+"""
+Visit the Twitter developer page and create a new application:
+
+ https://dev.twitter.com/apps/new
+
+This will get you a CONSUMER_KEY and CONSUMER_SECRET.
+
+When users run your application they have to authenticate your app
+with their Twitter account. A few HTTP calls to twitter are required
+to do this. Please see the twitter.oauth_dance module to see how this
+is done. If you are making a command-line app, you can use the
+oauth_dance() function directly.
+
+Performing the "oauth dance" gets you an ouath token and oauth secret
+that authenticate the user with Twitter. You should save these for
+later so that the user doesn't have to do the oauth dance again.
+
+read_token_file and write_token_file are utility methods to read and
+write OAuth token and secret key values. The values are stored as
+strings in the file. Not terribly exciting.
+
+Finally, you can use the OAuth authenticator to connect to Twitter. In
+code it all goes like this::
+
+ MY_TWITTER_CREDS = os.path.expanduser('~/.my_app_credentials')
+ if not os.path.exists(MY_TWITTER_CREDS):
+ oauth_dance("My App Name", CONSUMER_KEY, CONSUMER_SECRET,
+ MY_TWITTER_CREDS)
+
+ oauth_token, oauth_secret = read_token_file(MY_TWITTER_CREDS)
+
+ twitter = Twitter(auth=OAuth(
+ oauth_token, oauth_token_secret, CONSUMER_KEY, CONSUMER_SECRET))
+
+ # Now work with Twitter
+ twitter.statuses.update('Hello, world!')
