Nature of problem:
Determining properties of the potential, calculation of mass spectrum, couplings, decay widths, oblique parameters, muon g - 2, and collider constraints in a general two-Higgs-doublet model.

Solution method:
From arbitrary potential and Yukawa sector, tree-level relations are used to determine Higgs masses and couplings. Decay widths are calculated at leading order, including FCNC decays when applicable. Decays to off-shell vector bosons are obtained by numerical integration. Observables are computed (analytically or numerically) as function of the input parameters.

Restrictions:
CP-violation is not treated
