Swung quaver notation

[Philip Potter]

Dear all,

I'd like to get a direction for swung quavers at the top of my score.
What I want is:

quaver-beam-quaver = triplet[ crotchet quaver ]

if that makes sense. I've had a look through the lilypond-user
archives and it seems it wasn't possible 5 years ago:
http://lists.gnu.org/archive/html/lilypond-user/2004-02/msg00273.html

have things changed at all since then or am I stuck with no beam
between the quavers?

Thanks,

Philip
