\section etr_s1 Description

  Geant4 TestEm10 adapted to Virtual Monte Carlo.

  It demonstrates use of Geant4 transition radiation physics.

  The users have to define the radiator envelope with
  a material defined as a mixture of the foil and the gas material.
  The radiator properties should be then set via the Geant4  VMC
  command
\verbatim
/mcDet/setRadiator volumeName xtrModel foilMaterial gasMaterial foilDensity gasDensity foilNumber
\endverbatim

  For more details see the Geant4 example description at:
  - http://geant4.web.cern.ch/geant4/UserDocumentation/Doxygen/examples_doc/html/ExampleTestEm10.html

\section etr_s2 Macros

  For running example with G4:
  <pre>
  \link       TR/load_g4.C load_g4.C      \endlink - macro to load the libraries to run the example with Geant4
  \link        TR/run_g4.C run_g4.C       \endlink - macro for running example 
  \link      TR/g4Config.C g4Config.C     \endlink - configuration macro - G4 native geometry navigation (default)
  \link  TR/g4tgeoConfig.C g4tgeoConfig.C \endlink - configuration macro - G4 with TGeo navigation 
   g4config.in   - macro for G4 configuration using G4 commands (called from g4Config.C)
   g4config2.in  - macro for G4 post-init configuration using G4 commands (called from run_g4.C)
   g4vis.in      - macro for G4 visualization settings (called from set_vis.C) 
  </pre>

  For running example with G3:
  <pre>
  \link      TR/load_g3.C load_g3.C     \endlink - macro to load the libraries to run the example with Geant3
  \link       TR/run_g3.C run_g3.C      \endlink - macro for running example 
  \link TR/g3tgeoConfig.C g3tgeoConfig.C\endlink - configuration macro for G3 with TGeo geometry
  </pre>

  Common macro (called by run_g3.C/run_g4.C):
  <pre>
  \link TR/set_vis.C set_vis.C\endlink - setting visualization
  </pre>

\section etr_s4 To run example 

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

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

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