+%description
+pngquant is a command-line utility and a library for lossy
+compression of PNG images.
+
+The conversion reduces file sizes by converting images to 1/2/4/8-bit
+paletted PNG format with alpha channel (often 60-80%% smaller than
+24/32-bit PNG files). Generated images are compatible with all modern
+web browsers, and have better fallback in IE6 than 24-bit PNGs.
