NAME

       Jifty::Web::Form::Field::Upload - File upload field

DESCRIPTION

       An input field that renders using "<input type="file" />".  The argument value that the
       action receives from this field via "argument_value" in Jifty::Action will be a
       filehandle, which can be read in the usual ways.

   render_widget
       Renders the file upload widget.

   render_value
       The 'value', rendered, is empty so that BLOBs and the like don't get streamed to the
       browser.

   classes
       Add 'upload' to the rest of the classes
