editing /etc/rc.conf was just given as a example for the post.
Yes the whole man sed reads like Greek. For a neophyte programmer I can 
not even begin to comprehend what its saying. That man page needs 
examples of use. You have forgotten that those man pages are for 
reference for people who all ready know how to use it. Its not intended 
for novices. So yes it's useless to me.
