Rich Site Summary [L1 ] or RDF Site Summary [L2 ]. There are some heated debates [L3 ] about what RSS is but at its core it's an XML syntax for providing summaries of news based websites. An RSS document consists of one or more channels with one or more items. Each item is usually a news story with a title, a link and possibly a description. Newer versions of RSS [L4 ] provide for more properties for each item.
Steve's Wiki [L5 ] has RSS capabilities. That is you can get the Recent Changes page as an RSS file.
Petteri K offers
lynx -source http://www.iki.fi/petterik/rss.cgi > rss.cgi
tclsh rss.cgi 0b00 as a demonstration of RSS capabilities.
A nice discussion from another Wiki [L6 ].
