32Provides: kernel-headers = %{version}
33%description headers
34Kernel-headers includes the C header files that specify the interface
35between the Linux kernel and userspace libraries and programs. The
36header files define structures and constants that are needed for
37building most standard programs and are also needed for rebuilding the
38glibc package.
