  19                 missing/extra .sum files when comparing directories
  20                 tests that failed in PREVIOUS but pass in CURRENT
  21                 tests that were not in PREVIOUS but appear in CURRENT
  22                 tests in PREVIOUS that are missing in CURRENT

  24         Exit with the following values:
  25                 0 if there is nothing of interest
  26                 1 if there are errors when comparing single test case files
  27                 N for the number of errors found when comparing directories
