+# Emulation of compiled mhmail(1) using nmh send(1) or post(8).
+# Differences from compiled mhmail:
+# * Supports all send(1) (with -profile) or post(8) (without -profile) options.
+# * Optionally (with -profile) obeys the users profile, including
+#   AliasFile and send entries.
+# * Adds -debug option for debugging (sending, not incorporating new mail).
+#
+# To do:
+# * update mhmail man page
+# * add mhmail test
+# * integrate into autoconf
+# * support undocumented mhmail options?
