Open and edit test/testgooglereader.py and edit the cfg dict in the setUp method of the testcase. Use a test google reader username and password and a client id so Google can identify the client. Then run nosetests -v test/testgooglereader.py to run the tests. This is a bit rubbish but I don't know of nice way to pass arguments to nose.
View usage.py to see examples on how to use the client or run it to see GR's output.
- Update to use the latest version of restkit (1.3.0+). Will then be able to remove the json stuff and support Google's oAuth.
