+ The Rivet project (Robust Independent Validation of Experiment and
+ Theory) is a toolkit for validation of Monte Carlo event
+ generators. It provides a large (and ever growing) set of
+ experimental analyses useful for MC generator development,
+ validation, and tuning, as well as a convenient infrastructure for
+ adding your own analyses. Rivet is the most widespread way by which
+ analysis code from the LHC and other high-energy collider
+ experiments is preserved for comparison to and development of future
+ theory models.
