This file is the compressed file of the run level script

# Description : Gnu Makefile to control the services in the specified
#               runlevel. It will run the required services, and log
#               the output of the services to the file
#               /var/log/initd.start (for service startup) and
#               /var/log/initd.stop (for service shutdown).
#
#               This controlling program is designed to be invoked by
#               the "/etc/rc.d/rc" script.
#
# Author      : [e-mail]
#
# Notes       :
#
# - Run as,
#
#    make [-n] -j -f runlevel.mk \
#        RUNLEVEL={0|1|2|3|4|5|6} \
#        JOB={start|stop|restart|status}
#
# - $(JOB) is not validated - that is left to the service program.
# - $(RUNLEVEL) is not validated - that is left to the calling program
#   (usually /etc/rc.d/rc).
# - It wouldn't take too much effort to auto-generate this Makefile.
