Yeah, I thought about that too, but I figured that descriptions were
already there so I may as well make it an option for the
search-engine-impared. :) I was also thinking about system
administrators and ordinary users trying to installing device drivers
and other such situations where they would have to look at their syslogs
or dmesg -- or just the lazy. :)
