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.
