# 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, -headerfield, and -attach options.
+# * Adds optional -to switch for recipient addresses.
# * 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 -debug option for debugging (sending, not incorporating new mail).
+# * 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:
-# * fix -resent with -profile
-# * rename -debug to -nosend and add -send (and note in doc that last one takes)
-# * add -attach file ... switch
