Then we present a subtraction scheme that can be defined at any order in perturbation theory. We give a status report of the implementation of the method to computing jet cross sections in electron-positron annihilation at the next-to-next-to-leading order accuracy.talk presented at the 8th International Symposium on Radiative Corrections, Florence, Italy, October 1-5, 2007High Energy Physics - Phenomenologytext
