+% This version is being checked in for the historical record; it shows
+% how I've managed to get some aspects of this to work. It will not
+% be used in practice, so a subsequent revision will change things
+% again. This version has problems, but shows how to do something
+% that proved more tedious than I'd expected, so I don't want to lose
+% the example completely.
