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.

<para>
|
|
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.</para>

1. APPLICABILITY AND DEFINITIONS
|
|
</bridgehead>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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".
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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

<para>
|

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.

may publicly display copies.

3. COPYING IN QUANTITY
|
|
</bridgehead>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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.

Document.

identical Invariant Sections may be replaced with a single copy. If there

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.

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

the Document within the aggregate, or the electronic equivalent of covers

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.

under the terms of the GNU Free Documentation License, Version 1.2 or

any later version published by the Free Software Foundation; with no

<para>
|
|
If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
|
|
replace the "with...Texts." line with this:
|
|
</para>
|
|
<blockquote>
|
|
<para>
|
|
with the Invariant Sections being LIST THEIR TITLES, with the
|
|
Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
|
|
</para>
|
|
</blockquote>
|
|
<para>
|
|
If you have Invariant Sections without Cover Texts, or some other
|
|
combination of the three, merge those two alternatives to suit the
|
|
situation.
