If there were manual sections that answered these questions, I bet that
they'd be called "10.1.2" and "10.1.3". I suppose that those sections
could address some aspects of what they discuss more clearly than they
do, but it'd probably be more productive to ask any remaining questions
after reading those sections than to not do so ...
