+;; A re-written, simplified version of Wes Hardaker's XEmacs smiley.el
+;; which might be merged back to smiley.el if we get an assignment for
+;; that.  We don't have assignments for the images smiley.el uses, but
+;; I'm not sure we need that degree of rococoness and they shouldn't
+;; have a yellow background by default.  Also, using XBM means we can
+;; display the images more generally.  -- fx
