A world map for the game BZFlag, or Battlezone Capture the Flag, that is stored completely in plaintext and defines the entire mesh of the battlefield as well as all object locations such as teleporters and spawn locations. It can also define primitives such as cubes and spheres. Because of the way these files are stored, they can technically be edited by any common text editor, though the complexity of the data usually demands that it be done through a map editor such as BZEdit.
