  A program for the calculation of the total Higgs production cross section via
gluon fusion at hadron colliders including next--to--leading order QCD
corrections is presented. It is suitable especially for Standard Model Higgs
bosons and the neutral Higgs particles of the minimal supersymmetric extension.
The program provides a model--independent calculation for scalar [\CP--even] as
well as pseudoscalar [\CP--odd] Higgs bosons including the contributions of
virtual top and bottom quarks inside the loop coupled to the Higgs particles.
The relevant input parameters can be chosen from an input file. As a special
case the minimal supersymmetric extension of the Standard Model can be
investigated. The corresponding couplings are implemented including the leading
higher order corrections.
