-<pre class="display">Copyright &copy; 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
-<a href="http://fsf.org/">http://fsf.org/</a>
-
-Everyone is permitted to copy and distribute verbatim copies
-of this license document, but changing it is not allowed.
-</pre></div>
-
-<ol start="0">
-<li> PREAMBLE
-
-<p>The purpose of this License is to make a manual, textbook, or other
-functional and useful document <em>free</em> 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.
-</p>
-<p>This License is a kind of &ldquo;copyleft&rdquo;, 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.
-</p>
-<p>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.
-</p>
-</li><li> APPLICABILITY AND DEFINITIONS
-
-<p>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 &ldquo;Document&rdquo;, below,
-refers to any such manual or work. Any member of the public is a
-licensee, and is addressed as &ldquo;you&rdquo;. You accept the license if you
-copy, modify or distribute the work in a way requiring permission
-under copyright law.
-</p>
-<p>A &ldquo;Modified Version&rdquo; 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.
-</p>
-<p>A &ldquo;Secondary Section&rdquo; 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&rsquo;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.
-</p>
-<p>The &ldquo;Invariant Sections&rdquo; 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.
-</p>
-<p>The &ldquo;Cover Texts&rdquo; 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.
-</p>
-<p>A &ldquo;Transparent&rdquo; 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 &ldquo;Transparent&rdquo; is called &ldquo;Opaque&rdquo;.
-</p>
-<p>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.
-</p>
-<p>The &ldquo;Title Page&rdquo; 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, &ldquo;Title Page&rdquo; means
-the text near the most prominent appearance of the work&rsquo;s title,
-preceding the beginning of the body of the text.
-</p>
-<p>The &ldquo;publisher&rdquo; means any person or entity that distributes copies
-of the Document to the public.
-</p>
-<p>A section &ldquo;Entitled XYZ&rdquo; 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 &ldquo;Acknowledgements&rdquo;,
-&ldquo;Dedications&rdquo;, &ldquo;Endorsements&rdquo;, or &ldquo;History&rdquo;.) To &ldquo;Preserve the Title&rdquo;
-of such a section when you modify the Document means that it remains a
-section &ldquo;Entitled XYZ&rdquo; according to this definition.
-</p>
-<p>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.
-</p>
-</li><li> VERBATIM COPYING
-
-<p>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.
-</p>
-<p>You may also lend copies, under the same conditions stated above, and
-you may publicly display copies.
-</p>
-</li><li> COPYING IN QUANTITY
-
-<p>If you publish printed copies (or copies in media that commonly have
-printed covers) of the Document, numbering more than 100, and the
-Document&rsquo;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.
-</p>
-<p>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.
-</p>
-<p>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.
-</p>
-<p>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.
-</p>
-</li><li> MODIFICATIONS
-
-<p>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:
-</p>
-<ol type="A" start="1">
-<li> 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.
-
-</li><li> 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.
-
-</li><li> State on the Title page the name of the publisher of the
-Modified Version, as the publisher.
-
-</li><li> Preserve all the copyright notices of the Document.
-
-</li><li> Add an appropriate copyright notice for your modifications
-adjacent to the other copyright notices.
-
-</li><li> 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 Addendum below.
-
-</li><li> Preserve in that license notice the full lists of Invariant Sections
-and required Cover Texts given in the Document&rsquo;s license notice.
-
-</li><li> Include an unaltered copy of this License.
-
-</li><li> Preserve the section Entitled &ldquo;History&rdquo;, 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 &ldquo;History&rdquo; 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.
-
-</li><li> 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 &ldquo;History&rdquo; 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.
-
-</li><li> For any section Entitled &ldquo;Acknowledgements&rdquo; or &ldquo;Dedications&rdquo;, 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.
-
-</li><li> 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.
-
-</li><li> Delete any section Entitled &ldquo;Endorsements&rdquo;. Such a section
-may not be included in the Modified Version.
-
-</li><li> Do not retitle any existing section to be Entitled &ldquo;Endorsements&rdquo; or
-to conflict in title with any Invariant Section.
-
-</li><li> Preserve any Warranty Disclaimers.
-</li></ol>
-
-<p>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&rsquo;s license notice.
-These titles must be distinct from any other section titles.
-</p>
-<p>You may add a section Entitled &ldquo;Endorsements&rdquo;, provided it contains
-nothing but endorsements of your Modified Version by various
-parties&mdash;for example, statements of peer review or that the text has
-been approved by an organization as the authoritative definition of a
-standard.
-</p>
-<p>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.
-</p>
-<p>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.
-</p>
-</li><li> COMBINING DOCUMENTS
-
-<p>You may combine the Document with other documents released under this
-License, under the terms defined in section 4 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.
-</p>
-<p>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.
