+The Switch Digger works on the premise that today's routers and switches
+are chock-full of information that very few people use.  It puts that data
+to good use and cross-references what the network knows with what it knows
+to arrive at the closest possible location.
+
+This program is designed to track down computers to the finest level of
+information available at the moment.  Sometimes this can mean an exact
+description of a port in a building anywhere in an enterprise.  Other
+times this may just be a vague notion of a faraway network.  The results
+are only as good as the data you feed to it.
