I am a little overworked at this point, but this should be the right
direction to enable setuptools to create distributions whilst using the
information within setup.py (and without breaking any behaviour):
in pkg_resources
def register_finder(importer_type, distribution_finder):
"""Register `distribution_finder` to find distributions in sys.path
items
_distribution_finders[importer_type] = distribution_finder
def find_distributions(path_item, only=False):
"""Yield distributions accessible via `path_item`"""
importer = get_importer(path_item)
finder = _find_adapter(_distribution_finders, importer)
return finder(importer, path_item, only)
.
