  The package aITALC has been developed for the automated calculation of
radiative corrections to two-fermion production at $e^+ e^-$ colliders. The
package uses Diana, Qgraf, Form, Fortran, FF, LoopTools, and further unix/linux
tools. Numerical results are presented for $e^+e^- \to e^+e^-, mu^+mu^-, b
\bar{s}, t \bar{c}$.
