  We overview the detailed analysis of epsilon'/epsilon within the Standard
Model, presented in ref. 1. When all sources of large logarithms are
considered, both at short and long distances, it is possible to perform a
reliable Standard Model estimate of epsilon'/epsilon. The strong S-wave
rescattering of the final pions has an important impact on this observable. The
Standard Model prediction is found to be Re(epsilon'/epsilon) =(1.7 +-
0.9)*10^{-3}, in good agreement with the most recent experimental measurements.
A better estimate of the strange quark mass would reduce the uncertainty to
about 30%.
