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

This package provides kernel headers and makefiles sufficient to build modules

against the kernel package.
