 /**
  * 
- * Chain of Responsibility organizes request handlers ({@link RequestHandler}) into a
- * chain where each handler has a chance to act on the request on its turn. In
- * this example the king ({@link OrcKing}) makes requests and the military orcs
- * ({@link OrcCommander}, {@link OrcOfficer}, {@link OrcSoldier}) form the handler chain.
+ * The Chain of Responsibility pattern is a design pattern consisting of command 
+ * objects and a series of processing objects. Each processing object contains 
+ * logic that defines the types of command objects that it can handle; the rest are 
+ * passed to the next processing object in the chain. A mechanism also exists for 
+ * adding new processing objects to the end of this chain.
+ * <p>
+ * In this example we organize the request handlers ({@link RequestHandler}) into a
+ * chain where each handler has a chance to act on the request on its turn. Here
+ * the king ({@link OrcKing}) makes requests and the military orcs ({@link OrcCommander}, 
+ * {@link OrcOfficer}, {@link OrcSoldier}) form the handler chain.
