MapScript: drawing points with Perl

[P Kishor]

Hi Benoit,

Attached is a small example that adds points to a shapefile. It was
written for a custom application, but you can easily adjust it to your
needs. As you can see, you don't even need MapScript to add points.
You can manipulate Shapefiles directly using Geo:: Shapelib module.

Hope this helps you.

Puneet.
