I am not sure what this means ... "The ability to enter non-Joomla! URL's into this area is coming soon! This will allow you to easily transfer a non-Joomla! site to Joomla using ARTIO JoomSEF and any of your old URL's will be redirected to the new page within Joomla!."

What is a custom URL according to JoomSEF? I need what the quoted text states ... I have an existing site that I am porting to Joomla and need full url aliasing. Is JoomSEF wrong for me?
