This is a copy of the GNU Free Documentation License, Version 1.2, also available online here; any discrepancies between this copy and the version there are accidental, and that document is definitive.

GNU Free Documentation License******************************

                     Version 1.2, November 2002    Copyright (C) 2000,2001,2002 Free Software Foundation, Inc.    59 Temple Place, Suite 330, Boston, MA  02111-1307, USA

    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.
