    """OpenMC is a community-developed Monte Carlo neutron and photon transport
    simulation code. It is capable of performing fixed source, k-eigenvalue, and
    subcritical multiplication calculations on models built using either a
    constructive solid geometry or CAD representation. OpenMC supports both
    continuous-energy and multigroup transport. The continuous-energy particle
    interaction data is based on a native HDF5 format that can be generated from ACE
    files produced by NJOY. Parallelism is enabled via a hybrid MPI and OpenMP
    programming model."""
