2 # EXPERIMENTAL texture pack converting utility.
3 # This Python script helps in converting Minecraft texture packs. It has 2 main features:
4 # - Can create a Minetest texture pack (default)
5 # - Can update the MineClone 2 textures
6 # This script is currently incomplete, not all textures are converted.
13 # - Make sure the file “Conversion_Table.csv” is in the same directory as the script
14 # - Run ./Texture_Converter.py -h to learn the available options
