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. :)
