Mapgen
From Spring
since version 92.0 spring contains a simple map generator. To test it, spring has to be started with a script.txt which contains two lines:
MapName=gen-123;
MapSeed=123;
where MapSeed is a random number and MapName a string for the mapname. The map have to not exist. Currently it only can generate a Greenfield like map.
