Besides Cargo, you might want to take a look at Python's pyproject.toml standard. https://packaging.python.org/en/latest/guides/writing-pyproj...

It's similar, but designed for an existing ecosystem. Cargo is designed for `cargo`, obviously.

But `pyproject.toml` is designed for the existing tools to all eventually adopt. (As well as new tools, of course.)
