The Rivet validation framework

Rivet is principally a C++ framework for Monte Carlo event generator validation. It is built on the dual concepts of analyses - routines which implement published experiment analyses - and projections - routines which extract observables from event records. Rivet is designed to be efficient, via automatic caching of projection results for each event.
