Usage: $0 [-strict] PREVIOUS CURRENT

Compare the PREVIOUS and CURRENT test case .sum files, reporting anything of interest.

	If PREVIOUS and CURRENT are directories, find and compare any *.sum files.

	Unless -strict is given, these discrepancies are not counted as errors:
		missing/extra .sum files when comparing directories
		tests that failed in PREVIOUS but pass in CURRENT
		tests that were not in PREVIOUS but appear in CURRENT
		tests in PREVIOUS that are missing in CURRENT

	Exit with the following values:
		0 if there is nothing of interest
		1 if there are errors when comparing single test case files
		N for the number of errors found when comparing directories
