Documentation
This is a list of functions that format user objects for printing.
Each function is called in turn with three arguments: the object, the stream, and the print level (currently ignored). If it is able to print the object it returns true; otherwise it returns nil and the printer proceeds to the next function on the list.
This variable is not used at present, but it is defined in hopes that a future Emacs interpreter will be able to use it.
