      Gnash is a GNU Flash movie player.  Flash is an animation file format
      pioneered by Macromedia which continues to be supported by their
      successor company, Adobe.  Flash has been extended to include audio and
      video content, and programs written in ActionScript, an
      ECMAScript-compatible language.  Gnash is based on GameSWF, and
      supports most SWF v7 features and some SWF v8 and v9.
