The previous description was taken verbatim from the source code comment at wp-includes/general-template.php, which itself referenced this Trac ticket. It makes sense in context, but taken alone and without the ticket's example, it's very unclear what the function does. Hopefully the example I gave will make it a bit clearer, since it shows how to use the result of calling wp_meta() and relates it to the default behaviour. Justin Ryan 05:06, 12 October 2011 (UTC)
