-
-The `\-prompt string' switch sets the prompting string for \fImsh\fR.
-
-You may wish to use an alternate \fInmh\fR profile for the commands that
-\fImsh\fR executes; see \fImh-profile\fR\0(5) for details about the
-\fB$MH\fR environment variable.
-
-When invoked from \fIbbc\fR, two special features are enabled:
-First, the `\-scan' switch directs \fImsh\fR to do a `scan\0unseen'
-on start\-up if new items are present in the BBoard. This feature is
-best used from \fIbbc\fR, which correctly sets the stage. Second, the
-\fImark\fR command in \fImsh\fR acts specially when you are reading a
-BBoard, since \fImsh\fR will consult the sequence \*(lqunseen\*(rq in
-determining what messages you have actually read. When \fImsh\fR exits,
-it reports this information to \fIbbc\fR. In addition, if you give the
-\fImark\fR command with no arguments, \fImsh\fR will interpret it as
-`mark\0\-sequence\0unseen\0\-delete\0\-nozero\0all' Hence, to discard
-all of the messages in the current BBoard you're reading, just use the
-\fImark\fR command with no arguments.
-
-Normally, the \*(lqexit\*(rq command is identical to the \*(lqquit\*(rq
-command in \fImsh\fR. When run under \fIbbc\fR however, \*(lqexit\*(rq
-directs \fImsh\fR to mark all messages as seen and then \*(lqquit\*(rq.
-For speedy type\-in, this command is often abbreviated as just
-\*(lqe\*(rq.
-
-When invoked from \fIvmh\fR, another special feature is enabled:
-The `topcur' switch directs \fImsh\fR to have the current message
-\*(lqtrack\*(rq the top line of the \fIvmh\fR scan window. Normally,
-\fImsh\fR has the current message \*(lqtrack\*(rq the center of the window
-(under `\-notopcur', which is the default).
-
-\fImsh\fR supports an output redirection facility. Commands may be
