Overview
GNU Emacs is an extensible, customizable, self-documenting real-time display editor (High Caliber text editor). Basically, it has all the tools a programmer/Hacker could ever ask for.
Beyond editing, it is also a file manager, a news, mail, RSS feeds reader, and it plays games too. You could think of Emacs as a miniature operating system
