     This script, jhahlfs, strives to create an accurate makefile
   directly from the xml files used to generate the Hardened Linux From
   Scratch document.
     The usage of this script assumes you have read and are familiar with
   the book and therefore the configuration variables found in jhahlfs.conf
   will have meaning to you. There are a limited number of command line
   switches which, if used, will override the config file settings.

   NOTES::
   *.  The resulting Makefile takes considerable time to run to completion,
   lay in a supply of caffeine beverages.

   *.  The document, Hardened Linux From Scratch, specifies a Linux kernel
   >=2.6.2 and GCC >=3.0 for proper compilation.

   *.  It is recommended that you temporarily unpack your linux kernel and
   run <make menuconfig> and configure the kernal as per the book and save
   the resulting .config file.

   *.  Chapter07 contains numerous command files which require customizing
   before you start 129-console, 131-profile, 133-hosts, 134-network,
   135-fstab, 136-kernel.

Options:

${BOLD}  --readme
${OFF}        print a small readme file, then exit
${BOLD}  -V, --version
${OFF}        print version number, then exit
${BOLD}  -d  --directory DIR
${OFF}        use DIR directory for building HLFS; all files jhahlfs produces will be
        in the directory DIR/jhahlfs. Default is \"/mnt/lfs\".
${BOLD}  --rebuild
${OFF}        clean the build directory before to perfom any other task. The directory
         is cleaned only if it was populated by a previous jhahlfs run.
${BOLD}  -P, --get-packages
${OFF}        download the packages and patches. This assumes that the server declared in the
        jhahlfs.conf file has the proper packages and patches for the book version being
        processed.
${BOLD}  -W, --working-copy DIR
${OFF}        use the local working copy placed in DIR as the HLFS book
${BOLD}  -L, --HLFS-version VER
${OFF}        checkout VER version of the HLFS book. Supported versions at this time are:
        dev* | trunk | SVN     aliases for Development HLFS
${BOLD}  --fstab FILE
${OFF}        use FILE as the /etc/fstab file for the HLFS system. If not specified,
        a default /etc/fstab file with dummy values is created.
${BOLD}  -C, --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
