LISP MAINTENANCE AND DENDRAL MAINTENANCE

[Fisher]

	DENNIS WANTS ME TO PREPARE A SHORT REPORT ON HOW LISP IS MAINTAINED
SO THAT CHANGES IN LISP AND SLISP WILL CAUSE US AS LITTLE DIFFICULTY AS
POSSIBLE. I DON'T KNOW THAT THERE IS MUCH THAT WE CAN DO ABOUT LISP
BUT WE SHOULD BE ABLE TO WARN THE CHEMISTS THAT VERSION A AND B CAN'T LOAD
EACH OTHERS COMPILED FILES. THIS IS THE CASE CURRENTLY WITH SUBSYS LISP AND 
LISP LISP. THEREFORE IT WILL EVENTUALLY BE A PROBLEM. THE <LISP>CARHART.SAV
WHICH IS THE "SAME" AS <SUBSYS>SLISP ALSO CAN'T LOAD EACH OTHERS FILES.
