PRAW Environment Variables
**************************

The highest priority configuration options can be passed to a program
via environment variables prefixed with "praw_".

For example, you can invoke your script as follows:

   praw_username=bboe praw_password=not_my_password python my_script.py

The "username" and "password" provided via environment variables will
override any such values passed directly when initializing an instance
of "Reddit", as well as any such values contained in a "praw.ini"
file.

All Configuration Options can be provided in this manner, except for
custom options.
