+ *
+ * Rather than recreating the user interface manually in code the tool nib2obj

+ * names. Which means here is a lot of garbage you would never write in real
+ * life. Please ignore the following "wall of code" for the purposes of
+ * learning Nimrod, this is all just because Apple can't be bothered to
