  FeynHiggs is a Fortran code for the calculation of the masses of the neutral
CP-even Higgs bosons in the MSSM up to two-loop order. It is based on the
complete diagrammatic on-shell results at the one-loop level, the leading
diagrammatic two-loop QCD contributions and further improvements taking into
account leading electroweak two-loop and leading higher-order QCD corrections.
The Higgs-boson masses are calculated as functions of the MSSM parameters for
general mixing in the scalar top sector and arbitrary choices of the parameters
in the Higgs sector of the model.
