 # Emulation of compiled mhmail(1), with these differences:
-# * Instead of silently not sending an empty message, notifies user
-#   "mhmail: empty message not sent, use -body '' to force."
-# * The compiled mhmail dropped a trailing newline from the -body argument.
+# * Adds -send/-nosend, -header-field, and -attach options.
 # * Supports all post(8) (by default, without -profile) or send(1)
 #   (with -profile) options.
 # * Optionally (with -profile) obeys the users profile, including
 #   AliasFile and send entries.
-# * Adds -nosend option, which displays the draft but does not send it.
+# * Instead of silently not sending an empty message, notifies user
+#   "mhmail: empty message not sent, use -body '' to force."
+# * The compiled mhmail dropped a trailing newline from the -body argument.
 # * Drops support for undocumented -queue option.
-#
-# To do:
-# * add -header-field name:body switch
-# * add -attach file ... switch
