It consists of five parts:\n i) a graphical user interface\n ii) routines for generating diagrams from particle input\n iii) procedures for calculating one-loop integrals both analytically and numerically\n iv) routines for massive two-loop integrals\n v) programs for numerical integration of two-loop diagrams. The package relies on the application of parallel space techniques. The treatment of tensor structure and the separation of UV and IR divergences in analytic expressions is described in this scheme.
