     # +++ variables +++
     #
    # CLEANFILES    Additional files to remove for the clean and cleandir targets.
    #
    # KMOD          The name of the kernel module to build.
    #
    # KMODDIR       Base path for kernel modules (see kld(4)). [/boot/kernel]
    #
    # KMODOWN       KLD owner. [${BINOWN}]

    # KMODLOAD      Command to load a kernel module [/sbin/kldload]
    #
    # KMODUNLOAD    Command to unload a kernel module [/sbin/kldunload]
    #
    # PROG          The name of the kernel module to build.
    #               If not supplied, ${KMOD}.o is used.
    #
    # SRCS          List of source files
    #
    # DESTDIR       Change the tree where the module gets installed. [not set]
    #
    # MFILES        Optionally a list of interfaces used by the module.
    #               This file contains a default list of interfaces.
    #
    # EXPORT_SYMS   A list of symbols that should be exported from the module,
    #               or the name of a file containing a list of symbols, or YES
    #               to export all symbols.  If not defined, no symbols are
