+BlueJ example project "people"
+
+Copyright (c) Michael K<>lling, Monash University, 1999-2000
+
+This is a very simple BlueJ demo project. It illustrates some aspects of
+object-orientation as well as aspects of BlueJ.
+
+This project is distributed with the BlueJ system to serve as an introductory
+practice example. It is referred to in the BlueJ tutorial. Please read the
+tutorial (which you can get by selecting "BlueJ Tutorial..." from the Help
+menu ion the BlueJ main window) for more detailed information.
+
+You can use this project as follows:
+
+ - create a few Staff or Student obejcts
+ - create a Database object
+ - use "addPerson" in Database to add the persons you have created previously
+   from the object bench to the database
+ - use the "listAll" from the database object to list the contents of the 
+   database.
+
+This project illustrates:
+
+ - object creation
+ - relationship class-object (create _more then one_ object!)
+ - instance data (use "Inspect" on the objects)
+ - methods, parameters
+ - composition
+ - ...
