   3 # This is the top-level makefile - derived from the Junos version
   4 #
   5 # If a subdir that matches the requested target exists, we assume
   6 # a build target and initialize DIRDEPS, dirdeps.mk does the rest.
   7 #
   8 # Otherwise we include Makefile.xtras and hope it knows what to do.
