+Summary: A minimal libc subset for use with initramfs.
+Name: klibc
+Version: 0.181
+Release: 1
+License: BSD/GPL
+Group: Development/Libraries
+URL: http://www.zytor.com/mailman/listinfo/klibc
+Source: http://www.kernel.org/pub/linux/libs/klibc-%{version}.tar.gz
+BuildRoot: %{_tmppath}/%{name}-%{version}-%{release}-buildroot
+BuildRequires: kernel-source >= 2.6.0
+Packager: H. Peter Anvin <hpa@zytor.com>
+Prefix: /usr
+Vendor: Starving Linux Artists
+
+%description
+%{name} is intended to be a minimalistic libc subset for use with
+initramfs.  It is deliberately written for small size, minimal
+entanglement, and portability, not speed.  It is definitely a work in
+progress, and a lot of things are still missing.
+
+%package kernheaders
+Summary: Kernel headers used during the build of klibc.
+Group: Development/Libraries
+
+%description kernheaders
+This package contains the set of kernel headers that were required to
+build %{name} and the utilities that ship with it.  This may or may
+not be a complete enough set to build other programs that link against
+%{name}.  If in doubt, use real kernel headers instead.
+
+%package utils
+Summary: Small statically-linked utilities built with klibc.
+Group: Utilities/System
+
+%description utils
+
+This package contains a collection of programs that are statically
+linked against klibc.  These duplicate some of the functionality of a
+regular Linux toolset, but are typically much smaller than their
+full-function counterparts.  They are intended for inclusion in
+initramfs images and embedded systems.
