+;; Definitions for the Mac Roman character sets and coding system.
+;; The Mac Roman encoding uses all 128 code points in the range 128 to
+;; 255 for actual characters.  Emacs decode them to one of the
+;; following character sets.
+;;	ascii, latin-iso8859-1, mule-unicode-0100-24ff,
+;;	mule-unicode-2500-33ff, mule-unicode-e000-ffff
