Also note that your Genshi templates (views) must be valid XML.  If they aren't Genshi will raise an exception.

There's a URL in the PDF of Genshi's Documentation website.  It's ok, but could use some attention.  Feel free to ask me questions.

The article in Alter-Ego shows how to setup your controller to default to Genshi templates.  But if it fails, it will fall-back to normal web2py templates.

Basically your init/controllers/default.py controller should look like this:
response.postprocessing.append(lambda x: Genshi4web2py.render(x, request, response))

def index():
    numbers = range(0,10)
    return dict(text="Welcome to Genshi4web2py", nums = numbers)
The corresponding view (init/views/default/index.html) could look like:

<html xmlns:py="http://genshi.edgewall.org/" xmlns="http://www.w3.org/1999/xhtml" xmlns:xi="http://www.w3.org/2001/XInclude">
<head>
  <title>Genshi4web2py Demo</title>
</head>
<body>
  <h1>${text}</h1>
  <ol>
    <li py:for="">This is number ${n}<li>
  </ol>
</body>
</html>

As far as making Genshi templates, see the attached cheatsheet.  I made this for my co-worker.  It should give you a basic primer.  Before you use XInclude too much, note that Genshi makes full use of XSLT and you can use one included template to completely transform another.  I use this method for including my default header but it is not necessary by any means.  If the XSLT part confuses you, ignore it, you don't need it to understand use Genshi.

Does that help?

What is the best link for a quick intro of how to use genshi templates
with web2py?  I don't mean install/configure but examples of actual
controllers/templates/outputs.

Massimo has posted a more recent Genshi4web2py.py module in AlterEgo for me.  If you use (want to use) Genshi with web2py, you can get it from:http://mdp.cti.depaul.edu/AlterEgo/default/show/162
This new version adds cache support (for a large speed boost) and full Genshi rendering options in a configurable manner.  It should be backward compatible with the old version.
