| </bridgehead> |
| <para> |
| The purpose of this License is to make a manual, textbook, or other |
| functional and useful document "free" 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 "copyleft", 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.</para> |
| <bridgehead id="fdl-1-definitions" renderas="sect1"> |
| 1. APPLICABILITY AND DEFINITIONS |
| </bridgehead> |
| <para> |
| This License applies to any manual or other work, in any medium, that |
| contains a notice placed by the copyright holder saying it can be |
| distributed under the terms of this License. Such a notice grants a |
| world-wide, royalty-free license, unlimited in duration, to use that work |
| under the conditions stated herein. The "Document", below, refers to any |
| such manual or work. Any member of the public is a licensee, and is |
| addressed as "you". You accept the license if you copy, modify or |
| distribute the work in a way requiring permission under copyright |
| law. |
| </para> |
| <para> |
| A "Modified Version" 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> |
| A "Secondary Section" is a named appendix or a front-matter section of the |
| Document 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. (Thus, 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> |
| The "Invariant Sections" are certain Secondary Sections whose titles are |
| designated, as being those of Invariant Sections, in the notice that says |
| that the Document is released under this License. If a section does not |
| fit the above definition of Secondary then it is not allowed to be |
| designated as Invariant. The Document may contain zero Invariant |
| Sections. If the Document does not identify any Invariant Sections then |
| there are none. |
| </para> |
| <para> |
| The "Cover Texts" are certain short passages of text that are listed, as |
| Front-Cover Texts or Back-Cover Texts, in the notice that says that the |
| Document is released under this License. A Front-Cover Text may be at |
| most 5 words, and a Back-Cover Text may be at most 25 words. |
| </para> |
| <para> |
| A "Transparent" copy of the Document means a machine-readable copy, |
| represented in a format whose specification is available to the general |
| public, that is suitable for revising the document 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, or absence of markup, |
| has been arranged to thwart or discourage subsequent modification by |
| readers is not Transparent. An image format is not Transparent if used |
| for any substantial amount of text. A copy that is not "Transparent" is |
| called "Opaque". |
| </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, |
| PostScript or PDF designed for human modification. Examples of |
| transparent image formats include PNG, XCF and JPG. Opaque formats |
| include 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, PostScript or PDF produced by some word processors for output |
| purposes only. |
| </para> |
| <para> |
| The "Title Page" 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, "Title Page" means the text near the |
| most prominent appearance of the work's title, preceding the beginning of |
| the body of the text. |
| </para> |
| <para> |
| A section "Entitled XYZ" means a named subunit of the Document whose title |
| either is precisely XYZ or contains XYZ in parentheses following text that |
| translates XYZ in another language. (Here XYZ stands for a specific |
| section name mentioned below, such as "Acknowledgements", "Dedications", |
| "Endorsements", or "History".) To "Preserve the Title" of such a section |
| when you modify the Document means that it remains a section "Entitled |
| XYZ" according to this definition. |
| </para> |
| <para> |
| The Document may include Warranty Disclaimers next to the notice which |
| states that this License applies to the Document. These Warranty |
| Disclaimers are considered to be included by reference in this License, |
| but only as regards disclaiming warranties: any other implication that |
| these Warranty Disclaimers may have is void and has no effect on the |
| meaning of this License. |
| </para> |
| <bridgehead id="VerbatimCopying" renderas="sect1"> |
| 2. VERBATIM COPYING |
| </bridgehead> |
| <para> |
| You may copy and distribute the Document 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 section 3. |
| </para> |
| <para> |
| You may also lend copies, under the same conditions stated above, and you |
| may publicly display copies. |
| </para> |
| <bridgehead id="QuantityCopying" renderas="sect1"> |
| 3. COPYING IN QUANTITY |
| </bridgehead> |
| <para> |
| If you publish printed copies (or copies in media that commonly have |
| printed covers) of the Document, numbering more than 100, and the |
| Document's license notice requires Cover Texts, 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 Document 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 Opaque copies of the Document numbering more |
| than 100, you must either include a machine-readable Transparent copy |
| along with each Opaque copy, or state in or with each Opaque copy a |
| computer-network location from which the general network-using public has |
| access to download using public-standard network protocols a complete |
| Transparent copy of the Document, free of added material. 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. |
| </para> |
| <para> |
| It is requested, but not required, that you contact the authors of the |
| Document well before redistributing any large number of copies, to give |
| them a chance to provide you with an updated version of the |
| Document. |
| </para> |
| <bridgehead id="Modifications" renderas="sect1"> |
| 4. MODIFICATIONS |

| <para> |
| You may copy and distribute a Modified Version of the Document under the |
| conditions of sections 2 and 3 above, provided that you release the |
| Modified Version under precisely this License, with the Modified Version |
| filling the role of the Document, thus licensing distribution and |
| modification of the Modified Version to whoever possesses a copy of it. |

| You may add a passage of up to five words as a Front-Cover Text, and a |

| 5. COMBINING DOCUMENTS |
| </bridgehead> |
| <para> |
| You may combine the Document with other documents released under this |

| make the title of each such section unique by adding at the end of it, in |
| parentheses, the name of the original author or publisher of that section |
| if known, or else a unique number. Make the same adjustment to the |
| section titles in the list of Invariant Sections in the license notice of |
| the combined work. |

| <para> |
| In the combination, you must combine any sections Entitled "History" in |

| the collection, provided that you follow the rules of this License for |
| verbatim copying of each of the documents in all other respects. |
| </para> |
| <para> |
| You may extract a single document from such a collection, and distribute |
| it individually under this License, provided you insert a copy of this |
| License into the extracted document, and follow this License in all other |
| respects regarding verbatim copying of that document. |

| <bridgehead id="Aggregation" renderas="sect1"> |
| 7. AGGREGATION WITH INDEPENDENT WORKS |
| </bridgehead> |
| <para> |
| A compilation of the Document or its derivatives with other separate and |
| independent documents or works, in or on a volume of a storage or |
| distribution medium, is called an "aggregate" if the copyright resulting |
| from the compilation is not used to limit the legal rights of the |
| compilation's users beyond what the individual works permit. When the |
| Document is included in an aggregate, this License does not apply to the |
| other works in the aggregate which are not themselves derivative works of |
| the Document. |
| </para> |
| <para> |
| If the Cover Text requirement of section 3 is applicable to these copies |
| of the Document, then if the Document is less than one half of the entire |
| aggregate, the Document's Cover Texts may be placed on covers that bracket |
| the Document within the aggregate, or the electronic equivalent of covers |
| if the Document is in electronic form. Otherwise they must appear on |
| printed covers that bracket the whole aggregate. |

| 8. TRANSLATION |
| </bridgehead> |
| <para> |
| Translation is considered a kind of modification, so you may distribute |
| translations of the Document under the terms of section 4. Replacing |
| Invariant Sections with translations requires special permission from |
| their copyright holders, but you may include translations of some or all |
| Invariant Sections in addition to the original versions of these Invariant |
| Sections. You may include a translation of this License, and all the |
| license notices in the Document, and any Warranty Disclaimers, provided |
| that you also include the original English version of this License and the |
| original versions of those notices and disclaimers. In case of a |
| disagreement between the translation and the original version of this |
| License or a notice or disclaimer, the original version will prevail. |
| </para> |
| <para> |
| If a section in the Document is Entitled "Acknowledgements", |
| "Dedications", or "History", the requirement (section 4) to Preserve its |
| Title (section 1) will typically require changing the actual title. |

| expressly provided for under this License. Any other attempt to copy, |
| modify, sublicense or distribute the Document is void, and will |
| automatically terminate your rights under this License. However, parties |
