-# shown in a hierarchical format to show how smaller parts are concatenated
-# to form the larger and final value, with values coming from places like
-# the Makefile, kernel config options, make command line options and/or
-# SCM tag information.

-# $(VERSION) eg, 2
-# $(PATCHLEVEL) eg, 6

-# when not overridden by using "make LOCALVERSION=". This indicates that the
