#This fragment is used to add the SimpleMemoryCheck
#and Timing services output to the log for the Performance Suite profiling.
#It is meant to be used with the cmsDriver.py option
#--customise in the following fashion:
#E.g.
#cmsDriver.py MinBias.cfi -n 50 --step=GEN,SIM --customise=Validation/Performance/TimeMemoryInfo.py >& MinBias_GEN,SIM.log&
#Note there is no need to specify the "python" directory in the path.
