Subject: Re: [OMPI devel] -display-map behavior in 1.3
From: Ralph Castain (rhc_at_[hidden])

Should be doable....

Since the output was going to stderr, we just let it continue to do so and
tagged it. I think I can redirect it when doing xml tagging as that is
handled as a separate case - shouldn't be too hard to do.
