What is Free Software?
- GNU Project - Free Software Foundation
Since 1983, developing the free Unix style operating system GNU, so that computer users can have the freedom to share and improve the software they use.
www.gnu.org
A program is free software if its users have the four essential freedoms: Freedom to...
* run the program for any purpose (freedom 0);
* study, and change, the program (freedom 1);
* redistribute copies to help others (freedom 2); and,
* distribute modified copies (freedom 3).
