+# Arch Linux ARM Chroot Builder
+#
+# Licensed under the GPLv2.
+#
+# This script builds an Arch Linux ARM chroot.
+# It does not include a kernel or other "low-level" components.
+# First, it downloads and installs packages to the workingdir,
+# then configures some basics, sets the root password to "root",
+# and then creates a rootts.tar.gz and/or a UBI image, ready to flash.
+#
+# Usage: ./chroot-builder workingdir
+#
+# NOTE: This script is interactive.
+# Agree to installing packages and answer "y" to cleaning the Pacman database.
