# 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
