Obtaining a Refresh Token

The following program can be used to obtain a refresh token with the desired scopes. Such a token can be used in conjunction with the refresh_token keyword argument using in initializing an instance of Reddit. A list of all possible scopes can be found in the reddit API docs

#!/usr/bin/env python

"""This example demonstrates the flow for retrieving a refresh token.

This tool can be used to conveniently create refresh tokens for later use with your web
application OAuth2 credentials.
