;;; Commentary:
;; writeroom-mode is a minor mode for Emacs that implements a
;; distraction-free writing mode similar to the famous Writeroom editor for
;; OS X. writeroom-mode is meant for GNU Emacs 24 and isn't tested on older
;; versions.
;;
;; See the README or info manual for usage instructions.
