Cheers Ken for the great reply...as always you get the thought process moving in the right direction!

I don't see any MVC-violation; please explain more about what you meant

In the first solution I came up with, I was suggesting passing the language specific text from the script to the template.

my $vars;
if ($lang eq 'en') {
    $vars = {
        'heading'   => 'Dies ist eine Einführung',
        'text'      => 'Hier ist ein Beispiel für einige Inhalte',
        'seemore'   => 'mehr sehen...',
    };
} elsif ($lang eq 'au') {
    $vars = {
        'heading'   => 'G\'Day, this is an intro',
        'text'      => 'Hey Sport, just a little example',
        'seemore'   => 'want more...',
    };
} else {
    # Default to English
    $vars = {
        'heading'   => 'This is an introduction',
        'text'      => 'Here is an example of some content',
        'seemore'   => 'see more...',
    };
}
$template->process('intro.tt', $vars);

I wouldn't implement it like that, but it shows my thought process...

I quickly moved on from there and went for having the template variables in their own template file and using a PROCESS directive to set the correct language. I only included the first option so you could get a glimpse of how my mind dealt with the stages of developing the idea.

I'll come back to the rest of your post in a while.
