In an automated build environment I need to be able to make eggs which depend on non-released "testing" eggs. These are all published to a web-server operated by my team. I know that it's possible to globally change the default URLs of the "--find-links" easy_install option by editing the distutils.cfg file, however I want a fully automated process which will validate a system's configuration and determine if the test-egg URL have been added to the system. If not, I want my build process to fail with an explicit error emssage. Other than by directly inspecting and parsing this file, is there a programatic way to find which hosts have been configured in the distutils.cfg file? Ideally I'd like to access this information via pkg_resources. Any suggestions?
