+;;; 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.
