Confused about the sub-modules

[Edward Z. Yang]

Once the commit is upstream, I just checkout a newer commit from
master and then commit it as a submodule update. Maybe it's
wrong but no one has ever told me otherwise.  Around release
time the release manager makes sure all the libraries correspond to
actual releases.
