\section gflash_s1 Description

  The Geant4 gflash example adapted to Virtual Monte Carlo.

  It demonstrates the use of the Geant4 GFLASH parameterisation library. It uses the GFLASH equations
  (hep-ex/0001020, Grindhammer & Peters) to parametrise electromagnetic showers in matter

  The Gflash model is not used when running the example with Geant3.

  See also the Geant4 example description at:

\section gflash_s2 Macros

  For running example with G4:
  <pre>
  \link       Gflash/load_g4.C load_g4.C      \endlink - macro to load the libraries to run the example with Geant4
  \link        Gflash/run_g4.C run_g4.C       \endlink - macro for running example
  \link      Gflash/g4Config.C g4Config.C     \endlink - configuration macro for G4 native geometry navigation (default)
  \link  Gflash/g4tgeoConfig.C g4tgeoConfig.C \endlink - configuration macro for G4 with TGeo navigation
  \link    Gflash/set_g4_vis.C set_g4_vis.C   \endlink - setting Geant4 visualization (called by run_g4.C)
   g4config.in   - macro for G4 configuration using G4 commands (called from g4Config.C)
   g4vis.in      - macro for G4 visualization settings (called from set_g4_vis.C)
  </pre>

  For running example with G3:
  <pre>
  \link      Gflash/load_g3.C load_g3.C     \endlink - macro to load the libraries to run the example with Geant3
  \link       Gflash/run_g3.C run_g3.C      \endlink - macro for running example
  \link Gflash/g3tgeoConfig.C g3tgeoConfig.C\endlink - configuration macro for G3 with TGeo geometry(default)
  \link   Gflash/set_g3_vis.C set_g3_vis.C  \endlink - setting Geant3 TGeo visualization (called by run_g3.C)
 </pre>

\section gflash_s3 To run example

  <pre>
  With G4:
  root[0] .x \link Gflash/load_g4.C load_g4.C\endlink
  root[1] .x \link Gflash/run_g4.C run_g4.C\endlink

  With G4 + TGeo navigation:
  root[0] .x \link Gflash/load_g4.C load_g4.C\endlink
  root[1] .x \link Gflash/run_g4.C run_g4.C\endlink(\link Gflash/g4tgeoConfig.C "g4tgeoConfig.C"\endlink);

  With G3 + TGeo:
  root[0] .x load_g3.C
  root[1] .x run_g3.C
  </pre>
