+BlueJ example project "debugdemo"
+
+Copyright (c) Michael Kolling, Monash University, 1999-2000
+
+This project is distributed with the BlueJ system to provide an example
+for testing the debugger. The project does not make any sense at all. Its 
+purpose is to provide some loops and method calls to practice setting
+breakpoints and sigle-stepping through the code.
+
+This project is referred to in the BlueJ tutorial.
+
+To start this project, create a "Demo" object and select any of its methods.
