this script is good to connect a twitter user to an IRC channel.

dependencies 

tweepy - twitter streaming api
oyoyo - irc chat library

make sure you follow tweepy's instructions for oAuth
make sure you register your app: http://twitter.com/oauth_clients


##example python code
import tweepy
auth = tweepy.OAuthHandler(consumer_token, consumer_secret)
try:
    redirect_url = auth.get_authorization_url()
except tweepy.TweepError:
    print 'Error! Failed to get request token.'

##take the url and login with the account you want to link
## and notate the value for verifier

auth.set_request_token(auth.request_token.key, auth.request_token.secret)

try:

except tweepy.TweepError:
    print 'Error! Failed to get access token.'

##use these two values for the values of key and secret in the script
token.key
token.secret
