Ok. Cool. That looks nice.

With that example, and unpatched nevow, I still get an error when
trying to browse to   http://localhost/images   (note, no trailing slash)
The error is the same as in my last post ...

File "/usr/local/lib/python2.3/site-packages/twisted/python/filepath.py", 
line 138, in open
    return open(self.path, mode+'b')
exceptions.IOError: [Errno 21] Is a directory

Also... trying to get the Nevow module from anonymous cvs is giving
me an error:

$cvs -d:pserver:anon at divmod.org:/cvs co Nevow
cvs server: cannot find module `Nevow' - ignored
cvs [checkout aborted]: cannot expand modules

Thank you for your time.
