[Templates] nested wrappers and variables

Wed, 7 Jun 2006 18:25:53 -0400

If this needs to occur in every single template, then it may be easier
to just use the PRE_PROCESS directive when creating your Template
Toolkit object:

my $template = Template->new( PRE_PROCESS => 'base.tmpl' );

Anything you declare in the PRE_PROCESS will be visible in all of your
templates.

Cheers,
