description         command-line utility and library for lossy compression of PNG images

long_description    pngquant is a {*}${description}. \
                    The conversion reduces file sizes significantly (often as \
                    much as 70%) and preserves full alpha transparency. \
                    Generated images are compatible with all modern web \
                    browsers, and have better fallback in IE6 than 24-bit PNGs.
