structure corresponds to the book's example label paths.
The "extensions" directory:

examples. Its PIL package, or the newer Pillow for of it, must
be installed for some image-based GUI examples (e.g., PyPhoto).
The "changes" directory:
logs changes made to this package, gives outputs of code admin
scripts presented in Chapter 6, and includes snapshots of both
files in the book's suport website and O'Reilly's errata site.
