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.
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 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. |
