Usage: $0 [OPTION]

Options:
  -h, --help                    print this help, then exit

  -V, --version                 print version number, then exit

  -d  --directory DIR           use DIR directory for building LFS; all files
                                jhalfs produces will be in the directory
                                DIR/jhalfs. Default is \"/mnt/lfs\".

  -P, --get-packages            download the packages and patches

  -D, --download-client CLIENT  use CLIENT as the program for retrieving
                                packages (for use in conjunction with -P)

  -W, --working-copy DIR        use the local working copy placed in DIR
                                as the LFS book

  -L, --LFS-version VER         ckeckout VER version of the LFS book

  -T, --testsuites              add support to run the optional testsuites

  --no-toolchain-test           don't run the toolchain testsuites. This
                                disables also the build of TCL, Expect
                                and DejaGNU
                                
  --timezone TIMEZONE           set TIMEZONE as the local timezone. If not 
                                specified, Europe/London will be used.

  --page_size PAGE              set PAGE as the default page size (letter
                                or A4). This setting is required to
                                build Groff. If not specified, \"letter\"
                                will be used.

  -C, --kernel-config FILE      use the kernel configuration file specified
                                in FILE to build the kernel. If not found,
                                the kernel build is skipped.

  -M, --run-make                run make on the generated Makefile
