+/**
+ * PHP lacks an interactive mode, but this can be very helpful when debugging.
+ * 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).
