Description: Run simple direct gravitational N-body simulations. The
        package can access different external N-body simulators (e.g.
        GADGET-4 by Springel et al. (2021)
        <doi:10.48550/arXiv.2010.03567>), but also has a simple
        built-in simulator. This default simulator uses a variable
        block time step and lets the user choose between a range of
        integrators, including 4th and 6th order integrators for
        high-accuracy simulations. Basic top-hat smoothing is available
        as an option. The code also allows the definition of background
        particles that are fixed or in uniform motion, not subject to
        acceleration by other particles.
