-<section id="gfdl-0"><title>PREAMBLE</title>
-
-<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>
-</section>
-
-<section id="gfdl-1"><title>APPLICABILITY AND DEFINITIONS</title>
-
-<para id="gfdl-doc">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 id="gfdl-mod-ver">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 id="gfdl-secnd-sect">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 id="gfdl-inv-sect">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 id="gfdl-cov-text">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 id="gfdl-transparent">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 id="gfdl-title-page">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 id="gfdl-entitled">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>
-</section>
-
-<section id="gfdl-2"><title>VERBATIM COPYING</title>
-
-<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>
-</section>
-
-<section id="gfdl-3"><title>COPYING IN QUANTITY</title>
-
-<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>
-</section>
-
-<section id="gfdl-4"><title>MODIFICATIONS</title>
-
-<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. In addition, you must do these things in the
-Modified Version:</para>
-
-<orderedlist id="gfdl-modif-cond" numeration="upperalpha">
-<listitem><simpara>Use in the Title Page (and on the covers, if any) a
- title distinct from that of the Document, and from those of previous
- versions (which should, if there were any, be listed in the History
- section of the Document). You may use the same title as a previous
- version if the original publisher of that version gives permission.
-</simpara></listitem>
-<listitem><simpara>List on the Title Page, as authors, one or more
- persons or entities responsible for authorship of the modifications in
- the Modified Version, together with at least five of the principal
- authors of the Document (all of its principal authors, if it has fewer
- than five), unless they release you from this requirement.
-</simpara></listitem>
-<listitem><simpara>State on the Title page the name of the publisher of
- the Modified Version, as the publisher.</simpara></listitem>
-<listitem><simpara>Preserve all the copyright notices of the Document.
-</simpara></listitem>
-<listitem><simpara>Add an appropriate copyright notice for your
- modifications adjacent to the other copyright notices.
-</simpara></listitem>
-<listitem><simpara>Include, immediately after the copyright notices, a
- license notice giving the public permission to use the Modified
- Version under the terms of this License, in the form shown in the
- <link linkend="gfdl-addendum">Addendum</link> below.
-</simpara></listitem>
-<listitem><simpara>Preserve in that license notice the full lists of
- Invariant Sections and required Cover Texts given in the Document's
- license notice.</simpara></listitem>
-<listitem><simpara>Include an unaltered copy of this License.
-</simpara></listitem>
-<listitem><simpara>Preserve the section Entitled "History", Preserve its
- Title, and add to it an item stating at least the title, year, new
- authors, and publisher of the Modified Version as given on the Title
- Page. If there is no section Entitled "History" in the Document,
- create one stating the title, year, authors, and publisher of the
- Document as given on its Title Page, then add an item describing the
- Modified Version as stated in the previous sentence.
-</simpara></listitem>
-<listitem><simpara>Preserve the network location, if any, given in the
- Document for public access to a Transparent copy of the Document, and
- likewise the network locations given in the Document for previous
- versions it was based on. These may be placed in the "History"
- section. You may omit a network location for a work that was
- published at least four years before the Document itself, or if the
- original publisher of the version it refers to gives permission.
-</simpara></listitem>
-<listitem><simpara>For any section Entitled "Acknowledgements" or
- "Dedications", Preserve the Title of the section, and preserve in the
- section all the substance and tone of each of the contributor
- acknowledgements and/or dedications given therein.
-</simpara></listitem>
-<listitem><simpara>Preserve all the Invariant Sections of the Document,
- unaltered in their text and in their titles. Section numbers or the
- equivalent are not considered part of the section titles.
-</simpara></listitem>
-<listitem><simpara>Delete any section Entitled "Endorsements".
- Such a section may not be included in the Modified Version.
-</simpara></listitem>
-<listitem><simpara>Do not retitle any existing section to be Entitled
- "Endorsements" or to conflict in title with any Invariant Section.
-</simpara></listitem>
-<listitem><simpara>Preserve any Warranty Disclaimers.
-</simpara></listitem>
-</orderedlist>
-
-<para>If the Modified Version includes new front-matter sections or
-appendices that qualify as Secondary Sections and contain no material
-copied from the Document, you may at your option designate some or all
-of these sections as invariant. To do this, add their titles to the
-list of Invariant Sections in the Modified Version's license notice.
