This was on the Les Houches workshop server with a setup script that
does much more than just Rivet (i.e. Sherpa, Herwig++, Pythia6, Pythia8,
AGILe), so it was customized and I hadn't expected the colon to be of
any relevance.

may also be re-written as s-1, where s is the number of planes owned
that would result in separation from your partner.       -- Veluminati
