Well, holy smokes.  Am I blind, aside from immersing myself in a  
rather large man page, where would I have learned this commands?   
These are each FAQ lines in their own right as far as I can see.  I  
very much think I represent the end user to a degree.  Not afraid to  
read at all, but man pages often times lack examples, which are some  
of the best ways to learn for me.
