ext_shapelib - usage

ext_shapelib currently supports creation of new shape files, adding shapes and attributes to those files, and closing those files.

A list of currently available functions follows below.

shp_create() creates (or overwrites an existing) shapefile. shp_create also adds attribute fields to the dbf file - attribute definitions cannot be changed afterwards.

shp_add() adds a new shape to a shape file. Attribute values of the given shape are stored in the dbf file. Currently, only "simple" shape types are supported.

shp_close() closes a shape file, and flushes all written data to disk.
