+## How to set up autobuild (for automatically updating grml-live.git and
+## build packages out of git tree and install them, e.g. for usage on
+## daily.grml.org):
+# echo "deb file:/home/grml-live-git/grml-live.build-area/ ./" >> /etc/apt/sources.list.d/grml-live.list
+# adduser --disabled-login --disabled-password grml-live-git
+# visudo -> add "grml-live-git ALL=NOPASSWD: /usr/bin/apt-get"
+# su - grml-live-git
+# mkdir /home/grml-live-git/grml-live.build-area
+# git clone git://git.grml.org/grml-live.git
+# git config --global user.name "Grml-Live Git Autobuild"
+# git config --global user.email "grml-live-git@$(hostname)"
+#
+# Finally install a cron job (as user grml-live-git) like:
+# 30 00 * * * cd /home/grml-live-git/grml-live.git/ && env AUTOBUILD=1 scripts/release_helper.sh >/home/grml-live-git/grml-live-build.log
+#
+# Tip: To find out the build date of the installed grml-live package just run:
+#
+# % apt-cache policy grml-live | grep 'Installed.*autobuild'
+# Installed: 0.13.1~autobuild1300450381
+#
+# and run "date -ud @$STRING" where $STRING is the number
+# behind the "autobuild", like:
+# % date -ud @1300450081
+# Fri Mar 18 12:08:01 UTC 2011
