 ;;; Commentary:
 
+;; Provides configuration of MIME media types from directly from Lisp
+;; and via the usual mailcap mechanism (RFC 1524).  Deals with
+;; mime.types similarly.
+
 ;;; Code:
 
+(eval-when-compile (require 'cl))
+(autoload 'mail-header-parse-content-type "mail-parse")
+
+;; `mm-delete-duplicates' is an alias for `delete-dups' in Emacs 22.
+(defalias 'mailcap-delete-duplicates
+  (if (fboundp 'delete-dups)
+      'delete-dups
