Free software is a matter of liberty, not price. To understand the concept, you should think of free as in free speech, not as in free beer

NOT gratis

from http://www.gnu.org

Free Software

The freedom to run the program, for any purpose (freedom 0).

The freedom to study how the program works, and adapt it to your needs (freedom 1). Access to the source code is a precondition for this.

The freedom to redistribute copies so you can help your neighbour (freedom 2).

The freedom to improve the program, and release your improvements to the public, so that the whole community benefits (freedom 3). Access to the source code is a precondition for this.

I am honored to follow Doctor Richard Stallman, the giant upon whose shoulders Open Source stands. When I say Open Source, I mean the same thing that Richard means when he says Free Software. There has been factionalism, but only because of personalities that no longer matter -- by Bruce
