-Flaschengeist provides a CLI, based on the flask CLI, respectivly called `flaschengeist`.
-
-⚠️ When using the CLI for running Flaschengeist, please note that logging will happen as configured,
-with the difference of the main logger will be forced to output to `stderr` and the logging level
-of the CLI will override the logging level you have configured for the main logger.
