I concur with the author's assessment of Darkwynd comments. While this book does not attempt to compete with the reference tome written by David Flanagan, it is exceptionally well written with a highly consistent style. Of particular value, it seems that all of the examples are self explanatory. If you get lost in in a particular place, you can still learn something from the next chapter. Also, many technical books suffer from the "casting pearls of wisdom" syndrome, where it is apparent that the author is being influenced by his new fame. This does not appear to be the case with Mr. Manger. Good work !
