PREAMBLE
|
17 |
|
|
|
18 |
|
|
The purpose of this License is to make a manual, textbook, or other
|
19 |
|
|
written document ``free'' in the sense of freedom: to assure everyone
|
20 |
|
|
the effective freedom to copy and redistribute it, with or without
|
21 |
|
|
modifying it, either commercially or noncommercially. Secondarily,
|
22 |
|
|
this License preserves for the author and publisher a way to get
|
23 |
|
|
credit for their work, while not being considered responsible for
|
24 |
|
|
modifications made by others.
|
25 |
|
|
|
26 |
|
|
This License is a kind of ``copyleft'', which means that derivative
|
27 |
|
|
works of the document must themselves be free in the same sense. It
|
28 |
|
|
complements the GNU General Public License, which is a copyleft
|
29 |
|
|
license designed for free software.
|
30 |
|
|
|
31 |
|
|
We have designed this License in order to use it for manuals for free
|
32 |
|
|
software, because free software needs free documentation: a free
|
33 |
|
|
program should come with manuals providing the same freedoms that the
|
34 |
|
|
software does. But this License is not limited to software manuals;
|
35 |
|
|
it can be used for any textual work, regardless of subject matter or
|
36 |
|
|
whether it is published as a printed book. We recommend this License
|
37 |
|
|
principally for works whose purpose is instruction or reference.

APPLICABILITY AND DEFINITIONS
|
42 |
|
|
|
43 |
|
|
This License applies to any manual or other work that contains a
|
44 |
|
|
notice placed by the copyright holder saying it can be distributed
|
45 |
|
|
under the terms of this License. The ``Document'', below, refers to any
|
46 |
|
|
such manual or work. Any member of the public is a licensee, and is
|
47 |
|
|
addressed as ``you.''
|
48 |
|
|
|
49 |
|
|
A ``Modified Version'' of the Document means any work containing the
|
50 |
|
|
Document or a portion of it, either copied verbatim, or with
|
51 |
|
|
modifications and/or translated into another language.
|
52 |
|
|
|
53 |
|
|
A ``Secondary Section'' is a named appendix or a front-matter section of
|
54 |
|
|
the Document that deals exclusively with the relationship of the
|
55 |
|
|
publishers or authors of the Document to the Document's overall subject
|
56 |
|
|
(or to related matters) and contains nothing that could fall directly
|
57 |
|
|
within that overall subject. (For example, if the Document is in part a
|
58 |
|
|
textbook of mathematics, a Secondary Section may not explain any
|
59 |
|
|
mathematics.) The relationship could be a matter of historical
|
60 |
|
|
connection with the subject or with related matters, or of legal,
|
61 |
|
|
commercial, philosophical, ethical or political position regarding
|
62 |
|
|
them.
|
63 |
|
|
|
64 |
|
|
The ``Invariant Sections'' are certain Secondary Sections whose titles
|
65 |
|
|
are designated, as being those of Invariant Sections, in the notice
|
66 |
|
|
that says that the Document is released under this License.
|
67 |
|
|
|
68 |
|
|
The ``Cover Texts'' are certain short passages of text that are listed,
|
69 |
|
|
as Front-Cover Texts or Back-Cover Texts, in the notice that says that
|
70 |
|
|
the Document is released under this License.
|
71 |
|
|
|
72 |
|
|
A ``Transparent'' copy of the Document means a machine-readable copy,
|
73 |
|
|
represented in a format whose specification is available to the
|
74 |
|
|
general public, whose contents can be viewed and edited directly and
|
75 |
|
|
straightforwardly with generic text editors or (for images composed of
|
76 |
|
|
pixels) generic paint programs or (for drawings) some widely available
|
77 |
|
|
drawing editor, and that is suitable for input to text formatters or
|
78 |
|
|
for automatic translation to a variety of formats suitable for input
|
79 |
|
|
to text formatters. A copy made in an otherwise Transparent file
|
80 |
|
|
format whose markup has been designed to thwart or discourage
|
81 |
|
|
subsequent modification by readers is not Transparent. A copy that is
|
82 |
|
|
not ``Transparent'' is called ``Opaque.''
|
83 |
|
|
|
84 |
|
|
Examples of suitable formats for Transparent copies include plain
|
85 |
|
|
ASCII without markup, Texinfo input format, LaTeX input format, SGML
|
86 |
|
|
or XML using a publicly available DTD, and standard-conforming simple
|
87 |
|
|
HTML designed for human modification. Opaque formats include
|
88 |
|
|
PostScript, PDF, proprietary formats that can be read and edited only
|
89 |
|
|
by proprietary word processors, SGML or XML for which the DTD and/or
|
90 |
|
|
processing tools are not generally available, and the
|
91 |
|
|
machine-generated HTML produced by some word processors for output
|
92 |
|
|
purposes only.
|
93 |
|
|
|
94 |
|
|
The ``Title Page'' means, for a printed book, the title page itself,
|
95 |
|
|
plus such following pages as are needed to hold, legibly, the material
|
96 |
|
|
this License requires to appear in the title page. For works in
|
97 |
|
|
formats which do not have any title page as such, ``Title Page'' means
|
98 |
|
|
the text near the most prominent appearance of the work's title,
|
99 |
|
|
preceding the beginning of the body of the text.

