About the Book
This book is just a compilation of the great documentation available at http://ceylon-lang.org/documentation/1.0/tour.
The purpose of this compilation is to provide the Ceylon documentation in multiple formats, because the web is not the only place for reading xD
But if you want an interactive experience i recommend you to go to their site..
