public abstract class Application

extends javax.swing.JPanel

This class is meant to provide access from all packages to certain general-purpose items of the application, such as the UserProperties objects that the application uses, and the JFrame that the application is in. It allows classes from all packages to show help topics. However, getting the actual topics themselves is the responsibility of a class which subclasses Application.
