+Note that sometimes ``SetEnv`` doesn't play well in this mod_python
+configuration, for reasons unknown. If you're having problems getting
+mod_python to recognize your ``DJANGO_SETTINGS_MODULE``, you can set it using
+``PythonOption`` instead of ``SetEnv``. Therefore, these two Apache directives
+are equivalent::
+
+    SetEnv DJANGO_SETTINGS_MODULE mysite.settings
+    PythonOption DJANGO_SETTINGS_MODULE mysite.settings
