# Usage: gnustep-tests [directory | test.m]
#
# Runs the tests in the specified directory (or those in the individual file)
# or all the tests in subdirectories of the current directory if no arguments
# are given.
# A summary is written to tests.sum, a log to tests.log, and a brief
# summary to stdout.
# The log and summary from the previous testrun are renamed to
# oldtests.log and oldtests.sum, available for comparison.
