<P>GNU Free Documentation License Version 1.2, November 2002</P>
<P>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.</P>
<P>0. PREAMBLE</P>
<P>The purpose of this License is to make a manual, textbook, or
other functional and useful document &quot;free&quot; 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>
<P>This License is a kind of &quot;copyleft&quot;, 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>
<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.</P>
<P>1. APPLICABILITY AND DEFINITIONS</P>
<P>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 &quot;Document&quot;,
below, refers to any such manual or work. Any member of the public
is a licensee, and is addressed as &quot;you&quot;. You accept the
license if you copy, modify or distribute the work in a way requiring
permission under copyright law.</P>
<P>A &quot;Modified Version&quot; 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>
<P>A &quot;Secondary Section&quot; 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.</P>
<P>The &quot;Invariant Sections&quot; 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.</P>
<P>The &quot;Cover Texts&quot; 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.</P>
<P>A &quot;Transparent&quot; 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 &quot;Transparent&quot; is called &quot;Opaque&quot;.</P>
<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, 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.</P>
<P>The &quot;Title Page&quot; 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, &quot;Title
Page&quot; means the text near the most prominent appearance of the
work's title, preceding the beginning of the body of the text.</P>
<P>A section &quot;Entitled XYZ&quot; 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 &quot;Acknowledgements&quot;,
&quot;Dedications&quot;, &quot;Endorsements&quot;, or &quot;History&quot;.)
To &quot;Preserve the Title&quot; of such a section when you modify
the Document means that it remains a section &quot;Entitled XYZ&quot;
according to this definition.</P>
<P>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.</P>
<P>2. VERBATIM COPYING</P>
<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>
<P>You may also lend copies, under the same conditions stated above,
and you may publicly display copies.</P>
<P>3. COPYING IN QUANTITY</P>
<P>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.</P>
<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>
<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 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.</P>
<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.</P>
<P>4. MODIFICATIONS</P>
<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>
<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. 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 &quot;History&quot;, 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 &quot;History&quot; 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 &quot;History&quot; 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 &quot;Acknowledgements&quot;
or &quot;Dedications&quot;, 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 &quot;Endorsements&quot;. Such a section may not be included
in the Modified Version. N. Do not retitle any existing section to
be Entitled &quot;Endorsements&quot; or to conflict in title with
any Invariant Section. O. Preserve any Warranty Disclaimers.</P>
<P>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>
<P>You may add a section Entitled &quot;Endorsements&quot;, 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>
<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>
<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.</P>
<P>5. COMBINING DOCUMENTS</P>
<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, and that you preserve all their Warranty Disclaimers.</P>
<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>
<P>In the combination, you must combine any sections Entitled &quot;History&quot;
in the various original documents, forming one section Entitled &quot;History&quot;;
likewise combine any sections Entitled &quot;Acknowledgements&quot;,
and any sections Entitled &quot;Dedications&quot;. You must delete
all sections Entitled &quot;Endorsements&quot;.</P>
<P>6. COLLECTIONS OF DOCUMENTS</P>
<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>
<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.</P>
<P>7. AGGREGATION WITH INDEPENDENT WORKS</P>
<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, is called an &quot;aggregate&quot; 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.</P>
<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 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.</P>
<P>8. TRANSLATION</P>
<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, 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.</P>
<P>If a section in the Document is Entitled &quot;Acknowledgements&quot;,
&quot;Dedications&quot;, or &quot;History&quot;, the requirement
(section 4) to Preserve its Title (section 1) will typically require
changing the actual title.</P>
<P>9. TERMINATION</P>
<P>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.</P>
<P>10. FUTURE REVISIONS OF THIS LICENSE</P>
<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>
<P>Each version of the License is given a distinguishing version
number. If the Document specifies that a particular numbered version
of this License &quot;or any later version&quot; 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.</P>
<P>ADDENDUM: How to use this License for your documents</P>
<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:</P>
<P>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 &quot;GNU Free Documentation License&quot;.</P>
<P>If you have Invariant Sections, Front-Cover Texts and Back-Cover
Texts, replace the &quot;with...Texts.&quot; line with this:</P>
<P>with the Invariant Sections being LIST THEIR TITLES, with the
Front-Cover Texts being LIST, and with the Back-Cover Texts being
LIST.</P>
<P>If you have Invariant Sections without Cover Texts, or some other
combination of the three, merge those two alternatives to suit the
situation.</P>
<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. </P>
