    # This script configures the ROS environment variables according to the route
    # to the ROS_MASTER. ROS_MASTER can either be defined as an evironment variable
    # itself or given as first argument to this script. The ROS_IP and ROS_HOSTNAME
    # are set according to the IP that is sitting on the route to this master.
    # The ROS_MASTER_URI is also set, using port 11311. ROS_MASTER needs to be defined
    # as a numeric IP address, not a hostname.
