      Ruffle is a cross platform emulator for running and preserving
      Adobe Flash content. It is capable of running ActionScript 1, 2
      and 3 programs with machine-native performance thanks to being
      written in the Rust programming language.

      Additionally, overriding the `withRuffleTools` input to
      `true` will build all the available packages in the ruffle
      project, including the `exporter` and `scanner` utilities.
