-	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.

+    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.
