        !            37: .I Halt
        !            38: writes out sandbagged information to the disks and then stops
        !            39: the processor.  The machine does not reboot, even if the auto-reboot
        !            40: switch is set on the console.
        !            41: .PP
        !            42: The
        !            43: .B \-n
        !            44: option prevents the sync before stopping.  The
        !            45: .B \-q
        !            46: option causes a quick halt, no graceful shutdown is attempted.  The
        !            47: .B \-y
        !            48: option is needed if you are trying to halt the system from a dialup.
        !            49: .PP
        !            50: .I Halt
        !            51: normally logs the shutdown using
        !            52: .IR syslog (8)
        !            53: and places a shutdown record in the login accounting file
        !            54: /var/log/wtmp.
        !            55: These actions are inhibited if the
        !            56: .B \-n
        !            57: or
        !            58: .B \-q
        !            59: options are present.

        !            61: reboot(8), shutdown(8), syslogd(8)
        !            62: .SH BUGS
        !            63: It is very difficult to halt a VAX, as the machine wants to then
        !            64: reboot itself.  A rather tight loop suffices.
