description	The Mercury Programming Language
long_description	\
		Mercury is a new 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.
