-;;; Test smileys: :-] :-o :-) ;-) :-\ :-| :-d :-P 8-| :-(
+;; 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
-;; To use:
-;; (require 'smiley)
-;; (add-hook 'gnus-article-display-hook 'gnus-smiley-display t)
+;;; Test smileys: :-) :-\ :-( :-/
-;; The smilies were drawn by Joe Reiss <jreiss@vt.edu>.
