README has outdated instructions for running the test suite
On current Git master, the documented instructions to run the test suite fail with:
$ python test.py [...] Please specify either --local or --system
Please make test.py's --local the default (I think it would be better for backward compatibility), or document that one must pass @--local@ or @--system@ in README.
