Free of restrictions...
Hmm... free software? Just a moment to clarify what that means. Various sites talk about software which is "Free as in Beer" and "Free as in Speech" which is not how I prefer to explain it. To clarify...Software can be free of cost (Beer in the above example), the simplest example being freeware (you can have it without paying but you are not free to do as you please with it).
or
Software can be free of
restriction (Speech
in the above example, do practically everything but claim it as your
own or incorporate it into non-free software). These freedoms are that you can...
- Run the program, for any purpose.
- Study how the program works, and adapt it to your needs.
- Redistribute copies.
- Improve the program, and release your improvements to the public.
