+# on the Debathena build server--i.e. debuild@debuild.mit.edu. The

+# * A keytab installed in $HOME/keytab containing a keytab for
+# daemon/HOSTNAME, which should have write access to
+# /mit/debathena/live
+#
+# * A GPG secret key to sign the checksums for the live CDs.
+#
+# * A file named $HOME/autolivebuilder.config specifying shell
+# variable assignments for:
+# - error_addr: An email address to send errors to
+# - release: The Ubuntu release to base the live CDs off of
+# - release_version: The version number of that release
+# - arch: Which architecture to use for the live CD
+# - mirror: Which Ubuntu mirror to use
+# - gpg_opts: A bash array of options to pass to gpg. This should
+# include which keys to sign the checksums files with
+
+# Send all output to a logfile.
