The purpose of SingleSub is to a provide a set of
feeds. It consists of one Perl script and a set of XSLT templates, which provide RSS, HTML and Javascript tools used to subscribe to RSS feeds without restricting them to a specific aggregator. Instead, a dynamic list of aggregators is provided for the user to choose from. This list of RSS aggregators and how to subscribe to them is provided via several XML formats, so other tool developers can use them as well.
