  We have combined a new systematic calculation of mesonic matrix elements at
O(p^6) from an effective chiral lagrangian approach using Wilson coefficients
taken from [G.Buchalla, A.J.Buras, M.E.Lautenbacher, Rev.Mod.Phys. 68 (1996)
1125], derived in the framework of perturbative QCD, and restricted partly by
experimental data.
  We derive complete expressions for K --> 2pi amplitudes and give new
estimates for epsilon'/epsilon.
