Detailed Description

Example program for scanning event-weights of Monte Carlo files
containing a given set of primaries.

The list of possible options for the flux includes:

   -@ zero         <type>
   -@ flat         <type>  <value>
   -@ powerlaw     <type>  <normalisation>  <spectral index>
   -@ atmospheric  <type>
