[Zope] The zope way to do it

[Chris McDonough]

The Zope way to do this is no different, save for the fact that each
function that you want to call from Zope needs to be made into an
external method.

You make external methods by putting Python modules in the Extensions
directory of your Zope install and using the management interface to add
an External method.  You will need to name your external method.  This
name can be the same as the function name you're trying to call or it
could be something completely different, that's up to you.  Usually, I
like to name external methods beginning with an "em", so I'd probably
name my external method in this case "emDisplay."

The external method edit dialog will ask you for a function name and a
module name.  The function name is the name of the actual Python
function you'd like to call from Zope.  The module name is the module in
which the function lives.  In your example, you'd want to specify the
function as "display", loaded from module "test_aux".  Then in Zope,
you'd set up a DTML method or document (we'll call it dtDisplay) that
has this in it:

<dtml-var standard_html_header>
<h1>My Example Code</h1>
<dtml-var "emDisplay('This', 'is', 'a', 'very', 'simple', 'example')">
<dtml-var standard_html_footer>

So then when you call dtDisplay from the web, like:

http://mysite.com/dtDisplay

It should show:

My Example Code

This is a very simple example
