I've written up SuperDuper. You'll find it in the table of contents list on this page...
http://www.ideaspike.com/index2.shtml
...if you'd like to link to it, that's fine, but you don't want to link directly to the write-up, because that TOC list changes as I add software to the page and so the link to the spot on the page where the write-up is will change as well. The TOC itself will always point to the correct location for the write-up, no matter what else moves around on my site.
