it uses Tiki (https://www.ohloh.net/p/tikiwiki) as a base but enhances it with a lot of personalized code to allow for the use of Ajax interfaces, to create a free multimidia archive and to integrate with an icecast streaming server. Polvo is a sub-project that allows for seamless integration with Tiki's codebase.
