: << inline_doc
Installs a set-up to build BLFS packages.
You can set these variables:
TRACKING_DIR  : where the installed package file is kept.
                (default /var/lib/jhalfs/BLFS)
INITSYS       : which books do you want? 'sysv' or 'systemd' (default sysv)
BLFS_ROOT     : where the installed tools will be installed, relative to $HOME.
                Must start with a '/' (default /blfs_root)
BLFS_BRANCH_ID: development, branch-xxx, xxx (where xxx is a valid tag)
                (default development)
LFS_BRANCH_ID : development, branch-xxx, xxx (where xxx is a valid tag)
                (default development)
Examples:
1 - If you plan to use the tools to build BLFS on top of LFS, but you did not
use jhalfs, or forgot to include the jhalfs-blfs tools:
(as root) mkdir -p /var/lib/jhalfs/BLFS && chown -R <user> /var/lib/jhalfs
(as user) INITSYS=<your system> ./install-blfs-tools.sh
2 - To install with only user privileges (default to sysv):
TRACKING_DIR=$HOME/blfs_root/trackdir ./install-blfs-tools.sh

This script can also be called automatically after running make in this
directory. The parameters will then be taken from the configuration file.
