   <hidden TTP02-13  Two-loop amplitudes with nested sums: Fermionic contributions to e+e- --> q qbar g > We present the calculation of the $\nf$-contributions to the two-loop
 amplitude for $e^+e^-\to q \qb g$ and give results for the full one-loop
 amplitude to order $\eps^2$ in the dimensional regularization parameter.
 Our results agree with those recently obtained by Garland et al..
 The calculation makes extensive use of an efficient method based on
 nested sums to calculate two-loop integrals with arbitrary powers
 of the propagators.  The use of nested sums leads in a natural way to 
 multiple polylogarithms with simple arguments, which allow a 
 straightforward analytic continuation.
