I'm trying to determine the neighborhood for a location, based on Zillow's freely published Shapefile data.

I don't really know anything about the Shapefile format, and am having some trouble finding tutorials online -- but I basically want to take latitude/longitude pairs, and run it against the Shapefile data to determine the corresponding neighborhood(s).

Can anyone point me in the right direction? Not even sure where to start.

This is where I've grabbed the Shapefile files: http://www.zillow.com/howto/api/neighborhood-boundaries.htm
