I'm not quite | familiar with Berkeley DB but it might be useful as a backend. Subversion provides its own client library for accessing the virtual file system. You won't have to work with the DB directly. It also provides an abstracted recover facility in one of its utilities (in case of stale locks). | > Imagine that images could be revisioned.

I said hybrid delta algorithm for binary diffs. I didn't say straightforward A - B diffing. Even if your images are black and white, they are most likely stored in a compressed format (if a Subversion based GIMP file format was ever invented), and if such compressed files are revisioned, no generic algorithm is going to give you a good difference. The whole Subversion thing was a far fetched *idea*. An alternative, which is most definitely going to be blown off as there are more reasonable ways of implementing the GIMP file format which are not far fetched. Mukund
