without markup, Texinfo input format, LaTeX input |
| format, SGML or XML using a publicly available DTD, and |
| standard-conforming simple HTML designed for human |
| modification. Opaque formats include PostScript, PDF, |
| proprietary formats that can be read and edited only by |
| proprietary word processors, SGML or XML for which the DTD |
| and/or processing tools are not generally available, and the |
| machine-generated HTML produced by some word processors for |
| output purposes only. |
| </para> |

| <para id="fdl-title-page"> |
| The <quote>Title Page</quote> means, for a printed book, the |
| title page itself, plus such following pages as are needed to |
| hold, legibly, the material this License requires to appear in |
| the title page. For works in formats which do not have any title |
| page as such, <quote>Title Page</quote> means the text near the |
| most prominent appearance of the work's title, preceding the |
| beginning of the body of the text. |

| <title>2. VERBATIM COPYING</title> |
| <para> |
| You may copy and distribute the <link |
| linkend="fdl-document">Document</link> in any medium, either |
| commercially or noncommercially, provided that this License, the |
| copyright notices, and the license notice saying this License |
| applies to the Document are reproduced in all copies, and that |
| you add no other conditions whatsoever to those of this |
| License. You may not use technical measures to obstruct or |
| control the reading or further copying of the copies you make or |
| distribute. However, you may accept compensation in exchange for |
| copies. If you distribute a large enough number of copies you |
| must also follow the conditions in <link |
| linkend="fdl-section3">section 3</link>. |
| </para> |

| <para> |
| You may also lend copies, under the same conditions stated |
| above, and you may publicly display copies. |

| <sect1 id="fdl-section3"> |
| <title>3. COPYING IN QUANTITY</title> |
| <para> |
| If you publish printed copies of the <link |
| linkend="fdl-document">Document</link> numbering more than 100, |
| and the Document's license notice requires <link |
| linkend="fdl-cover-texts">Cover Texts</link>, you must enclose |
| the copies in covers that carry, clearly and legibly, all these |
| Cover Texts: Front-Cover Texts on the front cover, and |
| Back-Cover Texts on the back cover. Both covers must also |
| clearly and legibly identify you as the publisher of these |
| copies. The front cover must present the full title with all |
| words of the title equally prominent and visible. You may add |
| other material on the covers in addition. Copying with changes |
| limited to the covers, as long as they preserve the title of the |
| <link linkend="fdl-document">Document</link> and satisfy these |
| conditions, can be treated as verbatim copying in other |
| respects. |
| </para> |
| |
| <para> |
| If the required texts for either cover are too voluminous to fit |
| legibly, you should put the first ones listed (as many as fit |
| reasonably) on the actual cover, and continue the rest onto |
| adjacent pages. |
| </para> |
| |
| <para> |
| If you publish or distribute <link |
| linkend="fdl-transparent">Opaque</link> copies of the <link |
| linkend="fdl-document">Document</link> numbering more than 100, |
| you must either include a machine-readable <link |
| linkend="fdl-transparent">Transparent</link> copy along with |
| each Opaque copy, or state in or with each Opaque copy a |
| publicly-accessible computer-network location containing a |
| complete Transparent copy of the Document, free of added |
| material, which the general network-using public has access to |
| download anonymously at no charge using public-standard network |
| protocols. If you use the latter option, you must take |
| reasonably prudent steps, when you begin distribution of Opaque |
| copies in quantity, to ensure that this Transparent copy will |
| remain thus accessible at the stated location until at least one |
| year after the last time you distribute an Opaque copy (directly |
| or through your agents or retailers) of that edition to the |
| public. |
