    6 # ${BRANCH}: needed, style branch of the kernel
    7 # ${KERNEL_CONFIG}: optional, needed if you want to override the default
    8 # searchpath ${SOURCEDIR}/${PNAME}/config-${PVER}-${BRANCH}-${PBUILD}
    9 #
    10 # ${PSUBVER}: optional, only needed for 2.6.x.x naming scheme
    11 # ${EXTRAVERSION}: optinal, extra version for the kernel name
    12 # default setting is ${PSUBVER}-${BRANCH}-${PBUILD}
    13 # ${KERNEL_IMAGE_PATH}: override the default KERNEL_IMAGE_PATH (to build xen images for e.g.)
    14 # ${COMPRESS_MODULES}: compresses the kernel modules with given compressor (gzip|bzip2|xz)
    15 # ${LINUX_FIRMWARE}: remove included firmware bits if requested
    16 # set the version here like USE_LINUX_FIRMARE="20110605"
    17 # version "internal" keeps the bits too
    18 #
