BTW, it's no longer neccessary to do that to use Aristotle's lovely theme -- it's been promoted to a proper theme, with a place on the drop-down in user settings. This puts much less load on PM, and is the prefered Way To Do It now. It also means that maintance can be shared amongst the pmdevils, and doesn't have to be just on Aristotle's sholders. (If you're a pmdev, remember that you can explicitly give the displaytype=viewcode parameter -- and have to, in this case.)
