NAME
       gfdl - GNU Free Documentation License

DESCRIPTION
       GNU Free	Documentation License

       Version 1.3, 3 November 2008

	       Copyright (c) 2000, 2001, 2002, 2007, 2008 Free Software	Foundation, Inc.
	       E<lt>B<http://fsf.org/>E<gt>

	       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.

	   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.

       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 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	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	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
	   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	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.

       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.	 If the	Document specifies that	a proxy	can
	   decide which	future versions	of this	License	can be used, that
	   proxy's public statement of acceptance of a version permanently
	   authorizes you to choose that version for the Document.

       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
	   site.

	   "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, (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
       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	1.3
		 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.
