Abstract
We present a new program package for calculating one-loop Feynman inte grals, based on a new method avoiding Feynman parametrization and the contraction due to Passarino and Veltman. The package is calculating o ne-, two- and three-point functions both algebraically and numerically to all tensor cases. This program is written as a package for Maple. An additional Mathematica version is planned later.
