43    
44    > make Loop.exe
45    
46    The executable is create by compiling and linking the files:
47    
48    Loop.cpp
49    My-Selection.cpp
50    My-Histos.cpp
51    
52    You can use My-Selection.cpp and My-Histos.cpp as a template to inplement your own
53    selection cuts and analysis.
54    More generally, you can compile and link Loop.cpp with your own source files (you need
55    to edit also the Makefile), where you should implement at least the following functions:
56    
57    bool Select(PamLevel2*);
58    void CreateHistos(PamLevel2*,TFile*);
59    void FillHistos(PamLevel2*);
60    void SaveHistos(TFile*);
61    
62    To know how to use Loop.exe, issue:
63  ./Loop.exe --help  ./Loop.exe --help
64    
65    (If you execute "make Loop-0.exe" the old example code, previously posted on the cvs,
66    is compiled and linked. This is not a very general example, better use the new one)
