'''[http://www.gnu.org/%|%GNU]''', a [http://www.catb.org/jargon/html/R/recursive-acronym.html%|%recursive acronym] for '''[GNU]'s Not [Unix]''', project founded by [Richard Stallman] to promote free software. ** Attributes ** website: http://www.gnu.org/ ** Reading ** [http://www.gnu.org/gnu/initial-announcement.html%|%Initial Announcement] ,[Richard Stallman] ,1983-09-27: ** Description ** '''GNU''' refers to various closely related things, but they all stem from [Richard Stallman] and the [FSF]'s attempt to create a complete [UNIX] system that is completely free from commercial ties. Tcl programmers should take note of two particular aspects of the GNU project: '''[gcc]''': the GNU [C] Compiler, is by far and wide the most widely portable [C] compiler in the world, and it is (or should be) the aim of anyone developing the [Tcl] core (or common extensions) to compile completely cleanly using this compiler, even when all warnings are turned on. '''[GPL]''': The GNU Public License is a family of software licenses that are common among FSF developers and many others. '''gcc''' is called nowadays the GNU Compiler Collection, given the variety of front- and backends to the same internal engine. <> Category Glossary
