                     23: .I Halt
                     24: writes out sandbagged information to the disks and then stops
                     25: the processor.  The machine does not reboot, even if the auto-reboot
                     26: switch is set on the console.

                     29: .B \-n
                     30: option prevents the sync before stopping.  The
                     31: .B \-q
                     32: option causes a quick halt, no graceful shutdown is attempted.  The
                     33: .B \-y
                     34: option is needed if you are trying to halt the system from a dialup.
                     35: .PP
                     36: .I Halt
                     37: normally logs the shutdown using
                     38: .IR syslog (8)
                     39: and places a shutdown record in the login accounting file
                     40: /usr/adm/wtmp.
                     41: These actions are inhibited if the
                     42: .B \-n

                     48: .SH BUGS
                     49: It is very difficult to halt a VAX, as the machine wants to then
                     50: reboot itself.  A rather tight loop suffices.
