[reportlab-users] ReportLab and Django Examples

[Mike Hostetler]

Just to help you out - page 7 of the User Guide also needs to be updated:

   outputFileNamewhen specified overrides any output file name specified in
   the xml input text. You may also pass in a file-like object (e.g. a
   *StringIO*, file object or web request buffer), in which case noth- ing
   is written to disk.
