class Swipl(CMakePackage):
    """SWI-Prolog is a versatile implementation of the Prolog language.
    Although SWI-Prolog gained its popularity primarily in education,
    its development is mostly driven by the needs for application development.
    This is facilitated by a rich interface to other IT components by
    supporting many document types and (network) protocols as well as a
    comprehensive low-level interface to C that is the basis for high-level
    interfaces to C++, Java (bundled), C#, Python, etc (externally available).

    Data type extensions such as dicts and strings as well as full support
    for Unicode and unbounded integers simplify smooth exchange of data
    with other components."""
