+rsslisting.cpp
+
+Provides a widget for displaying news items from RDF news sources.
+RDF is an XML-based format for storing items of information (see
+http://www.w3.org/RDF/ for details).
+
+The widget itself provides a simple user interface for specifying
+the URL of a news source, and controlling the downloading of news.
+
+The widget downloads and parses the XML asynchronously, feeding the
+data to an XML reader in pieces. This allows the user to interrupt
+its operation, and also allows very large data sources to be read.
