    """Exodus II is a C++/Fortran library developed to store and retrieve
    data for finite element analyses. It's used for preprocessing
    (problem definition), postprocessing (results visualization), and
    data transfer between codes.  An Exodus II data file is a random
    access, machine independent, binary file that is written and read
    via C, C++, or Fortran API routines.  This package *only* installs
    the C and optionally Fortran library for exodus.  If you want the full
    suite of exodus-releated tools including the IOSS library, install
    the seacas package instead of this package.
