GNU

GNU: /gnoo/, *not* /noo/  1. [acronym `GNU's Not
   UNIX!', see {{recursive acronym}}] A UNIX-workalike development
   effort of the Free Software Foundation headed by Richard Stallman
   <rms@gnu.ai.mit.edu>.  GNU EMACS and the GNU C compiler, two
   tools designed for this project, have become very popular in
   hackerdom and elsewhere.  The GNU project was designed partly to
   proselytize for RMS's position that information is community
   property and all software source should be shared.  One of its
   slogans is "Help stamp out software hoarding!"  Though this
   remains controversial (because it implicitly denies any right of
   designers to own, assign, and sell the results of their labors),
   many hackers who disagree with RMS have nevertheless cooperated to
   produce large amounts of high-quality software for free
   redistribution under the Free Software Foundation's imprimatur.

   founder of Usenet's anarchic alt.* hierarchy.
