We're still only shipping Open MPI as a whole as our official product,
right? More specifically: we're not intending to ship OPAL
independently, right? If other projects want to pick up OPAL
themselves and use it (e.g., via SVN checkouts, Mercurial clones,
official OMPI tarballs, etc.), that's fine. But I'd be opposed to
creating a 2nd official distribution that was OPAL-only.
