Make a separate module with all the config stuff in it, and import
that module everywhere you need it. Just make sure you do "import
settings" and not "from settings import *". The behavior is different.
In the first case, one instance of the module is shared among every
module that imports it, so any changes you make will appear in all
modules. IN the second case, the current values in settings.py are
copied into the local namespace. Changes made in one module won't
appear in the other modules.
