Plugin Name: Redirect Parent to First Child
Plugin URI: http://www.nathanrice.net/parent-to-first-child
Description: This plugin will do a 301 redirect on top-level parent pages, to their first child page, based first on menu order, then post title if no menu order is set.  It only redirects if a *published* child page actually exists.
Version: 0.1
