Developers that use the GNU GPL protect your rights with two steps: (1) assert

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 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 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 modification follow.
