//
// Author: Jason Levitt
// Date: December 7th, 2005
//
// A SECURITY WARNING FROM DOUGLAS CROCKFORD:
// "The dynamic <script> tag hack suffers from a problem. It allows a page
// to access data from any server in the web, which is really useful.
// Unfortunately, the data is returned in the form of a script. That script
// can deliver the data, but it runs with the same authority as scripts on
// the base page, so it is able to steal cookies or misuse the authorization
// of the user with the server. A rogue script can do destructive things to
// the relationship between the user and the base server."
//
// So, be extremely cautious in your use of this script.
