the works. By contrast, the GNU General Public License is
intended to guarantee your freedom to share and change
all versions of a program--to make sure it remains free
software 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 this way by its
authors. 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 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.
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
