description	GNU Prolog compiler

long_description	\
		GNU Prolog is a free Prolog compiler with constraint	\
		solving over finite domains developed by Daniel Diaz.	\
		GNU Prolog accepts Prolog+constraint programs and	\
		produces native binaries (like gcc does from a C	\
		source). The obtained executable is then stand-alone.	\
		The size of this executable can be quite small since	\
		GNU Prolog can avoid linking the code of most unused	\
		built-in predicates. The performance of GNU Prolog is	\
		very encouraging (comparable to commercial systems).	\
		Beside native-code compilation, GNU Prolog offers a	\
		classical interactive interpreter (top-level) with a	\
		debugger.
