+/**
+ * Classes used to generate user interfaces using declarative ui.xml files.
+ * 
+ * <p>
+ * This package contains the classes and interfaces that allow you to define
+ * user interfaces from ui.xml template files, managed by generated
+ * implementations of the {@link UiBinder} interface. UiBinder templates allow
+ * you to lay out your widgets and design new ones via HTML, CSS and Image
+ * resources (the last two via generated {@link com.google.gwt.resources.client
+ * ClientBundles}) with a minimum of coding. They also have extensive support
+ * for internationalization, by generating
+ * {@link com.google.gwt.i18n.client.Messages Messages}.
+ * </p>
+ * 
+ * <p>
+ * Follow the links below for general documentation. Specialized markup for
+ * individual widget types is described in their javadoc. In particular, see
+ * {@link com.google.gwt.user.client.ui.UIObject UIObject} for markup that
+ * applies to all widgets.
+ * </p>
+ * 
+ * @see <a href="http://code.google.com/webtoolkit/doc/latest/DevGuideUiBinder.html">Declarative Layout with UiBinder</a>
+ * @see <a href="http://code.google.com/webtoolkit/doc/latest/DevGuideUiBinderI18n.html">Internationalization - UiBinder</A>
