+  <h2>Adding Custom Classes to the nibfile</h2>

+
+<p>The user interface for your application looks right, but before it
+  can work right, we have to record some more information  in the
+  nibfile about the classes of the objects. In the following sections
+  we'll see how to write the Lisp code that defines your
+  application's classes. Before we're done with InteraceBuilder we
+  need to put references to those classes in the nibfile, so that
+  your application will create the correct objects when it
+  launches.</p>
+
+<p>As you will see in the following sections, we'll be using Lisp code
+  to define two Objective C classes: Converter, and
+  ConverterController. The Converter class implements the method that
+  performs the actual currency conversion for our application; the
+  ConverterController class provides communication between the user
+  interface and the Converter object. We need a way to create instaces
+  of these two classes in the nibfile, so that launching the
+  application creates these instances and the connections between them
+  and the rest of the user interface.</p>
+
+<p>In InterfaceBuilder's Library window, select the Cocoa Objects and
+  Controllers view:</p>

+
+<p>Drag an Object from the Library window and drop it into the main
+  CurrencyConverter window:</p>

+      <div class="inline-image">
+        <img src="../images/ibwin-leopard4.jpg"alt="" 
+             border='0'/>
+      </div>
+
+<p>Now tell InterfaceBuilder the name of the new object's class. With
+  the Object icon selected in the main CurrencyConverter window,
+  choose the Identity tab of the Inspector:</p>
