The document you’re looking for was here, but has been removed. It’s not coming back.
In the summer of 2012 I updated this site, rearranging a lot of the content and also removing a lot of cruft. (It’s amazing what can accumulate in ten years.) While many things were moved to new locations, the page you’ve requested has been cast upon the trash heap and will not be coming back. That might be because it was out of date, no longer in line with the purpose of this site, or just badly written.
Sometimes, you just need to clean house.
