Version 1.1, March
2000
Copyright (C) 2000 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.
0. PREAMBLE
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.
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 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".
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. (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.
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.
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 "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".
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.
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.
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 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 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.
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 less than five).
- 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", 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.
- 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.
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.
- 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 as "Endorsements" or to
conflict in title with any Invariant Section.
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.
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, 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.
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.
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 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.
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.
