GNU EMACS GENERAL PUBLIC LICENSE
|
||
|
(Clarified 11 Feb 1988)
|
||
|
|
||
|
Copyright (C) 1985, 1987, 1988 Richard M. Stallman
|
||
|
Everyone is permitted to copy and distribute verbatim copies
|
||
|
of this license, but changing it is not allowed. You can also
|
||
|
use this wording to make the terms for other programs.
|
||
|
|
||
|
The license agreements of most software companies keep you at the
|
||
|
mercy of those companies. By contrast, our general public license is
|
||
|
intended to give everyone the right to share GNU Emacs. To make
|
||
|
sure that you get the rights we want you to have, we need to make
|
||
|
restrictions that forbid anyone to deny you these rights or to ask you
|
||
|
to surrender the rights. Hence this license agreement.
|
||
|
|
||
|
Specifically, we want to make sure that you have the right to give
|
||
|
away copies of Emacs, that you receive source code or else can get it
|
||
|
if you want it, that you can change Emacs or use pieces of it in new
|
||
|
free programs, and that you know you can do these things.
|
||
|
|
||
|
To make sure that everyone has such rights, we have to forbid you to
|
||
|
deprive anyone else of these rights. For example, if you distribute
|
||
|
copies of Emacs, you must give the recipients all the rights that you
|
||
|
have. You must make sure that they, too, receive or can get the
|
||
|
source code. And you must tell them their rights.
|
||
|
|
||
|
Also, for our own protection, we must make certain that everyone
|
||
|
finds out that there is no warranty for GNU Emacs. If Emacs is
|
||
|
modified by someone else and passed on, we want its recipients to know
|
||
|
that what they have is not what we distributed, so that any problems
|
||
|
introduced by others will not reflect on our reputation.
|
||
|
|
||
|
Therefore we (Richard Stallman and the Free Software Fundation,
|
||
|
Inc.) make the following terms which say what you must do to be
|
||
|
allowed to distribute or change GNU Emacs.
|
||
|
|
||
|
COPYING POLICIES
|
||
|
|
||
|
1. You may copy and distribute verbatim copies of GNU Emacs source code
|
||
|
as you receive it, in any medium, provided that you conspicuously and
|
||
|
appropriately publish on each copy a valid copyright notice "Copyright
|
||
|
(C) 1988 Free Software Foundation, Inc." (or with whatever year is
|
||
|
appropriate); keep intact the notices on all files that refer to this
|
||
|
License Agreement and to the absence of any warranty; and give any
|
||
|
other recipients of the GNU Emacs program a copy of this License
|
||
|
Agreement along with the program. You may charge a distribution fee
|
||
|
for the physical act of transferring a copy.
|
||
|
|
||
|
2. You may modify your copy or copies of GNU Emacs source code or
|
||
|
any portion of it, and copy and distribute such modifications under
|
||
|
the terms of Paragraph 1 above, provided that you also do the following:
|
||
|
|
||
|
a) cause the modified files to carry prominent notices stating
|
||
|
that you changed the files and the date of any change; and
|
||
|
|
||
|
b) cause the whole of any work that you distribute or publish,
|
||
|
that in whole or in part contains or is a derivative of GNU Emacs
|
||
|
or any part thereof, to be licensed at no charge to all third
|
||
|
parties on terms identical to those contained in this License
|
||
|
Agreement (except that you may choose to grant more extensive
|
||
|
warranty protection to some or all third parties, at your option).
|
||
|
|
||
|
c) if the modified program serves as a text editor, cause it when
|
||
|
started running in the simplest and usual way, to print an
|
||
|
announcement including a valid copyright notice "Copyright (C)
|
||
|
1988 Free Software Foundation, Inc." (or with the year that is
|
||
|
appropriate), saying that there is no warranty (or else, saying
|
||
|
that you provide a warranty) and that users may redistribute the
|
||
|
program under these conditions, and telling the user how to view a
|
||
|
copy of this License Agreement.
|
||
|
|
||
|
d) You may charge a distribution fee for the physical act of
|
||
|
transferring a copy, and you may at your option offer warranty
|
||
|
protection in exchange for a fee.
