The rest of the source code, apart from the Huffman codec optimizations, falls
under a less restrictive, BSD-style license (see README.) You can choose to
distribute libjpeg-turbo, as a whole, under this BSD-style license by simply
replacing the optimized jchuff.c and jdhuff.c with their unoptimized
counterparts from the libjpeg v6b source.
