Among the new features included are singly resonant background diagrams and anomalous triple gauge boson couplings.36 pages, standard LaTeX (8 PostScript figures), corrected the sign in the relation of z_Z and g_5^Z, corrected a few typos and included the Feynman diagrams in PostScriptHigh Energy Physics - PhenomenologyHigh Energy Physics - ExperimentWOPPER, Version 1.5: A Monte Carlo Event Generator for e+e- to (W+W-) to 4f + n gamma at LEP2 and beyondtext
