Your idea is a great improvement to the current section, but I think it
would be better to use the same scheme as the one used by the FreeBSD
GNOME team for HAL, i.e, using operator group as in
http://www.freebsd.org/gnome/docs/faq2.html#q19
This would keep a consistency between our docs and would be compatible
with GNOME and other things using HAL.
