[Zope] FileUpload get_size() method?

Hello, Does a FileUpload object have a get_size() method? I'd like to limit the size of an uploaded file before commiting it to the ZODB. I've been Googling for a while. Is it handled differently on a FileUpload object. I'm planning to process with a Python Script. Could someone point me in the right direction? Thanks In Advance, -Jon Cyr cyrj@cyr.info -- Jonathan Cyr cyrj@cyr.info
