;;; Commentary:
;;
;; This file provides a major mode for editing .ratpoisonrc files, and
;; functions to access ratpoison from within Emacs.

;;; History:
;; Version 0.2:
;;  - Added command-interpreter (from Shawn and Jay)
;;  - Added info-lookup functions (from Jay)
;;  - renamed to ratpoison.el
;;  - far better font-locking
;; Version 0.1:
;;  - initial version

;;; Todo:
;; - auto-completion of commands
;; - probably a bunch of other things
