scalable, non-blocking web server and tools - Python 3 package

 Tornado is a Python web framework and asynchronous networking library,
 originally developed at FriendFeed. By using non-blocking network I/O,
 Tornado can scale to tens of thousands of open connections, making it ideal
 for long polling, WebSockets, and other applications that require a
 long-lived connection to each user.

 This is the Python 3 version of the package.
