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.
Your comments and suggestions about our licensing policies and our
software are welcome! Please contact the Free Software Foundation, Inc.,
675 Mass Ave, Cambridge, MA 02139, or call (617) 876-3296.
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.
