Some important comments for FeynHiggs2.1:

(not applicable for FeynHiggs2.X, X>1)

• To unpack the .sfx files, type ./FeynHiggs-2.1beta.sfx -x (you need uudecode)
• LoopTools is required for the evaluation of some Higgs decay widths. Without LoopTools, the decays to gamma gamma and gg will be evaluated to zero. Thus we recommend the installation of LoopTools. However, it works without, just two decay modes are zero.
• The evaluation of (g-2)_mu contains only the leading corrections at the two-loop level. If you want all corrections as evaluated in hep-ph/0312264 (by S. Heinemeyer, D. Stöckinger, G. Weiglein) you have to download the additional package gm2.uu. Put it in your FeynHiggs home directory, unpack it with csh gm2.uu and follow the instructions in the README.
