"""WAeUP interfaces.

interfaces and components were first introduced for the Zope3 architecture.
However they can also be used for Zope 2.9 applications too such as CMF and CPS.
Currently they are used by the GenericSetup tool to adapts persistent objects
that are worth im- / exporting to their dedicated XMLAdapter.

In our case, we want the state of our vogon tool to be GenericSetup aware.
Please see the exportimport.py file for more details on the corresponding
XMLAdapter.
