How is lumber graded

Had a visit on Monday to a local Mill and I'm wondering if someone can
explain to me how lumber is graded? From what I've seen over the years
different people are grading wood differently. Whats the rules for grading.
I'm specifically looking at pine and cedar for now.

As always, it "depends" on which lumber at what mill...

Hardwood and it's relatives are graded differently from
softwoods.

http://www.softwood.org/species%20&%20grades%20web/sgweb/EN/S&G.htm
http://www.natlhardwood.org/inspection.asp?userid=

That last link will allow you download the "grading rules"

To make things more interesting, most manufactured
stuff is graded an entirely different way.(plywood,mdf,etc,etc)
