in reply to Creating huge files with the Template Toolkit

I found this thread on the mailing list. Click here

It sounds like a bit of a hack, basically you alter the $OUTPUT token for the perl code TT generates.

In Template::Directive it is defined as:
$OUTPUT    = '$output .= ';

You can set it to something like this
$Template::Directive::OUTPUT = 'print ';

On the thread Andy notes that this will break WRAPPER and lists a few other caveats.
