     Geant4 - an Object-Oriented Toolkit for Simulation in HEP
     =========================================================

                         Basic Examples
                         ----------------

 The set of basic examples is oriented to "novice" users and covering many
 basic general use-cases typical of an "application"-oriented kind of
 development. 

 ExampleB1
   - Simple geometry with a few solids 
   - Geometry with simple placements (G4PVPlacement)
   - Scoring total dose in a selected volume user action classes
   - Geant4 physics list (QBBC)
   
 ExampleB2
   - Simplified tracker geometry with global constant magnetic field
   - Geometry with simple placements (G4PVPlacement) and parameterisation
     (G4PVParameterisation)
   - Scoring within tracker via G4 sensitive detector and hits
   - Geant4 physics list (FTFP_BERT) with step limiter
   - Started from novice/N02 example
   
 ExampleB3
   - Schematic Positron Emitted Tomography system 
   - Geometry with simple placements with rotation (G4PVPlacement)
   - Radioactive source 
   - Scoring within Crystals via G4 scorers
   - Modular physics list built via builders provided in Geant4

 ExampleB4
   - Simplified calorimeter with layers of two materials
   - Geometry with replica (G4PVReplica)
   - Scoring within layers in four ways: via user actions (a), via user own 
     object (b), via G4 sensitive detector and hits (c) and via scorers (d)
   - Geant4 physics list (FTFP_BERT)
   - UI commans defined using G4GenericMessenger
   - Started from novice/N03 example
