#Mac OSX Wi-Fi Location Changer

• Automatically changes the Mac OSX network location when Wi-Fi connection SSID changes
• Allows having different IP settings depending on the Wi-Fi SSID

Based on http://tech.inhelsinki.nl/locationchanger/
Forked from https://github.com/rimar/wifi-location-changer/

##Configuration

Edit locationchanger and change/add locations to be set:

# LOCATIONS
Location_McGill="wpa.mcgill.ca"
Location_EduRoam="wpa.mcgill.ca"

# SSIDS
SSID_McGill=wpa.mcgill.ca

Edit/Add SSID -> LOCATION mapping to list:

# SSID -> LOCATION mapping
case $SSID in
	$SSID_McGill ) LOCATION="$Location_McGill";;
	$SSID_Home          ) LOCATION="$Location_Home";;
	$SSID_EduRoam  ) LOCATION="$Location_EduRoam";;
	# ... add more here
