"""Tool for running suites of tests and waiting for completion.

The desired test suite will be scheduled with autotest, and then
this tool will block until the job is complete, printing a summary
at the end.  Error conditions result in exceptions.

This is intended for use only with Chrome OS test suits that leverage the
dynamic suite infrastructure in server/cros/dynamic_suite.py.
