  9. Most of the GNU Emacs text editor is written in the programming language
  10. called Emacs Lisp. You can write new code in Emacs Lisp and install it as an
  11. extension to the editor. However, Emacs Lisp is more than a mere "extension
  12. language"; it is a full computer programming language in its own right. You
  13. can use it as you would any other programming language.
  14. Because Emacs Lisp is designed for use in an editor, it has special features
  15. for scanning and parsing text as well as features for handling files,
  16. buffers, displays, subprocesses, and so on. Emacs Lisp is closely integrated
  17. with the editing facilities; thus, editing commands are functions that can
  18. also conveniently be called from Lisp programs, and parameters for
  19. customization are ordinary Lisp variables.
  20. This manual attempts to be a full description of Emacs Lisp. For a
  21. beginner's introduction to Emacs Lisp, see An Introduction to Emacs Lisp
  22. Programming, by Bob Chassell, also published by the Free Software
  23. Foundation. This manual presumes considerable familiarity with the use of
  24. Emacs for editing; see The GNU Emacs Manual for this basic information.
