The CLI doesn't have a --debug (or similar) option that can enable debugging output. It is possible to set DEBUG=true envvar, but that is not documented anywhere.

Enabling a debug output just for a single command execution is very useful when trying to get detailed logs of some action without the need to alter global configuration.

Implement a general --debug cli option (or similar) and optionally document the alternative route of setting an envvar, if it fits somewhere.
