"""cx_Freeze build script.

    python fetch_ffmpeg.py      -> ffmpeg/ (bundled ffmpeg + ffprobe, once)
    python setup.py build_exe   -> build/exe.win-*/mp4trim.exe
    python setup.py bdist_msi   -> dist/mp4trim-<version>-win64.msi

The installer is self-contained: it ships Python, Qt, the MSVC runtime and
ffmpeg/ffprobe, so the target PC needs nothing else installed.
