Swing notation in LilyPond?

[Carl Peterson]

I've been trying to figure out how to do two things related to Jazz and
swing in LilyPond.

1) How do I do the normal swing indication (2 eighth notes = triplet
quarter and eighth)?

2) Is there a tweak to get eighth notes to line up like triplets per a
swing rhythm? That is, without explicitly specifying that the notes are
triplet, get the first eighth note to line up normally but the second in a
pair to line up with the third triplet eighth? I don't require that it work
with MIDI, just so that the notation looks parallel.

The first is more important to me than the second. Any help on this would
be appreciated.
