scripted web ui testing?

Greetings,

For a web application that is unrelated to zope, I need to do some scripted 
actions through the web interface.  Ideally I want to use python.  I'm 
wonding if any of you out there have using any web ui testing toolkits for 
python that are out there?  Any recommendations?  I seem to recall this being 
mentioned before, but I can't recall...

What I need is a simple package that will allow me to login to a web 
application (posting a form), keep cookie state, and can do repeated form 
submissions while logged in.

I'm looking at twill right now, and it seems like it'll do the job.  But, I'm 
wondering what the rest of you think.

Thanks for the input,
Andy
