 Why Study Emacs Lisp?
 =====================
 
 Although Emacs Lisp is usually thought of in association only with
 Emacs, it is a full computer programming language.  You can use Emacs
 Lisp as you would any other programming language.
 
    Perhaps you want to understand programming; perhaps you want to
 extend Emacs; or perhaps you want to become a programmer.  This
 introduction to Emacs Lisp is designed to get you started: to guide you
 in learning the fundamentals of programming, and more importantly, to
 show you how you can teach yourself to go further.
