splitting page into 2 columns?

[Fredrik Carlén]

Hello, me again! I am kinda new to this, so bear with me; I *will* RTFM (and to
some extent I have) thouroughly, but now all I have time for is to skim through
selected parts. In doing this, however, I have found no way of splitting the
page into two columns. My work in Lilypond right now is centered on printing one
single bar of 16th notes in 4/4, with repeat signs around them, and some
combination of R's and L's under them:
|: sn16_"R" sn16_"R" sn16_"R" sn16_"R" sn16_"R" sn16_"R" sn16_"R" sn16_"R"
sn16_"R" sn16_"R" sn16_"R" sn16_"R" sn16_"R" sn16_"L" sn16_"L" sn16_"R" :|

This isn't music, it's studying material for drummers :)

To print as many as possible of these, I need to split the page into two
columns. This is the last thing I need to do, everything else is working
perfectly. I haven't found anything in the manual, nor in LSR about how to do
this. Is it possible?

Best regards /Fredrik
