;;; factor.el --- Interacting with Factor within emacs

;; Keywords: languages
;;; Commentary:
;;; Quick setup:

;; Add these lines to your .emacs file:
;;
;; (load-file "/scratch/repos/Factor/misc/factor.el")
;; (setq factor-binary "/scratch/repos/Factor/factor")
;; (setq factor-image "/scratch/repos/Factor/factor.image")
;;
;; Of course, you'll have to edit the directory paths for your system
;; accordingly.
;; accordingly. Alternatively, put this file in your load-path and use
;;
;; (require 'factor)
;;
;; instead of load-file.
;;
;; That's all you have to do to "install" factor.el on your
;; system. Whenever you edit a factor file, Emacs will know to switch
;; to Factor mode.
