Thanks for the kind words.  It wasn't too much fun, and part of it is
that the lp web interface is really not very helpful in certain spots.
 But my ignorance of certain aspects of the tools obviously was the
main problem.

In the end it worked pretty well I think, and we didn't end up losing
any history, which is the key point.  The web view is fundamentally
not very good since it doesn't know how to show true branches, but at
least the full history *is* there (bzr log/viz show it all).  This is
much better than the alternative of just dumping in a big commit
message with the old log but no real merge step-by-step history.

Sounds like a perfect plan, thanks.

Yup.

Yup.

I'm thinking first and foremost about how to do better testing on
trunk, so we can painlessly absorb all existing ip1 tests, AND improve
our testing practices for the old code as well.  That will be my
immediate focus for the time I can devote to ipython in the coming
days.

Great.  Soon we should also think about a way to reduce the wiki/docs
duplication.  The new work on the numpy docs wiki site could be a
start.  But let's go with what we have for now: that might be a topic
for a sprint at scipy, to generalize that machinery for other projects
to use.

I should close this by giving a huge thanks to everyone not only for
recent feedback, but especially for keeping the project alive and
moving despite the difficult split created by my short-sightedness.
In particular, if it weren't for Ville's steady pushing of the trunk,
I'm afraid we wouldn't have a live project to merge again back into,
and if it weren't for Brian and Min's patience on endless discussions
with me for ip1, we would have nothing to bring :)  So really, thanks
to all for helping this stay alive and interesting, now we'll move
forward.

Regards,
