The programs currently being distributed that relate to preview-latex
2019
include lisp files for Emacs and style files for LaTeX. These programs
2020
are "free"; this means that everyone is free to use them and free to
2021
redistribute them on a free basis. The preview-latex related programs
2022
are not in the public domain; they are copyrighted and there are
2023
restrictions on their distribution, but these restrictions are designed
2024
to permit everything that a good cooperating citizen would want to do.
2025
What is not allowed is to try to prevent others from further sharing
2026
any version of these programs that they might get from you.
2028
Specifically, we want to make sure that you have the right to give
2029
away copies of the programs that relate to preview-latex, that you
2030
receive source code or else can get it if you want it, that you can
2031
change these programs or use pieces of them in new free programs, and
2032
that you know you can do these things.
2034
To make sure that everyone has such rights, we have to forbid you to
2035
deprive anyone else of these rights. For example, if you distribute
2036
copies of the preview-latex related programs, you must give the
2037
recipients all the rights that you have. You must make sure that they,
2038
too, receive or can get the source code. And you must tell them their
2041
Also, for our own protection, we must make certain that everyone
2042
finds out that there is no warranty for the programs that relate to
2043
preview-latex. If these programs are modified by someone else and
2044
passed on, we want their recipients to know that what they have is not
2045
what we distributed, so that any problems introduced by others will not
2046
reflect on our reputation.
2048
The precise conditions of the licenses for the programs currently
2049
being distributed that relate to preview-latex are found in the General
2050
Public Licenses that accompany them.

==================================
2022
Version 1.2, November 2002

51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA
2027
Everyone is permitted to copy and distribute verbatim copies
2028
of this license document, but changing it is not allowed.
2032
The purpose of this License is to make a manual, textbook, or other
2033
functional and useful document "free" in the sense of freedom: to
2034
assure everyone the effective freedom to copy and redistribute it,
2035
with or without modifying it, either commercially or
2036
noncommercially. Secondarily, this License preserves for the
2037
author and publisher a way to get credit for their work, while not
2038
being considered responsible for modifications made by others.
2040
This License is a kind of "copyleft", which means that derivative
2041
works of the document must themselves be free in the same sense.
2042
It complements the GNU General Public License, which is a copyleft
2043
license designed for free software.
2045
We have designed this License in order to use it for manuals for
2046
free software, because free software needs free documentation: a
2047
free program should come with manuals providing the same freedoms
2048
that the software does. But this License is not limited to
2049
software manuals; it can be used for any textual work, regardless
2050
of subject matter or whether it is published as a printed book.
2051
We recommend this License principally for works whose purpose is
2052
instruction or reference.
2054
1. APPLICABILITY AND DEFINITIONS
2056
This License applies to any manual or other work, in any medium,
2057
that contains a notice placed by the copyright holder saying it
2058
can be distributed under the terms of this License. Such a notice
2059
grants a world-wide, royalty-free license, unlimited in duration,
2060
to use that work under the conditions stated herein. The
2061
"Document", below, refers to any such manual or work. Any member
2062
of the public is a licensee, and is addressed as "you". You
2063
accept the license if you copy, modify or distribute the work in a
2064
way requiring permission under copyright law.
2066
A "Modified Version" of the Document means any work containing the
2067
Document or a portion of it, either copied verbatim, or with
2068
modifications and/or translated into another language.
2070
A "Secondary Section" is a named appendix or a front-matter section
2071
of the Document that deals exclusively with the relationship of the
2072
publishers or authors of the Document to the Document's overall
2073
subject (or to related matters) and contains nothing that could
2074
fall directly within that overall subject. (Thus, if the Document
2075
is in part a textbook of mathematics, a Secondary Section may not
2076
explain any mathematics.) The relationship could be a matter of
2077
historical connection with the subject or with related matters, or
2078
of legal, commercial, philosophical, ethical or political position
2081
The "Invariant Sections" are certain Secondary Sections whose
2082
titles are designated, as being those of Invariant Sections, in
2083
the notice that says that the Document is released under this
2084
License. If a section does not fit the above definition of
2085
Secondary then it is not allowed to be designated as Invariant.
2086
The Document may contain zero Invariant Sections. If the Document
2087
does not identify any Invariant Sections then there are none.
2089
The "Cover Texts" are certain short passages of text that are
2090
listed, as Front-Cover Texts or Back-Cover Texts, in the notice
2091
that says that the Document is released under this License. A
2092
Front-Cover Text may be at most 5 words, and a Back-Cover Text may
2093
be at most 25 words.
