%description
 WHIZARD is a program system designed for the efficient calculation of multi-particle 
 scattering cross sections and simulated event samples.
Tree-level matrix elements are generated automatically for arbitrary partonic 
processes by using the Optimized Matrix Element Generator O'Mega. Matrix elements 
obtained by alternative methods (e.g., including loop corrections) may be interfaced
 as well. The program is able to calculate numerically stable signal and background
  cross sections and generate unweighted event samples with reasonable efficiency 
  for processes with up to eight final-state particles; more particles are possible.
   For more particles, there is the option to generate processes as decay cascades 
   including complete spin correlations. Different options for QCD parton showers are available.
