see [[manual:columns.pdf|Columns manual]] or [[source:page-set.tex|column sets source]]
If you don't need much more than the "normal" columns, but e.g. "lines" mode, try this:
<texcode>
\definecolumnset[twocol][n=2]
\startcolumnset[twocol]
\startlines
Starlight, star bright,
first star I see tonight;
\stoplines
\column % here it works!
\startlines
I wish I may, I wish I might
have the wish I wish tonight.
\stoplines
\stopcolumnset
</texcode>
If you need more (layout grid features, spreads, different column widths etc.) please read the manual!
