HepMCEx01
HepMCEx01 is based on ExampleN04, which has a simplified collider detector geometry. Only part of the primary generator action is replaced with new one. This example demonstrates the following features.
1. HepMC interface

HepMCEx02
This example demonstrates how to interface primary particles in Geant4 with various event generators via the HepMC Monte Carlo event interface. This is another example having the same generator action as HepMCEx01, but much simpler user control.

MCTRUTH using HepMC
This example demonstrates a mechanism for Monte Carlo truth handling using HepMC as the event record. The user does not interact directly with the HepMC classes but with the MCTruthManager class which takes care with storing all the necessary information about particles, vertices and relations between them. A specialized tracking action is used to test whether given particle is to be stored or not. The decision criteria for storing particle are configurable via the MCTruthConfig class.
