<?php
/*
Flat-file login control
USAGE:
Simply require() this file at the very beginning of any page which is to be
login controlled. For logouts, you can have any such controlled page link to
itself with a ?logout=1 query string:
<a href="<?php echo $_SERVER['PHP_SELF']; ?>?logout=1">Log out</a>
see the "user-modifiable" attributes below for setting up your installation
FILES:
uses a plain text file for user data, one line per user, each line consisting
of:
0-n whitespaces
login_name
1-n whitespaces
md5-encoded_password
0-n whitespaces
*/

// User-modifiable:

// Do not modify below this line....
