# This makefile is used to generate the kernel documentation,
# primarily based on in-line comments in various source files.
# See Documentation/kernel-doc-nano-HOWTO.txt for instruction in how
# to document the SRC - and how to read it.
# To add a new book the only step required is to add the book to the
# list of DOCBOOKS.
