+The DF_Caverns modpack was originally written based on the minetest_game. It made extensive use of various nodes and helper functions that came from minetest_game's constituent mods.
+
+When Mineclone games rose in popularity, the task of making it compatible was a daunting one - there were dependencies on minetest_game's mods scattered everywhere. To make the task manageable, I created this mod to serve as a central location where analogous objects could be taken from those games to be referenced in a generic way.
