Z:gnu-www-ja-drdobbs-letter--90a2ab-Free software means, roughly,/en

Free software means, roughly, that you are free to study what it does, free to change it, free to redistribute it, and free to publish improved versions. (See http://www.gnu.org/philosophy/free-sw.html for more details.) You deserve these freedoms; everyone deserves them. I wrote the GNU General Public License (GNU GPL), the target of Microsoft's greatest ire, to defend these freedoms for all users, in the spirit of the free software movement.
