I have some basic shapefiles of the world, and then I have tiger
shapfiles.  The world shapefiles have some duplicated data such as US
roads.  I'd like to trim all data within the US out of the world data.=20
This seems like a somewhat common task so I am hoping there is a tool
out there?  Something like trim north_american_highways.shp with
usa_polygon.shp...  Hints? tips? evil vibes?
