DESCRIPTION:
	This script transforms a stock Sample Depot instance into
	one that works with the SDP.

REQUIREMENTS:
	A P4D process must be live and running with the stock
	Sample Depot data set, on a sport 

ARGUMENTS:
 <sdp_instance>
	Specify the SDP Instance in which the Sample Depot data set is
	running.  This argument is required.

 -D     Set extreme debugging verbosity.

HELP OPTIONS:
 -h	Display short help message
 -man	Display man-style help message

EXAMPLES:
	Usage to configure Instance 1:
	cd /where/this/script/is
	$ThisScript 1 2>&1 | tee log.${ThisScript%.sh}.1

	Usage to configure Instance abc:
	cd /where/this/script/is
	$ThisScript abc 2>&1 | tee log.${ThisScript%.sh}.abc

# Functions.  The runCmd() function is similar to functions defined in SDP core
# libraries, but we need to duplicate them here since this script runs before
# the SDP is available on the machine (and we want no dependencies for this
# script.
