True to the name "Learning Perl/Tk" this book is a great fast-start into Perl/Tk. However, it only covers the very basic components of the Tk module. Most of these basic "widgets" are fundementally the same, but this book allocates a chapter to cover each one in complete detail. This results in a lot of redundant text. There are numerous standard composite widgets that need documented. These are not even mentioned in the book.
