//! Implements the functionality to extract assets bundled by [RenPy](https://renpy.org/) archives.
//!
//! **Credits**: This tool has been ported to Rust from the [rpatool](https://github.com/Shizmob/rpatool) repo, originally written in Python.
//!
//! **Disclaimer**: Use this library only archives on which the authors allow modification or extraction. The unauthorized use is highly
//! discouraged since this poses most likely a license violation.
