## Git Authors

To extract the names of all Git contributors,
run this piece of Python code inside the codebase:

    from subprocess import check_output
    authors = check_output(['git', 'log', '--pretty=format:"%aN <%aE>"', 'HEAD'])
    sortkey = lambda n : n.split("<",1)[0].split()[-1].lower() if "<" in n else n
    for name in sorted(set(authors.splitlines()), key = sortkey):
        print(name)
