      The <application>libexif</application> package contains a library for
      parsing, editing, and saving EXIF data. Most digital cameras produce
      EXIF files, which are JPEG files with extra tags that contain information
      about the image. All EXIF tags described in EXIF standard 2.1 are
      supported.
