Hi Brent,
I can compile C++, and I'm interested. Is it possible to access the code?

Hi Paolo,
Your point is well taken. What seem to be the best solutions involve
reading in a shapefile and then writing out a new one. I was starting to
lean toward either PostGIS or Spatialite by using a SQL script sourced
within the relevant cli shell since my guess was that they would scale

Hi Paolo, Simon, and Noli,

All,
Is there a FOSS command line tool that runs under Linux for dissolving

works directly with shapefiles? There are a number of non-cli tools out
