Subject: Re: [OMPI devel] IOF redesign: cmd line options
From: Ralph Castain (rhc_at_[hidden])

Sorry - should have made that clear. Yes, there is a --xml flag
already in the system.

If you specify --xml, the output is wrapped in XML tags. You don't
need to also specify --tag-output...the --xml tag implies that option.

Thanks for reminding me, though ;-)
