  SPYTHIA is an event level Monte Carlo program which simulates particle
production and decay at lepton and hadron colliders in the Minimal
Supersymmetric Standard Model (MSSM). It is an extension of PYTHIA 5.7, with
all of its previous capabilities. This paper is meant to supplement the
PYTHIA/JETSET user manual, providing a description of the new particle
spectrum, hard scattering processes, and decay modes. Several examples of using
the program are provided.
