The objective is to provide as accurate as possible a representationof event properties in a wide range of reactions, within and beyond theStandard Model, with emphasis on those where strong interactions play a role,directly or indirectly, and therefore multihadronic final states are produced.The physics is then not understood well enough to give an exact description;instead the program has to be based on a combination of analytical results andvarious QCD-based models. This physics input is summarized here, for areas suchas hard subprocesses, initial- and final-state parton showers, underlyingevents and beam remnants, fragmentation and decays, and much more. Furthermore,extensive information is provided on all program elements: subroutines andfunctions, switches and parameters, and particle and process data. This shouldallow the user to tailor the generation task to the topics of interest.
