#  See Get Yahoo Mail OAuth2 Access Token for Desktop App 
#  for sample code showing how to obtain a Yahoo Mail access token.

#  In this example, our access token was previously saved to the following file which contains JSON like this:

#    "refresh_token": "AIenVXETSo0jklFBVkPS8vVm8E.Ej9ToRG.xDbDYmZ65WIs5t6CZhDrD",
#    "expires_in": 3600,
#    "token_type": "bearer",
#    "xoauth_yahoo_guid": "HGDQCVF5JB4YDOWHITQJFBHCWA"
