%description
Guetzli is a JPEG encoder that aims for excellent compression
density at high visual quality. Guetzli-generated images are
typically 20-30%% smaller than images of equivalent quality
generated by libjpeg. Guetzli generates only sequential
(nonprogressive) JPEGs due to faster decompression speeds
they offer.
