+#!/bin/bash
+#
+# This script is the second stage in bootstrapping a Slackware build
+# to a new platform or architecture.  Running stage1.sh with no arguments
+# builds a cross-development environment, then cross-builds a minimal
+# rootfs.  Once you have this minimal rootfs booted (or chroot'd), run
+# stage2.sh (this script) in that rootfs to build the rest of the
+# bootstrap packages.
+#
+# This script assumes that all the needed sources are installed in
+# $SLACKSOURCE (below) by stage1.sh.  Each build installs into /usr.
+#
+# You may pass a single package name on the command line to rebuild
+# just that one package.
+#
+# The master upstream for this script is:
+#   git://fedorapeople.org/~djdelorie/bootstrap.git
+#
+# ------------------------------------------------------------
+#
+#	      --- NOTES FOR PACKAGE PORTING ---
+#
+# This script is stage TWO of a bootstrap process.  EVERYTHING that
+# this script uses MUST be provided by the stage ONE script -
+# filesystem, utilities, sources, etc.  Please keep this in mind when
+# editing this script - anything you do manually to "prepare" for your
+# build, will NOT be reproducible.
+#
+# Please make sure your package is not in either stage1 or stage2, and
+# that nobody else is already working on your package, before
+# starting.  Grep is your friend.  See the wiki page for details.
+#
+# There are FOUR places you must edit when adding packages to the
+# bootstrap build:
+#
+# 1. Add a clause at the end of this script to actually build your
+#    package.
+#
+# 2. Add your package to the "" case at the beginning of the package
+#    list, about a page down from these comments.  Put in the order in
+#    which it needs to build based on its dependencies.
+#
+# 3. Add your package source to the list at the end of the stage1 script
+#    so that your sources are available in the bootstrap rootfs.
+#
+# 4. Update the Fedora/ARM bootstrap wiki page.
+#
+# If you attempt to add a package and discover some unsatisfied build
+# dependency, add a clause for it here that documents the dependency
+# and exits with a non-zero code.  In that case, do not add your
+# package to the "" case.
