+handler.cpp

+Provides a handler for processing XML elements found by the reader.

+The handler looks for <title> and <link> elements within <item> elements,
+and records the text found within them. Link information stored within
+rdf:about attributes of <item> elements is also recorded when it is
+available.
+
+For each item found, a signal is emitted which specifies its title and
+link information. This may be used by user interfaces for the purpose of
+displaying items as they are read.
