+ * The initial parameters of the particle(s) to simulate are given in the 
+ * LEMuSRPrimaryGeneratorAction class. This mandatory class work in interplay
+ * with the LEMuSRParticleGun to create each new event of the simulation.
+ * 
+ * An event is the track of one particle and all the particles created during its
+ * evolution in the detector, by decay, scattering or any other kind of process.
+ * cf. \ref pga.
