;;; example-config.el -- Example Rational Emacs user customization file -*- lexical-binding: t; -*-

;;; Commentary:
;;
;; Rational Emacs supports user customization through a `config.el' file
;; similar to this one.  You can copy this file as `config.el' to your
;; Rational Emacs configuration directory as an example.
;;
;; In your configuration you can set any Emacs configuration variable, face
;; attributes, themes, etc as you normally would.
;;
;; See the README.org file in this repository for additional information.
