        -------------------------------------------

 Examples in this directory demonstrate various ways of primary event
 generation.

exGPS
-----

This example demonstrates the usage of G4GeneralParticleSource for generating 
primary incident particle according to user defined distributions.

particleGun
------------

These examples demonstrate 4 ways of the usage of G4ParticleGun shooting
primary particles in different cases.

HepMC
