+ <longdescription>
+ A package for evaluation of scalar and tensor one-loop integrals
+ based on the FF package by G.J. van Oldenborgh.
+ It features an easy Fortran, C++, and Mathematica interface
+ to the scalar one-loop functions of FF and in addition provides
+ the 2-, 3-, and 4-point tensor coefficient functions.
