    '''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)
       environments.

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