back to when Richard Stallman had no gray hairs or wrinkles. Back to the time when RMS and the fine folks at the GNU project were writing compilers, debuggers, fileutils, shellutils, binutils, coreutils, diffutils, findutils, fontutils, Emacs, the Bash shell, and all the high-quality Linux tools that we take for granted, and that are the envy of Unix admins everywhere. Let us not forget the GPL, the General Public License, which ensured that all of that great code would be protected, freely available, and freely modifiable and re-distributable. That's a pretty neat trick.
