that can be read in and processed further by PYTHIA 8. 
The advantage is that then the MadGraph 5 phase space generator 
can be used, which opens up for processes with more than three 
particles in the final state. The disadvantages are that it is less
easy to mix and match with existing PYTHIA processes, and that one 
needs to regenerate and store large LHEF files for different
kinematics cuts or parameter values.
