+%D This module is the result of a discussion between Alan Braslau and
+%D me. I used to have a private (\MKII) module for this but the new
+%D structure code in \MKIV\ is more suitable for this so now we have
+%D it as core functionality. For the moment this an experiment that
+%D Alan and I conduct so it might evolve.
