Emacs

Resources

Emacs denominates Article description::a class of powerful, extensible, self-documenting text editors. The original implementation is GNU Emacs, which is still updated today. There's also XEmacs, which was forked from GNU Emacs in the early 1990s. XEmacs is not the X version of Emacs, but a complete separate program.
