A few of you asked for more information about the book.
You can find a press release of the book here:
http://www.pragprog.com/press_releases/programming-groovy-productivity-for-the-java-developer You can find table of contents here:
http://pragprog.com/titles/vslg You can also find an excerpt of a chapter at the above URL.
In one of the posts, someone asked for the preface.
When you click on the "Groovy for the
Java Eyes" excerpt,
you will also get the preface or Chapter I-Introduction.
Hope this helps.
