Here's a link for it... sorry for the confusion.

And now a rant...
If you're a very large webhosting company (Big Commerce) that advertises web services and user configurable content management (Big Commerce) then every time you push an update to the configurable content management your software should NOT break all the links and reorganize your customers' websites...
Incidentally that's why you couldn't find the thing, it was compressed into a single listing with the Remage barrels.
We'll fix it but for the immediate couple days (I'll try to fix it shortly) this link will work.
Again,sorry about the mixup.
