+/**
+ * The interface for a custom tag used by Doclets. A custom
+ * tag must implement this interface.  To be loaded and used by
+ * doclets at run-time, the taglet must have a static method called
+ * <code>register</code> that accepts a {@link java.util.Map} as an
+ * argument with the following signature:
+ * <pre>
+ *   public void register(Map map)
+ * </pre>
+ * This method should add an instance of the custom taglet to the map
+ * with the name of the taglet as the key.  If overriding a taglet,
+ * to avoid a name conflict, the overridden taglet must be deleted from
+ * the map before an instance of the new taglet is added to the map.
+ * <p>
+ * It is recommended that the taglet throw an exception when it fails
+ * to register itself.  The exception that it throws is up to the user.
+ * <p>
+ * Here are two sample taglets: <br>
+ * <ul>
+ *  <li><a href="{@docRoot}/../../../../technotes/guides/javadoc/taglet/ToDoTaglet.java">ToDoTaglet.java</a>
+ *         - Standalone taglet</li>
+ *  <li><a href="{@docRoot}/../../../../technotes/guides/javadoc/taglet/UnderlineTaglet.java">UnderlineTaglet.java</a>
+ *         - Inline taglet</li>
+ * </ul>
+ * <p>
+ * For more information on how to create your own Taglets, please see the
+ * <a href="{@docRoot}/../../../../technotes/guides/javadoc/taglet/overview.html">Taglet Overview</a>.
