Thanks to everyone who has provided great feedback on the book so far. Please continue to send in your comments, suggestions, etc. We will be publishing the names of those who provide useful feedback on the book.
Also, we are planning to add an appendix to the book that will capture the best examples and use-cases from the community. The appendix will be a Jython cookbook of sorts. Please add your best example(s) to the wiki at http://wiki.python.org/jython/DocumentationAndEducation
and perhaps you will see your work published in the cookbook appendix.
Thanks again, and all of the authors are looking forward to the continued feedback and great examples for the book.
