The case study brings them together into a complete, realistic-sized application (about sixty files, approximately 5,500 lines, including comments). It was written with the same care as the examples: each file begins with a comment explaining its role, and tricky sections are annotated in the code. The document’s commentary emphasizes what the examples did not show and refers to them for the rest.
