bbb.tex and then run it:

$ lualatex bbb

(babel)             There is nothing intrinsically wrong with it, but
(babel)             'babel' will no set Script and Language, which could
(babel)             be relevant in some languages. If your document uses
(babel)             these families, consider redefining them with \babelfont.
