Functions implemented for the five $\\gamma^\\star\\gamma^\\star$ structure functions now include several ans\\\"atze of the total hadronic cross section based on the BFKL--Pomeron and various Regge-like models. In addition, structure functions for resonance formation are included with full dependence on the two photon virtualities $Q_1^2$ and $Q_2^2$ as given in the constituent-quark model.
