Unfortunately our server is hosted, so I can't fiddle the install.
Also, for a newbie like myself, that would be a fairly arcane bit of
knowledge about server install/configuration.

I've been using 'require_once(dirname(__FILE__)."/../
someaught.php")'...likely there's some hideous downside to doing it
that way, but it certainly has saved me some headaches trying to
resolve dependency calls when a file includes a file that includes a
file...I tried using Maarten Manders' smartloader class with it's
__autoload trick, but couldn't get it to work. :P
