Could be a serious problem... I can't remember if AGILe is specifying
the HepMC units properly, since the experiment version was always a
blocker on what was done. I think that Rivet should handle the incoming
HepMC units properly, but AGILe quite possibly doesn't write them.

One to fix -- asap -- before a new AGILe release. I'll take a look at it
tomorrow.
