This is a bug in the distutils.log module, unfortunately. It only uses print.
Changing status to "feature" for 0.7a1, specifically to add & use a
setuptools.log.warn that writes warnings and errors to stderr.
Warning messages must be printed to stderr. This allows for a programattic way
to find setup.py metadata.

'dap.plugins' is declared as a package namespace, but 'dap' is not: please
correct this in setup.py
