Create a bundle and tag the codebase so we can make bundles incrementally

create_git_bundle.sh

#!/bin/bash
# If on Windows, run this using the Git Bash

cd /path/to/git/repo

# Create a git bundle which includes only commits from
# the commit tagged "last_bundle" up to the present state
# of my "master" branch
git bundle create my_code.bundle last_bundle..master

# Tag the current commit with "last_bundle",
# replacing the previous tag, so next time we run this,
# this commit is the starting point of our bundle.
git tag -f last_bundle master

# Move my bundle somewhere outside my git repo,
# e.g. my home directory
mv my_code.bundle ~
