eic-smear provides a fast, parameterized detector-response smearing library and ROOT-based analysis tree tools for EIC physics studies, reading generator output (Pythia, Djangoh, Milou, Pepsi, Rapgap, Sartre, DPMJet, HepMC) and applying configurable detector acceptance and resolution models. Pythia6-dependent code paths are not built here (no pythia6 in hep-forge).
