'''This script runs all tests in a directory.
It does not need to know about the tests ahead of time.
It recursively descends from the current directory and
automatically builds up a list of tests to run.
Only directories named 'tests' are processed.
The path to each 'tests' directory is added to the PYTHONPATH.
Only python scripts that start with 'test_' are added to
the list of scripts in the test suite.
