%description
MozJPEG improves JPEG compression efficiency achieving higher visual quality
and smaller file sizes at the same time. It is based on libjpeg-turbo and is
backward compatible with the libjpeg API. This package provides optimized
encoding tools: cjpeg, djpeg, jpegtran.

Files are installed to /opt/mozjpeg to avoid conflicts with system libjpeg.
