git-stats

#!/usr/bin/env bash

# usage:
#		git-stats #gives stats for the whole branch
#		git-stats --author="yourname here" #gives stats for specific author
#
# though not all tested, this should be compatible with all limiting options supported by git-log (https://www.kernel.org/pub/software/scm/git/docs/git-log.html#_commit_limiting)
