One of the reasons I know I still rely on Make instead of Just, is about how available make is, and pretty much any tool (be it a new implementation of make in Rust or Just) will have to deal with the fact that make is already a default on so many systems.

That makes make a great entry point for any project. Does anyone have a general suggestion about how to work around this? The goal being, sync a project and not need to install anything to get going. One thing I do sometimes is to use make as the entry point, and it has an init target to install the necessary tools to get going (depends on who I know to be the target audience).
