Re: [htmltmpl] TMPL_IF and TMPL_ELSE - how do I use this?

[Timm M. <tm...@ag...>]

You set it up just like a TMPL_VAR.  If the value of that variable is true 
(according to Perl's definition of truth), then that section is run.  It's 
just like doing:

if($var) {
     # Do something
}
else {
     # Do something else
}

Except HTML::Template (in its basic form) doesn't provide a way of doing 
elsif or doing complex comparisons (like $var == 3).
