I don’t know why setuptools provides pkg_resources, implements another

sqlalchemy.contrib namespace have to be declared by using
pkgutil.extend_path, because it is a part of Python standard library so
it don’t force users to install setuptools.
The vast majority of packages using namespaces that I have seen support
both with this snippet:
try:
__import__('pkg_resources').declare_namespace(__name__)
except ImportError:
from pkgutil import extend_path
__path__ = extend_path(__path__, __name__)
I would suggest that SQLAlchemy does the same thing.
