Named Binary Tag (NBT) is a binary format designed for and used by the game Minecraft to store various data including worlds, player data and many other things. This project provides a way to access those data by simply mounting the corresponding data file as a file system, then reading and writing any value as usual file system nodes. NBT parser and writer are originally written by Lukas Niederbremer as cNBT project which this project is based on. This package provides the FUSE-based file system implementation, as well as NBT maintenance command-line tools and library (cNBT).
