14 | * This is exported because even though the Python plugin provider is a | |

19 | * The default log level is NONE: we don't print logging statements for | |
20 | * any executable which links with the library. The executable must call | |
21 | * bt_logging_set_global_level() or the executable's user must set the | |
22 | * `LIBBABELTRACE2_INIT_LOG_LEVEL` environment variable to enable | |
23 | * logging. | |
