Web Development with Clojure, Third Edition: different paths (*)

At the beginning of every code-quote is the path to the corresponding file (very useful- thanks!). The first part of these paths is the project name which keeps changing throughout the book without the reader actually changing projects. Example: on page 87 the first path is guestbook-cljc/src/clj/guestbook/routes/home.clj, then on the following page it’s
guestbook-reagent/src/clj/guestbook/routes/home.clj. The reader who’s followed the book so far is using paths beginning with guestbook/.... This is slightly confusing.
