+%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.

+%package devel
+Summary: Libraries and tools needed to compile applications against klibc.
+Group: Development/Libraries
+Requires: klibc = %{version}-%{release}
+
+%description devel
+This package contains the link libraries, header files, and gcc
+wrapper scripts needed to compile applications against klibc.
+
+%package utils
+Summary: Small utilities built with klibc.
+Group: Utilities/System
+Requires: klibc = %{version}-%{release}
+
+%description utils
+This package contains a collection of programs that are 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.
