We have a need to examine every document in a library that has major
versions turned on to see who checked out and edited documents, whether
or not they saved them as a major version. What we're looking for is a
detailed document history, perhaps more than is available via the UI.
Can anyone offer advice as to what the content db holds and what kind of
dev resource/expertise I need to engage to get a good look at it?

Please respond directly, as this is a time-sensitive thing and I get the
digest version from the list.
