+Disclaimer
+~~~~~~~~~~
+I don't care what you use this for. It's intended to be educational, and perhaps
+to the oddly minded - a little bit of fun. Please hack this, change it and use it
+in any way you see fit. BUT, you acknowledge that I am not responsible for anything
+bad that happens as a result of your actions. However, if good stuff happens, I
+would appreciate a shout out, or at least give the blog some publicity for me.
+Cheers!
+
+Background
+~~~~~~~~~~
+Often as an exercide, I'll try to right code where every byte of source code
+should count. I feel that this is an excellent way to practice logic, code
+comprehension and smarmy arrogance.
