Template::Exception has a type, which may be useful to you.  I'd
suggest grep'ing the code to see what some possible types are when it
throws Template::Exception errors.

That only works with things that throw exceptions, which process()
does not.  It makes you check for a true return value and then look at
$tt->error() or $Template::ERROR.  I recommend avoiding Error.pm's
try/catch anyway, because of the error-prone sub ref prototype trick
it uses.

The error() method should give you a Template::Exception object, as
described here:
