 Usage: $0 ${BOLD}[OPTION]

${RED}IMPORTANT:${OFF} Only supported command line switches are listed here.
           For more fine-grained setups you must edit the relevant
           configuration files placed under ${BOLD}common/${OFF} and ${BOLD}$(echo $PROGNAME | tr [a-z] [A-Z])/${OFF}

Options:
${BOLD}  -h, --help${OFF}
        print this help, then exit

${BOLD}  -V, --version${OFF}
        print version information, then exit

${BOLD}  -B, --book VER${OFF}
        use VER version of the book as the system to build.
        Supported VER values are:
          dev*, trunk, SVN = aliases for the Development version of {C,H}LFS
          branch-NAME = a branch of name NAME
          VERSION = the version of a stable released book
        To know what branches and stable books work with this version of jhalfs
        please see http://wiki.linuxfromscratch.org/alfs/wiki/SupportedBooks

${BOLD}  -D  --directory DIR${OFF}
        use DIR directory for building ${BOLD}$(echo $PROGNAME | tr [a-z] [A-Z])${OFF}; all files jhalfs-X produces
        will be in the directory DIR/${SCRIPT_ROOT}.
        The current setting for BUILDDIR is "$BUILDDIR"

${BOLD}  -G, --get-packages${OFF}
        download the packages and patches. This assumes that the server declared
        in the configuration file has the proper packages and patches for the
        book version being processed.

${BOLD}  -O, --optimize${OFF}
        Optimize [0-2]
          0 = no optimization
          1 = optimize final system only
          2 = optimize both temporary tools and final system
        Edit common/opt_config{,.d/*} and common/opt_override as desired.

${BOLD}  -T, --testsuites N ${OFF}
        Run test suites  [0-3]
          0 = none
          1 = only final system Glibc, GCC and Binutils testsuites
          2 = all final system testsuites
          3 = all temporary tools and final system testsuites
        In CLFS and HLFS, 3 is an alias to 2

${BOLD}  -W, --working-copy DIR${OFF}
        use the local working copy placed in DIR as the $(echo $PROGNAME | tr [a-z] [A-Z]) book

${BOLD}  -C, --comparison TYPE${OFF}
         do iterative comparison analysis. This extends the total build time
         considerably because the entire final system will rebuild itself
         the number of times specified by ITERATIONS in common/config.
         Types allowed are:
           ICA   = do ICA as designed by Greg Schafer
           farce = do the farce analysis designed by Ken Moffat
           both  = perform both ICA and farce analysis

${BOLD}  -F, --fstab FILE${OFF}
        use FILE as the /etc/fstab file for the ${BOLD}$(echo $PROGNAME | tr [a-z] [A-Z])${OFF} system. If not specified,
        a default /etc/fstab file with dummy values is created.

${BOLD}  -K, --kernel-config FILE${OFF}
        use the kernel configuration file specified in FILE to build the kernel.
        if the file is not found, or if not specified, the kernel build is skipped.

${BOLD}  -M, --run-make${OFF}
        run make on the generated Makefile

${BOLD}  -R --rebuild${OFF}
        clean the build directory before performing any other task. The directory
        is cleaned only if it was populated by a previous jhalfs-X run.
