description                 language for scientific data processing and visualization
long_description \
    The NCAR Command Language (NCL), a product of           \
    the Computational & Information Systems Laboratory      \
    at the National Center for Atmospheric Research (NCAR)  \
    and sponsored by the National Science Foundation,       \
    is a free interpreted language designed specifically    \
    for scientific data processing and visualization.
