#!/usr/bin/env python
# script to extract commit author's name from standard input. The
# input should be <AUTHOR>:<EMAIL>, one per line.
# This script expects the input is created by git-log command:
#
# git log --format=%aN:%aE
#
# This script removes duplicates based on email address, breaking a
# tie with longer author name. Among the all author names extract the
# previous step, we remove duplicate by case-insensitive match.
#
# So we can do this in one line:
#
# git log --format=%aN:%aE | sort | uniq | ./author.py > authors
