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.
|
|
|
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.
|
|
|
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 pe
rmission 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 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
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.
|
|
|
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.
