Specify language when exporting Notebooks with nbdev

I couldn’t find any documentation about how to use nbdev to export a notebook written in a language different than Python, like Swift or Julia. Is this possible? Sorry if this is a repeated topic or if this question was answered somewhere else in the forum, I couldn’t find anything mentioning it.

Nbdev only supports python, and in exporting it does a lot of things that are python-ic (like creating __all__ or __init__).
Support for other languages will require a bit of work, so people interested should probably group together for this.
