+     "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 to link the code of most unused built-in
+predicates.  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.")
