Is there a way to have the feed be a little different for a theme? Like, I have a favicon.ico in one of my themes, and I use that for the site by having the line
<link rel="shortcut icon" type="image/x-icon" href="<?php bloginfo('template_directory'); ?>/favicon.ico" /> in my theme. I want to do the same thing for my rss feed, but I don't want to just edit the global wp-rss2.php file, in case I ever want to switch to another theme or something. Can I put wp-rss2.php in a theme?
