man Web::Simple::AntiquatedPerl (3): the slides from the talk

WHAT?

Web::Simple was originally introduced in a talk at the Italian Perl Workshop, entitled Antiquated Perl.
The video is available on the Shadowcat site: <http://www.shadowcat.co.uk/archive/conference-video/ipw-2009/antiquated>
If you don't particularly want to watch me confusing a bunch of Italian perl mongers, the slides are reproduced below.
