"""Usage: %prog <commit>*
Given a commit, finds the release where it first appeared (e.g. 47.0.2500.0) as
well as attempting to determine the branches to which it was merged.
Note that it uses the "cherry picked from" annotation to find merges, so it will
only work on merges that followed the "use cherry-pick -x" instructions.
