    The config file: #{etc}/pgbouncer.ini is in the "ini" format and you
    will need to edit it for your particular setup. See:
    http://pgbouncer.projects.postgresql.org/doc/config.html

    The auth_file option should point to the #{etc}/userlist.txt file which
    can be populated by the #{bin}/mkauth.py script.
