[Monotone-devel] exploring ancestry

[Bruce Stephens]

It's been bothering me that I can't see a way to get a feeling for
what's in a repository.  

Tom Lord's arch has "tla ancestry" which provides a reasonably compact
summary of the ancestry of (normally) whatever's in the current
working directory.  It also provides "tla merges" showing where two
branches have been merged.  Neither of those really make much sense
for monotone, I suspect---not directly, anyway.  And neither is really
what I'd like anyway.

monotone has agraph, but that seems to include lots of manifests which
are likely to be of little importance (for a high level view, anyway).
Unless there's an option to agraph I haven't seen.

Anyway, I hacked something up to show what I think are interesting
nodes, and I ran it on my copy of the monotone database from off.net.
The resulting file (suitable for feeding to xvcg) is here
<http://www.cenderis.demon.co.uk/monotone.vcg>.  It has edge labels
(not shown unless you switch them on), indicating the number of hops
between nodes.

Does this seem like a useful option to add to agraph?  (Does agraph
already have such a thing?)  Are there any other useful ways to see
how all these certs are related?
