   Version 1.3, 3 November 2008
               Copyright (c) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.

               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.


           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.

           The "publisher" means any person or entity that distributes copies
           of the Document to the public.

           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.


           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.


           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


           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

           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

           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 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.

           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.


           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."


           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


           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.

           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 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

           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 under this License.  Any attempt
           otherwise to copy, modify, sublicense, or distribute it is void,
           and will automatically terminate your rights under this License.

           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.

           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.

           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.


           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

           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

           Document does not specify a version number of this License, you may
           choose any version ever published (not as a draft) by the Free

       11. RELICENSING

           "Massive Multiauthor Collaboration Site" (or "MMC Site") 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 "Massive Multiauthor Collaboration" (or "MMC") contained in the
           site means any set of copyrightable works thus published on the MMC

           "CC-BY-SA" 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.

           "Incorporate" means to publish or republish a Document, in whole or
           in part, as part of another Document.

           An MMC is "eligible for relicensing" 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, \fIs0(1) had no
           cover texts or invariant sections, and (2) were thus incorporated
           prior to November 1, 2008.

           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.

   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

       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
