3"""WAeUP Tool XML Adapter.
4
5An XML adapter tells the GenericSetup machinery howto im- / export persistent
6configuration that is relative to a specific CMF component such as our WAeUP
7Tool.
8
9GenericSetup uses the Zope3 interfaces and components machinery to find the
10right XML adapter for the right object. This is why we flagged our waeup tool
11with the `implements(IWAeUPTool)` class attribute and made an adapter
12association in the `configure.zcml` file.
