+%D This is very experimental code! We took a bit from the mixed columns and single
+%D column page code. This one works acceptable with floats and is for whole double
+%D column documents. We don't balance (yet). Footnotes are per column. One can have
+%D side floats too. No balancing and other fancy features.
+%D
+%D Don't use this in production! Although the main approach will stay there might be
+%D changes in th ewya floats are dealt with. Not much testing has been done but as
+%D we stay close to the single column mode we expect most to just work. Only floats
+%D are the (usual) pain. Backgrounds, line numbering, etc.\ not tested either.
