# This script must be run as root and sets up Mac OS X to route all .kite domains to the virtual box VM with the name
# 'boot2docker-vm'. It does the following:
# 1) Adds a file under /etc/resolver/kite
# 2) Sets up a LaunchAgent for adding entries to the route table to route all requests to the Docker subnet (172.17.0.0/16)
# And expects the $IFNAME variable to contain the interface on which to send traffic to the boot2docker VM.
