    longDescription = ''
      ImageWorsener is a cross-platform command-line utility and library for
      image scaling and other image processing. It has full support for PNG,
      JPEG, BMP formats, experimental support for WebP, read-only support for
      GIF, and limited support for some other image formats. It’s not as
      fast or memory-efficient as some utilities, but it’s very accurate.
