  CHARYBDIS is an event generator which simulates the production and decay of
miniature black holes at hadronic colliders as might be possible in certain
extra dimension models. It interfaces via the Les Houches accord to general
purpose Monte Carlo programs like HERWIG and PYTHIA which then perform the
parton evolution and hadronization. The event generator includes the
extra-dimensional `grey-body' effects as well as the change in the temperature
of the black hole as the decay progresses. Various options for modelling the
Planck-scale terminal decay are provided.
