Wordpress - How can I hide the_meta output if it is empty?

Vote count:

I've created a function and hook to insert some custom field information on some of my posts.

<?php the_meta(); ?>

I have added some CSS formatting (box with background) for display. Problem: if I have a post without any custom fields defined it displays an empty box. How can I prevent it from outputting the empty if there is nothing to display? All I can find is information on specific field types and and can't extrapolate from it. I'm definitely not a php boss.
