-          Input agat config file. By default AGAT takes as input agat_config.yaml file from the working directory if any, otherwise it takes the original agat_config.yaml shipped with AGAT. To get the agat_config.yaml locally type: `agat config --expose`. The `--config` option gives you the possibility to use your own AGAT config file (located elsewhere or named differently).
