If I remember correctly, Han-Wen wrote it and I paid him a bounty for it…  =)

Yes, of course, that's what I've been doing — but I consider it hacky, so I was 
hoping someone had a more elegant solution.

I've been using it for 10 years now.

This piece ("Robin Hood: The Legendary Musical Comedy") is simply taxing 
Lilypond's abilities more than other works I've engraved in the past: 2.5 hours 
of music theatre for 8 instruments (including 2 multi-instrumentalists), 9 
vocal soloists, and a chorus of up to three independent two-part lines.

Thanks!
Kieren.
