# how to unfollow everyone who isn't following you
# By Jamieson Becker (Public Domain/no copyright, do what you will)

# Easy instructions, even if you don't know Python
#
# 1.  Install pip (apt-get install python-pip) and then
#     pip install tweepy, which is the python twitter client
#
# 2.  create a new app in your account at dev.twitter.com
#     and then plug in your consumer and app keys below.
#     Trim all whitespace at beginning/end of your keys.
#
# 3.  the twitter app needs to have permissions changed to
#     read-write, as apps are read-only by default.
#
# 4.  Execute this script: python unfollow.py
