The file ³batch² explicitly sets to 2, but I noticed that not all your
scripts concatenate the ³batch² file. Bench.sh does, bench2.sh does, bench3
doesn¹t, and bench4-.sh (and subfile bech4-sub). Maybe I am tired at this
hour and am missing it as well. It seems like some are 0 ply and some are 2
ply?
