  32 %description headers
  33 Kernel-headers includes the C header files that specify the interface
  34 between the Linux kernel and userspace libraries and programs.  The
  35 header files define structures and constants that are needed for
  36 building most standard programs and are also needed for rebuilding the
  37 glibc package.
