Planet is a flexible feed aggregator, this means that it downloads feeds and aggregates their content together into a single combined feed with the latest news first. It uses Mark Pilgrim's Ultra-liberal feed parser so can read from RDF, RSS and Atom feeds and Tomas Styblo's template library to output static files in unlimited formats based on a series of templates. Planet was written for the Planet Debian and Planet GNOME websites by Scott James Remnant and Jeff Waugh . It was originally based on 'spycyroll'. WWW: http://www.planetplanet.org
