GNU GENERAL PUBLIC LICENSE
Version 1, February 1989
Copyright © 1989 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307, 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 LICENSETERMS 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.
