+  Update: 21-06-2010
+  The basic authentication service for twitter is going down at the end of the week.
+  To continue using that program, the code has been updated to use http://supertweet.net which acts as an API proxy.
+  Simply visit the website to setup your twitter account for this API.
+  See: http://www.supertweet.net/about/documentation
