Usage:
mapgenerator [optional-params] [output: string...]
Options:
-h, --help Display this help page.
-v, --version false Show version info.
-w=, --width= 1920 Width of the map to be generated.
--height= 1080 Height of the map to be generated.
-b=, --biome= "temperate" Biome type (arctic, temperate, desert).
-p, --perlin false Use Perlin instead of Simplex noise.
- Temperate
- Temperate
- More biomes (ie. color schemes).
- Gradient color change for altitude.
