"""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.
