  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 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.
