Is there a way to split a score across two sheets?

[Ben Beeson]

Hi,

I use LilyPond for bagpipe music.  I find LilyPond and the included
bagpipe.ly file to work very well for that task.  Thanks!

I looked in the documents and in other places online for help and did
not find anything on how to split a score across two sheets, so Iam
hoping the list can provide some insight. What I am looking to do is to
easily split a score across two sheets much like you can make a score
use two pages instead of one with a \pageBreak at the appropriate place.
For example, the tune Cabar Feidh is much easier to read from a single
sheet if printed landscape as opposed to printing portrait. This is just
because some of the bars are "more busy" with doublings and throws etc.
than others making certain parts a bit crowded when printing this tune
in portrait orientation.  I realize I could create two separate scores,
one for each sheet, but that becomes cumbersome if you ever decide to
display the tune differently.  

So I was wondering if there was an easy way to split a score across two
sheets when printing so the tune essentially puts the first two bars on
the left sheet and the last two bars of each line on the right sheet of
an open book?

Thanks in advance,

Ben
