# General idea:
# Foreach branch in origin:
#   Foreach log entry since last checkpoint
#     Foreach file in log entry
#       Store file as a change set
#       

# get branches using: git ls-remote --heads origin
# get name of current branch: git rev-parse --abbrev-ref HEAD
# get all logs using: git log --name-only --pretty=format:"%h %ai %s" --all --no-merges --since=6.months.ago
