SimplePie is a PHP library that parses RSS feeds. There are several WordPress plugins that use SimplePie so to avoid conflicts caused by having multiple versions of SimplePie installed, the guys that make SimplePie decided to make their own WordPress plugin which only loads the SimplePie plugin so that any other plugin can use SimplePie without causing conflicts with other plugins.
