 ``Free software'' is a matter of liberty, not price. To understand the concept, you should think of ``free'' as in ``free speech,'' not as in ``free beer.''  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, for the users of the software:  The freedom to run the program, for any purpose (freedom 0).  The freedom to study how the program works, and adapt it to your needs (freedom 1). Access to the source code is a precondition for this.  The freedom to redistribute copies so you can help your neighbor (freedom 2).  The freedom to improve the program, and release your improvements to the public, so that the whole community benefits (freedom 3). Access to the source code is a precondition for this. What is free/open software rusnakm.truni.sk
