+
+;;; Commentary:
+
+;; This file provides 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 Emacs
+;; with a minimum amount of hassles.
+
+;; Enable this package by putting the following in your .emacs
+;; (require 'crisp)
+
+;; 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.
+
+;; All these overrides should go *before* the (require 'crisp) statement.
+
+;; local variables
