			the file for details on the following changes:
			System names now package independent. Systems
			definitions will be loaded from file if not present.
			COMPILE-SYSTEM and LOAD-SYSTEM for naive users.
			Package name now "MAKE" to avoid naming conflicts.
			APPEND-DIRECTORIES now works with logical pathnames
			package (fixed other bugs as well). Cleaned up
			redefinition of REQUIRE. Versions. Global 
			*use-timeouts* to turn off timeout feature of
			Y-OR-N-P-WAIT. UNDEFSYSTEM, DEFINED-SYSTEMS,
			DESCRIBE-SYSTEM. :delete-binaries system operation.
			Fixed several bugs in COMPILE-AND-LOAD-OPERATION.
			Now knows when files were loaded. Added :load-only
			and :compile-only slots in components. Added
			#@ macro character definition. :private-file
			component type. Operations on systems
			(e.g., :compile and :load) now propagate to
			subsystems. Default definitions of PROVIDE/REQUIRE
			for CLtL2-compliant lisps.
MK      01/29/91 	(LOGICAL-PATHNAMES) Changed convert-file-function
			to better handle optional args, so (ed) and (dribble)
			should now work. Define and use lisp:nth-value.

			between physical and logical host names.
			lisp::file-name	specialized to CMU Common Lisp
			(accidentally forgot #+:cmu).
