- ;;; 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.
