Emacs is not an editor. Emacs is a way of thinking about the world, and
as such is a way of thinking about editors. The process of editing is Emacs,
but Emacs is more than the process of editing. When you ask what Emacs does,
you are asking a question with no answer, because Emacs doesn't do, it is
done to. Emacs just is. ... I hope this makes things clearer.
