 The extractClickConfig script produces router configurations for your experiment. It also creates a diagram of your experiment. Copy it back to the '''click-example''' directory on your local host so you can view it. There's a copy on each of your router hosts. I've chosen pc336.emulab.net, which is the top router, but it doesn't matter. You'll need to find the host name in the script output above, and then run this command ''on your local machine''.
