Detailed Description

The Geant4 VMC example Monopole test application.

The Geant4 VMC test application with explicitely instantiated TGeant4 and linked with all libraries.

Usage:
testMonopole
  [-g4g,  --g4-geometry]:        Geant4 VMC geometry option
  [-g4pl, --g4-physics-list]:    Geant4 physics list selection
  [-g4sp, --g4-special-physics]: Geant4 special physics selection
  [-g4m,  --g4-macro]:           Geant4 macro
  [-g4m2, --g4-macro2]:          Geant4 macro run after initialization
  [-g4vm, --g4-vis-macro]:       Geant4 visualization macro
  [-rm,   --root-macro]:         Root macro
  [-v,    --verbose]:            verbose option (yes,no)

Note that the g4* and g3* options are available only when built
with the corresponding VMC_WITH_Geant4 or VMC_WITH_Geant3 option.
Root macro with arguments should be passed within '', eg.
 --root-macro 'test_Monopole_1.C("",kFALSE)'
