3. Step 2) can be repeated as many times as desirable. The output/version names can be whatever.

4. Detailed numerical test of two versions (A and B):

   • run ./compare_multiple <version A> <version B>

5. Graphical comparison of standard plots:

   • cd plots-root
   • edit file make_plots.cc: in function make_plots define the versions (and their line color/style) you wish to plot
   • run root -l -q make_plots.cc
