-;;; Commentary:
-
-;; This code provides functions to list and edit the values of all global
-;; option variables known to loaded Emacs Lisp code.  There are two entry
-;; points, `list-options' and `edit' options'.  The latter enters a major
-;; mode specifically for editing option values.  Do `M-x describe-mode' in
-;; that context for more details.
-
-;; The customization buffer feature is intended to make this obsolete.
