Rivet is only able to see weights via the HepMC GenEvent object, which 
contains a vector of weights. Rivet currently only uses the first of 
these, as the return value from the Rivet::Event::weight() method.

So if you can set appropriate inverse weights in the Py8 -> HepMC 
interface, then Rivet should be ok.

Thanks for the info, Torbjorn... I look forward to slightly more 
out-of-the-box implementation in some future release, though!
