Both colour-singlet and colour-octet contributions are included. We discuss in detail the use of covariant projectors in dimensional regularization, the structure of soft-gluon emission and the overall finiteness of radiative corrections. We compare our approach with the\n NLO version of the threshold-expansion technique recently introduced by\n Braaten and Chen. Most of the results presented here are new.
