In section 9: "If you are going to use GRP, now would be a good time to execute the following commands:" The problem with this is that GRP isn't explained here--nor is an explanation linked to from here. (Consider the newbie that's already on information overload.) At the very least, "GRP" should link to the information in section 15 so users can decide if they want it or not--or at least find out what the heck it is. Wrapping "GRP" in an <abbr> tag would be nice, too.
I will add a small blurb at the beginning of the doc.
