gdata.gauth | index /home/afshar/working/gdata-python-client/src/gdata/gauth.py

`Provides auth related token classes and functions for Google Data APIs.
Token classes represent a user's authorization of this app to access their
data. Usually these are not created directly but by a GDClient object.
ClientLoginToken
AuthSubToken
SecureAuthSubToken
OAuthHmacToken
OAuthRsaToken
TwoLeggedOAuthHmacToken
TwoLeggedOAuthRsaToken
Functions which are often used in application code (as opposed to just within
the gdata-python-client library) are the following:
generate_auth_sub_url
authorize_request_token
The following are helper functions which are used to save and load auth token
objects in the App Engine datastore. These should only be used if you are using
this library within App Engine:
ae_load
ae_save`
