description         Silky smooth JPEG decoding - no more artifacts!
long_description    JPEG encoding loses information. But it is JPEG decoding that introduces artifacts\
                    by filling the missing information with noise. ${name} is smarter and fills the\
                    missing information to create the smoothest possible picture.
