+
+Mail may be fetched from IMAP or POP3 servers, from local maildirs, or read
+from standard input.  It is then filtered based on regular expressions, its
+size or age, or the output of a (shell) command.  It can be rewritten by an
+external process, dropped, left on the server or delivered into maildirs,
+mboxes, to a file or pipe, or any combination.
+
+fdm is primarily designed for use by a single user, but can use privilege
+separation to safely deliver mail in multi-user setups.")
