[Zope] copying folder?

Is there a way to copy a folder on zope, nightly through a cron job and then rename it? I would think I could call lynx or wget from cron with a zope url but I don't know how I would go about doing it. Example of what I want to do: I have a folder in the root of zope called py_scripts I want to copy. Then I want to rename the copied folder py_scripts with today's date on the end of it. I would like cron to do this nightly for me. Any ideas? Thanks, Greg
