# 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,
# because all parameters of it would be
# *untracked*
