`just` is a handy way to save and run project-specific commands.
Commands are stored in a file called `justfile` or `Justfile` with syntax inspired by `make`:
```make
build:
cc *.c -o main
# test everything
test-all: build
./test --all
# run a specific test
test TEST: build
./test --test {{TEST}}
```
`just` produces detailed error messages and avoids `make`'s idiosyncrasies, so debugging a justfile is easier and less surprising than debugging a makefile.
It works on Linux, MacOS, and Windows.
