Dear Jeff Anderson,
Thank you for your email.
It sounds very interesting to me. I must confess that I am not a
programmer, and have no experience with Django. But I have a project
in hand to do such a work.
Have you ever tried to use feedback.py to fire off another Python
script (external script)? The external script may run for 2 - 3
minutes.
Perhaps you can show me how to use feedback.py to fire off a zip.py.
Your assistance will be deeply appreciated.
Sincerely,
David
