I wrote and maintained this document for a while, but it has fallen into disrepair. It has not been updated since FC5. For the most part, it is now replaced with the more actively maintained content at:
http://fedoraproject.org/wiki/SELinux
If anyone is interested in taking over this document, you are free to. Otherwise, I'm going to tell Dan Walsh and friends to mine it for any value, and put the ore on the Wiki.
