I forgot to mention the database format :
(You can understand it from the source, but I'll take a low profile as I provided no doc AT ALL :-)

*******database.txt**********
add_fact(theory=> qw(foo bar baz));
add_fact(theory=> qw(foo tac toe));
add_fact(theory=> qw(tic tac toe));
add_fact(theory=> qw(tac lac toe));
*******database.txt**********

Now a little example on how to use it :

*********try.pl**********

#!/usr/bin/perl -w
use strict;
#use Devel::StealthDebug;

use lib '.';

use Perlog;
use Perlog2;

#my $pg = AI::Perlog->new;
my $pg2 = AI::Perlog2->new;


#$pg->load_from_file('database.txt');
$pg2->load_from_file('database.txt');

#
# Perlog2 should definitly export display ;-)
#
AI::Perlog2::display($pg2->theory(qw/$x tac $y/));
print "*********\n";
AI::Perlog2::display($pg2->theory(qw/?  $x tac $y/));
print "*********\n";
AI::Perlog2::display($pg2->theory(qw/tic tac toe/));
print "*********\n";
AI::Perlog2::display($pg2->theory(qw/tIc tac toe/));
*********try.pl**********<br>

I've updated the display function's code in my previous post to handle 'false' answers.
