Multi column page setup

[Hanns Holger Rutz]

hello,

how can I set up lilypond to use a multiple column page layout. I have very 
short independent scores, and I would like to arrange them in four example four 
columns next to each other. It doesn't matter whether the grid goes 
left-to-right then top-to-bottom or the other way round.

thanks, ..h.h..
