# Modification Log:
# $Header: run,v 5.2 88/01/12 06:23:43 kenj Exp $
# Ken McDonell, Computer Science, Monash University
# August 1, 1983
# 3/89 - Ben Smith - BYTE: globalized many variables, modernized syntax
# 5/89 - commented and modernized. Removed workload items till they
# have been modernized. Added database server test.
# 11/14/89 - Made modifications to reflect new version of fstime
# and elimination of mem tests.
# 10/22/90 - Many tests have been flipped so that they run for
# a specified length of time and loops are counted.
# 4/3/91 - Cleaned up and debugged several test parameters - Ben
# 4/9/91 - Added structure for creating index and determing flavor of UNIX
# 4/26/91 - Made changes and corrections suggested by Tin Le of Sony
# 5/15/91 - Removed db from distribution
# 4/4/92 Jon Tombs <jon@robots.ox.ac.uk> fixed for GNU time to look like
# BSD (don't know the format of sysV!)
# 12/95 - Massive changes for portability, speed, and more meaningful index
# DCN David C Niemi <niemi@tux.org>
# 1997.06.20 DCN Fixed overflow condition in fstime.c on fast machines
# 1997.08.24 DCN Modified "system", replaced double with
# whetstone-double in "index"
# 1997.09.10 DCN Added perlbench as an Exhibition benchmark
# 1997.09.23 DCN Added rgooch's select as an Exhibition benchmark
# 1999.07.28 DCN "select" not compiled or run by default, because it
# does not compile on many platforms. PerlBench also
# not run by default.
# 2007.09.26 IS Huge rewrite -- see release notes in README.
# 2007.10.12 IS Added graphics tests, categories feature.
# 2007.10.14 IS Set and report LANG. Added "grep" and "sysexec".
# 2007.12.22 IS Tiny fixes; see README.
