+The
+.B \-build
+switch is intended to be used by the Emacs mh-e interface
+to
+.BR nmh ,
+and is only present if
+.B nmh
+was compiled with support
+for mh-e. It implies
+.BR \-nowhatnowproc .
+It causes a file
+.I <mh\-dir>/reply
+to be created, containing the draft message that would normally be presented
+to the user for editing.
+No mail is actually sent. Note that this switch is not guaranteed to
+be present or to have the same effects in future versions of
+.BR nmh :
+it is documented here only for completeness.
+.PP
+The
+.B \-file
+.I msgfile
+switch specifies the message to be replied to as an
+exact filename rather than as an
+.B nmh
+folder and message number. It is
+intended to be used by the
+.B msh
+interface to
+.BR nmh .
+The same caveats apply to this option as to the
+.B \-build
+switch.
