;;; Commentary:
-;; 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 defaults like a
-;; yellow background. Also, using PBM means we can display the images
-;; more generally. -- fx
-;; `smiley.el' was replaced by `smiley-ems.el' on 2002-01-26 (after fx'
-;; comment).
