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