  FormCalc is a matrix-element generator that turns FeynArts amplitudes up to
one loop into a Fortran code for computing the squared matrix element. The
generated code can be run with FormCalc's own driver programs or used with
other `frontends', e.g. Monte Carlos. Major new or enhanced features in Version
4.1 are: treatment of external fermions, phase-space integration,
code-generation functions, extensions for the MSSM, the HadCalc frontend.
