-/**
- * This aspect specifies debugging information to be output to the
- * information window.
- *
- * When the debug aspect is compiled in the Frame menu has several checkbox
- * items that can be used to control the amount of tracing information
- * displayed.  (By default the first three are off, because they generate
- * so much information.)
- *
- * There are two reasons to gather all this debugging code into an aspect
- * like this:
- *
- *   (1) It makes it easier to understand when it is all in one place.
- *
- *   (2) It means that we can "plug and debug".  We can enable/disable
- *       the debugging code simply by weaving or not weaving this
- *       aspect in.
- *
- * All in all, this is a lot better than the usual practice of writing
- * complex debugging code and then deleting it when the bug is found,
- * only to regret it a month later when a related bug surfaces.  (Or even
- * the same bug!)
- *
- * This file also defines a class InfoWin, which it uses to display all the
- * debugging information.
