After talking a bit with Andy yesterday, I have decided to try it a little 
differently, and I think it is working very well like this. There are 
indeed 8 different analysis identifiers, but only 7 lines of code-overhead 
for each of them (cf. JADE_OPAL_2000_S4300807.hh). I believe this is the 
most elegant solution for analyses where different histograms are filled 
with separate generator runs (as opposed to e.g. CDF_2001 where the _same_ 
(profile) histogram is filled with separate runs).

I am going to commit it to SVN now, and hope that you agree, that this is 
the better solution, which doesn't need any manual run-merging afterwards:

  Sherpa ECMS:=91 & rivet -a JADE_OPAL_2000_S4300807_91GEV -H Rivet.91 
fifo.hepmc2g
  [...]
  Sherpa ECMS:=189 & rivet -a JADE_OPAL_2000_S4300807_189GEV -H Rivet.189 
fifo.hepmc2g

  compare-histos $REFDATA/JADE_OPAL_2000_S4300807.aida ./Rivet.91.aida 
[...] ./Rivet.189.aida
  make-plots *.dat

Histograms for all CMS energies which I have run will end up as plots.

Cheers,
Frank
