+A simple webapp to facilitate downloads for Facebook fans of a specific
+fan page. Supports open and S3 secured for downloads. 
+
+This requires a basic Facebook application to be created - the only real
+requirements are that you give it a name and point it to your domain. 
+More detailed instructions soon, but you can get started here:
+
+http://developers.facebook.com/get_started.php
+
+
+
+Built using the the connect-js (beta) library from Facebook:
+http://wiki.github.com/facebook/connect-js/faq
+
+and Jesse Stay's PHP client library reconfigured to work with connect-js:
