# This script is intended to be placed in /etc/init.d/listproc 
# as well as /etc/rc3.d/K96listproc /etc/rc3.d/S96listproc
#
# Basically, it becomes the user "server" and starts the server process with
# the start command.  The start command stops existing ListProc processes 
# before starting itself again.
#
# There are three valid arguments you can send to this script:
#  start - starts ListProc and dispays a message to stndout
#  stop  - stops ListProc and dispays a message to stndout
#  version - prints the version of ListProc to stndout

# runpidfile - is a file which this script creates when starting listproc
#   and removes when stopping listproc.  You may choose to have another
