    0. PREAMBLE
  </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 xml: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 xml: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 xml: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 xml:id="Modifications" renderas="sect1">
    4. MODIFICATIONS
  </bridgehead>
  <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:

        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

  <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

  <bridgehead xml:id="Combining" renderas="sect1">
    5. COMBINING DOCUMENTS
  </bridgehead>
  <para>
    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.
  </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

    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>
  <bridgehead xml: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.
  </para>
  <bridgehead xml:id="Translation" renderas="sect1">
    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.
