Spend a few evenings with this free web book and experience what many computer scientists consider the best all-around programming language.

This manual attempts to be a full description of Emacs Lisp. Emacs Lisp is more than a mere 'extension language'; it is a full computer programming language in its own right. You can use it as you would any other programming language.
