I mean by modular, that the book will be made up of several "modules"
or part, which can be bought separately and which aim different goal
:
one will help the reader to learn the fundamentals, one will deal
with
advanced use, one will be rather a reference manual for every-day’s
use, and one will present case studies.
So to answer to your question, it will take a bit from each of the
three books you mentioned.
Several authors will contribute, and the work will be shared
according
to each ones skills, specialization and availability.
