#!/usr/bin/env ruby
# This script performs an OAuth authorized POST with multipart encoding to
# http://twitter.com/account/update_profile_image.json
#
# This code is primarily taken from my Grackle library's implementation at
# http://github.com/hayesdavis/grackle
#
# RUNNING THIS WILL CHANGE AN ACCOUNT'S PROFILE IMAGE. BE CAREFUL.
#
# Instructions to run this script:
# 1) Install the OAuth gem if you don't have it (sudo gem install oauth)
# 2) Create an oauth.yml file in your working directory (see format below)
# 3) Run "ruby update_profile_image.rb /Path/to/image/file"
#
# oauth.yml format:
# consumer_key: APP_CONSUMER_KEY_FROM_TWITTER
# consumer_secret: APP_CONSUMER_SECRET_FROM_TWITTER
# token: ACCESS_TOKEN_FOR_A_USER_RETRIEVED_VIA_OAUTH_FLOW
# token_secret: ACCESS_TOKEN_SECRET_FOR_A_USER_RETRIEVED_VIA_OAUTH_FLOW
