This is a simple script that sits between an old non-oauth enabled twiter client and twitter.

1) Register an application here http://dev.twitter.com/apps/new
   Choose Client, Read & Write
2) From http://dev.twitter.com/apps Click on the application
   Save Consumer key and Consumer secret
3) Scroll up and click My Access Token
   Save Access Token (oauth_token) and Access Token Secret (oauth_token_secret)

4) Fill twitter.ini
   HOST_NAME -> host
   PORT_NUMBER -> port
   CONSUMER_KEY -> Consumer key
   CONSUMER_SECRET -> Consumer secret
   TOKEN -> Access Token
   TOKEN_SECRET ->Access Token Secret
   USER -> A username you choose (Same as the twitter client)
   PASS -> A password you choose (Same as the twitter client)

5) Run it:
   python ./twitter-proxy.py

6) Configure your client with the username and password
7) Configure your client to connect to the host and port

Problems:
 A recent enough httplib2 and python-oauth2 are needed.
 Tested it with httplib2-0.6.0.tar.gz

 If you don't have a recent enough httplib2:
   wget -c http://httplib2.googlecode.com/files/httplib2-0.6.0.tar.gz
   tar -zxvf httplib2-0.6.0.tar.gz
   ln -s httplib2-0.6.0 httplib2

   git clone http://github.com/simplegeo/python-oauth2.git

Limitations:
* Only basic authentication is supported. The client I'm using doesn't support Digest.
* Unlikely to implement Digest authentication within this script. I use it behind apache
  mod_proxy so apache can do the Digest stuff and the script can then be modified not to require
  any authentication
* Only one user is supported. I'm not going to implement the full OAuth.
* It's not a daemon. Use screen to run it.
