   2 # EXPERIMENTAL texture pack copying 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.
   7 #
   8 # Requirements:
   9 # - Python 3
  10 # - Python Library: Pillow
  11 # - ImageMagick
  12 #
  13 # Usage (to be simplified later):
  14 # - Put extracted texture pack into $HOME/tmp/pp
  15 # - Make sure the file “Texture_Conversion_Table.csv” is in the same directory as the script
  16 # - Run the script in its directory
  17 # - If everything worked, retrieve texture pack in texture_pack/
