    """Apptainer is an open source container platform designed to be simple, fast, and
    secure. Many container platforms are available, but Apptainer is designed for
    ease-of-use on shared systems and in high performance computing (HPC)

    Needs post-install chmod/chown steps to enable full functionality.
