Modern Front-End Development for Rails: sample code missing main directory (p. xvi)

There is no main directory in the zip file at http://media.pragprog.com/titles/nrclient/code/nrclient-code.zip

p. xvi says “The version of the code in the main directory is the complete app setup with all the data structures”

maybe it was decided this directory is somehow redundant?

Yes, it’s redundant with the first directory of chapter 1, I think.

that makes sense. thanks!
