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