This reference is consistently bad. Please Zinn, just stop. I swear, every time I have tried to use this manual, I have not been able to complete the task. I have degrees, I have read my share of books, but rarely have I come across something this useless. Take it from a paying customer, buy something else, anything else. Use the internet, its free. For god's sake, just use youtube.
