Abstract: GRAPE-Dilepton is a Monte Carlo event generator for dilepton production in ep collisions. The cross-section calculation is based on the exact matrix elements. The Feynman amplitudes were generated by the automatic calculation system GRACE. In this version, all the electroweak diagrams at tree level are included except for proton-Z couplings and lepton pair production through photon radiation from the proton. This generator has an interface to PYTHIA to get complete hadronic final states.
