-to ring the terminal's bell at the
-end of each page, while the
-.B \-clear
-option tells
-.B mhl
-to clear the
-screen at the end of each page (or output a formfeed after each message).
-Both of these switches (and their inverse counterparts) take effect only
-if the profile entry
-.I moreproc
-is defined but empty, and
-.B mhl
-is outputting to a terminal. If the
-.I moreproc
-entry is defined and
-non-empty, and
-.B mhl
-is outputting to a terminal, then
-.B mhl
-will
-cause the
-.I moreproc
-to be placed between the terminal and
-.B mhl
-and the switches are ignored. Furthermore, if the
-.B \-clear
-switch is
-used and \fImhl's\fR output is directed to a terminal, then
-.B mhl
-will consult the
-.B $TERM
-and
-.B $TERMCAP
-environment variables
-to determine the user's terminal type in order to find out how to clear
-the screen. If the
-.B \-clear
-switch is used and
-.BR mhl 's
-output is
-not directed to a terminal (e.g., a pipe or a file), then
-.B mhl
-will
-send a formfeed after each message.

-To override the default
