Starting a VPN if it is not connected via AppleScript

Launching a VPN if it is not connected on OS X:

tell application "System Events"
  tell current location of network preferences
    set VPNservice to service "My VPN" -- name of your VPN
    set isConnected to connected of current configuration of VPNservice
    if not isConnected then connect VPNservice
  end tell
end tell

…prefect for automating “things” in Proxi.
