I may have worded this poorly, but I think you have to use the gui to add
new directories or tests, or specific tests. Otherwise, it does not know
what to do with those files. I get lots of warnings/errors from QMTest
when it comes across a tests thats not in the database (says something
like "could not load test".

This could be how we have written our python files.. but right now if you
run a tool and it generates some output.. where that output is placed is
not controlled. So it makes it difficult to clean up this intermediate
output.

Thanks for your feedback!!!
