"""This example demonstrates using the file token manager for refresh tokens.
In order to run this program, you will first need to obtain a valid refresh token. You
can use the ``obtain_refresh_token.py`` example to help.
In this example, refresh tokens will be saved into a file ``refresh_token.txt`` relative
to your current working directory. If your current working directory is under version
control it is strongly encouraged you add ``refresh_token.txt`` to the version control
ignore list.
Usage:
EXPORT praw_client_id=<REDDIT_CLIENT_ID>
EXPORT praw_client_secret=<REDDIT_CLIENT_SECRET>
python3 use_file_token_manager.py
