Snow Leopard Server Developer Reference

Just received the book Snow Leopard Server Developer Reference by Daniel Eran Dilger. On 944 pages it is a much needed documentation of Apples newest server OS for less than 50$. Update: just rread over the book in three evenings and from what I have read until now, I can recommend it wholeheartedly! Helped me solve a problem with managed preferences in the first few hours of reading it!
