Wordpress Category RSS feed links

In working on the post related to software updates and making sure it was easy to find the category feed JUST for that led me on a "round the world" kind of quest to find a way to put the category feeds in the footer of pages in Wordpress. The first thing I tried was this this category livebookmarks plugin, which gives some options to browsers that recognize feeds in the header of the page. It's interesting, but I may wind up uninstalling. What I HAVE found is this solution which was EXACTLY what I was looking for.

I hope to post the code details here, but they I'll need to investigate how to get them to show up properly (some worked, some didn't in my test.)
