        A desktop turtle graphics library for Lua 5.4, inspired by Python's
        turtle module and Seymour Papert's Mindstorms. Students write normal
        Lua scripts; a Cairo-rendered graphics window appears.

        Features: multi-turtle, animated undo, REPL mode (readline), full
        Python turtle API compatibility for ~40 commands.
