create_username

#!/usr/bin/env python3
"""
On sites where I don't want to use my standard username (@alexwlchan) --
for example, if I'm starring content but not creating anything -- I create
alliterative usernames from the names provided by Docker.

e.g. on GitHub I might use "goofy_galileo"

This script generates an alliterative username for me.

Usage: pass a single letter as first argument, and it offers five suggestions:

    $ ./usernames.py a
    angry_almeida
    admiring_ardinghelli
    admiring_austin
    amazing_aryabhata
    admiring_albattani
