content: This book really didn't give much at all. Much because of its useless explainations, that are probably really juicy if you already know it and pretty worthless if you don't... I didn't. Just one thing to do, attend all classes if you got this book for class litterature, and if you live in Canada or as I do in Sweden, use it as fire wood-substitute when it's cold...(Hmm does layout spell "n-o-t-e-p-a-d"?)
