PROGRAM AS PERMITTED ABOVE, BE
LIABLE
TO YOU FOR DAMAGES, INCLUDING
A
NY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL
DAMAGES ARISING OUT OF
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 them 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 prevent
others
from denying you these rights or asking
you
to surrender the rights. Therefore, you have
certain
responsibilities if you distribute copies of
the
software, or if you modify it: responsibilities to
respect the freedom of others.
For example, if you distribute copies of such
a program, whether gratis or for a fee, you
must
pass on to the recipients the same freedoms that
you received. 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.
Developers that use the GNU GPL protect your
rights with two steps: (1) assert copyright on
the
software, and (2) offer you this License giving
you
legal permission to copy, distribute and/or modify it.

Preamble
The GNU General Public License is a free, copyleft
license for software and other kinds of works.
The licenses for most software and other practical
works are designed to take away your freedom to
share and change the works. By contrast, the GNU
General Public License is intended to guarantee
this
way by its authors. You can apply it to your
prog
rams, too.
(INCLUDING BUT NO
T 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
For the developers’ and authors’ protection, the
GPL clearly explains that there is no warranty
for
this free software. For both users’ and authors’
sake, the GPL requires that modified versions be
marked as changed, so that their problems will not
be attributed erroneously to authors of previous
versions.
Some devices are designed to deny users
access
to install or run modified versions of the
software
inside them, although the manufacturer can do
so.
This is fundamentally incompatible with the aim of
protecting users’ freedom to change
the
software. The systematic pattern of such
abuse
occurs in the area of products for individuals to use,
which is precisely where it is most unacceptable.
Therefore, we have designed this version of
the
GPL to prohibit the practice for those products. If
such problems arise substantially in other domains,
we stand ready to extend this provision to
those
domains in future versions of the GPL, as needed to
protect the freedom of users.
Finally, every program is threatened constantly
by software patents. States should not
allow
for
all its users. We, the Free Software Foundation,
use
the GNU General Public License for most of our
software;
it applies also to any other work released
your
freedom to share and change all versions of
a
program--to make sure it remains free software
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER
PA
RTY WHO MAY MODIFY AND/OR REDISTRIBUTE
patents to restrict development and use of software
on general-purpose computers, but in those that
do, we wish to avoid the special danger that
patents applied to a free program could make it
effectively proprietary. To prevent this, the
GPL
assures that patents cannot be used to render
the
program non-free.
The precise terms and conditions for
copying,
distribution and modifi cation follow.
