Basically, I run a script like the one below once a day at the crontab:

#!/bin/bash
LANG=C
PATH=/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games

DIR=/some_temp_location/dtv-scan-tables

DATE="`git log -n1 '--pretty=format:%h %ai' |perl -ne 'print "$2-$1" if (m/([\da-f]+)\s+(\S+)/)'`"

TODAY_TAR=dtv-scan-tables-$DATE.tar
FILE="$TODAY_TAR.bz2"
REPO=/the_www_location/downloads/dtv-scan-tables/


run() {
	echo $@
	$@
	if [ "$?" != "0" ]; then
		echo "Error $?. Please fix."
		exit -1
	fi
}

run cd $DIR
run git pull /git/dtv-scan-tables.git/ master

CHANGES=`git log --pretty=oneline -n1`
if [ "$CHANGES" = "`cat .changes`" ]; then
	echo "tarball already updated to the latest changeset."
	echo "Nothing to do."
	exit;
fi

git archive --format tar --prefix "/usr/share/dvb/" HEAD >$TODAY_TAR
run bzip2 -f $TODAY_TAR

run mv $FILE $REPO
run ln -sf $FILE $REPO/dtv-scan-tables-LATEST.tar.bz2
(cd $REPO; md5sum *.bz2 > md5sum)
echo $CHANGES > .changes

Thanks for pointing it to me. I fixed the script.
