audible metronome in MIDI file?

I’d like to hear a metronome in the MIDI file generated by Lilypond. The best thing I can think of is to add a new voice that plays some high short note at the beginning of each beat. I’m hoping that there’s a better (easier?) way that I haven’t found. It’d be nice if I could just ask Lilypond

Thanks. That's what I was looking for. I hacked on it a bit.
