  We present a new program (iHixs) which computes the inclusive Higgs boson
cross-section at hadron colliders. It incorporates QCD corrections through
NNLO, real and virtual electroweak corrections, mixed QCD-electroweak
corrections, quark-mass effects through NLO in QCD, and finite width effects
for the Higgs boson and heavy quarks. iHixs can be used to obtain the most
precise cross-section values in fixed order perturbation theory in the Standard
Model. In addition, it allows for a consistent evaluation of the cross-section
in modified Higgs boson sectors with anomalous Yukawa and electroweak
interactions as required in extensions of the Standard Model. iHixs is
interfaced with the LHAPDF library and can be used with all available NNLO sets
of parton distribution functions.
