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 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
