python testing with nose

sometimes i wonder if i should use a utility like nose. i guess if i ever start using unittest, i will. so far, though, i've found ways to do everything i want with doctest. maybe an autodiscovery tool would be helpful, even for doctest. it would be even better if the test framework handled dependencies intelligently. i thought about doing this with bicyclerepairman, but i couldn't do it in under an hour so i quit. one of these days... someone else will do it and i'll copy and paste.
