+	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.
