Plant a large rectangular area of trees.
Cht: PlantTrees [<SizeX>] [<SizeY>] [<type>]
This cheat plants a rectangular area of trees around the location of the sign. It is especially useful to plant trees for a lumber mill, just place a sign with Cht: PlantTrees on top of the lumber mill.
If SizeX is given, it specifies the size of the rectangle in the X direction. By default the size is just right to cover the range of a lumber mill (40 squares).
If SizeY is given, it specifies the size of the rectangle in the Y direction. If not given, the size in Y direction is the same size as in X direction.
Finally, you can specify the tree type as a number from 0 to the maximum tree type. If not given, random trees are planted.
