Thanks... but it seems a little excessive. I was thinking of something
much simpler; along the lines of...

#!/bin/sh

STAGE=/staging/dwmw2/git

cd /home/dwmw2/git/snapshot-2.6

git pull || exit 1

LASTRELEASE=`ls -rt .git/tags | grep -v git | grep -v MailDone | tail -1`
LASTTAG=`ls -rt .git/tags | grep -v MailDone | tail -1`

CURCOMMIT=`commit-id`
LASTCOMMIT=`cat .git/tags/$LASTTAG`
RELCOMMIT=`cat .git/tags/$LASTRELEASE`

[ "$LASTCOMMIT" = "$CURCOMMIT" ] && exit 0

CURTREE=`tree-id $CURCOMMIT`
#LASTTREE=`tree-id $LASTCOMMIT`
RELTREE=`tree-id $RELCOMMIT`

if echo $LASTTAG | grep -q -- -git ; then
	OLDGITNUM=`echo $LASTTAG | sed s/^.*-git//`
	NEWGITNUM=`expr $OLDGITNUM + 1`
	NEWTAG=`echo $LASTTAG | sed s/-git$OLDGITNUM/-git$NEWGITNUM/`
else
	NEWTAG=$LASTTAG-git1
fi

echo $commit-id > $STAGE/$NEWTAG.id
# This is, unfortunately, in chronological order. Walking the tree would
# be better.
git log $CURCOMMIT ^$RELCOMMIT > $STAGE/$NEWTAG.log
git diff -r $RELTREE -r $CURTREE | gzip -9 > $STAGE/patch-$NEWTAG.gz

echo $CURCOMMIT > .git/tags/$NEWTAG
