+;;; Commentary:
+
+;; Keybindings and minor functions to duplicate the functionality and
+;; finger-feel of the Crisp/Brief editor.  This package is designed to
+;; facilitate transitioning from Brief to (XE|E)macs with a minimum
+;; amount of hassles.
+
+;; Enable this package by putting the following in your .emacs
+;; (require 'crisp)
+;; and use M-x crisp-mode to toggle it on or off.
+
+;; This package will automatically default to loading the scroll-lock.el
+;; package unless you put (setq crisp-load-scroll-lock nil) in your
+;; .emacs.  If this feature is enabled, it will bind meta-f1 to the
+;; scroll-lock mode toggle.
+
+;; Also, the default keybindings for brief override the meta-x key to
+;; exit the editor.  If you don't like this functionality, you can
+;; prevent this key from being rebound with
+;; (setq crisp-override-meta-x nil) in your .emacs.
+
+;; Finally, if you want to change the string displayed in the modeline
+;; when this mode is in effect, override the definition of
+;; `crisp-mode-modeline-string' in your .emacs.  The default value is
+;; " *Crisp*" which may be a bit lengthy if you have a lot of things
+;; being displayed there.
+
+;; All these overrides should go *before* the (require 'crisp) statement.
+
+;; local variables
