I just know in comparing it to say gentoo and their portage tool, that the code inside portage is really complex (in Python no less). I personally have no objection to removing it, but there may be those that want to keep it.

Note that I do not want to remove (yet) the BLFS directory
and the tools it contains. Just the blfs-tool script.
Actually, I am finalizing a tool which should allow
automating much of BLFS, including Perl modules,
python modules and D-Bus bindings. I succeeded
in detecting circular dependencies and in linearizing
the book according to user instructions (choice
of which package you build first when a circular
dependency is detected), and actually everything is
working, except I am having somme trouble with the dependencies
in BLFS, which are not always up to date. Please do not consider what I
just said as a critic. Reading the blfs-dev mailing list,
I understand how hard it is to maintain this book. I am actually
offering to help with this tool, which, being dumb as a
tool, unveil many deficiencies...
For example, building an X server in the order of the chapter
24 works, but trying to build by saying "I want xorg-server,
so I go to the dependencies of xorg-server, then to the
dependencies of them and so on, until I find packages with no
dependencies, which I build first and then I go back building
packages once all their dependencies have been built", it ends up
with a wrong order (and actually no mesalib!). Well, becoming OT,
More to come in a forthcoming thread.
