I wrote a simple shapefile dumping program using MapScript. It's distributed in
the mapscript/examples directory in the new 3.3 version. Dump.pl shows you
how to access the spatial side of a shapefile. You can use DBI and the 
DBD::Xbase module to access the .dbf side. The is also a 'create.pl' script you
can modify to take data from just about any perl accessible location and create
shapefiles. Be careful with polygon data as the shapefile specification talks about
vertex ordering for inner (i.e. holes) vs outer rings. MapServer does not require 
that ordering (at this time) but other packages may.

Does anyone know how to convert shapefiles to comma separated value files,
or these CSV files to Shapefiles?