2095
A "Transparent" copy of the Document means a machine-readable copy,
2096
represented in a format whose specification is available to the
2097
general public, that is suitable for revising the document
2098
straightforwardly with generic text editors or (for images
2099
composed of pixels) generic paint programs or (for drawings) some
2100
widely available drawing editor, and that is suitable for input to
2101
text formatters or for automatic translation to a variety of
2102
formats suitable for input to text formatters. A copy made in an
2103
otherwise Transparent file format whose markup, or absence of
2104
markup, has been arranged to thwart or discourage subsequent
2105
modification by readers is not Transparent. An image format is
2106
not Transparent if used for any substantial amount of text. A
2107
copy that is not "Transparent" is called "Opaque".
2109
Examples of suitable formats for Transparent copies include plain
2110
ASCII without markup, Texinfo input format, LaTeX input format,
2111
SGML or XML using a publicly available DTD, and
2112
standard-conforming simple HTML, PostScript or PDF designed for
2113
human modification. Examples of transparent image formats include
2114
PNG, XCF and JPG. Opaque formats include proprietary formats that
2115
can be read and edited only by proprietary word processors, SGML or
2116
XML for which the DTD and/or processing tools are not generally
2117
available, and the machine-generated HTML, PostScript or PDF
2118
produced by some word processors for output purposes only.
2120
The "Title Page" means, for a printed book, the title page itself,
2121
plus such following pages as are needed to hold, legibly, the
2122
material this License requires to appear in the title page. For
2123
works in formats which do not have any title page as such, "Title
2124
Page" means the text near the most prominent appearance of the
2125
work's title, preceding the beginning of the body of the text.
2127
A section "Entitled XYZ" means a named subunit of the Document
2128
whose title either is precisely XYZ or contains XYZ in parentheses
2129
following text that translates XYZ in another language. (Here XYZ
2130
stands for a specific section name mentioned below, such as
2131
"Acknowledgements", "Dedications", "Endorsements", or "History".)
2132
To "Preserve the Title" of such a section when you modify the
2133
Document means that it remains a section "Entitled XYZ" according
2136
The Document may include Warranty Disclaimers next to the notice
2137
which states that this License applies to the Document. These
2138
Warranty Disclaimers are considered to be included by reference in
2139
this License, but only as regards disclaiming warranties: any other
2140
implication that these Warranty Disclaimers may have is void and
2141
has no effect on the meaning of this License.
2145
You may copy and distribute the Document in any medium, either
2146
commercially or noncommercially, provided that this License, the
2147
copyright notices, and the license notice saying this License
2148
applies to the Document are reproduced in all copies, and that you
2149
add no other conditions whatsoever to those of this License. You
2150
may not use technical measures to obstruct or control the reading
2151
or further copying of the copies you make or distribute. However,
2152
you may accept compensation in exchange for copies. If you
2153
distribute a large enough number of copies you must also follow
2154
the conditions in section 3.
2156
You may also lend copies, under the same conditions stated above,
2157
and you may publicly display copies.
2159
3. COPYING IN QUANTITY
2161
If you publish printed copies (or copies in media that commonly
2162
have printed covers) of the Document, numbering more than 100, and
2163
the Document's license notice requires Cover Texts, you must
2164
enclose the copies in covers that carry, clearly and legibly, all
2165
these Cover Texts: Front-Cover Texts on the front cover, and
2166
Back-Cover Texts on the back cover. Both covers must also clearly
2167
and legibly identify you as the publisher of these copies. The
2168
front cover must present the full title with all words of the
2169
title equally prominent and visible. You may add other material
2170
on the covers in addition. Copying with changes limited to the
2171
covers, as long as they preserve the title of the Document and
2172
satisfy these conditions, can be treated as verbatim copying in
2175
If the required texts for either cover are too voluminous to fit
2176
legibly, you should put the first ones listed (as many as fit
2177
reasonably) on the actual cover, and continue the rest onto
2180
If you publish or distribute Opaque copies of the Document
2181
numbering more than 100, you must either include a
2182
machine-readable Transparent copy along with each Opaque copy, or
2183
state in or with each Opaque copy a computer-network location from
2184
which the general network-using public has access to download
2185
using public-standard network protocols a complete Transparent
2186
copy of the Document, free of added material. If you use the
2187
latter option, you must take reasonably prudent steps, when you
2188
begin distribution of Opaque copies in quantity, to ensure that
2189
this Transparent copy will remain thus accessible at the stated
2190
location until at least one year after the last time you
2191
distribute an Opaque copy (directly or through your agents or
2192
retailers) of that edition to the public.
2194
It is requested, but not required, that you contact the authors of
2195
the Document well before redistributing any large number of
2196
copies, to give them a chance to provide you with an updated
2197
version of the Document.
