<li>PREAMBLE
 | 
						|
 | 
						|
     <p>The purpose of this License is to make a manual, textbook, or other
 | 
						|
written 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.
 | 
						|
 | 
						|
     <p>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.
 | 
						|
 | 
						|
     <p>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.
 | 
						|
 | 
						|
     <pre class="sp">
 | 
						|
     
 | 
						|
     </pre>
 | 
						|
     <li>APPLICABILITY AND DEFINITIONS
 | 
						|
 | 
						|
     <p>This License applies to any manual or other work that contains a
 | 
						|
notice placed by the copyright holder saying it can be distributed
 | 
						|
under the terms of this License.  The “Document”, below, refers to any
 | 
						|
such manual or work.  Any member of the public is a licensee, and is
 | 
						|
addressed as “you.”
 | 
						|
 | 
						|
     <p>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.
 | 
						|
 | 
						|
     <p>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.  (For example, 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.
 | 
						|
 | 
						|
     <p>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.
 | 
						|
 | 
						|
     <p>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.
 | 
						|
 | 
						|
     <p>A “Transparent” copy of the Document means a machine-readable copy,
 | 
						|
represented in a format whose specification is available to the
 | 
						|
general public, whose contents can be viewed and edited directly and
 | 
						|
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 has been designed to thwart or discourage
 | 
						|
subsequent modification by readers is not Transparent.  A copy that is
 | 
						|
not “Transparent” is called “Opaque.”
 | 
						|
 | 
						|
     <p>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 designed for human modification.  Opaque formats include
 | 
						|
PostScript, PDF, 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 produced by some word processors for output
 | 
						|
purposes only.
 | 
						|
 | 
						|
     <p>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.

						|

     <li>VERBATIM COPYING
 | 
						|
 | 
						|
     <p>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.
 | 
						|
 | 
						|
     <p>You may also lend copies, under the same conditions stated above, and
 | 
						|
you may publicly display copies.
 | 
						|
     <pre class="sp">
 | 
						|
     
 | 
						|
     </pre>
 | 
						|
     <li>COPYING IN QUANTITY
 | 
						|
 | 
						|
     <p>If you publish printed copies 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.
 | 
						|
 | 
						|
     <p>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.
 | 
						|
 | 
						|
     <p>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 publicly-accessible computer-network location containing a complete
 | 
						|
Transparent copy of the Document, free of added material, which the
 | 
						|
general network-using public has access to download anonymously at no
 | 
						|
charge using public-standard network protocols.  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.
 | 
						|
 | 
						|
     <p>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.
 | 
						|
     <pre class="sp">
 | 
						|
     
 | 
						|
     </pre>
 | 
						|
     <li>MODIFICATIONS
 | 
						|
 | 
						|
     <p>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:
 | 
						|
 | 
						|
     <p>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.<br>
 | 
						|
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 less than five).<br>
 | 
						|
C. State on the Title page the name of the publisher of the
 | 
						|
   Modified Version, as the publisher.<br>
 | 
						|
D. Preserve all the copyright notices of the Document.<br>
 | 
						|
E. Add an appropriate copyright notice for your modifications
 | 
						|
   adjacent to the other copyright notices.<br>
 | 
						|
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.<br>
 | 
						|
G. Preserve in that license notice the full lists of Invariant Sections
 | 
						|
   and required Cover Texts given in the Document's license notice.<br>
 | 
						|
H. Include an unaltered copy of this License.<br>
 | 
						|
I. Preserve the section entitled “History”, and 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.<br>
 | 
						|
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.<br>
 | 
						|
K. In any section entitled “Acknowledgements” or “Dedications”,
 | 
						|
   preserve the section's title, and preserve in the section all the
 | 
						|
   substance and tone of each of the contributor acknowledgements
 | 
						|
   and/or dedications given therein.<br>
 | 
						|
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.<br>
 | 
						|
M. Delete any section entitled “Endorsements.”  Such a section
 | 
						|
   may not be included in the Modified Version.<br>
 | 
						|
N. Do not retitle any existing section as “Endorsements”
 | 
						|
   or to conflict in title with any Invariant Section.<br>
 | 
						|
     <pre class="sp">
 | 
						|
     
 | 
						|
     </pre>
 | 
						|
     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.
 | 
						|
 | 
						|
     <p>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.
 | 
						|
 | 
						|
     <p>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.
 | 
						|
 | 
						|
     <p>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.

     <li>COMBINING DOCUMENTS
 | 
						|
 | 
						|
     <p>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.
 | 
						|
 | 
						|
     <p>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.
 | 
						|
 | 
						|
     <p>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.”

     <li>COLLECTIONS OF DOCUMENTS
 | 
						|

     <p>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.
 | 
						|
 | 
						|
     <p>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.

     <li>AGGREGATION WITH INDEPENDENT WORKS
 | 
						|
 | 
						|
     <p>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, does not as a whole count as a Modified Version
 | 
						|
of the Document, provided no compilation copyright is claimed for the
 | 
						|
compilation.  Such a compilation is called an “aggregate”, and this
 | 
						|
License does not apply to the other self-contained works thus compiled
 | 
						|
with the Document, on account of their being thus compiled, if they
 | 
						|
are not themselves derivative works of the Document.
 | 
						|
 | 
						|
     <p>If the Cover Text requirement of section 3 is applicable to these
 | 
						|
copies of the Document, then if the Document is less than one quarter
 | 
						|
of the entire aggregate, the Document's Cover Texts may be placed on
 | 
						|
covers that surround only the Document within the aggregate. 
 | 
						|
Otherwise they must appear on covers around the whole aggregate.

     <li>TRANSLATION
 | 
						|
 | 
						|
     <p>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 provided that you also include the
 | 
						|
original English version of this License.  In case of a disagreement
 | 
						|
between the translation and the original English version of this
 | 
						|
License, the original English version will prevail.

     <li>FUTURE REVISIONS OF THIS LICENSE
 | 
						|
 | 
						|
     <p>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/.
 | 
						|
 | 
						|
     <p>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.

<h3 class="unnumberedsec">ADDENDUM: How to use this License for your documents</h3>
 | 
						|
 | 
						|
<p>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:
 | 
						|
 | 
						|
<pre class="smallexample">     Copyright (C)  <var>year</var>  <var>your name</var>.
 | 
						|
     Permission is granted to copy, distribute and/or modify this document
 | 
						|
     under the terms of the GNU Free Documentation License, Version 1.1
 | 
						|
     or any later version published by the Free Software Foundation;
 | 
						|
     with the Invariant Sections being <var>list their titles</var>, with the
 | 
						|
     Front-Cover Texts being <var>list</var>, and with the Back-Cover Texts being <var>list</var>.
 | 
						|
     A copy of the license is included in the section entitled "GNU
 | 
						|
     Free Documentation License."
 | 
						|
</pre>
 | 
						|
   <p>If you have no Invariant Sections, write “with no Invariant Sections”
 | 
						|
instead of saying which ones are invariant.  If you have no
 | 
						|
Front-Cover Texts, write “no Front-Cover Texts” instead of
 | 
						|
“Front-Cover Texts being <var>list</var>”; likewise for Back-Cover Texts.
 | 
						|
 | 
						|
   <p>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.
