qmail startup script

[frozenpeas]

When I am booting, I get an error to the effect of "unexpected error at line 14... stop..."

Is there anything wrong with my startup script (from the SAMS book, Running qmail):

#!/bin/sh

PATH=/var/qmail/bin
export PATH

#Check that qmail is loaded
[ -f /var/qmail/bin/qmail-start ] || exit 0

case "$1" in
  start)
        echo -n "Starting qmail..."
        daemon /var/qmail/rc

  stop)
        echo -n "Stopping qmail..."
        killall qmail-send

  restart)
        $0 stop
        $0 start

  *)
        echo -n "Usage: $0 {start|stop|restart}"
        exit 1
esac

exit 0
