Summary: A minimal libc subset for use with initramfs.
Name: klibc
Version: @@VERSION@@
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 >= 2.6.0
Packager: H. Peter Anvin <hpa@zytor.com>
Prefix: /usr
Vendor: Starving Linux Artists
%define klibcdir %{_prefix}/lib/klibc
%define libdocdir %{_docdir}/%{name}-%{version}-%{release}
%define bindocdir %{_docdir}/%{name}-utils-%{version}-%{release}
%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.

# Note: libc.so and interp.o are technically -devel files, but
# put them in this package until we can make really, really sure
# the dependency system can avoid confusion. (In fact, it would be
# good to eventually get them out of here, so that multiple runtimes
# can be installed should it be necessary.)
