  Lelaps is a fast detector simulation program which reads StdHep generator
files and produces SIO or LCIO output files. It swims particles through
detectors taking into account magnetic fields, multiple scattering and dE/dx
energy loss. It simulates parameterized showers in EM and hadronic calorimeters
and supports gamma conversions and decays. In addition to three built-in
detector configurations, detector descriptions can also be read from files in
the new GODL file format.
