    <<~EOS
      MVTools will not be autoloaded in your VapourSynth scripts. To use it
      use the following code in your scripts:

        core.std.LoadPlugin(path="#{HOMEBREW_PREFIX}/lib/libmvtools.dylib")
    EOS
  end

  test do
    script = <<~EOS.split("\n").join(";")
      import vapoursynth as vs
      core = vs.get_core()
      core.std.LoadPlugin(path="#{lib}/libmvtools.dylib")
    EOS

    system Formula["python@3.8"].opt_bin/"python3", "-c", script
