"""WAeUP Tool XML Adapter.

An XML adapter tells the GenericSetup machinery howto im- / export persistent
configuration that is relative to a specific CMF component such as our WAeUP
Tool.

GenericSetup uses the Zope3 interfaces and components machinery to find the
right XML adapter for the right object. This is why we flagged our waeup tool
with the `implements(IWAeUPTool)` class attribute and made an adapter
association in the `configure.zcml` file.
