"""openid.py: an openid library for web.py

Notes:

- This will create a file called .openid_secret_key in the 
   current directory with your secret key in it. If someone 
   has access to this file they can log in as any user. And 
   if the app can't find this file for any reason (e.g. you 
   moved the app somewhere else) then each currently logged 
   in user will get logged out.

- State must be maintained through the entire auth process 
   -- this means that if you have multiple web.py processes 
   serving one set of URLs or if you restart your app often 
   then log ins will fail. You have to replace sessions and 
   store for things to work.

- We set cookies starting with "openid_".
