+ * parsing.</p>
+ *
+ * <p>Mainly useful when creating complex command based CLI interfaces,
+ * where several commands can share a set of arguments, but using
+ * object inheritance is not enough, due to no-multiple-inheritance
+ * restriction. Using {@link ParametersDelegate} any number of
+ * command sets can be shared by using composition pattern.</p>
+ *
+ * <p>Delegations can be chained (nested).</p>