VERBATIM COPYING
|
103 |
|
|
|
104 |
|
|
You may copy and distribute the Document in any medium, either
|
105 |
|
|
commercially or noncommercially, provided that this License, the
|
106 |
|
|
copyright notices, and the license notice saying this License applies
|
107 |
|
|
to the Document are reproduced in all copies, and that you add no other
|
108 |
|
|
conditions whatsoever to those of this License. You may not use
|
109 |
|
|
technical measures to obstruct or control the reading or further
|
110 |
|
|
copying of the copies you make or distribute. However, you may accept
|
111 |
|
|
compensation in exchange for copies. If you distribute a large enough
|
112 |
|
|
number of copies you must also follow the conditions in section 3.
|
113 |
|
|
|
114 |
|
|
You may also lend copies, under the same conditions stated above, and
|
115 |
|
|
you may publicly display copies.

COPYING IN QUANTITY
|
119 |
|
|
|
120 |
|
|
If you publish printed copies of the Document numbering more than 100,
|
121 |
|
|
and the Document's license notice requires Cover Texts, you must enclose
|
122 |
|
|
the copies in covers that carry, clearly and legibly, all these Cover
|
123 |
|
|
Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
|
124 |
|
|
the back cover. Both covers must also clearly and legibly identify
|
125 |
|
|
you as the publisher of these copies. The front cover must present
|
126 |
|
|
the full title with all words of the title equally prominent and
|
127 |
|
|
visible. You may add other material on the covers in addition.
|
128 |
|
|
Copying with changes limited to the covers, as long as they preserve
|
129 |
|
|
the title of the Document and satisfy these conditions, can be treated
|
130 |
|
|
as verbatim copying in other respects.
|
131 |
|
|
|
132 |
|
|
If the required texts for either cover are too voluminous to fit
|
133 |
|
|
legibly, you should put the first ones listed (as many as fit
|
134 |
|
|
reasonably) on the actual cover, and continue the rest onto adjacent
|
135 |
|
|
pages.
|
136 |
|
|
|
137 |
|
|
If you publish or distribute Opaque copies of the Document numbering
|
138 |
|
|
more than 100, you must either include a machine-readable Transparent
|
139 |
|
|
copy along with each Opaque copy, or state in or with each Opaque copy
|
140 |
|
|
a publicly-accessible computer-network location containing a complete
|
141 |
|
|
Transparent copy of the Document, free of added material, which the
|
142 |
|
|
general network-using public has access to download anonymously at no
|
143 |
|
|
charge using public-standard network protocols. If you use the latter
|
144 |
|
|
option, you must take reasonably prudent steps, when you begin
|
145 |
|
|
distribution of Opaque copies in quantity, to ensure that this
|
146 |
|
|
Transparent copy will remain thus accessible at the stated location
|
147 |
|
|
until at least one year after the last time you distribute an Opaque
|
148 |
|
|
copy (directly or through your agents or retailers) of that edition to
|
149 |
|
|
the public.
|
150 |
|
|
|
151 |
|
|
It is requested, but not required, that you contact the authors of the
|
152 |
|
|
Document well before redistributing any large number of copies, to give
|
153 |
|
|
them a chance to provide you with an updated version of the Document.

