Subject: Implement xAuth support.
X-Git-Url: https://vcs.fsf.org/?a=commitdiff_plain;h=28e975bd921f9645df29c1107d573918c97becec;p=tweepy.git

Implement xAuth support.

xAuth allows you to exchange an username and password
pair for an OAuth access token.
See http://apiwiki.twitter.com/Twitter-REST-API-Method:-oauth-access_token-for-xAuth
