NAME
       gfdl - GNU Free Documentation License

DESCRIPTION
       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 non-
	   commercially.  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 docu-
	   ment 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 manu-
	   als providing the same freedoms that the software does.  But this License is not lim-
	   ited 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 prin-
	   cipally 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 Docu-
	   ment 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 Sec-
	   ondary 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 com-
	   posed of pixels) generic paint programs or (for drawings) some widely available draw-
	   ing editor, and that is suitable for input to text formatters or for automatic trans-
	   lation 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 Transpar-
	   ent.  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, @acronym{SGML} or @acronym{XML}
	   using a publicly available @acronym{DTD}, and standard-conforming simple @acro-
	   nym{HTML}, PostScript or @acronym{PDF} designed for human modification.  Examples of
	   transparent image formats include @acronym{PNG}, @acronym{XCF} and @acronym{JPG}.
	   Opaque formats include proprietary formats that can be read and edited only by propri-
	   etary word processors, @acronym{SGML} or @acronym{XML} for which the @acronym{DTD}
	   and/or processing tools are not generally available, and the machine-generated @acro-
	   nym{HTML}, PostScript or @acronym{PDF} produced by some word processors for output
	   purposes only.

	   The ``Title Page'' means, for a printed book, the title page itself, plus such follow-
	   ing 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 noncom-
	   mercially, 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 techni-
	   cal 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 pub-
	   lisher 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 con-
	   tinue 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 pro-
	   tocols 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 distri-
	   bution 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 edi-
	   tion 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 licens-
	   ing 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 per-
	       mission.

	   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 pub-
	       lic 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 Ver-
	       sion 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 pub-
	       lished at least four years before the Document itself, or if the original pub-
	       lisher 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 Modi-
	   fied 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.

       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 Invari-
	   ant 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 individu-
	   ally 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 Docu-
	   ment, then if the Document is less than one half of the entire aggregate, the Docu-
	   ment's Cover Texts may be placed on covers that bracket the Document within the aggre-
	   gate, 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 typi-
	   cally 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 Docu-
	   mentation 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.
