;;; Commentary:

;; Modified by Bob Weiner <weiner@infodock.com>, 1/13/94
;;   Handle XEmacs 19.8 pixmaps properly. 
;;   Also added in more mode settings and added many new bitmaps.
;;   Renamed from icon.el to frame-icon.el.
;;   Made all definitions start with the same prefix, 'icon-'.
;;   Added a provide clause.
;; Modified by Bob Weiner, 2/24/95, to handle XEmacs 19.12.
;;   Added set of unmap-frame-hook.
;; Modified by Bob Weiner, 7/17/95, to handle XEmacs 19.12.
;;   Changed to use new image-handling protocols and added backwards
;;   compatibility functions for new image functions.
;; Modified by Bob Weiner, 7/18/95.
;;   Added icon-suffix variable so can use .xbm or .xpm icons.
;; Most Icons were extracted from: /export.lcs.mit.edu:/contrib/AIcons

;;; Code:

(defvar icon-directory (locate-data-directory "frame-icon/")
  "Directory of icons used by frame-icon.el.")

(defvar icon-suffix ".xbm"
  "Must be .xbm or .xpm, depending on the format of the icons in icon-directory.")
