Turn up logging?

[roddy]

Is it possible to configure openapi3-generator to do more logging than simply printing out 'done!'?

I have a very large (but unfortunately proprietary) API spec that the generator is reporting as successfully having generated against, but the output directory is empty. Since the spec passes validation, I would like to try and figure out where the generator is going wrong but the only thing it's telling me is that my API has been successfully generated, and pointing to an empty folder.
