Thanks Wichert, I've hit some problems here, and muddled along a bit, if
you ( or someone ) can check this that would be great.

I assume I'm also supposed to add??

I copied the above in, and imported render_pt from lib/pt.py, but when I
try to render a template like so:
(in a controller)
def zpt(self):
"test of using zpt templates"
return render_pt("mytemplate.pt")
I get the following traceback, any help much appreciated.
