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.
