 #	This script is a test resource for introducing delay.

 #	usage: $0  {start|stop|status|monitor|meta-data}
 #
 #	  OCF parameters are as below:
 #		OCF_RESKEY_startdelay
 #		OCF_RESKEY_stopdelay
 #		OCF_RESKEY_mondelay
 #
 #	
 #		OCF_RESKEY_startdelay defaults to 20 (seconds)
 #		OCF_RESKEY_stopdelay defaults to $OCF_RESKEY_startdelay
 #		OCF_RESKEY_mondelay defaults to $OCF_RESKEY_startdelay
 #
 #
 #	This is really a test resource script.
