- <p> 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.
- </p>
- <p> We protect your rights with two steps: (1) copyright the software, and
- (2) offer you this license which gives you legal permission to copy,
- distribute and/or modify the software.
- </p>
- <p> 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>
- <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.
- </p>
- <p> The precise terms and conditions for copying, distribution and
- modification follow.
- </p>
