We present a subtraction scheme for computing jet cross sections inelectron-positron annihilation at next-to-next-to-leading order accuracy inperturbative QCD. In this first part we deal with the regularization of thedoubly-real contribution to the NNLO correction.Comment: 50 pages, LaTeX file, uses pstrick
