        I don't think we have a tool for processing this data in Jikes RVM itself.  I'm sure that such a tool exists (Matthew? Eliot?); perhaps it could be contributed to the research archive to make it easier to find (then we could link to the tracker item from the userguide entry on GCTrace facilities).
