    """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."""
