The primary purpose of this program is to demonstrate
pluggable look and feel (PL&F) and the ability to change
the L&F at runtime.

It also illustrates a couple of requirements of using
Swing components that differ from using AWT components.

The program creates a GUI in a JFrame containing a 
PlafPanel.  The PlafPanel01 is instantiated from a custom 
class named PlafPanel01 and contains one JButton for each 
L&F implementation in the currently installed JDK.  

The name of the L&F is displayed on each JButton on the
PlafPanel01.

The PlafPanel01 is added to the content pane of the JFrame.
Clicking each JButton on the PlafPanel01 will cause the L&F
of the GUI to change to the L&F represented by that 
JButton.

The program also creates another GUI in a JFrame which is
intended to simulate a GUI under test.  This GUI contains
an inactive JButton and an inactive JTextField.  These
components are provided so that you can see how then behave
when the L&F is changed.

It is instructive to see how shapes and colors for these
inactive components change as each different L&F is 
implemented.
 
Tested using JDK 1.1.3 and Swing 1.0.1 under Windows 95
