TADS 3 syntax highlter for gedit?

Does anyone know if there’s a TADS 3 syntax highlighter definition file available for gedit? I tried to look on the IF Archive – I thought there was a directory for syntax highlters somewhere on the Archive – but I couldn’t find anything.

I looked it up a couple of months ago and didn’t find anything. I ended up writing a very simple one on my own, which wasn’t too hard.
