While I was reading the Perl planet I found a link to a project called Plagger. It’s system for creating, changing and publishing feeds.

To create a new ‘program’, you need to make a config file. The example directory includes a bloglines2gmail config and a config for a ‘planet’ aggregator. Both are less than twenty lines of configuration. It’s really easy to create your own feeds with this.

Be sure to check out the presentations on the website, for an explaination of Plagger (the documentation is a bit light).
