Trial has a command line tool for running suites, "trial".  If that code is
in eUnit/test/test_sample.py, then you can try any of these commands:

    trial eUnit
    trial eUnit.test
    trial eUnit.test.test_sample
    trial eUnit.test.test_sample.Test
    trial eUnit.test.test_sample.test.testSample
    trial /path/to/eUnit/
    trial /path/to/eUnit/test/
    trial /path/to/eUnit/test/test_sample.py

You don't need any of the code in your __main__ section.
