+;; Note: Metamail does not have all options which is compatible with
+;; the environment variables.  For that reason, matamail.el have to
+;; hack the environment variables.  In addition, there is no way to
+;; display all header fields without extra informative body messages
+;; which is suppressed by "-q" option.
+
+;; The idea of using metamail to process MIME messages is from
+;; gnus-mime.el by Spike <Spike@world.std.com>.
