[Zope] APE and version control?

Hi Shane, I'm a bit interested in what you meen by "apply version control to your objects". How would this work? Ape/doc/outline.txt : """ Finally, the framework is useful for many purposes outside ZODB. Once you have built a system of mappers, you can use those mappers to import and export objects, synchronize with a data store, and apply version control to your objects. The concepts behind ApeLib open exciting possibilities.
