8#
9# * A file named $HOME/autolivebuilder.config specifying shell
10#   variable assignments for:
11#   - error_addr: An email address to send errors to
12#   - release: The Ubuntu release to base the live CDs off of
13#   - release_version: The version number of that release
14#   - arch: Which architecture to use for the live CD
15#   - mirror: Which Ubuntu mirror to use
16#   - gpg_opts: A bash array of options to pass to gpg. This should
17#     include which keys to sign the checksums files with
18#   - live_dir: The directory to put the live CDs into
19
20# Send all output to a logfile.