2201
You may copy and distribute a Modified Version of the Document
2202
under the conditions of sections 2 and 3 above, provided that you
2203
release the Modified Version under precisely this License, with
2204
the Modified Version filling the role of the Document, thus
2205
licensing distribution and modification of the Modified Version to
2206
whoever possesses a copy of it. In addition, you must do these
2207
things in the Modified Version:
2209
A. Use in the Title Page (and on the covers, if any) a title
2210
distinct from that of the Document, and from those of
2211
previous versions (which should, if there were any, be listed
2212
in the History section of the Document). You may use the
2213
same title as a previous version if the original publisher of
2214
that version gives permission.
2216
B. List on the Title Page, as authors, one or more persons or
2217
entities responsible for authorship of the modifications in
2218
the Modified Version, together with at least five of the
2219
principal authors of the Document (all of its principal
2220
authors, if it has fewer than five), unless they release you
2221
from this requirement.
2223
C. State on the Title page the name of the publisher of the
2224
Modified Version, as the publisher.
2226
D. Preserve all the copyright notices of the Document.
2228
E. Add an appropriate copyright notice for your modifications
2229
adjacent to the other copyright notices.
2231
F. Include, immediately after the copyright notices, a license
2232
notice giving the public permission to use the Modified
2233
Version under the terms of this License, in the form shown in
2236
G. Preserve in that license notice the full lists of Invariant
2237
Sections and required Cover Texts given in the Document's
2240
H. Include an unaltered copy of this License.
2242
I. Preserve the section Entitled "History", Preserve its Title,
2243
and add to it an item stating at least the title, year, new
2244
authors, and publisher of the Modified Version as given on
2245
the Title Page. If there is no section Entitled "History" in
2246
the Document, create one stating the title, year, authors,
2247
and publisher of the Document as given on its Title Page,
2248
then add an item describing the Modified Version as stated in
2249
the previous sentence.
2251
J. Preserve the network location, if any, given in the Document
2252
for public access to a Transparent copy of the Document, and
2253
likewise the network locations given in the Document for
2254
previous versions it was based on. These may be placed in
2255
the "History" section. You may omit a network location for a
2256
work that was published at least four years before the
2257
Document itself, or if the original publisher of the version
2258
it refers to gives permission.
2260
K. For any section Entitled "Acknowledgements" or "Dedications",
2261
Preserve the Title of the section, and preserve in the
2262
section all the substance and tone of each of the contributor
2263
acknowledgements and/or dedications given therein.
2265
L. Preserve all the Invariant Sections of the Document,
2266
unaltered in their text and in their titles. Section numbers
2267
or the equivalent are not considered part of the section
2270
M. Delete any section Entitled "Endorsements". Such a section
2271
may not be included in the Modified Version.
2273
N. Do not retitle any existing section to be Entitled
2274
"Endorsements" or to conflict in title with any Invariant
2277
O. Preserve any Warranty Disclaimers.
2279
If the Modified Version includes new front-matter sections or
2280
appendices that qualify as Secondary Sections and contain no
2281
material copied from the Document, you may at your option
2282
designate some or all of these sections as invariant. To do this,
2283
add their titles to the list of Invariant Sections in the Modified
2284
Version's license notice. These titles must be distinct from any
2285
other section titles.
2287
You may add a section Entitled "Endorsements", provided it contains
2288
nothing but endorsements of your Modified Version by various
2289
parties--for example, statements of peer review or that the text
2290
has been approved by an organization as the authoritative
2291
definition of a standard.
2293
You may add a passage of up to five words as a Front-Cover Text,
2294
and a passage of up to 25 words as a Back-Cover Text, to the end
2295
of the list of Cover Texts in the Modified Version. Only one
2296
passage of Front-Cover Text and one of Back-Cover Text may be
2297
added by (or through arrangements made by) any one entity. If the
2298
Document already includes a cover text for the same cover,
2299
previously added by you or by arrangement made by the same entity
2300
you are acting on behalf of, you may not add another; but you may
2301
replace the old one, on explicit permission from the previous
2302
publisher that added the old one.
2304
The author(s) and publisher(s) of the Document do not by this
2305
License give permission to use their names for publicity for or to
2306
assert or imply endorsement of any Modified Version.
2308
5. COMBINING DOCUMENTS
2310
You may combine the Document with other documents released under
2311
this License, under the terms defined in section 4 above for
2312
modified versions, provided that you include in the combination
2313
all of the Invariant Sections of all of the original documents,
2314
unmodified, and list them all as Invariant Sections of your
2315
combined work in its license notice, and that you preserve all
2316
their Warranty Disclaimers.
2318
The combined work need only contain one copy of this License, and
2319
multiple identical Invariant Sections may be replaced with a single
2320
copy. If there are multiple Invariant Sections with the same name
2321
but different contents, make the title of each such section unique
2322
by adding at the end of it, in parentheses, the name of the
2323
original author or publisher of that section if known, or else a
2324
unique number. Make the same adjustment to the section titles in
2325
the list of Invariant Sections in the license notice of the
2328
In the combination, you must combine any sections Entitled
2329
"History" in the various original documents, forming one section
2330
Entitled "History"; likewise combine any sections Entitled
2331
"Acknowledgements", and any sections Entitled "Dedications". You
2332
must delete all sections Entitled "Endorsements."
