+%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.

This is klibc, what is intended to be a minimalistic libc subset for
use with initramfs. It is deliberately written for small size,
-minimal entaglement and portability, not speed. It is definitely a
+minimal entaglement, and portability, not speed. It is definitely a
work in progress, and a lot of things are still missing.
The following is the last known status of various architectures:
- Known to work: alpha arm ia64 i386 ppc s390 s390x sparc
- sparc64 x86_64*
- Works static, not shared: mips* arm-thumb sh* parisc
- Might work: ppc64
- Need porting work: cris m68k mips64 v850
-
- x86_64: requires a kernel header patch (to be created)
- mips, sh: linker problem; might work with fixed linker
-
- Shared library support requires binutils 2.13.90.0.4 or later on
- many architectures.
-
- Note that even the "known to work" ones likely have bugs. Please
- report them if you run into them.
