11 GNU GENERAL PUBLIC LICENSE
12 Version 3, 29 June 2007
13
14 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
15 Everyone is permitted to copy and distribute verbatim copies
16 of this license document, but changing it is not allowed.

18 Preamble
19
20 The GNU General Public License is a free, copyleft license for
21software and other kinds of works.
22
23 The licenses for most software and other practical works are designed
24to take away your freedom to share and change the works. By contrast,
25the GNU General Public License is intended to guarantee your freedom to
26share and change all versions of a program--to make sure it remains free
27software for all its users. We, the Free Software Foundation, use the
28GNU General Public License for most of our software; it applies also to
29any other work released this way by its authors. You can apply it to
30your programs, too.
31
32 When we speak of free software, we are referring to freedom, not
33price. Our General Public Licenses are designed to make sure that you
34have the freedom to distribute copies of free software (and charge for
35them if you wish), that you receive source code or can get it if you
36want it, that you can change the software or use pieces of it in new
37free programs, and that you know you can do these things.
38
39 To protect your rights, we need to prevent others from denying you
40these rights or asking you to surrender the rights. Therefore, you have
41certain responsibilities if you distribute copies of the software, or if
42you modify it: responsibilities to respect the freedom of others.
43
44 For example, if you distribute copies of such a program, whether
45gratis or for a fee, you must pass on to the recipients the same
46freedoms that you received. You must make sure that they, too, receive
47or can get the source code. And you must show them these terms so they
48know their rights.
49
50 Developers that use the GNU GPL protect your rights with two steps:
51(1) assert copyright on the software, and (2) offer you this License
52giving you legal permission to copy, distribute and/or modify it.
53
54 For the developers' and authors' protection, the GPL clearly explains
55that there is no warranty for this free software. For both users' and
56authors' sake, the GPL requires that modified versions be marked as
57changed, so that their problems will not be attributed erroneously to
58authors of previous versions.
59
60 Some devices are designed to deny users access to install or run
61modified versions of the software inside them, although the manufacturer
62can do so. This is fundamentally incompatible with the aim of
63protecting users' freedom to change the software. The systematic
64pattern of such abuse occurs in the area of products for individuals to
65use, which is precisely where it is most unacceptable. Therefore, we
66have designed this version of the GPL to prohibit the practice for those
67products. If such problems arise substantially in other domains, we
68stand ready to extend this provision to those domains in future versions
69of the GPL, as needed to protect the freedom of users.
70
71 Finally, every program is threatened constantly by software patents.
72States should not allow patents to restrict development and use of
73software on general-purpose computers, but in those that do, we wish to
