Similar to a PKGBUILD file for Arch. It is 2020 and like WSL, it will probably take at least 2 iterations and 3 more years before this half-works and honestly as much as I want this to be successful they will have to create an entirely different package format for it to. Like EXE installers are so unpredictable already and Chocolatey does okay but packages frequently get broken and many of them are unmaintained.
