 Just is a great task runner, but it suffers two problems, users probably don't have it installed already, and there is no way to define file specific recipes.
 Most of my `Makefile`'s are comprised primarily of handy `.PHONY` recipes, but I always end up with a few file specific recipes.

 Another interesting project I've evaluated for these purposes is [`go-task/task`](https://github.com/go-task/task).
 `Task` has many of the features of `GNU Make` and some novel features of it's own.
 But like `just` it's a tool people don't usually already have and it's configured using a `yaml` file.
-`Yaml` files can be finicky to work with and and it uses a golang based shell runtime not your native shell, which might lead to unexpected behavior.
