Internationalization

Let's convert a program to run in other languages

        print "Hello there!\n";
        print "Should I erase all your files (yes/no)?  ";
        chomp(my $response = <>);
        if ($response eq 'yes') {
          system("rm -rf $ENV{HOME}");
        }

The program shouldn't actually say Hello there!
Instead, it should consult a database of texts
In Mexico, the database will contain ¡Buenos dias! instead
