Free software is software which preserves the freedom of users to
modify and share software. We recognise the these four rights that
you, as a user of the software, must have:
- The freedom to run the program, for any purpose.
- The freedom to study how the program works, and adapt it to your needs.
- The freedom to redistribute copies so you can help your neighbor.
- The freedom to improve the program, and release your improvements to
the public, so that the whole community benefits.
