Twisted 10.2.0
Quote of the Release:
<glyph> khorn: "I know what you're thinking. 'Did he add six callbacks or
only five?' Well, to tell you the truth, in all this excitement, I
kind of lost track myself. But being as this is a Deferred, the most
powerful callback abstraction in the world, and would blow your head
clean off, you've got to ask yourself one question: do you know how
to add callbacks? well, do ya, punk?"

with the distribution.
What is this?
=============
Twisted is an event-based framework for internet applications. It includes
modules for many different purposes, including the following:
- twisted.application
A "Service" system that allows you to organize your application in
hierarchies with well-defined startup and dependency semantics,
- twisted.cred
A general credentials and authentication system that facilitates
pluggable authentication backends,
- twisted.enterprise
Asynchronous database access, compatible with any Python DBAPI2.0
modules,
- twisted.internet
Low-level asynchronous networking APIs that allow you to define
your own protocols that run over certain transports,
- twisted.manhole
A tool for remote debugging of your services which gives you a
Python interactive interpreter,
- twisted.protocols
Basic protocol implementations and helpers for your own protocol
implementations,
- twisted.python
A large set of utilities for Python tricks, reflection, text
processing, and anything else,
- twisted.spread
A secure, fast remote object system,
- twisted.trial
A unit testing framework that integrates well with Twisted-based code.
Twisted supports integration of the Win32, Tk, GTK+ and GTK+ 2 event loops
with its main event loop. There is experimental support for Mac OS X and
wxPython event loop integration, which you use at your peril.

There are many official Twisted subprojects, including clients and
servers for web, mail, DNS, and more. You can find out more about
these projects at http://twistedmatrix.com/trac/wiki/TwistedProjects
Installing
==========
Instructions for installing this software are in INSTALL.
Unit Tests
==========
See our unit tests run proving that the software is BugFree(TM):
% trial twisted
Some of these tests may fail if you
* don't have the dependancies required for a particular subsystem installed,
* have a firewall blocking some ports (or things like Multicast, which Linux
NAT has shown itself to do), or
* run them as root.
Documentation and Support
=========================
Examples on how to use Twisted APIs are located in doc/core/examples; this
might ease the learning curve a little bit, since all these files are kept
as short as possible. The file doc/core/howto/index.xhtml contains an index
of all the core HOWTOs: this should be your starting point when looking for
documentation.
Help is available on the Twisted mailing list:
http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
There is also a very lively IRC channel, #twisted, on
chat.freenode.net.
