  *
- * Plugins are injected 
+ * <p>The AbstractPlugin class is the base class from which user-implemented plugins should inherit.</p>
+ * <p>This class defines the essential API of plugins as used by Components by defining the following methods:</p>
+ * <ul>
+ * <li><code>init</code> : The plugin initialization method which the owning Component calls at Component initialization
+ * time.<div class="sub-desc"><p>The Component passes itself as the sole parameter.</p><p>Subclasses should set up bidirectional
+ * links between the plugin and its client Component here.</p></div></li>
+ * <li><code>destroy</code> : The plugin cleanup method which the owning Component calls at Component destruction time.<div class="sub-desc">Use
+ * this method to break links between the plugin and the Component and to free any allocated resources.</div></li>
+ * <li><code>enable</code> : The base implementation just sets the plugin's <code>disabled</code> flag to <code>false</code><div class="sub-desc"></div></li>
+ * <li><code>disable</code> : The base implementation just sets the plugin's <code>disabled</code> flag to <code>true</code><div class="sub-desc"></div></li>
+ * </ul>
