  12     Usage: $script [-d base_dir] [-k kernel_dir] [-i install_base]
  13     -d base_dir
  14               The base directory where the source will be extracted to and
  15               the release will be built.  If no -d option is provided,
  16               the default base_dir is the current pwd.
  17
  18     -k kernel_dir
  19               The base directory where a copy of the kernel sources,
  20               already configured; can be found. If no -k option is
  21               provided, the default kernel_dir is
  22               $base_dir/../release/src/linux/linux.
  23
  24     -i install_base
  25               The base directory where the resulting binaries will be
  26               installed and run from.  If no -i option is provided, the
  27               default install_base is /opt/brcm.
