this?
Hi Preston,
The PYTHONPATH in the PR snippet is about resolving
`DJANGO_SETTINGS_MODULE` by adding the path of the test project, not the
reusable app dev sources path (which is assumed). But maybe this is not
clear enough ?

Even with reusable apps it's nice to have the option of passing a path to
a test case, like `./runtests.py myapp.tests.SomeCase.test`. Should the
example take that into consideration?

Good point.
I wanted the snippet as simple as possible (how to convert a `manage.py
test` shell invocation into Python code). In that regard, I would replace
`sys.argv[1:] or ['myapp']` by `sys.argv[1:]` and update the runtests.py
invocation example with some optional arguments ''à la Django''
(`[path.to.modulename|path.to.modulename.TestCase|path.to.modulename.TestCase.test_method]`).
What do you think ?
