%description
The kernel package contains the Linux kernel (vmlinuz), the core of your
Red Hat Linux operating system.  The kernel handles the basic functions
of the operating system:  memory allocation, process allocation, device
input and output, etc.

%package source
Summary: The source code for the Linux kernel.
Group: Development/System
Prereq: fileutils
Requires: gawk, make
Requires: gcc >= 2.96-98

%description source
The kernel-source package contains the source code files for the Linux
kernel. These source files are needed to build custom/third party device
drivers. The source files can also be used to build a custom kernel that is
better tuned to your particular hardware. Make sure you understand the
support implications of building your own custom kernel.
