    """
    libSplash aims at developing a HDF5-based I/O library for HPC simulations.
    It is created as an easy-to-use frontend for the standard HDF5 library
    with support for MPI processes in a cluster environment. While the
    standard HDF5 library provides detailed low-level control, libSplash
    simplifies tasks commonly found in large-scale HPC simulations, such as
    iterative computations and MPI distributed processes.