MODIFICATIONS

158 |
|
|
You may copy and distribute a Modified Version of the Document under
|
159 |
|
|
the conditions of sections 2 and 3 above, provided that you release
|
160 |
|
|
the Modified Version under precisely this License, with the Modified
|
161 |
|
|
Version filling the role of the Document, thus licensing distribution
|
162 |
|
|
and modification of the Modified Version to whoever possesses a copy
|
163 |
|
|
of it. In addition, you must do these things in the Modified Version:
|
164 |
|
|
|
165 |
|
|
A. Use in the Title Page (and on the covers, if any) a title distinct
|
166 |
|
|
from that of the Document, and from those of previous versions
|
167 |
|
|
(which should, if there were any, be listed in the History section
|
168 |
|
|
of the Document). You may use the same title as a previous version
|
169 |
|
|
if the original publisher of that version gives permission.@*
|
170 |
|
|
B. List on the Title Page, as authors, one or more persons or entities
|
171 |
|
|
responsible for authorship of the modifications in the Modified
|
172 |
|
|
Version, together with at least five of the principal authors of the
|
173 |
|
|
Document (all of its principal authors, if it has less than five).@*
|
174 |
|
|
C. State on the Title page the name of the publisher of the
|
175 |
|
|
Modified Version, as the publisher.@*
|
176 |
|
|
D. Preserve all the copyright notices of the Document.@*
|
177 |
|
|
E. Add an appropriate copyright notice for your modifications
|
178 |
|
|
adjacent to the other copyright notices.@*
|
179 |
|
|
F. Include, immediately after the copyright notices, a license notice
|
180 |
|
|
giving the public permission to use the Modified Version under the
|
181 |
|
|
terms of this License, in the form shown in the Addendum below.@*
|
182 |
|
|
G. Preserve in that license notice the full lists of Invariant Sections
|
183 |
|
|
and required Cover Texts given in the Document's license notice.@*
|
184 |
|
|
H. Include an unaltered copy of this License.@*
|
185 |
|
|
I. Preserve the section entitled ``History'', and its title, and add to
|
186 |
|
|
it an item stating at least the title, year, new authors, and
|
187 |
|
|
publisher of the Modified Version as given on the Title Page. If
|
188 |
|
|
there is no section entitled ``History'' in the Document, create one
|
189 |
|
|
stating the title, year, authors, and publisher of the Document as
|
190 |
|
|
given on its Title Page, then add an item describing the Modified
|
191 |
|
|
Version as stated in the previous sentence.@*
|
192 |
|
|
J. Preserve the network location, if any, given in the Document for
|
193 |
|
|
public access to a Transparent copy of the Document, and likewise
|
194 |
|
|
the network locations given in the Document for previous versions
|
195 |
|
|
it was based on. These may be placed in the ``History'' section.
|
196 |
|
|
You may omit a network location for a work that was published at
|
197 |
|
|
least four years before the Document itself, or if the original
|
198 |
|
|
publisher of the version it refers to gives permission.@*
|
199 |
|
|
K. In any section entitled ``Acknowledgements'' or ``Dedications'',
|
200 |
|
|
preserve the section's title, and preserve in the section all the
|
201 |
|
|
substance and tone of each of the contributor acknowledgements
|
202 |
|
|
and/or dedications given therein.@*
|
203 |
|
|
L. Preserve all the Invariant Sections of the Document,
|
204 |
|
|
unaltered in their text and in their titles. Section numbers
|
205 |
|
|
or the equivalent are not considered part of the section titles.@*
|
206 |
|
|
M. Delete any section entitled ``Endorsements.'' Such a section
|
207 |
|
|
may not be included in the Modified Version.@*
|
208 |
|
|
N. Do not retitle any existing section as ``Endorsements''
|
209 |
|
|
or to conflict in title with any Invariant Section.@*
|
210 |
|
|
@sp 1
|
211 |
|
|
If the Modified Version includes new front-matter sections or
|
212 |
|
|
appendices that qualify as Secondary Sections and contain no material
|
213 |
|
|
copied from the Document, you may at your option designate some or all
|
214 |
|
|
of these sections as invariant. To do this, add their titles to the
|
215 |
|
|
list of Invariant Sections in the Modified Version's license notice.
|
216 |
|
|
These titles must be distinct from any other section titles.
|
217 |
|
|
|
218 |
|
|
You may add a section entitled ``Endorsements'', provided it contains
|
219 |
|
|
nothing but endorsements of your Modified Version by various
|
220 |
|
|
parties--for example, statements of peer review or that the text has
|
221 |
|
|
been approved by an organization as the authoritative definition of a
|
222 |
|
|
standard.
|
223 |
|
|
|
224 |
|
|
You may add a passage of up to five words as a Front-Cover Text, and a
|
225 |
|
|
passage of up to 25 words as a Back-Cover Text, to the end of the list
|
226 |
|
|
of Cover Texts in the Modified Version. Only one passage of
|
227 |
|
|
Front-Cover Text and one of Back-Cover Text may be added by (or
|
228 |
|
|
through arrangements made by) any one entity. If the Document already
|
229 |
|
|
includes a cover text for the same cover, previously added by you or
|
230 |
|
|
by arrangement made by the same entity you are acting on behalf of,
|
231 |
|
|
you may not add another; but you may replace the old one, on explicit
|
232 |
|
|
permission from the previous publisher that added the old one.
|
233 |
|
|
|
234 |
|
|
The author(s) and publisher(s) of the Document do not by this License
|
235 |
|
|
give permission to use their names for publicity for or to assert or
|
236 |
|
|
imply endorsement of any Modified Version.

