#! /bin/sh
#
# Collects multiple outputs of x11perf.  Just feed it a list of files, each
# containing the output from an x11perf run, and this shell will extract the
# object/second information and show it in tabular form.  An 80-column line
# is big enough to compare 4 different servers.
#
# This script normally uses the results from $1 to extract the test label
# descriptions, so you can run x11perf on a subset of the test and then
# compare the results.  But note that x11perffill requires the labels file
# to be a superset of the x11perf results file.  If you run into an ugly
# situation in which none of the servers completes the desired tests
# (quite possible on non-DEC servers :), you can use -l <filename> as $1 and
# $2 to force x11perfcomp to use the labels stored in file $2.  (You can run
# x11perf with the -labels option to generate such a file.)
