I'd love to write a script that could be integrated into Davos as a CLI entrypoint, and provide a tool that people could use to "davos-enhance" a notebook automatically.

The use case I'm imagining is you have a Jupyter notebook you want to share with someone, and you want to turn it into a "davos-enhanced notebook" to more easily share it in a reproducible way. So you open a terminal and run davos enhance path/to/notebook.ipynb. The script then:

• adds a new cell at the top of the notebook that %pip installs and imports davos
• parses the code in the notebook and replaces all import statements with equivalent smuggle statements
• adds onion comments next to each smuggle statement that specify the package versions installed in your environment

The davos enhance command could support various options to do things like:

• add a davos.require_python() call before the first smuggle statement
• not add onion comments for certain (or any) packages
• create a copy of the notebook rather than modifying the original
• enable or set various davos.<foo> options before smuggling packages

Seems like a great idea! (But for a future release)
