[racket] Adding a language to the Choose Language... menu

How can I add a new language or group of languages (similar to how the
teaching languages are presented) to the Choose Language... menu of
DrRacket?

I read through Adding Languages
<http://docs.racket-lang.org/tools/adding-languages.html?q=sgn#%28part._.Adding_.Arbitrary_.Languages_to_.Dr.Racket%29>
and
saw my question directly answered, but that was in the context of
'backwards compatibility', using an 'info.rkt' and drscheme definitions. I
don't want to use this if there is a preferred/updated method. I believe
the first section, #lang-based languages in Racket
<http://docs.racket-lang.org/tools/adding-languages.html?q=sgn#%28part.__lang-based_.Languages_in_.Dr.Racket%29>,
may address my question, but I didn't understand what it was telling me to
do.
