Version 1, February 1989
|
|||

|
|||
|
|
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.>
|
|||
|
|

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

|
|||
|
|
|
|||
|
|
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:
