 * This is small program used to convert a shapefile to a .xy file (GMT multisegment) for use in Generic Mapping Tools, you need shapelib to compile, get it from http://dl.maptools.org/dl/shapelib/
 * More information coming soon.


 * WIN32 .exe I compiled, no guarantees of fitness for any purpose, rapidshare : http://rapidshare.com/files/62146836/shp2gmt.zip
