Frå Wikipedia – det frie oppslagsverket

(0) The freedom to run the program for any purpose; (1) The freedom to study how the program works and adapt it to your needs; (2) The freedom to redistribute copies so you can help your neighbor; (3) The freedom to improve the program and release your improvement to the public, so that the whole community benefits.

The first and third freedoms imply a final, and equally important, freedom: access to the source code of the program.
