FUNCTION

NAME
        init_arg - parse a string passed by an autoloading object


LOCATION
	In certain autoloading objects.

SYNTAX
	void init_arg(string str);

DESCRIPTION
	Autoloading objects save a filename and an optional string (see
	query_auto_load(L)).  In most cases that string will be "".  If it
	is anything other than "", then when the autoloader is cloned when 
	the player logs on, the optional string is passed to init_arg().


NOTE
	Use this to save certain certain flags, conditions, and settings.
	
	If you use some sort of separator for options saved, make sure that
	players cannot set these tokens themselves.  The "^!" token is
	reserved for the separating of autoloaders in the player object.  Use
	of it will cause your object not to autoload.


EXAMPLE
	A completely arbitrary and useless example:

	/* This takes a sentence and prints out words on separated lines
	   when the player logs on */
	void init_arg(string str) {
	   write(implode(explode(str, " "),"\n"));
	}
