+In the node.js intro tutorial (http://nodejs.org/), they show a basic tcp
+server, but for some reason omit a client connecting to it.
+
+And connect with a tcp client from the command line using netcat, the *nix
+utility for reading and writing across tcp/udp network connections.  I've only
+used it for debugging myself.
+$ netcat 127.0.0.1 1337
