Package squidpony.tileset Description
Pre-constructed Tileset objects in different styles, that DungeonBoneGen consumes (not intended for external use).
It is currently pretty much impossible to create tilesets beyond these, since these were ported from a public domain C
library that, unfortunately, does not document how its tilesets were created or how to make more.

previously converted to JSON and then to this Java source)
