+%D Columns are kind of hairy in \TEX\ and we would be better if no one needed them.
+%D Anyway, we do need some support and no mechanism can serve all. The original
+%D multicolumn mechanism of \MKII\ was never fully adapted to \MKIV, where mixed
+%D columns and page columns showed up instead. However, for some cases a dumb
+%D mechanism makes sense, so again we introduce multi columns, but without float
+%D hacks. This one will be optimized for mixed usage as for instance itemize needs.
+%D Their main advantage is that they can better deal with notes, which are hairy in
+%D themselves. This will (for now) only happen in \LMTX.
+%D
+%D The code is stripped down ancient \MKII\ code and might become cleaner as it
+%D evolves. Macros keep similar names but take a different namespace. The code is
+%D not yet perfect wrt spacing!
