class Musl(Package):
"""Musl is a libc, an implementation of the standard library
functionality described in the ISO C and POSIX standards, plus common
extensions, intended for use on Linux-based systems. Whereas the kernel
(Linux) governs access to hardware, memory, filesystems, and the
privileges for accessing these resources, the C library is responsible
for providing the actual C function interfaces userspace applications
see, and for constructing higher-level buffered stdio, memory
allocation management, thread creation and synchronization operations,
and so on using the lower-level interfaces the kernel provides, as well
as for implementing pure library routines of the C language like
strstr, snprintf, strtol, exp, sqrt, etc.
Musl is a new general-purpose implementation of the C library. It is
lightweight, fast, simple, free, and aims to be correct in the sense of
standards-conformance and safety."""
