 The directory structure of your simulation area, 
 $HOME/tutorial/  in this case, should be as follows:

 GNUmakefile : where appear the name of the executable, 
               in this case myMain;
 
 include/ : where all the header files (.hh, .h, .icc) stay;

 src/ : where all the corresponding source or implementation
        files (.cc) stay.

 After you have setup your environmental variables, to build 
 the executable type:     
                        gmake

 which produces the executable (myMain) in: $G4WORKDIR/bin/$G4SYSTEM.
 Suppose that your PATH include $G4WORKDIR/bin/$G4SYSTEM
 you can execute it by simply typing its name, myMain. 
 You have two possibility:
    i)  myMain macro.g4     to run in batch;
   ii)  myMain              to run interactively,
 
 Other files or subdirectories can be added if you want.
 In this case, the  training/  subdirectory contains
 the exercises and their solutions.

 NB) At the very beginning, you will not find the GNUmakefile,
     and the directories include/ and src/ are empty.
     It is the purpose of the  0_start/  exercise
     to provide it, and to fill properly the directories
     include/ and src/. See below.

 ----------------------------------------------------------

 Here how to use training directory is organized.
 training/ has two subdirectories:
 exercises/   where you find the test of the exercises,
              as ToDo.txt files;
 solutions/   where you find the files that should be
              created/modified in order to solve the exercises.
 The subdirectory structure of exercises/ and solutions/
 is exactly the same.

 In order to use a solution to a given exercises, for
 example 0_start/, you have to do the following:

   i) copy the  *.hh  files that are in: 
             tutorial/training/solutions/0_start/ 
      into:  tutorial/include/

  ii) copy the  *.cc  files, excluding myMain.cc, 
      that are in: 
             tutorial/training/solutions/0_start/ 
      into:  tutorial/src/

 iii) copy all other files (myMain.cc, GNUmakefile,
      macro files  *.g4 ) that are in: 
             tutorial/training/solutions/0_start/ 
      into:  tutorial/

 NB) For Windows only: in the analysis exercises
     ( 10_analysis/ , 10b/ , 10c/ ) you have to use
     Jas rather than Anaphe: this means, in practice,
     that you have to move any file which ends with
     the string  -win32-Jas  to a file with the same
     name without such string, for example:

       cd tutorial/solutions/10_analysis/
       mv GNUmakefile-win32-Jas GNUmakefile
       mv MyAnalysis.cc-win32-Jas MyAnalysis.cc
