+%D We have been using the units module (and its predecessor) for over a decade
+%D now but when we moved on to \LUATEX\ a variant was prototyped that permits a
+%D less texie coding. I finally picked up that thread and cleaned up the code a
+%D bit so users can now play with it. (The main reason was that I wanted to
+%D test exporting.)
