* @class Ext.layout.ContainerLayout
- * <p>The ContainerLayout class is the default layout manager delegated by {@link Ext.Container} to
- * render any child Components when no <tt>{@link Ext.Container#layout layout}</tt> is configured into
- * a {@link Ext.Container Container}. ContainerLayout provides the basic foundation for all other layout
- * classes in Ext. It simply renders all child Components into the Container, performing no sizing or
- * positioning services. To utilize a layout that provides sizing and positioning of child Components,
- * specify an appropriate <tt>{@link Ext.Container#layout layout}</tt>.</p>
* <p>This class is intended to be extended or created via the <tt><b>{@link Ext.Container#layout layout}</b></tt>
* configuration property. See <tt><b>{@link Ext.Container#layout}</b></tt> for additional details.</p>
