> 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 to link the code of most unused built-in predicates. Beside the native-code compilation, GNU Prolog offers a classical interactive interpreter (top-level) with a debugger.
