R: [Zope] upload file from filename

Hi, If the problem is upload from client without browser, for multiple uploads with one click, I uploaded a file to my Zope Server with cUrl (http://curl.haxx.se/) command line, so I think possible use it in a Python script. (I'm not a Python expert so this is only my idea: it is so wrong? I also tried with standard Python libraries and http://curl.haxx.se/rfc/rfc2388.txt without success :(). Thanks Michele
