Just to explain why I did not do this before - if you check the
hyperlink to the document it will contain some very long hash or
something similar and will not fit the one line. Either that is some
Yahoo! Groups protection or something else. Anyway, you have to go to
the files area and download that document
(external_procedures_impl_v1.pdf). Sorry for inconvenience. :)