-These titles must be distinct from any other section titles.</para>
-
-<para>You may add a section Entitled "Endorsements", provided it
-contains nothing but endorsements of your Modified Version by various
-parties--for example, statements of peer review or that the text has
-been approved by an organization as the authoritative definition of a
-standard.</para>
-
-<para>You may add a passage of up to five words as a Front-Cover Text,
-and a passage of up to 25 words as a Back-Cover Text, to the end of the
-list of Cover Texts in the Modified Version. Only one passage of
-Front-Cover Text and one of Back-Cover Text may be added by (or through
-arrangements made by) any one entity. If the Document already includes
-a cover text for the same cover, previously added by you or by
-arrangement made by the same entity you are acting on behalf of, you may
-not add another; but you may replace the old one, on explicit permission
-from the previous publisher that added the old one.</para>
-
-<para>The author(s) and publisher(s) of the Document do not by this
-License give permission to use their names for publicity for or to
-assert or imply endorsement of any Modified Version.</para>
-</section>
-
-<section id="gfdl-5"><title>COMBINING DOCUMENTS</title>
-
-<para>You may combine the Document with other documents released under
-this License, under the terms defined in <link linkend="gfdl-4">section
-4</link> above for modified versions, provided that you include in the
-combination all of the Invariant Sections of all of the original
-documents, unmodified, and list them all as Invariant Sections of your
-combined work in its license notice, and that you preserve all their
-Warranty Disclaimers.</para>
-
-<para>The combined work need only contain one copy of this License, and
-multiple identical Invariant Sections may be replaced with a single
-copy. If there are multiple Invariant Sections with the same name but
-different contents, 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>
-
-<para>In the combination, you must combine any sections Entitled
-"History" in the various original documents, forming one section
-Entitled "History"; likewise combine any sections Entitled
-"Acknowledgements", and any sections Entitled "Dedications". You must
-delete all sections Entitled "Endorsements".</para>
-</section>
-
-<section id="gfdl-6"><title>COLLECTIONS OF DOCUMENTS</title>
-
-<para>You may make a collection consisting of the Document and other
-documents released under this License, and replace the individual copies
-of this License in the various documents with a single copy that is
-included 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.</para>
-</section>
-
-<section id="gfdl-7"><title>AGGREGATION WITH INDEPENDENT WORKS</title>
-
-<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 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.</para>
-</section>
-
-<section id="gfdl-8"><title>TRANSLATION</title>
-
-<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 Warrany 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.</para>
-</section>
-
-<section id="gfdl-9"><title>TERMINATION</title>
-
-<para>You may not copy, modify, sublicense, or distribute the Document
-except as 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 who have received copies, or rights, from you under this License
-will not have their licenses terminated so long as such parties remain
-in full compliance.</para>
-</section>
-
-<section id="gfdl-10"><title>FUTURE REVISIONS OF THIS LICENSE</title>
-
-<para>The Free Software Foundation may publish new, revised versions of
-the GNU Free Documentation License from time to time. Such new versions
-will be similar in spirit to the present version, but may differ in
-detail to address new problems or concerns. See
-http://www.gnu.org/copyleft/.</para>
-
-<para>Each version of the License is given a distinguishing version
-number. If the Document specifies that a particular numbered version of
-this License "or any later version" applies to it, you have the option
-of following the terms and conditions either of that specified version
-or of any later version that has been published (not as a draft) by the
-Free Software Foundation. If the Document does not specify a version
-number of this License, you may choose any version ever published (not
-as a draft) by the Free Software Foundation.</para>
-</section>
-
-<section id="gfdl-addendum"><title>ADDENDUM: How to use this License for
- your documents</title>
-
-<para>To use this License in a document you have written, include a copy
-of the License in the document and put the following copyright and
-license notices just after the title page:</para>
-
-<blockquote id="copyright-sample"><para>
- Copyright (c) YEAR YOUR NAME.
- Permission is granted to copy, distribute and/or modify this document
- under the terms of the GNU Free Documentation License, Version 1.2
- or any later version published by the Free Software Foundation;
- with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
- A copy of the license is included in the section entitled "GNU
- Free Documentation License".
-</para></blockquote>
-
-<para>If you have Invariant Sections, Front-Cover Texts and Back-Cover
-Texts, replace the "with...Texts." line with this:</para>
-
-<blockquote id="inv-cover-sample"><para>
- with the Invariant Sections being LIST THEIR TITLES, with the
- Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
-</para></blockquote>
-
-<para>If you have Invariant Sections without Cover Texts, or some other
-combination of the three, merge those two alternatives to suit the
-situation.</para>
-
-<para>If your document contains nontrivial examples of program code, we
-recommend releasing these examples in parallel under your choice of free
-software license, such as the GNU General Public License, to permit
-their use in free software.</para>
