%package devel-%{kernel_package_string}
Version:    1
Release:    %mkrel 1
Summary:    XEN kernel devel files
Group:      System/Kernel and hardware
Provides:   kernel-devel = %{kernel_version}
Autoreqprov: no

%description devel-%{kernel_package_string}
This package contains the kernel-devel files that should be enough to build 
3rdparty drivers against for use with the %{kname}-%{buildrel}.

%package source-%{kernel_package_string}
Version:    1
Release:    %mkrel 1
Summary:    XEN kernel sources
Group:      System/Kernel and hardware
Provides:   kernel-source = %{kernel_version}
Autoreqprov: no

%description source-%{kernel_package_string}
This package contains the source code files for the Linux 
kernel. Theese source files are only needed if you want to build your own 
custom kernel that is better tuned to your particular hardware.

%package debug-%{kernel_package_string}
Version:  1
Release:  %mkrel 1
Summary:  Xen kernel debug files
Group:    Development/Debug
Requires: glibc-devel
Provides: kernel-debug = %{kernel_version}
Autoreqprov: no

%description debug-%{kernel_package_string}
This package contains the kernel-debug files that should be enough to 
use debugging/monitoring tool (like systemtap, oprofile, ...)

%package doc-%{kernel_package_string}
Version:    1
Release:    %mkrel 1
Summary:    XEN kernel documentation
Group:      System/Kernel and hardware
Autoreqprov: no

%description doc-%{kernel_package_string}
This package contains documentation files form the kernel source. Various
bits of information about the Linux kernel and the device drivers shipped
with it are documented in these files. You also might want install this
package if you need a reference to the options that can be passed to Linux
kernel modules at load time.
