     # however, an at least "empty mixing" need to be present if you

     # want to perform Ecal/Hcal/CSC/DT digitization - those explicitely

     # require presence of CrossingFrame in the edm::Event

     #

     # alternatively, you can set averageNumber=0 if you don't want

     # to model the pileup

     #

     # to the secsource/PoolRASource, you can give just 1 file or more;

     # this files will make a "concatinated buffer", which will go circular

     # until the loop of primary events is done - thus, it'll never run out

     #

     # WARNING: you can only give miltiple files, if they're generated with

     #          identical sets of tracked parameters;

     #          for example, you canNOT give a file made with a single muon

     #          gun and a file made with a single pion gun, because PartID

     #          is a *tracked* parameter in the gun's PSet;

     #          however, you can merge together files made with other generators,

     #          for example, PythiaSource, because all parameters of it would be

     #          *untracked*
