Git extension to list the most recent branches, in most-recent-commit order, with a human-friendly interval display.

# GIT-RBAGO
#
# For any given git repository, this script will print out the
# (default) ten _most recently worked on_ branches, along with a
# fairly human-readable version of how long ago that was.
#
# Example:
#
# $ git rbago
# develop        19 hours ago
# master         21 hours ago
#
# Requirements:
#     Python 3.6+
#     timeago (https://github.com/hustcc/timeago)
