"""Small integration test for registration client

This client can work either with the fake_device_server or a live server.
To use locally (with the fake device server), start the server in the
background (e.g. ../server.py) and run the program without arguments.

Otherwise, if you want to run against a live server, you must provide an
auth code. To get an auth code, run this script with the argument URL
which will print out a link for you to visit and get your auth code.

Then re-run the test with that auth code like so:

./client_lib_test <YOUR_AUTH_CODE>.
