+                      Electromagnetic PhysicsList
+                      ---------------------------
+ 
+     The example of physics list for standard electromagnetic physics 
+     package is presented in the subdirectory
+
+     electromagnetic_lists/standard
+
+     The corresponding files are PhysicsList.cc, .hh
+     Physics list is equipped by the messenger, which allows to set
+     cuts and to define modules of physics to be used. 
+     The following modules can be activated:
+
+     1. "standard"    - (alternative) standard EM physics (current version)
+     2. "g4v52"       - (alternative) standard EM physics (version G4 5.2p02)
+     3. "high_energy" - add high energy processes
+
+     To activate a specific module the UI command can be used:
+     "/testem/phys/addPhysics  title"
+     By default "standard" module is loaded.
+
+     The PhysicsList options can be defined via G4EmProcessOptions
+     class, the example of the usage is in the PhysicsList class
+
+     It is NOT assumed that files from this subdirectory will be
+     compiled directly. User can copy or link these files to 
+     his/her application, to modify this example according to the
+     particular application. It is assumed that user will add modules
+     to this PhysicsList.
+
+     This PhysicsList approach is used in tests of the standard 
+     electromagnetic package. Similar PhysicsLists can be found out
+     in advance examples.
+
+     The direct test of this PhysicsList is performed in the example 
+     examples/extended/electromagnetic/TestEm2
