# Little helper script I use for performance tuning 
# PS Application Engine programs. This program expects
# to read an AE log file. It spits out a listing if 
# all the steps that were executed, and the cumulative
# run times. This helps to identify steps that may not
# run excessively long for a single execution, but may 
# be run over and over, usually in a loop. Sometimes 
# these are steps that run in a fraction of a second,
# but if the process loops through it millions of times
# a minor improvement in performance can be significant.
