Or we can `modernize it' by removing those things we no longer agree  
with, and document the bits of it that we don't like anymore in the  
manual.  Hopefully he'll release a new book with updated guidelines.   
If there are no useful things left, well, let's remove it (or remove  
the effects the option has).
