WOPPER, Version 1.5: A Monte Carlo Event Generator for e+e- to (W+W-) to 4f + n gamma at LEP2 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.