2334
6. COLLECTIONS OF DOCUMENTS
2336
You may make a collection consisting of the Document and other
2337
documents released under this License, and replace the individual
2338
copies of this License in the various documents with a single copy
2339
that is included in the collection, provided that you follow the
2340
rules of this License for verbatim copying of each of the
2341
documents in all other respects.
2343
You may extract a single document from such a collection, and
2344
distribute it individually under this License, provided you insert
2345
a copy of this License into the extracted document, and follow
2346
this License in all other respects regarding verbatim copying of
2349
7. AGGREGATION WITH INDEPENDENT WORKS
2351
A compilation of the Document or its derivatives with other
2352
separate and independent documents or works, in or on a volume of
2353
a storage or distribution medium, is called an "aggregate" if the
2354
copyright resulting from the compilation is not used to limit the
2355
legal rights of the compilation's users beyond what the individual
2356
works permit. When the Document is included in an aggregate, this
2357
License does not apply to the other works in the aggregate which
2358
are not themselves derivative works of the Document.
2360
If the Cover Text requirement of section 3 is applicable to these
2361
copies of the Document, then if the Document is less than one half
2362
of the entire aggregate, the Document's Cover Texts may be placed
2363
on covers that bracket the Document within the aggregate, or the
2364
electronic equivalent of covers if the Document is in electronic
2365
form. Otherwise they must appear on printed covers that bracket
2366
the whole aggregate.
2370
Translation is considered a kind of modification, so you may
2371
distribute translations of the Document under the terms of section
2372
4. Replacing Invariant Sections with translations requires special
2373
permission from their copyright holders, but you may include
2374
translations of some or all Invariant Sections in addition to the
2375
original versions of these Invariant Sections. You may include a
2376
translation of this License, and all the license notices in the
2377
Document, and any Warranty Disclaimers, provided that you also
2378
include the original English version of this License and the
2379
original versions of those notices and disclaimers. In case of a
2380
disagreement between the translation and the original version of
2381
this License or a notice or disclaimer, the original version will
2384
If a section in the Document is Entitled "Acknowledgements",
2385
"Dedications", or "History", the requirement (section 4) to
2386
Preserve its Title (section 1) will typically require changing the
2391
You may not copy, modify, sublicense, or distribute the Document
2392
except as expressly provided for under this License. Any other
2393
attempt to copy, modify, sublicense or distribute the Document is
2394
void, and will automatically terminate your rights under this
2395
License. However, parties who have received copies, or rights,
2396
from you under this License will not have their licenses
2397
terminated so long as such parties remain in full compliance.
2399
10. FUTURE REVISIONS OF THIS LICENSE
2401
The Free Software Foundation may publish new, revised versions of
2402
the GNU Free Documentation License from time to time. Such new
2403
versions will be similar in spirit to the present version, but may
2404
differ in detail to address new problems or concerns. See
2405
`http://www.gnu.org/copyleft/'.
2407
Each version of the License is given a distinguishing version
2408
number. If the Document specifies that a particular numbered
2409
version of this License "or any later version" applies to it, you
2410
have the option of following the terms and conditions either of
2411
that specified version or of any later version that has been
2412
published (not as a draft) by the Free Software Foundation. If
2413
the Document does not specify a version number of this License,
2414
you may choose any version ever published (not as a draft) by the
2415
Free Software Foundation.
2417
ADDENDUM: How to use this License for your documents
2418
====================================================
2420
To use this License in a document you have written, include a copy of
2421
the License in the document and put the following copyright and license
2422
notices just after the title page:
2424
Copyright (C) YEAR YOUR NAME.
2425
Permission is granted to copy, distribute and/or modify this document
2426
under the terms of the GNU Free Documentation License, Version 1.2
2427
or any later version published by the Free Software Foundation;
2428
with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
2429
Texts. A copy of the license is included in the section entitled ``GNU
2430
Free Documentation License''.
2432
If you have Invariant Sections, Front-Cover Texts and Back-Cover
2433
Texts, replace the "with...Texts." line with this:
2435
with the Invariant Sections being LIST THEIR TITLES, with
2436
the Front-Cover Texts being LIST, and with the Back-Cover Texts
2439
If you have Invariant Sections without Cover Texts, or some other
2440
combination of the three, merge those two alternatives to suit the
2443
If your document contains nontrivial examples of program code, we
2444
recommend releasing these examples in parallel under your choice of
2445
free software license, such as the GNU General Public License, to
2446
permit their use in free software.
