# this script expects the following environment variables:

#	pb_init = the current status of the progress bar

#	pb_count = number of currently executed start/stop script

#	pb_scripts = number of scripts to be executed for runlevel change

#	pb_rate = the progress bar rate of the current boot process

#	RUNLEVEL = runlevel to be reached

#

# execute splash binary utility because we are a wrapper
