So your Git repository is getting ungainly large. What's causing it? Are the problem files still being updated, or are they the deleted ghosts of old binaries?
git cat-file --batch-check --batch-all-objects --unordered \
| sort --numeric-sort --key=3 \
| tail -n10 \
| xargs -L1 sh -c \
'pth=`git describe --always $0`; \
printf "%s %s %s %s\n" $0 $1 $2 $pth'
