GNU Prolog 1.0.0 is available.

Here are some basic information about GNU Prolog:

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

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 (DCG, global variables, OS interface, sockets,...).

GNU Prolog also includes an efficient constraint solver over Finite Domains
(FD). This opens contraint logic pogramming to the user combining the power
of constraint programming to the declarativity of logic programming.
