+;;; Commentary:
+
+;; This library decodes MIME encodings such as base64 and
+;; quoted-printable to allow for better spam analysis.
+;;
+;; `spam-wash' should be called in a buffer containing the message.
+
+;;; Code:
+
+(require 'gnus-art)
+
+(defun spam-wash ()
+ "Treat the current buffer prior to spam analysis."
+ (interactive)
+ (run-hooks 'gnus-article-decode-hook)
+ (save-excursion
