Every one and their wife is using RSS these days, not least me. Here's the code for a really simple Perl RSS processor. It uses XML::RSSLite to do the XML processing, so it's really light weight. It's incredibly simple, and needs modification of code to change the output HTML. Still, it's useful for fetching someone's RSS and making it into HTML that you can paste into something else (perhaps by an SSI?). I use it to fetch my Blogroll via RSS and SSI include it, for example.

Whilst working all night (yes, it's true), we found that Flash Darts really helped pass the time while we couldn't really manage anything more productive.
