I don't want to have to run the tests for 'zope.dublincore' in *every*
system which uses it:  I want to test 'zope.dublincore' in isolation,
and then use a well-tested, "known good" version of it in other
applications, which may not need or want the 'zope.app.testing' dependency.

If zc.buildout would grow support for either 'tests_require' or a
special 'extras_require' key, you could still have what you want without
forcing it on the rest of the world.
