# Note: this is a low level tool to be used only for tests
# It reads conditions from two CREST servers (or/and JSON files),
# compares values and dumps to the file difference, if it is above
# specified threshould

    description='Read conditions from CREST server (or/and JSON files), compare values and dump differences above specified thresholds',
    formatter_class=argparse.RawDescriptionHelpFormatter,
    epilog="""
Notes:
- Conditions are compared using logical AND: both maxdiff AND maxdiffpercent must be present (both have to be TRUE) to print
- If *2 parameters (run2, lumi2, folder2, tag2, schema2) are not given, values from primary parameters are used
- For single-version folders, use empty tag: --tag=""
 
Usage:
  # Compare CREST server vs JSON file
  python %(prog)s   --maxdiff=100 \\
                    --run=100012 \\
