Nature of problem:
This program package automatically generates a set of programs which is necessary for the calculation of the cross section and generation of simulated events in accordance with the specification of a physical reaction in the standard or minimus supersymmetric model.

Solution method:
Feynman graphs are generated in a combinatorial method. The generated code calculates Feynman amplitudes with spinor techniques.

Restrictions:
The program package is limited to the calculation of physical processes in Born approximation.

Running time:
It takes 10 seconds on IBM RS/6000 SP for code generation and compilation of generated code for 2 --> 3 MSSM process with 28 Feynman graphs and it takes 146 seconds for the integration over phase space for the same process.
