    <title>PREAMBLE</title>

    <para>The purpose of this License is to make a manual, textbook,
    or other written 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>
  </sect1>

  <sect1 label="1">
    <title>APPLICABILITY AND DEFINITIONS</title>

    <para>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 "Document",
    below, refers to any such manual or work.  Any member of the
    public is a licensee, and is addressed as "you".</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.
    (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>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.</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.</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, 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
    "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 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>

    <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>
  </sect1>

  <sect1 label="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>
  </sect1>

  <sect1 label="3">
    <title>COPYING IN QUANTITY</title>

    <para>If you publish printed copies 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 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.</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>
  </sect1>

  <sect1 label="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 numeration="upperalpha">
      <listitem><para>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.</para>
      </listitem>

      <listitem><para>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 less than
      five).</para>
      </listitem>

      <listitem><para>State on the Title page
