    longDescription = ''
      A subset of the tools from the upstream Faust `tools/benchmark/`
      directory: dynamic-faust, faustbench-llvm, faustbench-llvm-interp,
      faustbench-interp, interp-tracer (binaries built against libfaust.a),
      plus the scripts faustbench, faust2object, and faust-tester.

      This package intentionally excludes the JACK/GTK runners (dynamic-jack-gtk,
      faust-osc-controller, signal-tester, box-tester) and the WASM bench
      tools to keep the closure small. They can be packaged separately if
      needed.
