# Script: build_installer.sh
# Purpose: Build the Slackware installer from scratch (multiple architectures)
# Author: Stuart Winter <mozes@slackware.com>
# Eric Hameleers <alien@slackware.com>

################################################################################
#
# Notes: [1] If you want to use your own _skeleton_ initrd (containing only
# the directory layout plus all the scripts) you just make it
# available as ./sources/initrd/skeleton_initrd.tar.gz
#
# The script will look for the directory 'sources' first in your
# working directory, and next in the script's directory (whatever is
# found in your working directory takes precedence).
