  16   Most of the GNU Emacs text editor is written in the programming
  17 language called Emacs Lisp.  You can write new code in Emacs Lisp and
  18 install it as an extension to the editor.  However, Emacs Lisp is more
  19 than a mere ``extension language''; it is a full computer programming
  20 language in its own right.  You can use it as you would any other
  21 programming language.
  22
  23   Because Emacs Lisp is designed for use in an editor, it has special
  24 features for scanning and parsing text as well as features for handling
  25 files, buffers, displays, subprocesses, and so on.  Emacs Lisp is
  26 closely integrated with the editing facilities; thus, editing commands
  27 are functions that can also conveniently be called from Lisp programs,
  28 and parameters for customization are ordinary Lisp variables.

  30   This manual describes Emacs Lisp.  Generally speaking, the earlier
  31 chapters describe features of Emacs Lisp that have counterparts in
  32 many programming languages, and later chapters describe features that
  33 are peculiar to Emacs Lisp or relate specifically to editing.
