%description
    Mercury is a pure logic programming language intended for the
    creation of large, fast, reliable programs. The syntax of Mercury is
    based on the syntax of Prolog, but semantically the two languages
    are very different due to Mercury's purity, its type, mode,
    determinism and module systems.
