Make a "map diff" tool to visualizes changes between two version of a map #2323
migrated from the wiki easycoding page, not my own idea.
Some text diff tools do better than plain command-line diff by the way... still, a visual diff tool would be much better. I think a side-by-side diff (with altered hexes hilited in some way on both maps) would be nicer than just adding map labels though; but of course that's also more work.
I'd say this should be available both from the command-line and from the map editor.
