This is great! Never knew there was something specific existing as command runner except for arcane or programming-lang specific tools (i.e. Rake, the Cargo one, etc). I have been abusing Makefiles as command runners for years now.
Yeah, Just is pretty awesome! Its biggest drawback over Make is that you can often assume Make is installed, whereas it's not always clear that Just needs to be installed if you've never heard of Justfiles before, let alone how to install it.
There are a few design decisions where I think Just missed an opportunity to improve on Make, but they're all pretty minor.
