+;;; 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.
