    longDescription = ''
      Mercury is a logic/functional programming language which combines the
      clarity and expressiveness of declarative programming with advanced
      static analysis and error detection features.  Its highly optimized
      execution algorithm delivers efficiency far in excess of existing logic
      programming systems, and close to conventional programming systems.
      Mercury addresses the problems of large-scale program development,
      allowing modularity, separate compilation, and numerous optimization/time
      trade-offs.
