This folder contains two simple examples illustrating how to use the Finite 
Domain Solver included with GNU Prolog with Logtalk. These examples are 
adapted, with permission from the original author, Daniel Diaz, from the GNU 
Prolog 1.3.0 distribution.

Print Logtalk, Prolog backend, and kernel versions (if running as a notebook):

```logtalk
%versions
```

Loading the example runs an initialization query that solves an alphacipher
puzzle and an crypt-arithmetic puzzle:

```logtalk
logtalk_load(clp_gprolog(loader)).
```
