@untitaker, right.  If `DEBUG` is defined in a `BaseConfig` as `True`, then you load `ProductionConfig`and it is `False`, `DEBUG` will be false.  Hence: "it will use the setting defined in the last import" 

Maybe I can make that clearer?  Any suggestions?  Would it be best to put a link to the configuration docs [here](http://flask.pocoo.org/docs/config/) and they can read more if they are confused?
