1 We maintain this free software definition to show

clearly what must be true about a particular software program

for it to be considered free software: “free software” is a

4 matter of liberty, not price. To understand the concept, you

should think of “free” as in “free speech”, not as in “free

beer”.

7 Free software is a matter of the users’ freedom to

run, copy, distribute, study, change and improve the

software. More precisely, it refers to four kinds of freedom,

10 for the users of the software: 1) The freedom to run the

program, for any purpose; 2) The freedom to study how the

program works, and adapt it to your needs. Access to the

13 source code is a precondition for this; 3) The freedom to

redistribute copies so you can help your neighbor; 4) The

freedom to improve the program, and release your

16 improvements to the public, so that the whole community

benefits. Access to the source code is a precondition for this.

A program is free software if users have all of these

19 freedoms. Thus, you should be free to redistribute copies,

either with or without modifications, either gratis or charging

a fee for distribution, to anyone anywhere. Being free to do

22 these things means (among other things) that you do not have

to ask or pay for permission.

The freedom to use a program means the freedom

25 for any kind of person or organization to use it on any kind

of computer system, for any kind of overall job, and without

being required to communicate subsequently with the

28 developer or any other specific entity.

Internet: (with adaptations).

According to the text above, judge the following items.

Copies of a free software program may be redistributed for free or by selling them.
