-    Usage Note:  
-    -----------
-    Do not use both ajaxSubmit and ajaxForm on the same form.  These
-    functions are intended to be exclusive.  Use ajaxSubmit if you want
-    to bind your own submit handler to the form.  For example,
-
-    $(document).ready(function() {
-        $('#myForm').bind('submit', function() {
-            $(this).ajaxSubmit({
-                target: '#output'
-            });
-            return false; // <-- important!
-        });
-    });
-
-    Use ajaxForm when you want the plugin to manage all the event binding
-    for you.  For example,
-
-    $(document).ready(function() {
-        $('#myForm').ajaxForm({
-            target: '#output'
-        });
-    });
-        
-    When using ajaxForm, the ajaxSubmit function will be invoked for you
-    at the appropriate time.
