There are 7 directories that have source code in them:

	uniproc   -- contains the actual (uniprocessor) simulator code
	gi        -- the Suntools Graphics Interface code
	xgi       -- the X11 Graphics Interface code
	backprop  -- the back propagation library functions
	lib       -- library of commonly used user functions
	tools     -- connect tools (makebind, grabnames, etc.)
	ld        -- GNU linker to replace UNIX ld for dynamic linking.
			(Not recommended... we used it for a while until
			we figured out the appropriate combination of
			switches for the regular ld under SunOS 4.0.
			We include it here just in case you have a need.)
