Cool. I hadn't realized that the Bzr API was that flexible. Just a few questions:


1. Is the "sha1:" part necessary?

2. I need a way to search revisions according to the testament. One way I could do it is by producing a history log and doing a text search, but I wonder if there is a cleaner way to do that.


I will be happy to write a plugin for this. It will be a long time in coming because (a) I'm going away for two weeks and (b) I don't know a lot about Python or bzr. But this sounds like a straight forward plugin, so I'll do it.


Cheers,
Daniel.
