+ *
+ * This example showcases the uses of tty through stdio facilities. If you've
+ * written text console applications before, this one is not too dissimilar to
+ * that. Escape codes for formatting and such should work as this is more 
+ * dependant on the terminal program used than the PS1 console itself.
