Page "Emacs Lisp" Paragraph 4

Other methods exist for customizing GNU Emacs apart from writing Emacs Lisp.

Since version 20, GNU Emacs has included a " Customize " facility which allows users to set common customization variables through a graphical interface.

" Customize " works by writing Emacs Lisp code for the user, and is limited to relatively simple customizations.

Not every user needs the full degree of extensibility offered by Emacs ; those who do can write their own Emacs Lisp code.
