#
# NAME
# enableFilewall.sh -- Enables or Disables the firewall on Mac OS X Clients.
#
# SYNOPSIS
# sudo enableFirewall.sh
# sudo enableFirewall.sh <mountPoint> <computerName> <currentUsername> <enableFirewall>
#
# If there is a hardcoded value specified for <enableFirewall> 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 <enableFirewall> parameter should be specified in one of
# the following formats:
#
# "TRUE"
# "FALSE"
# "YES"
# "NO"
#
# DESCRIPTION
# This script enables or disables the firewall 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 <enableFirewall>. In addition, the fourth parameter is utilized to set
# the enableFirewall parameter.
