<?php
/**
* This script lets a command-line user start up the wiki engine and then poke
* about by issuing PHP commands directly.
*
* Unlike eg Python, you need to use a 'return' statement explicitly for the
* interactive shell to print out the value of the expression. Multiple lines
* are evaluated separately, so blocks need to be input without a line break.
* Fatal errors such as use of undeclared functions can kill the shell.
*
* To get decent line editing behavior, you should compile PHP with support
* for GNU readline (pass --with-readline to configure).
*
* This program is free software; you can redistribute it and/or modify
* it under the terms of the GNU General Public License as published by
