<h1>Welcome to Nevow</h1>
<p>This page contains examples of how to build web applications
on top of Nevow, in order of increasing complexity. To get a
feel of how to structure your Python code while using Nevow,
the source of all examples is linked for easy reference. In
order to run each example, you will need Zope Interface,
Twisted, and Nevow installed, and then you will need to run the
example server.</p>
<p>Under <strong>windows</strong>: you need to run the Twisted
Shell from Start-->Applications-->Twisted menu. Under a
unix like operating system, make sure that the twistd binary is
on your PATH. Installing Twisted will do this for you.</p>
<p>To run the example server, go to the Nevow examples
directory (eg: C:\Nevow\examples or /usr/src/Nevow/examples)
and run the following command:</p>
<blockquote>
twistd -noy examples.tac
</blockquote>
<p>Then, to view the running examples, point your web browser
at: <a class="linkification-ext" href=
"http://localhost:8080/">http://localhost:8080/</a></p>
<p>Once you are viewing this page as served by the example
server, all of the "live" links below will work.</p>
