> 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.
|

</P

|
><P
|
|
> 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.
|
|
</P
|
|
><P
|
|
> 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.
|
|
</P
|
|
><P
|
|
> 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.

> 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.
|

</P

|
|
> 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.
