+/**

+* Buttons can be configured, and to some degree controlled, by

+* <code>Action</code> with a button has many benefits beyond directly
+* configuring a button.  Refer to <a href="Action.html#buttonActions">
+* Swing Components Supporting <code>Action</code></a> for more
+* details, and you can find more information in <a
+* href="http://docs.oracle.com/javase/tutorial/uiswing/misc/action.html">How
+* to Use Actions</a>, a section in <em>The Java Tutorial</em>.
+* <p>
+* For further information see
+* <a
+href="http://docs.oracle.com/javase/tutorial/uiswing/components/button.html">How to Use Buttons, Check Boxes, and Radio Buttons</a>,
+* a section in <em>The Java Tutorial</em>.
+* <p>
+* <strong>Warning:</strong>
+* Serialized objects of this class will not be compatible with
+* future Swing releases. The current serialization support is
+* appropriate for short term storage or RMI between applications running
+* the same version of Swing.  As of 1.4, support for long term storage
+* of all JavaBeans&trade;
+* has been added to the <code>java.beans</code> package.
