;;; Commentary:
;;; AJR copied S+5 to be S+6.
;;; AJR copied S4 to be S+5.
;;; DB contributed the changes from essd-sp3.el to
;;; essd-s4.el. (removed the old ugly approach).
;;; This file defines Sp5 customizations for ess-mode.  Lots of thanks
;;; to RMH and JMC for code and suggestions
;;; Thanks to MM for making this sensible.

;;; Requires and Autoloads:

(require 'essl-s)

(autoload 'inferior-ess "ess-inf" "Run an ESS process.")
(autoload 'ess-mode     "ess-mode" "Edit an ESS process.")

;;; Code:

;; You now need to make sure you've defined if you are running 5.0 or 5.1.
;; Lots of things are broken between them, GRR...
