     1.4 +pngquant converts 24/32-bit RGBA PNG images to 8-bit palette with alpha channel
     1.5 +preserved. Such images are compatible with all modern web browsers and a
     1.6 +compatibility setting is available to help transparency degrade well in
     1.7 +Internet Explorer 6. Quantized files are often 40-70 percent smaller than their
     1.8 +24/32-bit version. pngquant uses the median cut algorithm.
