This collection of scripts, known as jhalfs, strives to create
accurate makefiles from the Linux From Scratch book series XML files.
This software is an evolution of the original "jhalfs-0.2" code.

A. Yes it does, try >> make

Q. "It still doesn't work"
A. jhalfs was designed to work against the developement versions of the LFS
A. jhalfs was designed to work against the development versions of the LFS
series of books. Consequently changes in a book(s) sometimes breaks older
versions of jhalfs. Before you start pulling out your hair download the
latest version of jhalfs to see if that solves your problem.

Q. "What is the function of the SRC_ARCHIVE variable?"
A. When then symlinked master.sh runs it creates a local copy of the
necessary packages in BUILDDIR/sources by downloading the files. If
the variable SRC_ARCHIVE is defined the software will first look in
this location for the file and, if found, will copy it to BUILDDIR/sources.
A. When jhalfs runs and packages download was selected, it creates a local
copy of the necessary packages in BUILDDIR/sources by downloading the
files. If the variable SRC_ARCHIVE is defined the software will first
look in this location for the file and, if found, will copy it to
BUILDDIR/sources.
If the files are not found in SRC_ARCHIVE _and_ you have write priv to
the directory any downloaded files will be mirrored there.
Q. "How do I set the SRC_ARCHIVE location?"
A. The best way to set the value of SRC_ARCHIVE is
export SRC_ARCHIVE=/wherever/you/store/downloaded/packages
OR
you can change the setting in common/config.
or you can set the full path in the proper menu entry.
Q. "Why have 2 copies of the files?"
A. The package files must be visible during the chroot phase and this is a
simple and reliable method of doing so. This method also handles the CLFS
build method where the final build may be done on a separate machine.
boot build method where the final build may be done on a separate machine.
Q. "What is the function of "User account" and "Group account" menu settings?"
A. If you are running jhalfs from a low or non-privileged account you may not
have the priv to create/delete the user needed to build temporally tools.
These settings allow you to use your own user and group name to do that
build steps.
These variables are adjustable also when invoking make:
Q. "What is the function of LUSER and LGROUP? There is no cmd line switch"
A. If you are running jhalfs from a low or non-priveledged account you may not
have the priv to create/delete accounts. These variables are adjustable
when invoking make.

The only changes to your account will be the creation of a NEW .bashrc

Q. "When I try to build CLFS the Makefile fails at the mid-point"
A. There could be numerous reasons for the failure but the most likely reason
is you are doing a cross-build using the 'chroot' method and the target is
not compatible with the host. If you choose to build using the chroot
