# Texture pack movement utility.
# This Python script helps in converting Minecraft texture packs. It has 2 main features:
# - Can create a Minetest texture pack
# - Can update the MineClone 2 textures
# This script is currently incomplete, not all textures are converted.
#
# Requirements:
# - Python 3
# - Python Library: Pillow
# - ImageMagick
#
# Usage (to be simplified later):
# - Put extracted texture pack into $HOME/tmp/pp
# - Make sure the file “Texture_Conversion_Table.csv” is in the same directory as the script
# - Run the script in its directory
