Miniguide PYTHIA

The aim of this note is to make the PYTHIA long description more attractive i. e. to help students, new comers and hurried physicists to be quickly and fully efficient in generating pp physics events with PYTHIA 6.1 To moderate the size of this miniguide, supersymmetry has been completely neglected so that readers interested in supersymmetry should consult the SPYTHIA reference manual or S. Mrenna s publication. For the very specific points where PYTHIA 5.7 and PYTHIA 6.1 differ a special highlighted warning note is given. This miniguide is, thus, valid for both releases PYTHIA 5.7 and PYTHIA 6.1 but user should consider, as does this note, PYTHIA 6.1 as standard.
