6. OPEN-SOURCE SOFTWARE (OSS)
is computer software with its source
code made available with a license in
which the copyright holder provides
the rights to study, change, and
distribute the software to anyone and
for any purpose.

7. FOUR FREEDOMS
• Freedom #0
Use the software for any purpose
• Freedom #1
Study how the program works, and change it so it does your
computing as you wish
• Freedom #2
Redistribute copies so you can help your neighbour
• Freedom #3
Distribute copies of your modified versions to others. By doing
this you can give the whole community a chance to benefit from
your changes.
