Very disappointing book. At almost $1/page this book is a joke. It is a very basic guide to a very detailed subject and I didn't learn anything new after reading it. The print is so large that it's obvious that the editor/author were trying hard to add volumne to make up for content. I've never seen a technical book with print so large my grandmother could read it without her glasses.
