# ABOUT THIS PROGRAM
#
# NAME
# 020 Turn Off Airport & Clear DNS
#
#
# DESCRIPTION
# Checks to see if Airport is an active service, if it's not it enables it. (this does not turn
# on the airport card, just stops the script from erroring).
#
# Clears all manual entries for DNS Servers & Search Domains if mac is 10.4 & if $4 is set to y.
# Clears DNS & Search Domains for 10.5 & up macs can receive dns from dhcp.
#
# Once all the above have been completed.. turns off Airport
