# $Id$
#
# managing our work at the cryptobox
#
# usual workflow:
#   dfsbuild	- create the image directory with dfsbuild
#   config	- apply cryptobox specific changes to the image directory
#   harden	- remove unnecessary packages and disable developer features
#   iso		- create the iso image
#   isoz	- create a compressed iso image
#   burn	- burns the image on a cd-rw
#
# final action:
#   release	- the same as "dfsbuild config harden iso"
#
#
# problems of this script:
#  - has to run as root
#  - 'harden' is strangely integrated
#
# you may run this script with multiple arguments, e.g.:
#   cb-build.sh dfsbuild config iso
#
# the action "release" does what it says :)
#  (all developer's features like sshd, writable templates and
#   the test-suite are deactivated, some packages get removed)
