| 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, | |

| 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 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. | |
| </para> | |

| <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. | |

| It is requested, but not required, that you contact the authors | |
| of the <link linkend="fdl-document">Document</link> well before | |
