+
+## This is based on the first part of the LFS manual, in regards to
+## the files that would reside in /tools. The three exceptions are 
+## wget, Python, and Perl is compiled fully.
+
+## Also, currently the script does not deal with
+## determing if there exist /etc/resolv.conf, so I leave that
+## up to you.
+
+## The initial meat for this was found at 
+## http://dev.gentoo.org/~vapier/bootstrap-portage, but
+## has been heavily modified due to doing "UNINTENDED THINGS"
+## That and the developer making that script intended it
+## to be installed on an already functioning system not
+## shifted to /tools, and well, yah.
+
+## NOTE ON PATHS: It's assumed /bin:/usr/bin:/sbin ... /tools/bin are
+## already set for the PATH variable.

+# CFLAGS, CHOST, ACCEPT_KEYWORDS, ARCH
+# NOTE: These are where you can change the processor
+# architecture you want to build for. There's also the 
+# make.profile that needs to be set later on, based on 
+# ACCEPT_KEYWORDS. (ACCEPT_KEYWORDS functions based on 
+# architecture. For example, an x86 install would just be x86, 
+# PowerPC would be ppc, et cetera.

+# We need an initial directory structure to make things easier on us

+# on me wanting a directory NOTE: This is assuming /etc exists, as

+# NOTE: There exist the sys-apps/baselayout ebuild. Perhaps this would
+# be a nice thing to parse initially. Until then, ugly hack!

+# We also need an ugly hack right now, in order to utilize hard-coded
+# paths by the Gentoo scripts. Luckily, by using symlinks with /tools
+# prefix, it makes it easy to go in later and remove everything
+# portage didn't install, and it's only the /bin directory
+ln -s /tools/bin/* /bin/
+ln -s /tools/bin/* /usr/bin/
+# Why both? It wants python in /usr/bin. Let's just be safe in case
+# it wants others
+
+### ****WARNING******
+### The following is because I used a different script to bootstrap Python,
+### not the LFS way (bootstrap-prefix.sh from the Prefix-Portage files)
+### So take this out if you built it with LFS

+# file and just parse that, to ensure we're not missing any new additions
