;;; Emacs 20.x notes:

;; font-lock faces are defined in /emacs/emacs-20.5/lisp/font-lock.el
;; The font-lock faces are applied to ESS buffers by
;; ess-mode.el ess-inf.el ess-trns.el ess-cust.el
;; The keywords for faces are defined in the ess[dl]*.el files.
;; All faces can be looked at, under Emacs 20.x, with
;;        [menu-bar] [Edit] [Text Properties] [Display Faces}

;;; For XEmacs
