+# Implementation of the bgerror procedure. It posts a dialog box with
+# the error message and gives the user a chance to see a more detailed
+# stack trace, and possible do something more interesting with that
+# trace (like save it to a log). This is adapted from work done by
+# Donal K. Fellows.
