 Preface
 *******
 
 Most of the GNU Emacs integrated environment is written in the
 programming language called Emacs Lisp.  The code written in this
 programming language is the software—the sets of instructions—that tell
 the computer what to do when you give it commands.  Emacs is designed so
 that you can write new code in Emacs Lisp and easily install it as an
 extension to the editor.
 
    (GNU Emacs is sometimes called an “extensible editor”, but it does
 much more than provide editing capabilities.  It is better to refer to
 Emacs as an “extensible computing environment”.  However, that phrase is
 quite a mouthful.  It is easier to refer to Emacs simply as an editor.
 Moreover, everything you do in Emacs—find the Mayan date and phases of
 the moon, simplify polynomials, debug code, manage files, read letters,
 write books—all these activities are kinds of editing in the most
 general sense of the word.)
