      3 # KERNSRCDIR	Is the location of the top of the kernel src.
      4 # 		It defaults to ${BSDSRCDIR}/sys, but the top-level
      5 # 		Makefile.inc sets it to ${ABSTOP}/sys (ABSTOP is the
      6 # 		absolute path to the directory where the top-level
      7 # 		Makefile.inc was found.

      9 # KERNARCHDIR	Is the location of the machine dependent kernel
     10 # 		sources.  It defaults to arch/${MACHINE}

     12 # KERNCONFDIR	Is where the configuration files for kernels are
     13 # 		found; default is ${KERNSRCDIR}/${KERNARCHDIR}/conf.

     15 # KERNOBJDIR	Is the kernel build directory.  The kernel GENERIC for
     16 # 		instance will be compiled in ${KERNOBJDIR}/GENERIC.