COMBINING DOCUMENTS
|

You may combine the Document with other documents released under this
|
242 |
|
|
License, under the terms defined in section 4 above for modified
|
243 |
|
|
versions, provided that you include in the combination all of the

244 |
|
|
Invariant Sections of all of the original documents, unmodified, and
|
245 |
|
|
list them all as Invariant Sections of your combined work in its
|
246 |
|
|
license notice.
|
247 |
|
|
|
248 |
|
|
The combined work need only contain one copy of this License, and
|
249 |
|
|
multiple identical Invariant Sections may be replaced with a single
|
250 |
|
|
copy. If there are multiple Invariant Sections with the same name but
|
251 |
|
|
different contents, make the title of each such section unique by
|
252 |
|
|
adding at the end of it, in parentheses, the name of the original
|
253 |
|
|
author or publisher of that section if known, or else a unique number.
|
254 |
|
|
Make the same adjustment to the section titles in the list of
|
255 |
|
|
Invariant Sections in the license notice of the combined work.
|
256 |
|
|
|
257 |
|
|
In the combination, you must combine any sections entitled ``History''
|
258 |
|
|
in the various original documents, forming one section entitled
|
259 |
|
|
``History''; likewise combine any sections entitled ``Acknowledgements'',
|
260 |
|
|
and any sections entitled ``Dedications.'' You must delete all sections
|
261 |
|
|
entitled ``Endorsements.''

You may make a collection consisting of the Document and other documents

299 |
|
|
distribute translations of the Document under the terms of section 4.
|
300 |
|
|
Replacing Invariant Sections with translations requires special
|
301 |
|
|
permission from their copyright holders, but you may include
|
302 |
|
|
translations of some or all Invariant Sections in addition to the
|
303 |
|
|
original versions of these Invariant Sections. You may include a
|
304 |
|
|
translation of this License provided that you also include the
|
305 |
|
|
original English version of this License. In case of a disagreement
|
306 |
|
|
between the translation and the original English version of this
|
307 |
|
|
License, the original English version will prevail.

FUTURE REVISIONS OF THIS LICENSE
|
322 |
|
|
|
323 |
|
|
The Free Software Foundation may publish new, revised versions
|
324 |
|
|
of the GNU Free Documentation License from time to time. Such new
|
325 |
|
|
versions will be similar in spirit to the present version, but may
|
326 |
|
|
differ in detail to address new problems or concerns. See
|
327 |
|
|
http://www.gnu.org/copyleft/.
|
328 |
|
|
|
329 |
|
|
Each version of the License is given a distinguishing version number.
|
330 |
|
|
If the Document specifies that a particular numbered version of this
|
331 |
|
|
License ``or any later version'' applies to it, you have the option of
|
332 |
|
|
following the terms and conditions either of that specified version or
|
333 |
|
|
of any later version that has been published (not as a draft) by the
|
334 |
|
|
Free Software Foundation. If the Document does not specify a version
|
335 |
|
|
number of this License, you may choose any version ever published (not
|
336 |
|
|
as a draft) by the Free Software Foundation.

|
343 |
|
|
the License in the document and put the following copyright and
|
344 |
|

Permission is granted to copy, distribute and/or modify this document
|
350 |
|
|
under the terms of the GNU Free Documentation License, Version 1.1
|
351 |
|
|
or any later version published by the Free Software Foundation;
|
352 |
|
|
with the Invariant Sections being @var{list their titles}, with the
|
353 |
|
|
Front-Cover Texts being @var{list}, and with the Back-Cover Texts being @var{list}.

If you have no Invariant Sections, write ``with no Invariant Sections''
|
360 |
|
|
instead of saying which ones are invariant. If you have no
|
361 |
|
|
Front-Cover Texts, write ``no Front-Cover Texts'' instead of
|
362 |
|
|
``Front-Cover Texts being @var{list}''; likewise for Back-Cover Texts.
|
363 |
|
|
|
364 |
|
|
If your document contains nontrivial examples of program code, we
|
365 |
|
|
recommend releasing these examples in parallel under your choice of
|
366 |
|
|
free software license, such as the GNU General Public License,
|
367 |
|
|
to permit their use in free software.
