GNU GENERAL PUBLIC LICENSE
Version 1, February 1989
Copyright (C) 1989 Free Software Foundation, Inc. 51 Franklin St, Fifth Floor,
Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies of this license
document, but changing it is not allowed.
Preamble
The license agreements of most software companies try to keep users at the
mercy of those companies. By contrast, our General Public License is intended
to guarantee your freedom to share and change free software--to make sure
the software is free for all its users. The General Public License applies
to the Free Software Foundation's software and to any other program whose
authors commit to using it. You can use it for your programs, too.
When we speak of free software, we are referring to freedom, not price. Specifically,
the General Public License is designed to make sure that you have the freedom
to give away or sell copies of free software, that you receive source code
or can get it if you want it, that you can change the software or use pieces
of it in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to
deny you these rights or to ask you to surrender the rights. These restrictions
translate to certain responsibilities for you if you distribute copies of
the software, or if you modify it.
For example, if you distribute copies of a such a program, whether gratis
or for a fee, 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.
We protect your rights with two steps: (1) copyright the software, and (2)
offer you this license which gives you legal permission to copy, distribute
and/or modify the software.
Also, for each author's protection and ours, we want to make certain that
everyone understands that there is no warranty for this free software. If
the software is modified by someone else and passed on, we want its recipients
to know that what they have is not the original, so that any problems introduced
by others will not reflect on the original authors' reputations.
The precise terms and conditions for copying, distribution and modification
follow.
GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION
AND MODIFICATION
0. This License Agreement applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed under
the terms of this General Public License. The "Program", below, refers to
any such program or work, and a "work based on the Program" means either the
Program or any work containing the Program or a portion of it, either verbatim
or with modifications. Each licensee is addressed as "you".
1. You may copy and distribute verbatim copies of the Program's source code
as you receive it, in any medium, provided that you conspicuously and appropriately
publish on each copy an appropriate copyright notice and disclaimer of warranty;
keep intact all the notices that refer to this General Public License and
to the absence of any warranty; and give any other recipients of the Program
a copy of this General Public License along with the Program. You may charge
a fee for the physical act of transferring a copy.
2. You may modify your copy or copies of the Program 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 the Program or any part thereof, either with or without
modifications, to be licensed at no charge to all third parties under the
terms of this General Public License (except that you may choose to grant
warranty protection to some or all third parties, at your option).
c) If the modified program normally reads commands interactively when run,
you must cause it, when started running for such interactive use in the simplest
and most usual way, to print or display an announcement including an appropriate
copyright notice and a notice 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 General
Public License.
d) You may charge a 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 independent work with the Program (or its derivative)
on a volume of a storage or distribution medium does not bring the other work
under the scope of these terms.
3. You may copy and distribute the Program (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 charge for the cost of distribution)
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.)
Source code for a work means the preferred form of the work for making modifications
to it. 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, or for standard header files or
definitions files that accompany that operating system.
4. You may not copy, modify, sublicense, distribute or transfer the Program
except as expressly provided under this General Public License. Any attempt
otherwise to copy, modify, sublicense, distribute or transfer the Program
is void, and will automatically terminate your rights to use the Program under
this License. However, parties who have received copies, or rights to use
copies, from you under this General Public License will not have their licenses
terminated so long as such parties remain in full compliance.
5. By copying, distributing or modifying the Program (or any work based on
the Program) you indicate your acceptance of this license to do so, and all
its terms and conditions.
6. Each time you redistribute the Program (or any work based on the Program),
the recipient automatically receives a license from the original licensor
to copy, distribute or modify the Program subject to these terms and conditions.
You may not impose any further restrictions on the recipients' exercise of
the rights granted herein.
7. The Free Software Foundation may publish revised and/or new versions of
the General Public License from time to time. Such new versions will be similar
in spirit to the present version, but may differ in detail to address new
problems or concerns.
Each version is given a distinguishing version number. If the Program specifies
a version number of the license which applies to it and "any later version",
you have the option of following the terms and conditions either of that version
or of any later version published by the Free Software Foundation. If the
Program does not specify a version number of the license, you may choose any
version ever published by the Free Software Foundation.
8. If you wish to incorporate parts of the Program into other free programs
whose distribution conditions are different, write to the author to ask for
permission. For software which is copyrighted by the Free Software Foundation,
write to the Free Software Foundation; we sometimes make exceptions for this.
Our decision 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 generally.
NO WARRANTY
9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM
"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 PROGRAM PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES
OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH
HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible
use to humanity, the best way to achieve this is to make it free software
which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to attach
them to the start of each source file to most effectively convey the exclusion
of warranty; and each file should have at least the "copyright" line and a
pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.> Copyright
(C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify it under
the terms of the GNU General Public License as published by the Free Software
Foundation; either version 1, or (at your option) any later version.
This program is distributed in the hope that it will be useful, but WITHOUT
ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
You should have received a copy of the GNU General Public License along with
this program; if not, write to the Free Software Foundation, Inc., 675 Mass
Ave, Cambridge, MA 02139, USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this when
it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19xx name of author Gnomovision comes
with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software,
and you are welcome to redistribute it under certain conditions; type `show
c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may be
called something other than `show w' and `show c'; they could even be mouse-clicks
or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your school,
if any, to sign a "copyright disclaimer" for the program, if necessary. Here
a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision'
(a program to direct compilers to make passes at assemblers) written by James
Hacker.
