# This tool tabulates operator and function activity. It is called as
#
# exprsum prog
#
# where prog is a program compiled under MT Icon whose events are to
# be tabulated.
#
# The options supported are:
#
# -o s write output to file s; default &output.
#
# -t record time spent in monitoring.
#

#
# Requires: Version 9 MT Icon and event monitoring.
