long_description \
    Each NCO operator (e.g., ncks) takes netCDF or HDF input file(s), \
    performs an operation (e.g., averaging, hyperslabbing, or renaming), \
    and outputs a processed netCDF file. Although most users of netCDF \
    and HDF data are involved in scientific research, these data formats, \
    and thus NCO, are generic and are equally useful in fields like finance. \
    This version is OPeNDAP/DODS enabled, so it can be given \
    URLs to read remote datasets as if they were local netCDF files.
