i agree completely.  the problem i'm having is not knowing which
commands i can *leave* *out* of an intro doc because they have little
or no value to a regular user.  sometimes the helptool entry will
admit as much, sometimes it won't, and i'm left guessing.

anyway, i'm going to do a little more work on this and see what i can
come up with.
