%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. musl is lightweight, fast, simple,
free, and strives to be correct in the sense of standards-conformance
and safety.
