One File Blog - Well, read the name

ofb.php

<?php
/*
 * One File Blog - OFB
 * Author: James "debug" Droste <me-@-jdroste.me>
 * ------
 * Untested, but it should be good to go.
 * Config items should be self-explanatory
 * ------ 
 * Use header.php and footer.php for your themeing needs
 * The post_(title|body|date) require a "%s" for where the content will be
 * post_date_format uses PHP's date function (php.net/date). See that page
 *    for the format
 * ------
 * Final notes:
 * One day (read: soon(TM)), I'll make a fully featured one, aiming to be one file
 * that is under maybe 10-15kbs. Should be fun :). (Not including website theme, only code)
