	As I understand it the Free Sofware Foundation did a free Yacc
called BISON, and also a free LEX still called "LEX".  I'm curious as to
why they changed the name of one and not the other, except that "Yacc"
lent itself to some word play as 'yak' and 'bison' are both ungulates
and nobody could think of something similar for 'lex' at the time.
	Anyway, Stuart D. Gathman says he hopes bison is being supplied
in binary, is that part of the requirement imposed by the Free Software
Foundation?  Did the FSF also provide LEX?  Weren't these posted to
Compuserve (I don't have a compuserve account but I heard from a friend

that they were there?).
	Assuming they are legally available are there other problems?
like do they work and are they documented?
