[mkgmap-dev] Outlines of states/provinces

I’m new to mkgmap and am still learning the basics. Having said that, I’ve downloaded the US-South sub-region from geofabrik.de and I can see a country dividing line or boundary between the state of Texas and Mexico. It’s a thin grey line. I’d like to know how to create these boundaries. Can anyone provide a brief overview of how to go about this? I know this question demonstrates a real lack of knowledge about how this whole thing works, but I’m learning as I go. Thanks a bunch, for anyone willing to tackle this ;-) Steve Steven Miller srmj71@hotmail.com (717) 562-2879
