    Everyone is permitted to copy and distribute verbatim copies
    of this license document, but changing it is not allowed.
 0. PREAMBLE
    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.
    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.
    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.
 1. APPLICABILITY AND DEFINITIONS
    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.
    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.
    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.
    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.
    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.
    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".
    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.
    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.
    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.
    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.
 2. VERBATIM COPYING
    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.
    You may also lend copies, under the same conditions stated above,
    and you may publicly display copies.
 3. COPYING IN QUANTITY
    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.
    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.
    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.
    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.
 4. MODIFICATIONS
    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:
      A. 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.
      B. 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.
      C. State on the Title page the name of the publisher of the
         Modified Version, as the publisher.
      D. Preserve all the copyright notices of the Document.
      E. Add an appropriate copyright notice for your modifications
         adjacent to the other copyright notices.
      F. 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.
      G. Preserve in that license notice the full lists of Invariant
         Sections and required Cover Texts given in the Document's
         license notice.
      H. Include an unaltered copy of this License.
      I. 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.
      J. 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.
      K. 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.
      L. 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.
      M. Delete any section Entitled "Endorsements".  Such a section
         may not be included in the Modified Version.
      N. Do not retitle any existing section to be Entitled
         "Endorsements" or to conflict in title with any Invariant
         Section.
      O. Preserve any Warranty Disclaimers.
    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.
    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.
    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 o n 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.
    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.
 5. COMBINING DOCUMENTS
    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.
    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.
    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."
 6. COLLECTIONS OF DOCUMENTS
    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.
    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.
 7. AGGREGATION WITH INDEPENDENT WORKS
    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.
    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
    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.
    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.
 9. TERMINATION
    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.
10. FUTURE REVISIONS OF THIS LICENSE
    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/'.
    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.
ADDENDUM: How to use this License for your documents
====================================================
  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:
      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".
  If you have Invariant Sections, Front-Cover Texts and Back-Cover
  Texts, replace the "with...Texts." line with this:
        with the Invariant Sections being LIST THEIR TITLES, with
        the Front-Cover Texts being LIST, and with the Back-Cover Texts
        being LIST.
  If you have Invariant Sections without Cover Texts, or some other
  combination of the three, merge those two alternatives to suit the
  situation.
  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.
