Is there a way to distribute a WSGI application that will work out of the box with any server and that will be configurable using the server's built-in features only?
This means that the only configuration file the administrator would have to touch would be the server's configuration file. It wouldn't be necessary to write a custom WSGI script in Python.

mod\_wsgi adds configuration variables set with `SetEnv` to the WSGI environ dictionary that gets passed to the app, but I didn't find a way to do something similar with Gunicorn or uWSGI. Using `os.environ` works with Gunicorn and uWSGI but not with mod\_wsgi because `SetEnv` doesn't affect `os.environ`.
