[Zope] How do I get DocumentTemplate to work?

Sat Aug 16 06:42:22 EDT 2003

I'm trying to switch over to python from DTML......
I've got a python Script (to see what DocumentTemplate does) that looks
like the following:

from DocumentTemplate import HTML
template_source = """
<html>
  <head>
    <title> <dtml-var title_or_id></title>
  </head>
  <body>
  <dtml-var content>
</body>
</html>
"""
template_method = HTML(template_source)
results = template_method(title="ThisDocument!",
                          content="This is cool!!!!" )

But, when I try to run it, I get:
Error Type: ImportError
Error Value: import of "HTMLFile" from "DocumentTemplate" is
unauthorized. You are not allowed to access HTMLFile in this context

What is it I'm doing wrong?

TIA,
