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