Star PLZ on GitHub
We re-implemented PIP on ~500 lines of code, it deserves a Star ?.

What does this solve over
Poetry? (which is seeing a lot of adoption and is an experience similar toyarn, building on PEP517/518)Also, having everything in a single file does not make it desirable to use. It makes me think the author doesn't know how to make their code modular.
you don't really need to modularise if the whole app is 500 lines of code divided in 4 or 5 files. Poetry has hundreds of files with some of them even reaching more than 1000+ lines of code: should they modularise more instead ?
Looks amazing! Will try it at the first chance.
Does it aim to compete with Poetry, i.e. in the area of package management? Or is it purely a pip alternative?
