   6 Installs a set-up to build BLFS packages.
   7 You can set these variables:
   8 TRACKING_DIR  : where the installed package file is kept.
   9                  (default /var/lib/jhalfs/BLFS)
  10 BLFS_ROOT     : where the installed tools will be installed, relative to $HOME.
  11                 Must start with a '/' (default /blfs_root)
  12 BLFS_BRANCH_ID: development, branch-xxx, xxx (where xxx is a valid tag)
  13                 (default development)
  14 INITSYS   : which book do you want? 'sysv' or 'systemd' (default sysv)
  15 Examples:
  16 1 - If you plan to use the tools to build BLFS on top of LFS, but you did not
  17 use jhalfs, or forgot to include the jhalfs-blfs tools:
  18 (as root) mkdir -p /var/lib/jhalfs/BLFS && chown -R <user> /var/lib/jhalfs
  19 (as user) INITSYS=<your system> ./install-blfs-tools.sh
  20 2 - To install with only user privileges (default to sysv):
  21 TRACKING_DIR=$HOME/blfs_root/trackdir ./install-blfs-tools.sh
  22
  23 This script can also be called automatically after running make in this
  24 directory. The parameters will then be taken from the configuration file.
