This whole script is a no-op now. Are you still keeping this script because you
want to reuse it soon? If so, put a comment about that in the change
description. Otherwise, remove the postbuild step that runs it and delete it,
and if we need it again in the future, we can resurrect it from version history.

We'll need this again for the Google Chrome Helper NLV.app, so I want to leave
this in as a no-op.
