WOPPER, version 1.5: A Monte Carlo event generator for e+ e- ---> (W+ W-) ---> 4 f + n gamma at LEP-2 and beyond

We describe the new version of the Monte Carlo event generator WOPPER for four fermion production through W-pairs including resummed leading logarithmic QED radiative corrections. Among the new features included are singly resonant background diagrams and anomalous triple gauge boson couplings.
