Help with

So I’ve been struggling with this if anyone can help. I want to create an author list using something like this:
<?php list_authors( $optioncount, $exclude_admin, $show_fullname,
$hide_empty, $feed, $feed_image ); ?>

but I don’t understand the code enough.
I just wish to display a list of all authors, full name, bio, and rss link.

Something I could use in a template file would be great.

Thanks
