-    Like writeScript but the first line is a shebang to babashka

-    Can be called with or without extra arguments.
+    `pkgs.babashka-unwrapped` is used as default interpreter for small closure size. If dependencies needed, use `pkgs.babashka` instead. Pass empty string to check to disable the default clj-kondo linting.
