+/**
+ * Interface describing an object capable of rendering a border
+ * around the edges of a swing component.
+ * For examples of using borders see
+ * <a href="http://java.sun.com/docs/books/tutorial/uiswing/misc/border.html">How to Use Borders</a>,
+ * a section in <em>The Java Tutorial.</em>
+ * <p>
+ * In the Swing component set, borders supercede Insets as the
+ * mechanism for creating a (decorated or plain) area around the
+ * edge of a component.
+ * <p>
+ * Usage Notes:
+ * <ul>
+ * <li>Use EmptyBorder to create a plain border (this mechanism
+ *     replaces its predecessor, <code>setInsets</code>).
+ * <li>Use CompoundBorder to nest multiple border objects, creating
+ *     a single, combined border.
+ * <li>Border instances are designed to be shared. Rather than creating
+ *     a new border object using one of border classes, use the
+ *     BorderFactory methods, which produces a shared instance of the
+ *     common border types.
+ * <li>Additional border styles include BevelBorder, SoftBevelBorder,
+ *     EtchedBorder, LineBorder, TitledBorder, and MatteBorder.
+ * <li>To create a new border class, subclass AbstractBorder.
+ * </ul>
