# an interactive python script to assist in getting access tokens for OAuth v1
# APIs. requires python's OAuth2 library (pip install oauth2)
#
# run from the command line like so:
#
# $ python three_legged_oauth_helper.py --consumer_key=<ckey> \
#   --consumer_secret=<csecret> \
#   --request_token_url=<request_token_url> \
#   --authorize_url=<authorize_url> \
#   --access_token_url=<access_token_url>
#
# ... where <ckey> is your consumer key, <csecret> is your consumer secret,
# and <request_token_url>, <authorize_url>, <access_token_url> are the
# request token URL, authorize URL, and access_token URL of the service you're
# targeting (respectively). Default URLs are supplied for the Tumblr API.

basically the same thing as the example on the oauth2 github page, I guess. but it was helpful for me to write it out by hand.
