What is Twisted?

Twisted is an event-driven framework for building networked clients and
servers.  It contains a powerful and simple networking core, a
full-featured suite of interoperable protocols, among them a powerful
web server and applications framework.

Twisted supports many event loops for both server apps and GUI
integration on the client side, including:

 - Win32 events, including GUI support
 - Mac OS X
 - GTK+
 - GTK+ 2
 - Qt
 - wxPython
 - Tkinter

Twisted can run protocols over TCP, SSL, UDP, multicast, Unix sockets
and subprocesses. It also includes scheduling support, threading
integration, RDBMS event loop integration and other basic requirements
for networked applications.

Also included are implementations of many protocols. In some cases this
includes complete frameworks providing facilities on top of the base

 - SSH
 - DNS
 - FTP (client only, server needs rewrite)
 - HTTP, including a complete web framework
 - Jabber
 - SIP
 - XML-RPC server and client frameworks
 - SOAP server framework
 - NNTP and complete NNTP server framework
 - SOCKSv4 (server only)
 - IRC
 - telnet
 - POP3
 - AOL's instant messaging TOC
 - MSN messaging
 - OSCAR, used by AOL IM as well as ICQ (client only)
 - MouseMan serial mice, and GPS devices
 - Twisted Perspective Broker, a remote object protocol
