%description
The libjpeg-turbo package contains a library of functions for manipulating
JPEG images. It supports architecture-specific SIMD instructions,
such as SSE/SSE2/AVX2, AltiVec, NEON, MIPS DSPR2, and Loongson MMI.
%if "%{flavor}" == "libjpeg-turbo"
It also includes the following command line utilities:
  djpeg - decompress a JPEG file to an image file
  jpegtran - lossless transformation of JPEG files
  rdjpgcom - display text comments from a JPEG file
  wrjpgcom - insert text comments into a JPEG file
  tjbench - a JPEG decompression/compression benchmark
