Creates 4 feeds :
trdf => rdf in theme (template : feed-rdf.php)
trss => rss 1.0 in theme (template : feed-rss.php)
trss2 => rss 2.0 in theme (template : feed-rss2-comments.php and feed-rss2.php)
tatom => atom in theme (template : feed-atom-comments.php and feed-atom.php)
Those feeds look for a feed template into the theme directory. 
If no template is found into the theme directory the feed uses the default wordpress feed template.
