Well, aren't you going to share the reduced file?

Okay fine, let's see for ourselves:

    # Setup
    git clone [email protected]:RustPython/RustPython.git && cd RustPython && cargo build --release
    git clone [email protected]:tekknolagi/scrapscript.git && cp scrapscript/scrapscript.py .

    # Download interesting.sh, replace the path to RustPython
    chmod +x interesting.sh

    # Command in article:
    nix run nixpkgs#creduce -- --not-c interesting.sh scrapscript.py

Niiice:
