Uv packager test

There's a new (yet another) package manager for python, uv. https://docs.astral.sh/uv/

It is close to pip but has some nice features.

For example "on-the-fly" environments that are fast.

Could be good for examples etc.

cd examples

uv run jupyter lab

And then one is up and running..

examples/pyproject.toml
