tools for making upstreaming / backporting easier in git

Hi all,

Back in April, I announced a couple of scripts I'd written to wrap
around git-cherry and git-notes, which help when you have more than a
trivial number of commits to upstream / backport from one branch to
another.  Since then I've improved these scripts, and also written a
higher-level CLI which should make the whole process pretty easy.

Yesterday I finally finished a blog post with all the details:

These tools worked pretty well for me and my team, but no doubt some
people will have ideas how to improve them, or have different
techniques for tackling the problem.  Either way, I hope this is of
interest, and I'd be very interested to hear what people think!

Cheers,
Adam
