The functionality of intersect.cpp is now included in GeographicLib. You can install this library in Mac machines with brew install geographiclib. Then do man IntersectTool.
OK, thanks.
OK. Thanks for the update. I'll slap a "GOING AWAY AT SOME POINT" notice on my cgi-bin scripts. Any estimate on when this might be? If I replace "AT SOME POINT" by "ON 2026-12-31", will I be safe? Or am I being too greedy.
