# NAME
#	setWebProxy.sh -- Configure a web proxy for a specified network interface
#
# SYNOPSIS
#	sudo setWebProxy.sh
#	sudo setWebProxy.sh <mountPoint> <computerName> <currentUsername> <networkInterface>
#							<proxyAddress> <port> 
#
# 	If the $networkInterface parameter is specified (parameter 4), this is the Netowrk Interface for
#	which the search domains will be set.  The expected values for the $networkInterface parameter can
#	be found by running the command:
#
#		networksetup -listallnetworkservices
#
#	If the $proxyAddress parameter is specified (parameter 5), this is the proxy address that will
#	be set.
#
#	If the $port parameter is specified (parameter 6), this is the port to which the proxy traffic
#	be passed.
#
# 	If no parameters are specified for parameters 4, 5 or 6, the hardcoded value in the script will be
