+By default, analysis results are printed to stdout in JSON format. When using the `--output` option, results are saved to `analysis.json` in the specified directory. If you use the `--format=msgpack` option, the results will be saved in `analysis.msgpack`, which is a binary format that can be more efficient for storage and transmission.
