[Zope] Any examples of use of manage_addFile()?

[complaw@hal-pc.org]

I want to create a user-interface so that users can upload files to my Zope
site.  I have done this with DTMLDocuments, however I don't quite understand how
to get the file itself into the Zope site via ...

self.manage_addProduct['OFSP'].manage_addFile()

..that is in Python.

I looked through the HOWTO's but didn't find anything.  Does someone have an
example of a Form/DTMLMethod/Python script that does this sort of thing?

Thanks in advance,

Ron
