%description
musl is an implementation of the C standard library built
on top of the Linux system call API, including interfaces
defined in the base language standard, POSIX, and widely
agreed-upon extensions. It is lightweight, fast, simple,
free, and strives to be correct in the sense of standards
conformance and safety.

%package libc
Summary:	Fully featured lightweight standard C library for Linux
Provides:	%{name}-libs%{?_isa} = %{version}-%{release}

This package provides the additional development files for
statically linking musl into programs and libraries.
	
%package gcc
Summary:	Wrapper for using gcc with musl
Requires:	%{name}-devel = %{version}-%{release}
Requires:	gcc
 
%description gcc
musl is a C standard library to power a new generation
of Linux-based devices. It is lightweight, fast, simple,
free, and strives to be correct in the sense of standards
conformance and safety. 
This package provides a wrapper around gcc to compile
programs and libraries with musl easily.
