GNU GENERAL PUBLIC
LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 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 licenses for most software are designed to take away
your freedom to share and change it. By contrast, the
GNU 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. This General
Public License applies to most of the Free Software
Foundation’s software and to any other program whose
authors commit to using it. (Some other Free Software
Foundation software is covered by the GNU Library
General Public License instead.) You can apply it to your
programs, too.
When we speak of free software, we are referring to
freedom, not price. Our General Public Licenses are
designed to make sure that you have the freedom to
distribute copies of free software (and charge for this
service if you wish), 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 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
show them these terms so they know 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.
Finally, any free program is threatened constantly by
software patents. We wish to avoid the danger that
redistributors of a free program will individually obtain
patent licenses, in effect making the program proprietary.
To prevent this, we have made it clear that any patent
must be licensed for everyone’s free use or not licensed
at all.
The precise terms and conditions for copying, distribution
and modification follow.
TERMS AND CONDITIONS FOR COPYING,
DISTRIBUTION AND MODIFICATION
0. This License 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
derivative work under copyright law: that is to say, a
work containing the Program or a portion of it, either
verbatim or with modifications and/or translated into
another language. (Hereinafter, translation is included
without limitation in the term “modification”.) Each
licensee is addressed as “you”.
Activities other than copying, distribution and
modification are not covered by this License; they are
outside its scope. The act of running the Program is not
restricted, and the output from the Program is covered
only if its contents constitute a work based on the
Program (independent of having been made by running
the Program). Whether that is true depends on what the
Program does.
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 License and
to the absence of any warranty; and give any other
recipients of the Program a copy of this License along
with the Program.
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.
2. You may modify your copy or copies of the Program
or any portion of it, thus forming a work based on the
Program, and copy and distribute such modifications
or work under the terms of Section 1 above, provided
that you also meet all of these conditions:
a) You must cause the modified files to carry
prominent notices stating that you changed the
files and the date of any change.
b) You must cause any work that you distribute or
publish, that in whole or in part contains or is
derived from the Program or any part thereof,
to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads
commands interactively when run, you must cause
it, when started running for such interactive use
in the most ordinary 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 License. (Exception: if the Program itself
is interactive but does not normally print such an
announcement, your work based on the Program
is not required to print an announcement.)
