Interestingly, this package manager is based off of the Futhark package manager (https://futhark-lang.org/blog/2018-08-03-the-present-futhark...), which has a very simple, yet powerful design. It's basically language agnostic, which means the technique could easily be used for other languages as well.
Edit: It's also about time that SML got a proper package manager. Smackage never really worked well.
