 TVenus is an interface class between the event generator VENUS and       
 the ROOT system. The current implementation is based on VENUS 5.21

  VENUS is a Monte Carlo procedure to simulate hadronic interactions at   
  ultrarelativistic energies (hadron-hadron, hadron-nucleus, nucleus-     
  nucleus scattering).                                                    
                                                                          
  VENUS is based on Gribov-Regge theory (of multiple Pomeron exchange)    
  and classical relativistic string dynamics. A detailed description can  //  
  be found in a review article, published in Physics Reports 232 (1993)   
  pp. 87-299.                                                             
                                                                          
                                                                          

  Event generator Venus default constructor

  Event generator Venus normal constructor

  Event generator VENUS default destructor

  Generate next event

  Overloaded primary creation method. The event generator does
  not use the HEPEVT common block, and has not the PDG numbering scheme.

  Default primary creation method. It reads the /HEPEVT/ common block which
  has been filled by the GenerateEvent method. If the event generator does
  not use the HEPEVT common block, This routine has to be overloaded by
  the subclasses.
  The function loops on the generated particles and store them in
  the TClonesArray pointed by the argument particles.
  The default action is to store only the stable particles (ISTHEP = 1)
  This can be demanded explicitly by setting the option = "Final"
  If the option = "All", all the particles are stored.

  Set VENUS version number, the default is version 5.21

  Set VENUS ud quark production probability

  Set VENUS qq - qqbar probability

  Set VENUS cut off for Kmaror

  Set VENUS breaking procedure option

  iopbrk = 2 -> samba

  Set VENUS quark p_T distribution option
  ioptq = 1 -> exponential
  ioptq = 2 -> gaussian
  ioptq = 3 -> power

  Set VENUS mean quark transverse momentum
  with the energy dependence of mean transverse momentum of quarks:
  ptq1+ptq2*alog(e)+ptq3*alog(e)**2
  with e=sqrt(s)

  Set VENUS semihard interaction probability (not used if negative)

  Set VENUS cutoff parameter for p_t distr for semihard interactions
