-share and change all versions of a program--to make sure it remains free 
-software for all its users. We, the Free Software Foundation, use the 
-GNU General Public License for most of our software; it applies also to 
-any other work released this way by its authors. You can apply it to 
-your programs, too.
-
-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 
-them 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.
-
-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.
