[Distutils] pkg_resources: import string

I was thinking some more about WSGI configuration, and much configuration involves some "import a string" routing, that looks like importstring("os.path:sep") or somesuch. But we implement it slightly differently. And maybe there could be a PEP and whatnot, but I don't even know what module that would go into, and it would just have to be backported for a long time anyway... but then it seemed like it would fit nicely into pkg_resources, and just about anywhere I want to import strings I expect pkg_resources to be around as well. -- Ian Bicking / ianb@colorstudy.com / http://blog.ianbicking.org