-</p>
-<p>In the combination, you must combine any sections Entitled &ldquo;History&rdquo;
-in the various original documents, forming one section Entitled
-&ldquo;History&rdquo;; likewise combine any sections Entitled &ldquo;Acknowledgements&rdquo;,
-and any sections Entitled &ldquo;Dedications&rdquo;. You must delete all
-sections Entitled &ldquo;Endorsements.&rdquo;
-</p>
-</li><li> COLLECTIONS OF DOCUMENTS
-
-<p>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.
-</p>
-<p>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.
-</p>
-</li><li> AGGREGATION WITH INDEPENDENT WORKS
-
-<p>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 &ldquo;aggregate&rdquo; if the copyright
-resulting from the compilation is not used to limit the legal rights
-of the compilation&rsquo;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.
-</p>
-<p>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&rsquo;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.
-</p>
-</li><li> TRANSLATION
-
-<p>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.
-</p>
-<p>If a section in the Document is Entitled &ldquo;Acknowledgements&rdquo;,
-&ldquo;Dedications&rdquo;, or &ldquo;History&rdquo;, the requirement (section 4) to Preserve
-its Title (section 1) will typically require changing the actual
-title.
-</p>
-</li><li> TERMINATION
-
-<p>You may not copy, modify, sublicense, or distribute the Document
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense, or distribute it is void, and
-will automatically terminate your rights under this License.
-</p>
-<p>However, if you cease all violation of this License, then your license
-from a particular copyright holder is reinstated (a) provisionally,
-unless and until the copyright holder explicitly and finally
-terminates your license, and (b) permanently, if the copyright holder
-fails to notify you of the violation by some reasonable means prior to
-60 days after the cessation.
-</p>
-<p>Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-</p>
-<p>Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License. If your rights have been terminated and not permanently
-reinstated, receipt of a copy of some or all of the same material does
-not give you any rights to use it.
-</p>
-</li><li> FUTURE REVISIONS OF THIS LICENSE
-
-<p>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
-<a href="http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</a>.
-</p>
-<p>Each version of the License is given a distinguishing version number.
-If the Document specifies that a particular numbered version of this
-License &ldquo;or any later version&rdquo; 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. If the Document
-specifies that a proxy can decide which future versions of this
-License can be used, that proxy&rsquo;s public statement of acceptance of a
-version permanently authorizes you to choose that version for the
-Document.
-</p>
-</li><li> RELICENSING
-
-<p>&ldquo;Massive Multiauthor Collaboration Site&rdquo; (or &ldquo;MMC Site&rdquo;) means any
-World Wide Web server that publishes copyrightable works and also
-provides prominent facilities for anybody to edit those works. A
-public wiki that anybody can edit is an example of such a server. A
-&ldquo;Massive Multiauthor Collaboration&rdquo; (or &ldquo;MMC&rdquo;) contained in the
-site means any set of copyrightable works thus published on the MMC
-site.
-</p>
-<p>&ldquo;CC-BY-SA&rdquo; means the Creative Commons Attribution-Share Alike 3.0
-license published by Creative Commons Corporation, a not-for-profit
-corporation with a principal place of business in San Francisco,
-California, as well as future copyleft versions of that license
-published by that same organization.
-</p>
-<p>&ldquo;Incorporate&rdquo; means to publish or republish a Document, in whole or
-in part, as part of another Document.
-</p>
-<p>An MMC is &ldquo;eligible for relicensing&rdquo; if it is licensed under this
-License, and if all works that were first published under this License
-somewhere other than this MMC, and subsequently incorporated in whole
-or in part into the MMC, (1) had no cover texts or invariant sections,
-and (2) were thus incorporated prior to November 1, 2008.
-</p>
-<p>The operator of an MMC Site may republish an MMC contained in the site
-under CC-BY-SA on the same site at any time before August 1, 2009,
-provided the MMC is eligible for relicensing.

-<span id="ADDENDUM_003a-How-to-use-this-License-for-your-documents"></span><h3 class="heading">ADDENDUM: How to use this License for your documents</h3>
-
-<p>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:
-</p>
-<div class="example">
-<pre class="example"> Copyright (C) <var>year</var> <var>your name</var>.
- Permission is granted to copy, distribute and/or modify this document
- under the terms of the GNU Free Documentation License, Version 1.3
- 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''.
-</pre></div>
-
-<p>If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
-replace the &ldquo;with&hellip;Texts.&rdquo; line with this:
-</p>
-<div class="example">
-<pre class="example"> with the Invariant Sections being <var>list their titles</var>, with
- the Front-Cover Texts being <var>list</var>, and with the Back-Cover Texts
- being <var>list</var>.
-</pre></div>
-
-<p>If you have Invariant Sections without Cover Texts, or some other
-combination of the three, merge those two alternatives to suit the
-situation.
-</p>
-<p>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.
