GDB GENERAL PUBLIC LICENSE
(Clarified 20 March 1987)
Copyright (C) 1986 Richard M. Stallman
Everyone is permitted to copy and distribute verbatim copies
of this license, but changing it is not allowed.
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 GDB. 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 GDB, that you receive source code or else can get it
if you want it, that you can change GDB 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 GDB, 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 GDB. If GDB 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 Foundation,
Inc.) make the following terms which say what you must do to be
allowed to distribute or change GDB.
COPYING POLICIES
1. You may copy and distribute verbatim copies of GDB 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) 1986 Free Software Foundation, Inc." (or with the year updated if
that 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 GDB 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 GDB 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 GDB 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 third parties, at your option).
c) if the modified program serves as a debugger, cause it
when started running in the simplest and usual way, to print
an announcement including a valid copyright notice
"Copyright (C) 1986 Free Software Foundation, Inc." (or with
the year updated if 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.
3. You may copy and distribute GDB or any portion of it in
compiled, executable or object code form under the terms of Paragraphs
1 and 2 above provided that you do the following:
a) cause each such copy to be accompanied by the
corresponding machine-readable source code, which must
be distributed under the terms of Paragraphs 1 and 2 above; or,
b) cause each such copy to be accompanied by a
written offer, with no time limit, to give any third party
free (except for a nominal shipping charge) a machine readable
copy of the corresponding source code, to be distributed
under the terms of Paragraphs 1 and 2 above; or,
c) in the case of a recipient of GDB in compiled, executable
or object code form (without the corresponding source code) you
shall cause copies you distribute to be accompanied by a copy
of the written offer of source code which you received along
with the copy you received.
4. You may not copy, sublicense, distribute or transfer GDB
except as expressly provided under this License Agreement. Any attempt
otherwise to copy, sublicense, distribute or transfer GDB is void and
your rights to use the program 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 GDB into other free
programs whose distribution conditions are different, write to the Free
Software Foundation at 675 Mass Ave, Cambridge, MA 02139. 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.
In other words, go ahead and share GDB, but don't try to stop
anyone else from sharing it farther. Help stamp out software hoarding!
NO WARRANTY
BECAUSE GDB 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 GDB "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 GDB IS WITH YOU. SHOULD GDB PROVE DEFECTIVE, YOU
ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW WILL RICHARD M.
STALLMAN, THE FREE SOFTWARE FOUNDATION, INC., AND/OR ANY OTHER PARTY
WHO MAY MODIFY AND REDISTRIBUTE GDB 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 ANY OTHER PROGRAMS) GDB, EVEN
IF YOU HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, OR FOR
ANY CLAIM BY ANY OTHER PARTY.
