- /**
- * 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).
