Plagger is a pluggable RSS/Atom aggregation platform that allows users to create custom applications by combining different plugin modules. It provides plugins for subscription, aggregation, filtering, publishing, notification, and search functions. The document gives examples of how Plagger can be used to build applications like a Bloglines to Gmail importer, an RSS bot for IRC, and a planet generator. However, the author notes that Plagger currently lacks documentation and has many dependencies, technical issues, and feature requests logged on its website.
