Custom Terrain Generation
This mod is a customizable, algebraic terrain generator that alters the distribution of land, water, and void cells at the start of a new game.
A wide variety of terrain generation algorithms are included, as well as the ability to combine them in many ways or write your own algorithm.
Updated to support V 1.1.

I use this mod enough and people have been asking for an update.
If Erst comes back and updates the original mod or has a problem with update, I will take this down.
