;; file.
;;
;; This file only contains the code needed to define new widget types.
;; Everything else is autoloaded from `wid-edit.el'.

;;; Code:

;; Doing this is unnecessary in Emacs 20.  Kept as dummy in case
;; external libraries call it.  We save a kb or two of purespace by
;; dummying-out such definitions generally.
