# ABOUT THIS PROGRAM
#
# NAME
#	enableFileSharing.sh -- Enables or Disables Personal File Sharing on Mac OS X Clients.
#
# SYNOPSIS
#	sudo enableFileSharing.sh
#	sudo enableFileSharing.sh <mountPoint> <computerName> <currentUsername> <enableFileSharing>
#
# 	If there is a hardcoded value specified for <enableFileSharing> in the script, 
#	or if the parameter is not passed by The Casper Suite, the hardcoded value in the script will 
#	be used.
#
#	The data that is specified for the <enableFileSharing> parameter should be specified in one of
#	the following formats:
#
#		"t" "T" "true" "True" "TRUE"
#		"f" "F" "false" "False" "FALSE"
#		"y" "Y" "yes" "Yes "YES"
#		"n" "N" "no" "No" "NO"
#
# DESCRIPTION
#	This script enables or disables the Personal File Sharing preference on Mac OS X 10.3 or later.
#	It can be used with a hardcoded value in the script, or read in as a parameter.
#	Since the Casper Suite defines the first three parameters as (1) Mount Point, (2) Computer
#	Name and (3) username, we are using the fourth parameter ($4) as the passable parameter to
#	acquire the status of <enableFileSharing>.  In addition, the fourth parameter is utilized to set 
#	the enableFileSharing parameter.
