This is a new World map file format which will be used in the PGE as a main world map / episode file format.
One of the main differences when compared to the old WLD file format, like LVLX, is that all parameters are marked. This allows you to place parameters in any order. New files will always be readable for old versions of the program, because of the unknown markers being ignored. And you have the freedom of adding new parameter markers in the file without losing compatibility.
