18    <p>
19    The free software definition presents the criteria for whether a
20    particular software program qualifies as free software.  From time to
21    time we revise this definition, to clarify it or to resolve questions
22    about subtle issues.  See the <a href="#History">History section</a>
23    below for a list of changes that affect the definition of free
24    software.

29  We maintain this free software definition to show clearly what must be  &ldquo;Free software&rdquo; means software that respects users'
30  true about a particular software program for it to be considered free  freedom and community.  Roughly, it means that <b>the users have the

34    &ldquo;free&rdquo; as in &ldquo;free speech,&rdquo; not as in
35    &ldquo;free beer&rdquo;.  We sometimes call it &ldquo;libre
36    software,&rdquo; borrowing the French or Spanish word for
37    &ldquo;free&rdquo; as in freedom, to show we do not mean the software
38    is gratis.
39  </p>  </p>
40    
41  <p>  <p>
42  &ldquo;Free software&rdquo; is a matter of liberty, not price.  To understand  We campaign for these freedoms because everyone deserves them.  With
43  the concept, you should think of &ldquo;free&rdquo; as in &ldquo;free speech,&rdquo;  these freedoms, the users (both individually and collectively) control
44  not as in &ldquo;free beer.&rdquo;  the program and what it does for them.  When users don't control the
45    program, we call it a &ldquo;nonfree&rdquo; or
46    &ldquo;proprietary&rdquo; program.  The nonfree program controls the
47    users, and the developer controls the program; this makes the
48    program <a href="/philosophy/free-software-even-more-important.html">
49    an instrument of unjust power</a>.

54  study, change and improve the software.  More precisely, it means that the  four essential freedoms:

74  <p>  <p>
75  A program is free software if users have all of these freedoms.  Thus,  A program is free software if it gives users adequately all of these
76  you should be free to redistribute copies, either with or without  freedoms.  Otherwise, it is nonfree.  While we can distinguish various
77  modifications, either gratis or charging a fee for distribution, to  nonfree distribution schemes in terms of how far they fall short of
78    being free, we consider them all equally unethical.</p>
79    
80    <p>In any given scenario, these freedoms must apply to whatever code
81    we plan to make use of, or lead others to make use of.  For instance,
82    consider a program A which automatically launches a program B to
83    handle some cases.  If we plan to distribute A as it stands, that
84    implies users will need B, so we need to judge whether both A and B
85    are free.  However, if we plan to modify A so that it doesn't use B,
86    only A needs to be free; B is not pertinent to that plan.</p>

88    <p>The rest of this page clarifies certain points about what makes
89    specific freedoms adequate or not.</p>
90    
91    <p>Freedom to distribute (freedoms 2 and 3) means you are free to

118    The freedom to run the program as you wish means that you are not

262    </p>
263    
264    <p>
265    Merely mentioning the existence of export regulations, without making
266    them a condition of the license itself, is acceptable since it does
267    not restrict users.  If an export regulation is actually trivial for
268    free software, then requiring it as a condition is not an actual
269    problem; however, it is a potential problem, since a later change in
270    export law could make the requirement nontrivial and thus render the
271    software nonfree.
272    </p>
273    
274    <p>
275    A free license may not require compliance with the license of a
276    nonfree program.  Thus, for instance, if a license requires you to
277    comply with the licenses of &ldquo;all the programs you use&rdquo;, in
278    the case of a user that runs nonfree programs this would require
279    compliance with the licenses of those nonfree programs; that makes the
