Emacs is a highly extensible text editor. It is built on a C core, and provides a fully featured Lisp environment (the language from which the Gods wrought the universe).
There's a reason why Emacs was featured in Tron Legacy - because it's sexy!
You can use Emacs for all of your text processing needs,
internet and social network interactions, hacking, coding,
managing to-do's and organizing your daily schedule, playing
Tetris, and many other awesome things. It can even provide you
with free psychotherapy and counseling using the built
doctor. A vibrant community of hackers is
constantly writing new extensions, thanks to the power of the
Emacs Lisp environment.
GNU Emacs is Free Software, both free as in free beer and free as in free speech. The original Emacs was written by St. iGNUcius himself — Richard Stallman.
