5 <glyph> khorn: "I know what you're thinking. 'Did he add six callbacks or
6 only five?' Well, to tell you the truth, in all this excitement, I
7 kind of lost track myself. But being as this is a Deferred, the most
8 powerful callback abstraction in the world, and would blow your head
9 clean off, you've got to ask yourself one question: do you know how
10 to add callbacks? well, do ya, punk?"
13 For information on what's new in Twisted 10.2.0, see the NEWS file that comes
14 with the distribution.
19 Twisted is an event-based framework for internet applications. It includes
20 modules for many different purposes, including the following:
23 A "Service" system that allows you to organize your application in
24 hierarchies with well-defined startup and dependency semantics,
26 A general credentials and authentication system that facilitates
27 pluggable authentication backends,
29 Asynchronous database access, compatible with any Python DBAPI2.0
32 Low-level asynchronous networking APIs that allow you to define
33 your own protocols that run over certain transports,
35 A tool for remote debugging of your services which gives you a
36 Python interactive interpreter,
38 Basic protocol implementations and helpers for your own protocol
41 A large set of utilities for Python tricks, reflection, text
42 processing, and anything else,
44 A secure, fast remote object system,
46 A unit testing framework that integrates well with Twisted-based code.
48 Twisted supports integration of the Win32, Tk, GTK+ and GTK+ 2 event loops
49 with its main event loop. There is experimental support for Mac OS X and
50 wxPython event loop integration, which you use at your peril.

55 There are many official Twisted subprojects, including clients and
56 servers for web, mail, DNS, and more. You can find out more about
57 these projects at http://twistedmatrix.com/trac/wiki/TwistedProjects
63 Instructions for installing this software are in INSTALL.
69 See our unit tests run proving that the software is BugFree(TM):
73 Some of these tests may fail if you
74 * don't have the dependancies required for a particular subsystem installed,
75 * have a firewall blocking some ports (or things like Multicast, which Linux
76 NAT has shown itself to do), or

81 =========================
83 Examples on how to use Twisted APIs are located in doc/core/examples; this
84 might ease the learning curve a little bit, since all these files are kept
85 as short as possible. The file doc/core/howto/index.xhtml contains an index
86 of all the core HOWTOs: this should be your starting point when looking for
