Re: Make an ordered list of sdists to be installed?

I don’t know the details, but I did read that Poetry has a sophisticated
dependency resolver.

https://github.com/sdispater/poetry

I don’t know if there is a way to access the resolver independently of the
tool, but perhaps it would provide a handy reference.
