The performances of GNU Prolog are very +encouraging (comparable to commercial systems). + +Beside the native-code compilation, GNU Prolog offers a classical +interactive interpreter (top-level) with a debugger. + +The Prolog part conforms to the ISO standard for Prolog with many +extensions very useful in practice (e.g., global variables, OS +interface, sockets). + +GNU Prolog also includes an efficient constraint solver over finite domains. +This opens contraint logic programming to the user combining the power of +constraint programming to the declarativity of logic programming.") + (license (list gpl2+ lgpl3+))))
