+A helper to allow configuring the modules dynamically.
+
+Usage:
+
+  from my.cfg import config
+
+After that, you can set config attributes:
+
+  from types import SimpleNamespace
+  config.twitter = SimpleNamespace(
+      export_path='/path/to/twitter/exports',
+  )
+"""
+# TODO later, If I have config stubs that might be unnecessary too..
+
+from . import init
+
+import my.config as config
