Folks, Dave has said this better than I can. He's said it more ways than I can come up with.

One thing I haven't seen yet in this thread: Most, if not all, PDF readers have a find function, often accessed by control-F. So if you want to know if CO2 can be used, or if you HAVE to have bumpers, or any one of a number of other answers to questions you have, you might try picking a key term or two (for the examples I gave, "CO2" and "bumper" would work), plugging it into the find function, and seeing what you find.
