copy_revs ?

Barrie: from your email reply, and what I can gather from the
documentation, I understand that the source driver has to produce some
information about all the revisions which can be found in the repository.

However I don't understand where and how it should do it. Which functions
should be doing the task and what structure they should return?

This all seems to evolve around copy_revs. It looks like the VSS and the
P4 sources are doing the job in copy_revs .. which I don't see mentioned
in the documentation. Actually, there is one spot in the source where it
says copy_revs is deprecated..
