<h2>Introduction<a name="auto0"/></h2>
17
Twisted is a big system. People are often daunted when they approach it. It's
18
hard to know where to start looking.
22
This guide builds a full-fledged Twisted application from the ground up, using
23
most of the important bits of the framework. There is a lot of code, but don't
28
The application we are looking at is a <q>finger</q> service, along the
29
lines of the familiar service traditionally provided by UNIX™ servers.
30
We will extend this service slightly beyond the standard, in order to
31
demonstrate some of Twisted's higher-level features.
35
Each section of the tutorial dives straight into applications for various
36
Twisted topics. These topics have their own introductory howtos listed in
37
the <a href="../index.html" shape="rect">core howto index</a> and in the documentation for
38
other Twisted projects like Twisted Web and Twisted Words. There are at least
39
three ways to use this tutorial: you may find it useful to read through the rest
40
of the topics listed in the <a href="../index.html" shape="rect">core howto index</a> before
41
working through the finger tutorial, work through the finger tutorial and then
42
go back and hit the introductory material that is relevant to the Twisted
43
project you're working on, or read the introductory material one piece at a time
44
as it comes up in the finger tutorial.
