** Updating
The use of submodules make things somewhat different because git does not
support recursive operations: submodules must be taken care of explicitly by
the user.
If you have git at version 1.8.2 or later, the command
$ git submodule update --recursive --remote
will be useful for updating to the latest version of all submodules.
Under earlier versions, use of submodules make things somewhat different
because git does not yet support recursive operations: submodules must be
taken care of explicitly.