|
||
|
|
||
|
Mere aggregation of another unrelated program with this program (or its
|
||
|
derivative) on a volume of a storage or distribution medium does not bring
|
||
|
the other program under the scope of these terms.
|
||
|
|
||
|
3. You may copy and distribute GNU Emacs (or a portion or derivative of it,
|
||
|
under Paragraph 2) in object code or executable form under the terms of
|
||
|
Paragraphs 1 and 2 above provided that you also do one of the following:
|
||
|
|
||
|
a) accompany it with the complete corresponding machine-readable
|
||
|
source code, which must be distributed under the terms of
|
||
|
Paragraphs 1 and 2 above; or,
|
||
|
|
||
|
b) accompany it with a written offer, valid for at least three
|
||
|
years, to give any third party free (except for a nominal
|
||
|
shipping charge) a complete machine-readable copy of the
|
||
|
corresponding source code, to be distributed under the terms of
|
||
|
Paragraphs 1 and 2 above; or,
|
||
|
|
||
|
c) accompany it with the information you received as to where the
|
||
|
corresponding source code may be obtained. (This alternative is
|
||
|
allowed only for noncommercial distribution and only if you
|
||
|
received the program in object code or executable form alone.)
|
||
|
|
||
|
For an executable file, complete source code means all the source code for
|
||
|
all modules it contains; but, as a special exception, it need not include
|
||
|
source code for modules which are standard libraries that accompany the
|
||
|
operating system on which the executable file runs.
|
||
|
|
||
|
4. You may not copy, sublicense, distribute or transfer GNU Emacs
|
||
|
except as expressly provided under this License Agreement. Any attempt
|
||
|
otherwise to copy, sublicense, distribute or transfer GNU Emacs is void and
|
||
|
your rights to use GNU Emacs under this License agreement shall be
|
||
|
automatically terminated. However, parties who have received computer
|
||
|
software programs from you with this License Agreement will not have
|
||
|
their licenses terminated so long as such parties remain in full compliance.
|
||
|
|
||
|
5. If you wish to incorporate parts of GNU Emacs into other free programs
|
||
|
whose distribution conditions are different, write to the Free Software
|
||
|
Foundation. We have not yet worked out a simple rule that can be stated
|
||
|
here, but we will often permit this. We will be guided by the two goals of
|
||
|
preserving the free status of all derivatives of our free software and of
|
||
|
promoting the sharing and reuse of software.
|
||
|
|
||

|
||
|
software are welcome! Please contact the Free Software Foundation, Inc.,

|
||
|
|
||
|
NO WARRANTY
|
||
|
|
||
|
BECAUSE GNU EMACS IS LICENSED FREE OF CHARGE, WE PROVIDE ABSOLUTELY
|
||
|
NO WARRANTY, TO THE EXTENT PERMITTED BY APPLICABLE STATE LAW. EXCEPT
|
||
|
WHEN OTHERWISE STATED IN WRITING, FREE SOFTWARE FOUNDATION, INC,
|
||
|
RICHARD M. STALLMAN AND/OR OTHER PARTIES PROVIDE GNU EMACS "AS IS"
|
||
|
WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
|
||
|
BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
|
||
|
FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY
|
||
|
AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE GNU EMACS
|
||
|
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
|
||
|
SERVICING, REPAIR OR CORRECTION.
|
||
|
|
||
|
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW WILL FREE SOFTWARE
|
||
|
FOUNDATION, INC., RICHARD M. STALLMAN, AND/OR ANY OTHER PARTY WHO MAY
|
||
|
MODIFY AND REDISTRIBUTE GNU EMACS AS PERMITTED ABOVE, BE LIABLE TO YOU
|
||
|
FOR DAMAGES, INCLUDING ANY LOST PROFITS, LOST MONIES, OR OTHER
|
||
|
SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
|
||
|
INABILITY TO USE (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA
|
||
|
BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY THIRD PARTIES OR A
|
||
|
FAILURE OF THE PROGRAM TO OPERATE WITH PROGRAMS NOT DISTRIBUTED BY
|
||
|
FREE SOFTWARE FOUNDATION, INC.) THE PROGRAM, EVEN IF YOU HAVE BEEN
|
||
|
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, OR FOR ANY CLAIM BY ANY
|
||
|
OTHER PARTY.
