I thought about this, but what stopped me was I kept thinking that one would 
want to set a preference in the /usr/bin/emacs file, and that would require 
modification of the file, or an /etc/ file to set preference which led be 
back to well, we have alternatives....

Of course, if we don't give a care what /usr/bin/emacs runs, so long as it 
runs, then we could keep the script as is and use this Provides method and 
move on.
