  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. Because Emacs Lisp is designed for use in an editor, it has special
  23. features for scanning and parsing text as well as features for handling
  24. files, buffers, displays, subprocesses, and so on. Emacs Lisp is
  25. closely integrated with the editing facilities; thus, editing commands
  26. are functions that can also conveniently be called from Lisp programs,
  27. and parameters for customization are ordinary Lisp variables.
  28. This manual describes Emacs Lisp. Generally speaking, the earlier
  29. chapters describe features of Emacs Lisp that have counterparts in
  30. many programming languages, and later chapters describe features that
  31. are peculiar to Emacs Lisp or relate specifically to editing.
