    # Put this anywhere on your $PATH (~/bin is recommended). Then git will see it
    # and you'll be able to do `git churn`.
    #
    # Show churn for whole repo:
    #   $ git churn
    #
    # Show churn for specific directories:
    #   $ git churn app lib
    #
    # Show churn for a time range:
    #   $ git churn --since='1 month ago'
    #
    # (These are all standard arguments to `git log`.)
